True
False
This type of immunity refers to the body's defenses that involve specific recognition of a microbe once the innate immunity has been breached.
(a)
The fluid that circulates through the lymphatic system is called?

primary lymphatic organs
secondary lymphatic organs
These are the sites where most immune responses occur.
primary lymphatic organs
secondary lymphatic organs
LYMPHATIC ORGANS/TISSUES
What is the name of this organ?
(a)
LYMPHATIC ORGANS/TISSUES

spleen
red bone marrow
appendix
thymus
no correct answer
LYMPHATIC ORGANS/TISSUES
Which of the following are the functions of the spleen?
stores a small volume of blood

LYMPHATIC ORGANS/TISSUES
(a) ensure that lymph flows in one direction only.
LYMPHATIC ORGANS/TISSUES
The __________ of the spleen consists mostly of lymphocytes and macrophages.
white pulp
red pulp
LYMPHATIC ORGANS/TISSUES
The __________ of the spleen consists of blood-filled venous sinuses and splenic cords.
white pulp

The spleen produces RBCs during fetal life.
True
False
LYMPHATIC ORGANS/TISSUES
Aggregated lymphatic follicles, which are found in the ileum of the small intestine, are also called (a) .
Our mucous membranes secrete (a) , which lubricates and moistens the surface of body cavities.

True
False
The (a) of the eyes produce tears when exposed to irritants.
