Worked practice questions

Interstitial fluid takes on which name once it has entered the lymphatic system?

  1. Lymph
  2. Plasma
  3. Serum
  4. Mucus
Show answer and solution

Correct answer: A. Lymph

1. Capillary filtration pushes plasma out of the blood vessels into the spaces between the cells of the tissues. 2. Once that filtrate is out of the bloodstream and in the tissue spaces it is called interstitial fluid. 3. Once the same fluid drains into a lymphatic vessel it is called lymph. 4. Plasma names the fluid while it is still inside the blood vessels, so it is the wrong label here. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 21 "The Lymphatic and Immune System", section 21.1 Anatomy of the Lymphatic and Immune Systems_

What keeps lymph moving through the lymphatic vessels toward the heart?

  1. Pumping by the left ventricle
  2. Suction from the thoracic duct
  3. Body movement and breathing
  4. Beating of vessel cilia
Show answer and solution

Correct answer: C. Body movement and breathing

1. A major difference between the lymphatic and cardiovascular systems is that lymph is not actively pumped by the heart. 2. It is forced through the vessels by the movements of the body, the contraction of skeletal muscles and breathing. 3. One-way semi-lunar valves in the lymphatic vessels stop backflow, so all of that squeezing moves lymph toward the heart. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 21 "The Lymphatic and Immune System", section 21.1 Anatomy of the Lymphatic and Immune Systems_

Cancer cells block a patient's lymphatic drainage and protein-rich fluid builds up in the tissue spaces. What is this accumulation called?

  1. Anaphylaxis
  2. Inflammation
  3. Seroconversion
  4. Lymphedema
Show answer and solution

Correct answer: D. Lymphedema

1. The lymphatic system exists to drain the excess fluid that capillary filtration leaves behind in the tissues. 2. When it is blocked by cancer cells or destroyed by injury, protein-rich interstitial fluid backs up in the tissue spaces. 3. That inappropriate accumulation of fluid is called lymphedema and may lead to serious medical consequences. 4. Inflammation also swells a tissue, but it is driven by mediators such as histamine rather than by a blocked drainage route. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 21 "The Lymphatic and Immune System", section 21.1 Anatomy of the Lymphatic and Immune Systems_
