Question 1

Match the renal functions, labelled a. through d., with the correct terms.

B)movement of substances from the glomerular capillary blood into the tubular lumen
C)everything filtered or secreted that is not subsequently reabsorbed
D)movement of substances from the tubular lumen into the peritubular capillary blood

Accepted Answer

Tubular secretion refers to the process of moving substances from the peritubular capillary blood into the tubular lumen, which helps in the elimination of waste products and the regulation of blood pH.

B)movement of substances from the glomerular capillary blood into the tubular lumen
C)everything filtered or secreted that is not subsequently reabsorbed
D)movement of substances from the tubular lumen into the peritubular capillary blood

Accepted Answer

Urine excretion refers to the process of removing waste and excess substances from the body. It includes everything that is filtered from the blood or secreted into the tubules of the kidneys that is not reabsorbed back into the bloodstream, hence matching with option C.

Question 16

Match the renal functions, labelled a. through d., with the correct terms.
-glomerular filtration
A)movement of substances from the peritubular capillary blood into the tubular lumen
B)movement of substances from the glomerular capillary blood into the tubular lumen
C)everything filtered or secreted that is not subsequently reabsorbed
D)movement of substances from the tubular lumen into the peritubular capillary blood

Accepted Answer

Glomerular filtration specifically refers to the process where substances move from the glomerular capillary blood into the tubular lumen. This is a key step in the formation of urine, where blood is filtered at the glomerulus, allowing water and solutes to enter the renal tubule while preventing the passage of blood cells and large proteins.

Question 20

Match the renal functions, labelled a. through d., with the correct terms.

A)movement of substances from the peritubular capillary blood into the tubular lumen
B)movement of substances from the glomerular capillary blood into the tubular lumen
C)everything filtered or secreted that is not subsequently reabsorbed
D)movement of substances from the tubular lumen into the peritubular capillary blood

Accepted Answer

Tubular reabsorption refers to the process where substances move from the tubular lumen back into the bloodstream via the peritubular capillaries, which is accurately described in option D.
