Question Answer
What does lymph transport involve? Lymphatic system lacks an organ that acts as a pump. Milking action of skeletal muscles, Movement of chest during respiration creates variations in pressure, Rhythmic contractions of lymphatic smooth muscle (Vessel walls contract to push lymph along.)
What is the right lymphatic duct and where does it drain from? The right lymphatic duct, drains lymph from the right side of the head, the right arm, and the thorax. Lymph is formed from blood and returns to blood.
What are the parts of the lymphatic system?

-lymphatic vessels, lymph, and nodes(organs include lymph nodes, tonsils, thymus gland, spleen, malt)Network of lymphatic vessels, Lymphoid tissues and organs throughout the body
What are lymphatic capillaries? are tiny, thin-walled vessels located in the spaces btween cells (excepts in the nervous system and non-vascular tissue) and serve to drain and process extra-cellular ffluid
What is lymph made of?

Is a clear to white liquid ( blood>interstitial fluid>lymphocytes, the cell that attacks bacteria in the blood. fluid from the intestines called chyle, which contains protiens and fats
What is the function of the lymphoid tissue? lymphoid tissue is an important component of the immune system mainly because it houses and provides a proliferation site for lymphocytes and furnishes an ideal surveillance vantage point for lyphocytes and macrophages
What is the function of the lymph nodes?

Returns interstitial fluid to the blood, Absorbs fats and fat-soluble vitamins, Helps the body defend itself against infection. Nodes are made of lymphocytes and macrophages.
How does lymph flow?

-Lymph flows into the node via the afferent lymphatic vessel and is drained by the efferent lymphatic vessel. In this way, it moves from node to node and ultimately to one of the large lymphatic ducts.
What is the efferent and afferent lymphatic vessels?

-lymph enters the convex side of a lymph node through a number of afferent lymphatic vessels, and Exits the nodes at efferent vessels
What are B cells?

The B cells engage in antibody-mediated immunity. The activated B cells secrete antibodies, which engage in an antigen-antibody reaction within the pathogen. The resulting agglutination or clumping destroys the pathogen.
what are T cells The T cells engage in cell-mediated immunity; they attack pathogens directly by punching holes in the cell membrane and secreting lymphokines. The lymphokines enhance phagocytosis.
Who are the defenders for the innate immune system? [NONSPECIFIC IMMUNITY]first line:mechanical or chemical barriers, reflexes. Second line:phagocytosis, inflammation,fever, protective protiens, natural killer cells [SPECIFIC IMMUNITY]. Third line: B and T lymphocytes(cells)
Define fever. An abnormally high body temperature, is a systemic response to invading microorganisms
Define immune competence. each lymphocyte must become able to recognize its one specific antigen by binding to it.
What is an autoimmune disease and list some of these diseases?

Autoimmune disease is your immune system loses it ability to distinguish self from foreign antigens. Some examples of autoimmune disease include thyroiditis, myasthenia gravis, rheumatic fever, rheumatoid arthritis, and some forms of diabetes mellitus.
What is the function of antibodies? also known as immunoglobin, is a large y shaped protein produces by b cells and used by the immune system to indetify and neutralize foreign abjects such as bacteria and viruses
Define immunodeficiency. -is congenital or acquired condition that impairs the production or function of immune cells or certain molecules, such as complement or antibodies.
What is AIDS? acquired immune deficiency syndrome which cripples the immune system by interfering witht e activity of helper t cells. Virus transmitted in body secretions-especially blood semen and vaginal secretions.
