What is the primary function of the kidney in the body?

The kidney is essential and necessary, and the kidneys are responsible for excreting body wastes through urine. You will be informed about the kidneys’ function, anatomy, and primary features in the following.

What is a kidney, and what is its role in the body?

The kidneys are a complex organ that is responsible for excreting body wastes through urine. People usually have two kidneys located in the back of the abdomen, next to the spine, and below the ribs. The kidneys are in the form of beans, and their existence is essential because life is not possible without their proper functioning. However, due to scientific advances, doctors use methods such as dialysis or transplantation when necessary. In addition to producing urine, the kidneys are involved in many other processes, such as regulating blood pressure.

Healthy kidney function and function:

Disposal of waste and excess liquids:

The kidneys act as a filter in removing waste and excess body fluids and excrete about 200 curates of blood to about 1 to 2 curates of urine per day. The office contains waste and excess fluids that can prevent disease by disposing of these wastes.

Blood pressure control:

The kidneys need blood pressure to function correctly. If the blood pressure is low, the kidneys can ask for more blood pressure, or if it seems too much, it can lower the blood pressure by controlling fluid levels and making a hormone that causes blood vessels to constrict.

Making red blood cells:

The kidneys make a hormone called erythropoietin. Erythropoietin commands the bone marrow to make red blood cells. Red blood cells carry oxygen from the lungs to meet all of your body’s needs and energy for your daily activities.

Bone health:

The kidneys are the active form of vitamin D, and people need vitamin D to absorb calcium and phosphorus. Calcium and phosphorus are essential minerals for building strong bones. The kidneys also balance calcium and phosphorus levels, so the body provides the amount it needs.

Control of PH levels:

pH is an acid-base scale. The kidneys retain chemicals that control and balance acid levels. By breaking down cells, acid is made. The foods you eat can increase or decrease the amount of acid in your body.

Kidney Anatomy:

As we mentioned, the kidneys are bean-shaped, one side is concave, and the other side is convex. The renal artery enters the concave part and carries the blood with the body waste products that go to the kidneys. Kidney vessels and ureters or ureters are also removed from that area.

Anatomy and main components of the kidney

The kidney has two main parts: the cortex and the medulla.

The cortex is the outermost part and the part that receives the most blood flow. This is mainly responsible for filtration and reabsorption. Also, it contains almost all glomeruli, which we will explain below. (Common Kidney Disease In Women + Prevention And Treatment)

The medulla consists of a set of structures that are responsible for directing kidney urine to the trachea. The urinary tract is a tube that goes to the bladder, stores urine, and then destroys it.

The glomerulus filters the blood:

As blood flows to the nephron, it enters a group of tiny blood vessels called glomeruli. The glomerulus’ thin walls allow molecules, waste products, and smaller liquids (mostly water) to enter the tube. Larger molecules, such as proteins and blood cells, remain in the blood vessel.

The ureter or urethra returns the nutrients to the blood and removes the waste products.

A blood vessel moves along the tube. As the filtered fluid moves along the tube, the blood vessel absorbs almost all of the water, along with the minerals and nutrients the body needs. The tube helps remove excess acid from the blood. Liquids and waste products left in the tube are converted into urine.

How is the blood flow in the kidneys?

Blood flows through the renal artery to the kidney. This large blood vessel splits into smaller and smaller blood vessels until the blood reaches the nephron. In nephrons, your blood is filtered by small glomerular blood vessels and then excreted through the renal artery.

Facts About The Kidneys

As you are aware, the human body has different devices and components, each of which plays its role, which results in the survival and mobility of the individual.

Therefore, it can be understood that all body parts must remain healthy for the body to be in the ultimate state of health. By damaging one part, other parts will get into trouble, which is something irreparable and unpleasant.

Among the body’s main components, we can mention the kidneys, which are undoubtedly one of our body’s essential organs, which play an essential role in filtering and purifying the blood and removing and eliminating waste products from the body. In other words, the kidneys are the same size as mobile phones, which have the same shape and anatomy as beans.

However, this vital organ of the body has hidden truths that we may not know about, and the main reason could be our inattention to this vital organ.

What do you know about kidney function?

1- Blood flow in the kidneys is more than blood flow in the heart and brain.

2- Kidneys are 11.5 cm long.

3- The kidneys are not bigger than a computer mouse and are the same size as old phones.

4- Kidneys usually weigh 113 to 170 grams.

5- In adults, the kidneys make up only 0.5% of the body.

6- Only one healthy kidney can do the work of both kidneys.

7- At least 1 to 2 million people, which is the kidney’s building block, are formed in each kidney.

8- Although the kidneys make up 0.5% of the body, they pass more blood than other parts of the body, with about 25% of the blood that the heart pumps into the kidneys.

9- When people reach 40, their body nephrons decrease by 1% per year!

10- Nephrons try to get longer over time!

11- If we take the nephrons out of the kidneys, their length will reach 16 km!

12- If you remove one of the two kidneys and the second kidney function is reduced by 75%, there is hope for life, and you can stay healthy, which is known as “hypertrophy.”

13- The whole blood of the body passes through the kidneys 400 times a day and is checked.

14- If the kidneys’ blood pressure decreases, they start sending signals to other parts of the body, and then the arteries, after receiving this message, start to narrow to increase the pressure.

15- If the amount of oxygen in the blood decreases, the kidneys can also feel it, increasing red blood cells’ production to eliminate it by producing a hormone.

16- The kidneys are connected to the bladder, where urine is stored, and the bladder can retain this fluid for 1 to 8 hours. If the bladder is overfilled, a nerve message is sent to the brain to empty immediately. Be.

17- Kidneys can produce vitamin D !! The main organ responsible for producing vitamin D in the body is the skin, which is transferred to the liver if the skin is unable to function.

