Question

true or false Because lymph vessels are very low-pressure conduits, movements of adjacent tissues are important in propelling lymph through the lymphatics.

Answer 1

The statement is true; lymph vessels are low-pressure and rely on movements of adjacent tissues such as skeletal muscle contractions and body movements to propel lymph through the lymphatic system.

Step-by-step explanation:

The statement 'Because lymph vessels are very low-pressure conduits, movements of adjacent tissues are important in propelling lymph through the lymphatics' is true. Unlike blood which is pumped through the body by the heart, lymph is moved through the lymphatic system primarily by the contraction of skeletal muscles, the movements of the body, such as breathing, and the contractions of the lymphatic vessels themselves. These vessels contain one-way valves that prevent the lymph from flowing backward, thus ensuring it moves in one direction towards the heart.

The lymphatic system does not form a full circulating system and is not pressurized by the heart. Instead, it relies on the movement of the body to force the lymph through the lymphatic vessels. Lymph is transported from lymphatic capillaries, through larger vessels, and eventually drains back into the bloodstream via lymphatic ducts located at the junction of the jugular and subclavian veins in the neck.

Answer 2

True

Step-by-step explanation:

The lymphatic system is a complex network of vessels and small structures called lymph nodes that carry lymph fluid, the lymph, from the tissues back to the circulatory system.

Lymph travels through the lymphatic system due to weak muscle contractions, pulsation of nearby arteries, and movement of the extremities. Lymph depends exclusively on the action of external agents to be able to circulate. The lymph moves slowly and under low pressure mainly due to the compression caused by the movements of the skeletal muscles that presses the fluid through it, in addition the circulation occurs in one direction: towards the heart.
