Study Guide-Immune System
Lymphatic System
major components
lymph
a colorless fluid containing white blood cells, which bathes the tissues and drains through the lymphatic system into the bloodstream
lymphatic vessels
thin-walled vessels. The vessels drain into the right and left subclavian veins, respectively.
lymphatic organs
include the thymus, spleen, bone marrow
Types of Leukocytes
T and B cell rolls
b cell involve in humeral immunity
t cells involved in cell modefied immunity
both recognize specific "non-santi" antigens
memorial cell
variation of T and B lymphocytes, they live for years ready to attack a particular pathogen
aganutal
lymphocytes (20-30%)
Vaccination
types
allow body to respond quickly to future infection by pathogens
heard immunity>enough people vaccinated so the pathogen cant spread in a population
Immune disease disorders
HIV
geriatric
Most common SCID
infects and destroys T cell
common cause if immunodeficiency. HIV is transmitted through direct contact of mucous membrane
aging
immune system less effective as we age
lymphatic system dysfunction
lymph nodes and lymph's vessels that drain fluid from our body tissue may not be working properly
autoimmune
immune system attacks your own body causing significant damage
Immune System Response
Barrier
Barrier defenses are part of the body’s most basic defense mechanisms. They are also associated with the external surfaces of the body.
primary barrier to the entrance of microorganisms into the body is the skin.
Defenses
Epidermal surface,Sweat glands, sebaceous glands,Salivary glands
Natural Acquired Immunity
being exposed to a live pathogen and developing a primary immune response
INNATE
combined action of phagocytes and granular white blood cells
white blood cells eat pathogens
