Answer 1

FYI

No discussion of the circulatory system would be complete without emphasizing that it is composed of the blood and lymph vascular systems. Unlike the blood vascular system, the lymphatic circulation has no heart of its own. Instead, lymph - a viscous, creamy fluid devoid of red blood cells - picks up materials from the tissue fluids via blind-ended, thin-walled lymph capillaries. These lymphatic capillaries flow into larger vessels that pass lymph through lymph nodes. Lymph, which is picked up from the tissue spaces, is delivered into the blood vascular system at the subclavian vein; close to the neck, a large lymphatic vessel enters the wall of the subclavian vein and empties its contents into the lumen of that blood vessel. As a result, the blood and lymph vascular systems, although made up of a separate system of tubes, eventually connect with one another.
