Where does the lymphatic system drain?
Lymph is interstitial fluid that drains from the blood vessels and goes into the interstital space. Lymph retruns to the blood stream via the lymphatic vessels that drain into the subclavian vein.
What is the role of thoracic duct?
The main function of the thoracic duct is to allow lymph transport that is caused by breathing. It also prevents blood from flowing into the ducts.
What does the thoracic duct do?
Like the arteries and veins which carry blood, the thoracic duct is a vessel belonging to the lymphatic system which transports the lymph from the body and drains in the veins of the neck on the left side
Is there a connection between lymph and blood?
Yes! Lymph is an important part of the circulatory system. It helps maintain the fluid balance in blood by carrying fluid from extracellular environments into the blood stream (such as water, proteins, and other substances). Lymph also plays a primary role in one's immunity because it is rich in white blood cells (lymph nodes are also the sight for lymphocyte production, which remove microorganisms and other foreign materials by utilization of phagocytosis). The two main ducts that drain lymph into the bloodstream include: 1.) right lymphatic duct- drains lymph from upper right portion of body into the right subclavian vein. 2.) thoracic duct- drains lymph from the rest of the body to the left subclavian vein (just before it becomes the superior vena cava).
What is reactive lymph node?
It's a lymph node that drains an inflamed area. The source of the inflammation can be bacterial-viral infection, immunological disease, or malignancy.
What is the excess interstitial fluid drains from body tissues?
Lymph.
Why is it important that lymph vessels are spread throughout body?
lymph vessels are like blood vessels and they carry fluid similar in composition to blood plasma (only that they carry clear fluid containing less protein than blood plasma and numerous white blood cells which help to fight infection, especially lymphocytes), the body tissues are bathed in lymph from the blood , then the lymph vessels drain the lymph away just like the vein drains deoxygenated blood from body back to the heart, in a situation whereby the drainage of lymph by the lymph vessels is interupted, there is accumulation of fluid in that part of the body causing edema( excessive accumulation of fluid in the body) so the lymph vessels are important for drainage of lymph throughout the body and due to this they are able to carry antibodies(foreign micro organisms in the body) to the lymph node to be destroyed. all the lymph that is collected goes to the thoracic duct and right lymphatic duct which then empty back into the blood.

Most of the lymph of the body drains into this large duct?
Thoracic duct.
Does the lymph node system vessels form a continuous loop through body?
No, the system drains into the blood circulatory system via the left and right lymphatic ducts.
What do the the thoracic do?
The thoracic duct serves as a duct which lymph drains into which then drains into the venous system before returning to the heart to be cleansed and recirculated.
What is the Difference between blood and lymph?
lymph caries digested and absorbed fat from intestine and drains excess fluid from extra cellular space back into blood. Lymph is basically blood plasma without the blood cells, the fluid that is forced out of capillaries to clean and nourish cells. The part of it that does not return to the blood vessels is picked up by lymph vessels and eventually returned to the blood.
