QUESTIONS AND ANSWERS SURE A+
✔✔At any given moment, where can blood be found in the body? - ✔✔Veins
✔✔major arteries of the body - ✔✔temporal, carotid, brachial, ulnar, radial, femoral,
popliteal, dorsalis pedis, posterior tibial
✔✔major veins of the body - ✔✔Superior and inferior vena cava, right and left external
and internal jugular and subclavian v, right and left brachiocephalic v, hepatic v, splenic
v, right and left common iliac v, external and internal iliac v, femoral v, great saphenous
v, small saphenous v
✔✔What is arteriosclerosis? - ✔✔the thickening and hardening of the walls of the
arteries
✔✔How does aging affect the cardiovascular system? - ✔✔Cholesterol deposition
happens in the blood vessels, the heart enlarges, cardiac muscle cells die, there is an
increase in fibrous connective tissue, adipose tissue and blood pressure and a
decrease in resting heart rate.
, ✔✔What is the function of lymph? - ✔✔To absorb dietary fats, deliver fats and excess
fluids to the bloodstream, collect excess interstitial fluids, and deliver foreign particles to
the lymph nodes.
✔✔Describe a lymphatic vessel - ✔✔Fine, thin-walled, transparent valved channels
distributed through most tissues. They have 3 walls: intima, media, and adventitia.
✔✔Describe the pathway of lymph - ✔✔Lymphatic capillaries
Lymphatic vessels
Afferent lymphatic vessel
Lymph nodes
Efferent lymphatic vessel
Lymphatic trunk
Collecting duct
✔✔Where can lymph nodes be found in the body? - ✔✔The cervical, axillary,
supratrochlear, and inguinal regions and the pelvic, abdominal and thoracic cavities.
✔✔What types of cells provide our immunity? - ✔✔T cells and B cells
✔✔T cell function - ✔✔cell-mediated immunity; helper T cells,
✔✔B cell function - ✔✔antibody production
✔✔Compare an antigen to an antibody. - ✔✔antigens cause the disease and antibodies
cure it.
✔✔Describe the thymus and its role in immunity - ✔✔The thymus is a soft, bi-lobed
gland enclosed in a connective tissue capsule. It is the place where T cells mature.
✔✔What is the function of the thymus? - ✔✔T cell maturation
✔✔What is the function of bone marrow? - ✔✔produces blood cells
✔✔What is the function of lymph nodes? - ✔✔to trap disease-causing bacteria; filters
lymph
✔✔What is the function of the spleen? - ✔✔filter blood and help fight infections
✔✔What is the function of tonsils and adenoids? - ✔✔activate defensive responses to
inhaled and intranasal antigens
