The Urinary System

Urinary System Functions:

-Removes waste from blood.

-Maintains blood pressure and volume.

-Maintains electrolyte (salt) levels and blood pH.

-Stimulates red blood cell production.

Urinary System Anatomy:

The urinary system consists of two _________________ that filter the blood, two ____________ that conduct urine away from the kidneys, a urinary ___________ to store the urine, and a ________________ to convey urine to the outside of the body.

Kidney Structure:

The kidney is a reddish brown, _________________- shaped organ 12 centimeters long; it is enclosed in a tough, fibrous ________________.

A medial depression in the kidney leads to a hollow renal ______________ into which blood vessels, nerves, lymphatic vessels, and the ureter enter.

Inside this space lies a funnel-shaped sac called the renal _____________ that is subdivided into tubes called major and minor ________________.

Two distinct regions are found within the kidney: an inner renal _______________ and an outer renal ___________.

Kidney Blood Vessels:

Renal arteries.

Renal veins.

Kidney Function:

Forty-five gallons of blood plasma pass through the kidneys every day (180 liters in 24 hours) and most of this fluid including the water and dissolve substances must be returned to the blood.

The kidneys function to regulate the volume, electrolyte levels (salts), and pH of body fluids and removes wastes from the blood.

Describe the contents of urine:

The kidneys also help control the rate of ___________ blood cell formation by secreting the hormone erythropoietin.

The kidneys also regulate ______________________________ by secreting renin.

Nephron: The nephron is the functional and structural unit of the kidney!

A kidney contains one million nephrons, each of which consists of a renal _________________and a renal ____________________.
