The lymphatic system is one of the most complex in the human body, reaching all points from the head down to the toes. Understanding the lymphatic system PPT means using a proper diagram to allow for the right visualization of the process. That is where a good lymphatic system PowerPoint diagram can really help in presentations.
What is the Lymphatic System?
This is part of the vascular system that is made from a network of lymphatic vessels which contain the lymph fluid to the heart. First fully described in the 17th century, the lymphatic system is not a closed one such as the circulatory system, but rather the lymphatic system provides another route to return the blood to its normal levels in the body.
Another function of the lymphatic system is how it supports the immune system in the body. Containing lymphocytes, the system also carries the debris of cells and waste products along with proteins and bacteria which helps to bolster the immune system.
Structure of the Lymphatic System
The network consists if three different systems that affect different areas of the body. The entire system works together to assist the body with important functions.
Primary: This consists of the bone marrow and thymus which are the primary organs involved in lymphoid production. The bone marrow creates the T cells and B cells which travel to the circulatory system. The T cells are directed to the thymus while the B cells search for pathogens. It should be noted that most T cells inside the primary lymphatic system are facing a pre-programmed death.
Secondary: This consists of the lymph nodes and spleen which contribute to the immune response in the body. This is because antigens are present in the peripheral lymphoid organs which help to address infection or illness in the body.
Tertiary: This tissue contains a few lymphocytes and acts with the immune system when invaded by antigens that create inflammation. By importing lymphocytes from lymph and blood, this system gets involved as part of the immune system to counter the threat of infection.
Major Lymphoid Tissues
In addition to the network, there are organs and tissues that play a role as well. The lymph nodes are the ones most associated with the lymphatic system, but there are two major tissues or organs that are also part of the system as well.
Spleen: The spleen produces immune cells to combat antigens, removes old or decayed blood cells, and produces blood cells during the fetal stage of life. It also synthesizes antibodies which helps fight infection and while it can be removed without doing major damage to the body, it also means that certain infections become tougher for the body to remove.
Thymus: This is part of the primary system, providing for the maturation of T cells. It also plays a role in the adaptive immune system. Without the thymus, the immune system would be under severe strain when responding to infection.
Ultimately, understanding the flow and reach of the lymphatic system starts with using a good diagram found in a proper lymphatic system PowerPoint. This provides viewers a way to visualize the process and understand the lymphatic system PPT by seeing just how it works.
