(b) Filter lymph

(c) Transport leaked plasma proteins and fluids to the cardiovascular system

(d) Are represented by vessels that resemble arteries, capillaries, and veins.

Answer to Problem 1RQ

Solution:

(c) Transport leaked plasma proteins and fluids to the cardiovascular system

Explanation of Solution

The lymphatic vessels are thin-walled structures that transport lymph, the fluid circulating in the lymphatic system. Majority of them carry B and T lymphocytes (white blood cells). The primary role of lymphatic vessels is to carry and pick up the fluid that leaks into the tissues from the bloodstream and return it back to the circulatory system.
