Importance of Reabsorption
Reabsorption is an important process in the kidney. Maybe this is the process of the Nephrons, but still, it is considered one of the most important processes in the kidney. It is seen that daily kidney helps to return a good amount of the essential elements to the body. Daily, nearly 99% of the filtered substances are returned to the body. Only one percent of the element that is filtered is removed. So, if those elements are not returned to the body, then there will be a serious essential elements crisis in the body. The body will not perform well. And there will be an intense need for the elements inside of the body. So, Reabsorption helps to maintain balance in the body. This is the largest process of urine formation than the other processes. Without the Reabsorption process, instead of 1.8 Littre/Day substances, 180 Littre/Day substances will be removed from the body. And this is a very high loss of the body.
Reabsorption in Kidney
The kidney is the organ that helps to eliminate harmful substances from the body. The process that helps to eliminate those substances is known as the excretion process. So, the kidney is an excretory organ. This organ helps to balance the substances in the body. The human body also has a kidney. In the human body, there are two kidneys are present. They are situated in the posterior wall of the abdomen cavity. They are situated on both sides of the vertebral column. These bean-shaped organs play an important role in the human body.
If the kidneys are intersects in two parts, there two major divisions can be witnessed. They are the Cortex & Medulla. The cortex is the region outside of the kidney. They are the outer portion of the kidney. And the inner part is known as the Medulla. There are some pyramids-like structures are present. They are known as the Medulla Pyramid. The kidney has a functional unit. This is known as the Nephron. There are millions of nephrons are present in the Kidney. Whatever function is being executed by the kidney; the whole functions are executed by the Nephrons.
