Urinary System

Question 1

Functions of the Urinary System

Answer 1

Waste Elimination, Osmoregulation of blood and water, Hormone secretion

Question 2

Renal Artery

Answer 2

Blood flows from heart into kidney through this artery

Question 3

Renal Vein

Answer 3

Blood drains from the kidney through this vein

Question 4

Nephron

Answer 4

Functional and structural unit of a kidney

Question 5

Renal Corpuscle

Answer 5

One of two parts of a nephron. Consists of glomerulus and glomerular capsule (bowman’s capsule)

Question 6

Glomerulus

Answer 6

Capillary bed that functions as a filtration system.

Question 7

Bowman’s Capsule

Answer 7

Surrounds the glomerulus

Question 8

Renal tubule

Answer 8

a duct that connects to the glomerulus and terminates at the tip of the medullary pryamid

Question 9

Glomerular filtration

Answer 9

Blood enters kidney through renal artery, artery branches into capillaries which flow into the glomerulus, blood pressure forces water and solutes to diffuse from blood across capillary walls and through the bowman’s capsule into the tubule

Question 10

Proximal tubule

Answer 10

Major site of reabsorption of water and solutes

Question 11

Loop of Henle

Answer 11

Another site of reabsorption that comes after the proximal tubule

Question 12

Distal convoluted tubule

Answer 12

Comes after the loop of Henle. Reabsorption and secretion occurs here

Question 13

Collecting duct

Answer 13

Final segment, collects urine

Question 14

Antidiuretic Hormone (ADH)

Answer 14

Secreted from the posterior pituitary gland

Regulates urine concentration and volume by controlling how much water is reabsorbed in the tubules of the nephrons
