1
What is the role of the renal pelvis?
Collecting urine from the kidney
2
Where does the majority of water reabsorption occur in the nephron?
Proximal convoluted tubule
3
A medical student is conducting an experiment involving the diffusion of gases across a semipermeable membrane. In one chamber, the student places oxygen, and in the other chamber, there is a lower concentration of oxygen mimicking the environment of oxygen-poor blood flowing past alveoli in the lungs. What will happen to the oxygen molecules in this scenario?
Oxygen will move from the area of higher concentration to the area of lower concentration until equilibrium is reached.
4
What is required for active transport to occur?
Energy in the form of ATP
5
What is the primary functional unit of the kidney?
Nephron
6
Which of the following environments would cause a cell to swell due to osmosis?
Hypotonic solution
7
Which of the following statements best describes the role of sodium co- transporters in the reabsorption process occurring in the proximal convoluted tubule of the nephron?
Sodium co-transporters enable the reabsorption of sodium ions into the tubular cells via secondary active transport, often linked with the reabsorption of glucose or amino acids.
8
Where are the kidneys located?
Behind the peritoneum
9
What is the primary role of the Loop of Henle?
Concentrate urine
10
In which direction does water typically move during osmosis?
From a region of low solute concentration to high solute concentration
11
What is the primary function of the renal medulla?
Reabsorption of water and solutes
12
What is the name of the kidney structure that encloses the glomerulus?
Bowman's capsule
13
Which part of the nephron is responsible for filtration?
Glomerulus
14
Which process involves the movement of molecules from an area of higher concentration to an area of lower concentration?
Diffusion
15
Which part of the kidney contains the renal pyramids?
Medulla
16
What is the primary function of the proximal tubule?
Reabsorption of ions and nutrients
17
What is the primary role of the collecting ducts in the kidney?
Adjusting the reabsorption of water and electrolytes, and maintaining acid-base balance
18
In which part of the kidney is the majority of nephrons located?
Cortex
19
Which part of the nephron is impermeable to water?
Ascending limb
20
What is the name of the area where the renal artery, renal vein, and ureter enter and exit the kidney?
Hilum
