Study Notes

Main Organs of Excretion

The four main organs involved in the process of excretion are the lungs, skin, liver, and kidneys.

Structure of the Kidneys

The kidneys are bean-shaped organs connected by the renal artery and renal vein.

Urinary System

Urine flows from the kidneys into the urinary bladder through ureters.
The urinary bladder is a spherical organ located below the kidneys.
Urine exits the body through the urethra.

Blood Vessels

The abdominal aorta and inferior vena cava are two key blood vessels in the excretory system.

Functions of the Excretory System

Waste products are removed from the body through excretion.
Waste products in the blood are formed into urine in the body.
Urine is secreted out of the body through the urethra.
