urinary system labeled function and organs
The urinary system is composed of the kidneys, ureters, bladder urine system and urethra. Blood from the heart travels down the aorta where it enters the kidney via the renal arteries. The kidney acts as a filter and regulator, removing waste products (urea) and balancing glucose, electrolytes (salt, potassium and other minerals) and water levels in the blood. Urine from the kidney flows through the ureter to the bladder, where leaves the body via the urethra.

Functions of the Urinary System
One of the major functions of the Urinary system is the process of excretion. Excretion is the process of eliminating,
from an organism, waste products of metabolism and other materials that are of no use. The urinary system
maintains an appropriate fluid volume by regulating the amount of water that is excreted in the urine. Other aspects
of its function include regulating the concentrations of various electrolytes in the body fluids and maintaining normal
pH of the blood. Several body organs carry out excretion, but the kidneys are the most important excretory organ.
The primary function of the kidneys is to maintain a stable internal environment (homeostasis) for optimal cell and
tissue metabolism. They do this by separating urea, mineral salts, toxins, and other waste products from the blood.
They also do the job of conserving water, salts, and electrolytes. At least one kidney must function properly for life
to be maintained.
Six important roles of the kidneys are:
Regulation of plasma ionic composition.
Ions such as sodium, potassium, calcium, magnesium, chloride,
bicarbonate, and phosphates are regulated by the amount that the kidney excretes.
Regulation of plasma osmolarity.
The kidneys regulate osmolarity because they have direct control over how many
ions and how much water a person excretes.
Regulation of plasma volume.
Your kidneys are so important they even have an effect on your blood pressure. The
kidneys control plasma volume by controlling how much water a person excretes. The plasma volume has a direct
effect on the total blood volume, which has a direct effect on your blood pressure. Salt(NaCl)will cause osmosis to
