Multiple Choice

Which of the following best describes the arrangement of lymphatic vessels?

a system that carries lymph through lymphatic arteries, lymphatic capillaries, and lymphatic veins

a system that collects fluid from arteries and veins and takes it into lymphatic arteries to be pumped back to the blood circulation

a one-way system of vessels beginning with blind-ended lymphatic capillaries

a system that pumps lymph through lymphatic ventricles to the lymphatic capillaries and through lymph veins back to the atria

a system of large vessels designed to fill quickly with lymph as the heart pushes blood through the coronary sinus

Verified step by step guidance

Understand the function of the lymphatic system: The lymphatic system is responsible for the transport of lymph, a fluid containing infection-fighting white blood cells, throughout the body.

Identify the structure of lymphatic vessels: Lymphatic vessels are a network of tubes that carry lymph away from tissues and towards the heart.

Recognize the starting point of lymphatic vessels: Lymphatic vessels begin as blind-ended lymphatic capillaries, which are closed at one end and collect excess fluid from tissues.

Follow the flow of lymph: Lymph flows from lymphatic capillaries into larger lymphatic vessels, eventually reaching lymph nodes where it is filtered.

Conclude with the one-way nature: The lymphatic system is a one-way system, meaning lymph flows in one direction, from the tissues back towards the heart, without a central pump like the heart in the circulatory system.
