IMMUNOLOGY

Detailed explanation-1: -Breslin et al aptly described the analogy best: “[while arteries and] veins [function] like a super highway, lymphatics are slow local roads eventually leading to the heart.”

Detailed explanation-2: -The lymphatic system is a network of delicate tubes throughout the body. It drains fluid (called lymph) that has leaked from the blood vessels into the tissues and empties it back into the bloodstream via the lymph nodes.

Detailed explanation-3: -One of the lymphatic system’s major jobs is to collect extra lymph fluid from body tissues and return it to the blood. This is important because water, proteins, and other substances are always leaking out of tiny blood capillaries into the surrounding body tissues.

Detailed explanation-4: -Which of the following best describes the lymphatic capillaries? They have large pores and follow venous pathways.

Detailed explanation-5: -Correct answer: The lymphatic system has a variety of functions in the body. It collects excess interstitial fluid and returns it to the blood (cardiovascular system), it has lymph nodes that screen the lymphatic fluid for pathogens (immune system), and it reroutes fat digestates to the neck veins (digestive system).
