Question 4

A patient has a hematocrit of 40%. If their total blood volume is 5 liters, what is the volume of red blood cells?

Accepted Answer

2 liters

Question 5

Which equation correctly represents cardiac output ($$CO) in $$terms of heart rate ($$HR) $$and stroke volume ($$SV$$)?

Accepted Answer

$$CO = HR 	imes SV$$

Question 6

During vigorous exercise, which physiological change occurs in blood vessels supplying skeletal muscles?

Accepted Answer

Vasodilation increases blood flow to muscles.

Question 7

Which structure is responsible for filtering lymph and initiating immune responses?

Accepted Answer

Lymph nodes

Question 8

A person inhales deeply. Which equation best represents the relationship between tidal volume ($$TV$$), inspiratory reserve volume ($$IRV$$), and vital capacity ($$VC$$)?

Accepted Answer

$$VC = TV + IRV + ERV$$

Question 9

Which digestive organ is primarily responsible for nutrient absorption?

Accepted Answer

Small intestine

Question 10

A patient has a metabolic disorder affecting the breakdown of glucose. Which pathway is most likely impaired?

Accepted Answer

Glycolysis

Question 11

Which equation represents the calculation of glomerular filtration rate ($$GFR) in $$the kidneys?

Accepted Answer

$$GFR = K_f 	imes (P_{GC} - P_{BS} - \pi_{GC})$$

Question 12

A patient is dehydrated. Which hormone will be released to increase water reabsorption in the kidneys?

Accepted Answer

Antidiuretic hormone (ADH)

Question 13

Which electrolyte is most important for maintaining the resting membrane potential in neurons?

Accepted Answer

Potassium ($$K^+)$$

Accepted Answer

Testes

Question 17

Which of the following is a multi-step process involving both the innate and adaptive immune systems?

Accepted Answer

Question 18

A patient with chronic kidney disease is unable to excrete hydrogen ions efficiently. What acid-base imbalance is most likely?

Accepted Answer

Metabolic acidosis

Question 19

Which equation best represents the relationship between energy intake ($$EI$$), energy expenditure ($$EE$$), and change in body weight ($$\Delta BW$$)?

Accepted Answer

$$\Delta BW = EI - EE$$

Question 20
