MICROANATOMY

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. The main roles of the lymphatic system include: managing the fluid levels in the body.

Detailed explanation-3: -The body’s lymphatic system helps to protect itself from invaders that cause illness. The lymphatic system can release white blood cells (lymphocytes) that destroy those foreign substances. This system also produces other immune cells (including monocytes and plasma cells) and destroys abnormal cells (cancer cells).

Detailed explanation-4: -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).

Detailed explanation-5: -There are three primary functions of the lymphatic system: first is the maintenance of fluid balance, second is the facilitation of the absorption of dietary fats from the gastrointestinal tract to the bloodstream for metabolism or storage, and third is the enhancement and facilitation of the immune system.
