Knowing More about Kidney Anatomy

Knowing kidney anatomy can help you understand kidney function more closely. The reason is, each part of the kidney has its own role in supporting kidney function for the body. Check out the following explanation of the anatomy of the kidney and how it works

Kidneys are a pair of bean-shaped organs with the size of approximately the size of a fist. The kidneys are located at the back of the abdominal cavity or lower back area, one to the right of the spine and the other to the left.

The function of the kidneys is very heavy and important for the human body, including filtering blood, removing metabolic waste in the form of urine, controlling body fluid balance, and regulating the body's s alt or electrolyte balance.

Just like other organs of the body, the anatomy of the kidney can describe the performance of each part of the kidney in carrying out its functions.

Kidney Anatomy and How It Works

The right kidney and the left kidney are not located at the exact same height because the abdominal cavity is asymmetrical. On the right side of the abdomen there is a liver organ, so that the position of the right kidney is lower than the left kidney. The size of the right kidney is also smaller than the left kidney.

The kidney of an adult male is approximately 11 cm, while the kidney of an adult female is 10 cm. Although small, the kidneys consist of many parts that play a major role in carrying out their functions.Anatomically, there are four main parts that support kidney function, namely:


Nephron is an important part of the kidney which is in charge of filtering blood, then taking its nutrients and removing the waste products of metabolism.

There are about 1 million nephrons in each kidney. Each nephron consists of a structure that contains the renal corpuscle (malpighian body) and the renal tubule. In more detail, the nephron is composed of the glomerulus, Bowman's capsule, the proximal convoluted tubule, the loop of Henle and the distal convoluted tubule.

In nephrons, blood will flow towards the renal corpuscle. After that, the protein in the blood will be absorbed by the glomerulus, while the remaining fluid will flow into the collecting duct or collecting duct. Then, some will be reabsorbed into the blood, including water, sugar and electrolytes.

renal cortex or renal cortex

The renal cortex is located on the outside of the kidney. It is surrounded by a layer of fatty tissue known as the renal capsule or renal capsule. The renal cortex and capsule serve to protect the internal structures of the kidney.

renal medulla or renal marrow

The renal medulla is a soft tissue found in the kidney. It contains the renal pyramids (pyramids renalis) and collecting ducts, which are pathways for filtered fluid to exit the nephron to the next anatomical structure of the kidney, namely the renal pelvis.

renal pelvis or renal pelvis

The renal pelvis is the deepest part of the kidney. The renal pelvis is shaped like a funnel and acts as a conduit for water from the kidneys to the bladder.

Composed of renal calyces (renal calices), the renal pelvis serves as a storage area for urine before it is transported to the bladder through the ureters.

Given its very important function for the body, you should maintain kidney he alth. Get enough water every day, consume he althy foods that include vegetables, fruits, and whole grains, maintain an ideal body weight, and avoid smoking and consuming alcoholic beverages.Don't forget to exercise regularly and avoid taking drugs outside of the doctor's advice.
