Question 1

Which structure labeled in the first image is responsible for collecting urine from the renal pyramids and channeling it toward the renal pelvis?

Accepted Answer

Minor calyx (F)

Question 2

In the second image, which vessel (labeled) directly receives blood from the arcuate artery?

Accepted Answer

Cortical radiate artery (D)

Question 3

Referencing the third image, which structure is responsible for reabsorbing water and solutes from the filtrate and secreting substances into it?

Accepted Answer

Proximal convoluted tubule (D)

Question 4

In the fourth image, which process is represented by arrow 2, and what is its physiological significance?

Accepted Answer

Tubular reabsorption; it reclaims substances the body needs from the filtrate back into the blood.

Question 5

In the fifth image, which component of the filtration membrane (A, B, or C) contains fenestrations that allow all blood components except blood cells to pass through?

Accepted Answer

A (Glomerular capillary endothelium)

Question 6

Using the sixth image, calculate the net filtration pressure (NFP) in the glomerulus using the equation $$NFP = HP_{gc} - (HP_{cs} + OP_{gc}). $$What is the NFP value?

Accepted Answer

$$10\ 	ext{mm Hg}$$

Question 7

In the seventh image, what is the main driving force for water movement between the vasa recta and the surrounding interstitial fluid?

Accepted Answer

Osmosis

Question 8

In the eighth image, which structure (A, B, or C) stores urine temporarily?

Accepted Answer

B (Urinary bladder)

Question 9

Refer to the ninth image. Which compartment (A, B, C, or D) represents the intracellular fluid (ICF) compartment?

Accepted Answer

D

Question 10

Using the equation in the tenth image, calculate the milliequivalents per liter ($$mEq/L) $$for a plasma sodium ion ($$Na^+) $$concentration of $$3270\ 	ext{mg/L}$$ with an atomic weight of $$23\ 	ext{mg/mmol}$$ and a charge of $$+1.$$

Accepted Answer

$$142\ mEq/L$$

Question 11

Refer to the eleventh image. If plasma $$H^+$$ concentration rises, in which direction does the equation shift?

Accepted Answer

Shifts to the left

Question 12

Based on the twelfth image, which acid-base disturbance is characterized by a decrease in pH, an increase in $$P_{CO_2$}$$, and an increase in $$HCO_3$$^-$$ if compensating?

Accepted Answer

Respiratory acidosis

Question 13

In the thirteenth image, which structure (labeled) is the site of sperm production?

Accepted Answer

D (Testis)

Question 14

Refer to the fourteenth image. At what stage of life does sperm production begin in males?

Accepted Answer

Puberty

Question 15

In the fifteenth image, which structure (labeled) is the site where fertilization typically occurs?

Accepted Answer

D (Uterine tube)

Question 16

In the sixteenth image, which structure (labeled) is the functional layer of the endometrium that is shed during menstruation?

Accepted Answer

G (Endometrium)

Question 17

Refer to the seventeenth image. What stage of follicle development is shown?

Accepted Answer

Vesicular follicle
