Lymphatic System Outline:
The portion of blood plasma that escapes is called interstitial or extracellular fluid , and it contains oxygen , glucose , amino acids , and other nutrients needed by tissue cells. Blood vessels, lymphatic vessels, and nerves embryological development In prenatal development: The cleansed lymph continues to travel in only one direction, which is upward toward the neck. While many associate yoga with new age mysticism or the latest fad at the gym, yoga is actually an ancient practice that connects the mind, body, and spirit through body poses, controlled breathing, and meditation. This fluid delivers nutrients, oxygen, and hormones to the cells. Unlike blood, which flows throughout the body in a continue loop, lymph flows in only one direction — upward toward the neck.
Diseases and disorders of the lymphatic system
It is the role of these nodes to filter the lymph before it can be returned to the circulatory system. Although these nodes can increase or decrease in size throughout life, any nodes that has been damaged or destroyed, does not regenerate.
Lymphatic system drainage is organized into two separate, and very unequal drainage areas. The right drainage area clears the right arm and chest. This information does not replace the advice of a qualified health care professional.

The lymphatic system also removes excess fluid, and waste products from the interstitial spaces between the cells.
Unlike blood, which flows throughout the body in a continue loop, lymph flows in only one direction within its own system. After plasma has delivered its nutrients and removed debris, it leaves the cells.
The cleansed lymph continues to travel in only one direction, which is upward toward the neck. At the base of the neck, the cleansed lymph flows into the subclavian veins on either side of the neck. This fluid delivers nutrients, oxygen, and hormones to the cells.
As this fluid leaves the cells, it takes with it cellular waste products and protein cells. Here it enters the venous circulation as plasma and continues in the circulatory system. Deeper within the body the lymphatic vessels become progressively larger and are located near major blood veins. Smooth muscles in the walls of the lymphatic vessels cause the angions to contract sequentially to aid the flow of lymph upward toward the thoracic region. Because of their shape, these vessels are previously referred to as a string of pearls.
Afferent lymphatic vessels carry unfiltered lymph into the node. Here waste products, and some of the fluid, are filtered out. In another section of the node, lymphocytes, which are specialized white blood cells, kill any pathogens that may be present. Is a group of approximately 20 proteins found in plasma responsible for inflammation, phagocytosis, and cell lysis: Results from the natural exposure to a disease that prompted the body to produce antibodies: Active Natural Immunity B.

Basophils, which are derived from red bone marrow, are motile white blood cells that can leave the blood and enter infected tissues. Mast cells, which are also derived from red bone marrow, are nonmotile cells in connective tissue, especially near capillaries. Eosinophils are produced in red bone marrow, enter the blood, and within a few minutes enter tissues.
In innate immunity, the immunity to a substance is produced only after exposure to that substance and each time the body is exposed to a particular substance, the response is the same. For example, each time a bacterial cell is introduced into the body, it is phagocytized with the same speed and efficiency. In adaptive immunity, the response to them improves each time the foreign substance is encountered.
The response during the second exposure is faster and stronger than the response to the first exposure because the immune system exhibits memory for the bacteria from the first exposure.
Innate immunity is accomplished by mechanical mechanisms, chemical mediators, cells, and the inflammatory response. Is a group of approximately 20 proteins found in plasma responsible for inflammation, phagocytosis, and cell lysis:.
Complement is a group of approximately 20 proteins found in plasma. Interferons are proteins that protect the body against viral infections. Prostaglandins are potent lipid molecules that affect key aspects of immunity. B cells are type of lymphocytes which give rise to cells that produce proteins called antibodies Option B: T cells are released from the thymus.
B cells mature in the bone marrow. T cells are responsible for cell-mediated immunity. Cytotoxic T cells produce the effects of cell-mediated immunity. Antibodies are called gamma globulins because they are found mostly in the gamma globulin part of plasma. They are also called immunoglobulins Ig. The rest of the antibody is the constant region, which can activate complement or attach to macrophages. Antibodies make up a large portion of the proteins in plasma.
Cytotoxic T cells are responsible for cell mediated immunity. B cells are responsible for antibody mediated immunity. Memory B cells are B cells responsible for secondary response. Helper T cell is a special type of T cell that helps the activity of other immune cells by releasing T cell cytokines.
The antibody that is rich in saliva, tears, colostrums:. IgA is the main immunoglobulin found in mucous secretions, including tears, saliva, sweat, colostrum and secretions from the genitourinary tract, gastrointestinal tract, prostate and respiratory epithelium.
