Which thin-walled vessels are responsible for carrying lymph from tissues?

Lymphatic vessels are specialized thin-walled structures designed to transport lymph, a clear fluid that contains white blood cells, proteins, and other substances, from the tissues back to the circulatory system. These vessels play a crucial role in the immune system by facilitating the movement of lymph, thereby helping to filter out pathogens and other foreign materials. They are part of the lymphatic system, which is vital for maintaining fluid balance and supporting the immune response.

While arteries and veins are also types of blood vessels, they primarily carry blood rather than lymph. Arteries transport oxygen-rich blood away from the heart, and veins carry deoxygenated blood back to the heart. Capillaries, on the other hand, are small blood vessels where the exchange of oxygen, nutrients, and waste occurs between blood and tissues, but they do not transport lymph. Thus, lymphatic vessels are the correct choice as they are specifically designed for carrying lymph from tissues through a network that leads to lymph nodes and eventually back into the bloodstream.
