Worked practice questions

How does lymph move in humans without a central lymph pump?

  1. Osmosis in nearby arteries
  2. Muscle contractions and valves
  3. Cilia moving blood plasma
  4. A four-chambered heart pump
Show answer and solution

Correct answer: B. Muscle contractions and valves

Skeletal-muscle compression and valves help move lymph.

Which lymphatic function helps defend the body from infection?

  1. Lymph makes platelets in the heart
  2. Lymph blocks all tissue fluid flow
  3. Lymph converts oxygen into glucose
  4. Lymph nodes participate in immune defense
Show answer and solution

Correct answer: D. Lymph nodes participate in immune defense

Lymph nodes are sites where immune cells encounter antigens and bacteria.

A stroke volume of 70 mL at 72 beats/min gives cardiac output near:

  1. 5.04 L/min
  2. 0.97 L/min
  3. 50.4 L/min
  4. 142 L/min
Show answer and solution

Correct answer: A. 5.04 L/min

Cardiac output is stroke volume times heart rate: 70 × 72 = 5040 mL/min, or 5.04 L/min.
