Question

1. what term is used to describe the blood vessels which take blood away from the bowmans capsule in the kidney?

afferent
collecting
distal
efferent

1. concentration of urine occurs in the renal \medullary\ zone. based on its name, where is the medullary zone located in the kidney?

glomerular capillaries
inner marrow - like pyramids
outer bark area
proximal tubules

Explanation:

• For question 50: Afferent vessels bring blood to the glomerulus in the Bowman's capsule, while efferent vessels take blood away. Collecting is related to urine - not blood vessels from Bowman's capsule, and distal is a part of the tubule system.
• For question 51: The term "medullary" is related to the inner part of an organ. In the kidney, the medullary zone consists of inner marrow - like pyramids. Glomerular capillaries are in the cortex, the outer bark - like area is the cortex, and proximal tubules are also in the cortex.

Answer:

1. D. efferent
2. B. inner marrow - like pyramids