18- Children who are born with one kidney, over time, this kidney grows enough to perform the function of two kidneys alone.

19- Normally, our kidneys can produce about 1.5 liters of urine during the day.

20- Kidney failure can lead to anemia.

21- High rates of diabetes can lead to kidney damage.

22- The first successful kidney transplant was performed by Joseph Smith in Boston in 1954.

A change if it is a sign of kidney failure!

The kidney is one of the body’s organs that can excrete waste products and cleansing the body. Therefore, causing kidney failure problems and kidney failure can be dangerous and damage the body’s health.

What are the symptoms of kidney failure?

The kidneys are one of the organs that play a crucial role in cleansing and purifying the body and remove waste products from the body in the best possible way. In most cases, kidney failure is caused by other health problems that cause permanent damage to the kidneys.

When the kidneys are damaged, they may not work well enough. If the kidneys’ damage gets worse and the kidneys are less and less able to do their job, you will get severe chronic kidney disease, and then kidney failure is the last stage of chronic kidney disease. Therefore, kidney failure is also a kidney disease. The last stage is called ESRD for short.

Diabetes is the most common cause of ESRD, and high blood pressure is the second most common cause.

Other problems that can cause kidney failure include:

  • Autoimmune diseases such as lupus and IgA nephropathy
  • Genetic diseases (diseases with which you are born), such as a kidney disease
  • Nephrotic syndrome
  • Urinary tract problems
  • Sometimes the kidneys can stop working suddenly (within two days) or fail to improve.
  • This type of kidney failure is called severe kidney damage or acute kidney failure.

Common causes of acute renal failure include:

  • heart attack
  • Illegal and excessive drug use
  • Insufficient blood reaches the kidneys
  • Urinary tract problems
  • This type of kidney failure is not always permanent.

The kidneys may return to normal or become almost normal with treatment unless you have other serious health problems. Having a health problem that can lead to kidney failure does not mean that you will have kidney failure.

Having a healthy lifestyle and working with your doctor to control these health problems can help your kidneys work as much as possible.

Symptoms of chronic kidney disease:

Chronic kidney disease (CKD) usually gets worse slowly and may not go away until the kidneys are badly damaged. In the later stages of CKD, as you get closer to kidney failure (ESRD), you may notice symptoms of waste products and excess fluid in your body.

If you have kidney failure, you may notice one of the following symptoms:

  • Itching
  • Muscle cramps
  • nausea and vomiting
  • Do not feel hungry
  • Swelling of the feet and ankles
  • Excessive or insufficient urine
  • Difficulty breathing
  • Difficulty sleeping

If the kidneys suddenly stop working (severe failure), you may notice one of the following symptoms:

  • stomach ache
  • backache
  • Diarrhea
  • Fever
  • Nosebleed
  • Boiling
  • Vomit

Having one or more of the above symptoms may be a sign of severe kidney problems. You should see your doctor if you notice any of these symptoms. If you are at risk for kidney disease due to high blood pressure, diabetes, a family history of kidney failure, or passing the age of 60, it is essential to get tested for kidney disease every year.

Complications Symptoms of kidney failure and difficulty

You become more tired, have less energy, or have difficulty concentrating. A severe decrease in kidney function can lead to the accumulation of toxins and impurities in the blood.

This can make people feel tired and weak and make it difficult for them to concentrate. Another complication of this disease is anemia, which can cause weakness and fatigue.

If you have kidney problems, you will have trouble sleeping

When the kidneys do not purify properly, toxins remain in the blood instead of leaving the body through the urine. This can make it difficult to sleep. There is also a link between obesity and chronic kidney disease, and shortness of breath is more common in people with chronic kidney disease than in the general population.

If you have kidney problems, you have dry and itchy skin

Healthy kidneys do many important things. They remove waste products and excess fluid from the body and help build red blood cells, help maintain bones, and work to maintain the right amount of minerals in your blood. Dry skin and itchy skin can be a sign of bone and mineral disease, often associated with advanced kidney disease, when the kidneys are no longer able to maintain the proper balance of minerals and nutrients in your blood.

You feel the need to urinate more. If you feel the need to urinate more, this could be a sign of kidney disease. When the filters are damaged, this increases the urge to urinate; sometimes, this may be a sign of urinary tract infection or an enlarged prostate in men.

Seeing blood in the urine if there is a problem with the kidneys

Healthy kidneys usually hold blood cells in the body when they filter waste products from the blood to make urine, but when the kidney filters are damaged, they begin to leak into the urine. In addition to kidney disease symptoms, blood in the urine can sign a tumor, kidney stone, or infection.

Your urine is foamy

Excessive bubbles in the urine – especially those that require you to use a siphon several times to get rid of them – indicate the presence of protein in the urine. This foam may look like foam, just as the usual protein in urine, albumin, is the same protein found in eggs.

The area around your eyes is puffy

In previous sections on Moist Health, protein in urine is an early sign that kidney filters are damaged and allows the protein to leak into the urine. This puffiness around your eyes can be because your kidneys leak a lot of protein into the urine instead of keeping it in the body.

Swelling of the wrists and soles of the feet with decreased kidney function

Decreased kidney function can lead to sodium retention, which causes swelling of the feet’ wrists and soles. Inflammation of the lower extremities can also be a sign of heart disease, liver disease, and chronic foot disease.

You have a poor appetite due to decreased kidney function

This is a prevalent symptom, but toxins accumulation due to decreased kidney function can be one reason.

If you have a kidney problem, your muscles will ache

Electrolyte imbalance can be caused by kidney dysfunction. For example, low levels of calcium and poorly controlled phosphorus can lead to abdominal pain.
