(NO COPY/PASTING)

1) List at least 4 functions of the Urinary System.

b. Reaborsption

c. Secretion

d. Activation of Vitamin D

2) What is the role of the renal artery?

a. Transports oxygenated blood from the heart and aorta to the kidneys

3) What is the function of the nephron?

a. Filtration of blood and the reabsorption of secreted materials

4) What does the capsule do?

a. It supports and protects the kidney

5) What is the function of the cortex?

a. It is the main sight for filtration, reabsorption, and secretion

6) What are renal pyramids?

a. Triangular shaped units in the medulla that house the loops of Henle and collecting ducts of the nephron. This is also the site for the counter-current system that concentrates salt and conserves water and urea

a. The glomerulus is surrounded by the Bowman’s Capsule

10) How are kidney stones formed?

a. Crystalization od calcium, magnesium, or uric acid salts that are precipitated down to the renal pelvis
