The orgin on lymph is this: the cardiovascular system pumps blood through its system but it cannot return all the fluid from the body cells. The lymph system picks up 60%of the fluid dropped off at the cellular level, at this point we are talking about interstial fluid, the IF picks up plasma and becomes tissue fluid. The tissue fluid is then picked up my lymph capillaries, the tissue fluid is now called lymph.

How does lymph move through the lymph vessels without a pump?

Lymph is moved through the lymph vessels by surrounding muscles contracting and relaxing, which creates pressure changes that help propel the lymph forward. Additionally, one-way valves within the lymph vessels prevent the backflow of lymph, helping to maintain the flow.


What is the difference between cephalic lymph nodes and pectoral lymph nodes?

The pectoral lymph nodes are also known as the anterior group and can be found just inferior to the pectoralis minor muscle, the cephalic nodes are also known as deltopectoral lymph nodes and they receive lymph from the superficial vessels only


Are there lymph nodes in the jawline?

Yes, there are lymph nodes located along the jawline. These lymph nodes play a role in filtering lymph fluid and immune response in the head and neck region. Swelling or tenderness in these lymph nodes can sometimes be an indication of infection or inflammation in the surrounding areas.


Can lymph nodes leak fluid?

Lymph nodes can produce and contain lymph fluid, but they do not typically leak fluid. If a lymph node is damaged or infected, it may become enlarged or tender, but leakage of lymphatic fluid from a lymph node is not a common occurrence.


What happens inside a lymph node?

Lymph nodes filter lymph fluid to remove foreign particles, such as bacteria or viruses, and also produce immune cells to help fight infections. They contain a network of lymphocytes and macrophages that detect and respond to pathogens to prevent them from spreading throughout the body.
