Ngoc Nguyen Period: 5
Lymphatic/ Immune system
:star:
Immune System
: Functions as the body defense against infection Pathogens
Keeps pathogens out and attacks those that do enter the body.
Lymphatic System
: a network of vessels that assist in the circulation of body fluids
Collect and carry away one way excess fluid
Lacteal transport fats to the circulatory system
Lymphoid Organs
Spleen
upper left abdominal cavity and largest lymphatic organ.
It contain blood instead of lymph
White pulp and red pulp
Filters the blood and removes danged blood cells and bacteria.
Tonsils
Lymphoid tissue andound the opening
Pharyngeal tonsil( also known as adnoid
Subject to chronic infection: tonsils ma impair breathing
Lymph Nodes
Function: remove bacteria and cellular debris, and lymphphocyte production theses cells faction in immune surveillance
Contain lymphocytes and macrophages
Located: along lymphatic vessels
Contain both lymphocytes and macrophages which clean the lymph as it flows through the node.
Thymus
Location: behind the sternum
contain lymphocytes
The thymus secretes hormones called thymosins
Antigens
Can be entire pathogen or a part of it
Anything that can cause an immune response
antigen are generally larger and more complex molecules
Lymphocytes
T Lymphocyte (T cells)
Cause: direct destruction of virus invaded cell and mutant cells
Involved in cell mediated immunity
B Lymphocyte (B cells)
In humoral or antibody mediated immunity
Made and develops in the bone marrow& thymus
Cause: secrete antibodies that indirectly
Immunity
2. Artificially acquired active immunity
: use through vaccines, without the person becoming ill from the disease.
3. Artificially acquired passive immunity
: the injection of gamma globulin containing antibodies (antiserum) and short-lived.
1. Naturally acquired active immunity
: occurs after exposure to the antigen itself.
4. Naturally acquired passive immunity:
As antibodies are passed from mother to fetus and is short-lived.
HIV H-Human I-immunodeficiency V-virus
HIV is a virus is an infection
Transmitted to unprotected sexual contact
Sharing underutilized needles or syringe
During pregnancy or birth and through breastfeeding
Blood transfusions
AIDS Or Acquired Immune
Deficiency Syndrome, can take many year to develop
The kills or impairs more and more cells in the immune and the body
Loses the ability to fight off common infection
