Answer:

The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state. In humans and other amniotes (mammals, birds and reptiles) most of these substances leave the body as urine and to some degree exhalation, mammals also expel them through sweating.

Answer:

The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes.

The Excretory system is responsible for the elimination of wastes produced by homeostasis.

There are several parts of the body that are involved in this process, such as sweat glands, the liver, the lungs and the kidney system.

Every human has two kidneys.

Each kidney is made up of three sections: the renal cortex, the renal medulla and the renal pelvis.

The blood arrives at the kidney via the renal artery, which splits into many afferent arterioles.

These arterioles go to the Bowman's Capsules of nephrons, where the wastes are taken out of the blood by pressure filtration.

Peritubular capillaries also surround the nephron so substances can be taken in and out of the blood.

The renal cortex is the outer layer of the kidney and the medulla is the inner layer of the kidney.

The renal pelvis takes urine away from the kidney via the ureter.

Both of the ureters lead the urine into the body's only urinary bladder, which expands and sends nerve impulses when full.

From there, urine is expelled through the urethra and out of the body.
