How does the lymphatic system work step by step?

What is the lymphatic system?

  1. it acts as a one-way drainage system – this means it moves fluid from body tissues into the blood circulation.
  2. it contains white blood cells called lymphocytes, which fight infection.
  3. it gets rid of any waste that cells make.

Where does the lymph transport system start and in which vessels?

One of the major lymphatic vessels is the thoracic duct, which begins near the lower part of the spine and collects lymph from the pelvis, abdomen, and lower chest. The thoracic duct runs up through the chest and empties into the blood through a large vein near the left side of the neck.

How is the lymphatic system connected to the circulatory system?

Lymphatic vessels connect to the subclavian veins, which are part of the blood circulatory system and connect to the heart. Their key function is to transport excessive tissue fluid from interstitial spaces throughout the body back to the blood stream.

Where do the lymphatic ducts empty into the circulatory system?

The lymphatic vessels drain into collecting ducts, which empty their contents into the two subclavian veins, located under the collarbones. These veins join to form the superior vena cava, the large vein that drains blood from the upper body into the heart.

What is a function of the lymph vascular system?

Lymphatic vessels: Lymphatic vessels are the network of capillaries (microvessels) and a large network of tubes located throughout your body that transport lymph away from tissues. Lymphatic vessels collect and filter lymph (at the nodes) as it continues to move toward larger vessels called collecting ducts.

Are lymph nodes part of the vascular system?

A, In overview, the unidirectional lymphatic vascular system consists of (1) lymphatic capillaries, (2) collecting lymphatic vessels, (3) lymph nodes, and (4) the thoracic duct and right lymphatic trunk.

What is lymph circulation?

Lymph is fluid that drains from the extracellular space of tissues. Lymph vessels return this fluid to the circulating blood. It is a one “circuit system” until the two interconnected circulatory system comprised by the arteries and veins.

Is the lymphatic system part of the circulatory system?

The lymphatic system is a subsystem of the circulatory system in the vertebrate body that consists of a complex network of vessels, tissues, and organs. The lymphatic system removes this fluid and these materials from tissues, returning them via the lymphatic vessels to the bloodstream.
