Q: If a patient has a tidal volume ($$TV) of 500 mL$$, an inspiratory reserve volume ($$IRV) of 3000 mL$$, and an expiratory reserve volume ($$ERV) of 1200 mL$$, what is their vital capacity ($$VC$$)?

$$VC = 500 + 3000 + 1200 = 4700\ \text{mL}$$

Q: A patient has a glomerular hydrostatic pressure ($$HP_g) of 55 $$mmHg, an osmotic pressure ($$OP_g) of 30 $$mmHg, and a capsular hydrostatic pressure ($$HP_c) of 15 $$mmHg. What is their net filtration pressure ($$NFP$$)?

$$NFP = 55 - (30 + 15) = 10\ \text{mmHg}$$

Question 1

Which chamber is shared by both the respiratory and digestive systems?

Accepted Answer

Pharynx

Question 2

During sympathetic stimulation, what happens to the diameter of the bronchioles in the respiratory system?

Accepted Answer

Bronchioles dilate

Question 3

Which equation correctly calculates the vital capacity ($$VC) of $$the lungs?

Accepted Answer

$$VC = TV + IRV + ERV$$

Question 4

If a patient has a tidal volume ($$TV) of 500 mL$$, an inspiratory reserve volume ($$IRV) of 3000 mL$$, and an expiratory reserve volume ($$ERV) of 1200 mL$$, what is their vital capacity ($$VC$$)?

Accepted Answer

$$VC = 500 + 3000 + 1200 = 4700\ 	ext{mL}$$

Question 10

Which structure is the site of filtration in the kidney?

Accepted Answer

Glomerulus

Question 11

Which equation best represents the net filtration pressure ($$NFP) in $$the glomerulus?

Accepted Answer

$$NFP = (HP_g) - (OP_g + HP_c)$$

Question 12

A patient has a glomerular hydrostatic pressure ($$HP_g) of 55 $$mmHg, an osmotic pressure ($$OP_g) of 30 $$mmHg, and a capsular hydrostatic pressure ($$HP_c) of 15 $$mmHg. What is their net filtration pressure ($$NFP$$)?

Accepted Answer

$$NFP = 55 - (30 + 15) = 10\ 	ext{mmHg}$$
