Question

which are functions of the lymphatic system? select all that apply.
a return excess tissue fluid to the bloodstream
b absorb fat - soluble nutrients in the digestive tract
c fight infections
d produce blood cells
e transport nutrients to the liver for processing

Explanation:

• Option A: The lymphatic system collects excess tissue fluid (lymph) and returns it to the bloodstream, maintaining fluid balance.
• Option B: Lymphatic vessels in the small intestine (lacteals) absorb fat - soluble nutrients (like fats and fat - soluble vitamins) from the digestive tract.
• Option C: The lymphatic system contains lymphoid tissues (e.g., lymph nodes, spleen) that house immune cells (like lymphocytes) which help fight infections.
• Option D: Blood cells are produced in the bone marrow, not the lymphatic system.
• Option E: The lymphatic system does not transport nutrients to the liver for processing; the circulatory system and other digestive - related pathways are involved in nutrient transport to the liver.

Answer:

A. Return excess tissue fluid to the bloodstream, B. Absorb fat - soluble nutrients in the digestive tract, C. Fight infections
