Options are tubular secretion, glomerular filtration, or tubular reabsorption.

1. Opposite process to tubular reabsorption

2. Water and solutes are forced from the blood into the glomerular capsule of the nephron

3. Water, glucose, amino acids, and needed ions are moved from the filtrate back into the blood

4. Aldosterone promotes sodium and thus water to move from the filtrate through the tubule cells into the blood

5. Antidiuretic hormone (ADH) promotes the movement of water from the filtrate back into the blood of the peritubular capillaries

6. Unneeded substances such as potassium, urea, and creatinine are moved from the blood of the peritubular capillaries into the filtrate

Explain in simple terms how each nephron acts as a tiny blood filter as it produces urine. Where do most waste products from the blood end up? Where do most essential items of the blood end up? How do filtration, reabsorption, and secretion affect the movement of these materials in or out of the nephron?

(a) Afferent arteriole​(c) Efferent arteriole
(b) Vasa recta​(d) Peritubular capillaries
2. Which of the following CORRECTLY describes the flow of filtrate through the renal tubule?
(a) Glomerulus à Distal convoluted tubule à Ascending limb of nephron loop à Descending limb of nephron loop à Proximal convoluted tubule à Collecting duct
(b) Glomerulus à Proximal convoluted tubule à Descending limb of nephron loop à Ascending limb of nephron loop à Distal convoluted tubule à Collecting duct
(c) Glomerulus à Proximal convoluted tubule à Ascending limb of nephron loop à Descending limb of nephron loop à Distal convoluted tubule à Collecting duct

(a) Elimination​(c) Secretion
(b) Reabsorption​(d) Filtration
4. Which of the following is TRUE about the reabsorption process in the proximal convoluted tubule?

(b) Negatively charged ions (e.g. chloride) are transported out of the tubule in response to the movement of sodium
(c) Water is reabsorbed into the peritubular capillaries because of the increased osmotic pressure
(d) All of the above
5. Which of the following statements is FALSE about the glomerulus and the processes that occur there?
(a) Capsular hydrostatic pressure refers to the pressure of fluid pressing on the capsule and opposes filtration
(b) Net filtration pressure in the glomerulus is the difference between forces favoring filtration and forces opposing filtration
(c) Blood from the afferent arteriole is filtered by size when it enters the glomerulus because of the many fenestrae
(d) Vasoconstriction of the efferent arteriole lowers glomerular filtration rate
6. The descending limb of the nephron loop is impermeable to water while the ascending limb of the nephron is permeable to water.
(a) True​(b) False
