Question 4

A patient presents with swelling in the lower limbs due to blocked lymphatic vessels. What is the most likely physiological explanation for this edema?

Accepted Answer

Question 10

Which of the following is a consequence of impaired lymphatic function?

Accepted Answer

Accumulation of interstitial fluid leading to edema

Question 11

Which of the following best explains why lymphatic capillaries are described as 'blind-ended'?

Accepted Answer

They begin as closed tubes in the tissue spaces

Question 12

Which of the following is TRUE regarding the movement of water and electrolytes between fluid compartments?

Accepted Answer

Question 13

Which lymphatic structure is most likely to enlarge during an active infection?

Accepted Answer

Lymph nodes

Question 14

Which of the following best describes the flow of lymph through the lymphatic system?

Accepted Answer

Lymph flows from capillaries to trunks to ducts

Question 15

A patient has a genetic defect affecting the formation of lymphatic vessels. Which of the following symptoms would most likely be observed?

Accepted Answer

Edema due to accumulation of interstitial fluid

Question 16

Which of the following is the correct order of lymph flow from tissues back to the bloodstream?
