Urinary system review

Question 1

know in order the vessels through which blood flows through the nephron

Answer 1

renal artery > afferent arteriole > glomerulus > efferent arteriole > peritubular capillary network > renal vein

Question 2

know in order the tubes through which filtrate flows through the nephron

Answer 2

glomerular capsule (Bowman’s capsule) > proximal tubule > loop of the nephron (loop of Henle) > distal tubule > collecting duct.

Question 3

Urinary Tract Infection

Answer 3

usually caused by E. coli entering the urinary tract. Most common in women. women have shorter urethras so shorter distance for bacteria to get in.

Question 4

Kidney stones

Answer 4

if it gets large can block the renal pelvis or ureter. Causes backflow into nephrons, causing damage.

Question 5

List the three stages of urine formation in the order in which they occur.

Answer 5

Glomerular filtration, tubular reabsorption, tubular secretion

Question 6

What is the description and what is moved in the process of Glomerular filtration?

Answer 6

filtering of blood. Nutrients, wastes, salts, and water are filtered.

Question 7

What is moved and wheres does tubular reabsorption occur?

Answer 7

Fibrate is reabsorbed from the tubules into the peritubular capillary network. Water, nutrients, and glucose are moved.

Question 8

what is moved in tubular secretion?

Answer 8

ions (such as H+), pH.
