Lymphatic system

1. Bean shape lymphatic organs found along lymphatic vessels are called...

a. lymph nodes
b. medullary cords
c. germinal centers
d. cistema chili

a) lymph nodes. http://www.sirinet.net/~jgjohnso/lymphatic.html

2. In innate immunity

a. each exposure is very specific
b. previous exposure are remembered
c. each exposure elicits approximately the same type of response
d. each exposure increases the strength of the immune response

c) Innate immunity is a very broad line of defense that elicits nearly the same response upon each exposure. There is no memory unlike in adaptive immunity or the ability to learn after each exposure. Some examples of innate immune barriers are things as simple as skin and mucus. There are also certain cell types that respond to general viral infections. For more information see http://en.wikipedia.org/wiki/Immune_system

3. Transplanted tissues and organs are..
a. self antigens
b. auto antigens
c. foreign antigens
d. antibodies

c) Foreign antigens. Transplanted tissues and organs come from a different source than the host that they are being transplanted into. Therefore they would have cell-surface proteins that are specific to their source and not the host. The host would recognize them as being forward and create antibodies to destroy them. This is why transplant patients are given immune suppressants prior to transplantation. Antigens are the proteins on the cell surface recognized by antibodies. Self-antigens would be the same as the hosts. Auto antigens are self antigens that are recognized by the host and destroyed even though they are their own.

4. ----------- are part of cell mediated immunity while --------------- are part of antibody mediated immunity.

a. B cells / NK cells
b. T cells / B cells
c. Antibodies / antigens
d. Macrophages/ antibodies

d) Macrophages, NK cells and T cells are apart of the cell-mediated immunity. The antibody-meditated immunity requires B cells (these cells produce antibodies), antigens and antibodies. See ...
