What function do the skeletal muscles play in the lymphatic system?
Skeletal muscles pump lymph through the lymph vessels. The valves prevent back flow
What is the function of lymph nodes?
testing lymph for foreign invaders, adding lymphocytes to the blood, filtering lymph with macrophages
What are the three functions of the spleen?
1. Cleanse the blood of foreign invaders, 2. To dispose of worn out erythrocytes, 3, to be a reservoir of oxygen rich blood.
Where does the lymphatic system deposit the lymph back into the blood?
subclavian vein
What is the difference between interstitial fluid and blood plasma?
Plasma has proteins that are not able to diffuse out of the capillaries
Identify a and b, and tell their function
a. lymph valve – prevents back flow of lymph,b.afferent lymph vessels-vessels that carry lymph to a lymph node
Identify d and e, and give their functions.
d. lymph nodule – lymph tissue arranged in compact spherical structures without a capsule, e. capsule – dense connective tissue encapsulating the lymph node
Identify f and g, and give their function.
f. trabeculae – structure, support, g. efferent lymph vessel - Lymph vessels that carry lymph away from a lymph node
Identify h and c, and give their function.
h. reticular fibers- a net of connective tissue. support, c. germinal center – mitosis of lymphocytes can take place in response to a foreign invader.
What are viruses?
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism.
What are Peyer's patches
Peyer's patches are groupings of lymphoid follicles in the mucus membrane that lines your small intestine.
What is the difference between Plasma B cells and memory B cells?
Plasma B cells produce and release antibodies, whereas Memory B cells remember the infection so they can respond quicker the next time
What is passive immunity? How long does it last? give and example
antibodies you receive from someone else. not long: an infant gets antibodies through placenta and breast milk, Rh-mom receives Rh+antibodies in a shot,rhogam
What is edema?
A build up of excess interstitial fluid in the tissues, which leads to swelling
