The kidneys are a pair of bean-shaped organs that are found in all vertebrates. They remove waste products from the body, maintain the balance of electrolyte levels, and regulate blood pressure.
The kidneys have long been regarded as important organs. The Ancient Egyptians left only the brain and kidneys in position before embalming a body, inferring some higher value.
Fast facts on the kidneys:-
Here are some key points about kidneys. More detail and supporting information is in the main article.
•
The kidneys help maintain the body's internal balance, including blood pressure.
•
Dialysis is used if the kidneys lose most of their function.
•
The kidneys secrete a number of hormones
•
Some analgesics can damage the kidneys.
Structure:-
The kidneys play a role in maintaining the balance of body fluids and regulating blood pressure, among other functions.
The kidneys are located at the back of the abdominal cavity, one on each side of the spine. Due to the asymmetry caused by the liver, the right kidney is generally slightly smaller and lower than the left.
Each kidney weighs 125 to 170 grams (g) in males and 115 to 155 g in females.
Surrounding each kidney is a tough, fibrous renal capsule and, beyond that, two layers of fat that serve as protection. On top of each kidney are the adrenal glands.
Inside the kidneys are a number of pyramid-shaped lobes. Each consists of an outer renal cortex and an inner renal medulla. Flowing between these sections are nephrons, the urine-producing structures of the kidneys.
Blood enters the kidneys through the renal arteries and leaves through the renal veins. The kidneys are relatively small organs, but they receive up to 25 percent of the heart's output.
Each kidney excretes urine through a tube called the ureter that leads to the bladder
Function:-
The main role of the kidneys is that of homeostasis. This means they manage fluid levels, electrolyte balance, and other factors that keep the internal environment of the body within constant parameters.
