What take place in lymph lodes?

In your blood from your arteries flows into your capillaries. Most of that returns to your heart through your heart. Some returns through the lymph system. The lymph system carries lymph or a fraction of your blood through your system checking for pathogens. It brings them to the lymph nodes. The nodes check the lymph for infection. If the lymph nodes find infection, they start producing antibodies against the infection and inform the rest of the body that infection exist. They sometimes become inflamed when they collect bacteria faster than they can destroy it. Still, they stop it rather than let it go on through the body. They let the lymph go from the lymph nodes back to the veins and back to the heart to recirculate.

Is the plasma membrane the same as intercellular fluid?

There are many differences that can be found between blood and lymph fluid. The cells that are present in blood include erythrocytes, leucocytes, and plates. In lymph fluid the only cells present are lymphocytes. Blood contains hormones and plasma proteins making blood rich in proteins. Lymph fluid has very few proteins present. Blood contains more glucose, amino acids, and oxygen than lymph fluid. However, lymph fluid has more carbon dioxide than blood.


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.
