1. Muscular System - ANSWER Muscle tissue found in almost every part
of the body and consists of three distinct types: Skeletal muscle, Smooth
muscle, and Cardiac muscle
2. What is the function of Skeletal muscle (striated muscle)? - ANSWER
Primary function is movement of bones
3. What are the functions of smooth muscle? - ANSWER Muscle
contractions are involuntary, Walls of blood vessels and organs of digestive
system
4. What are the functions of cardiac muscle? - ANSWER Specialized type
of striated muscle; Normally self-stimulating, producing the continuous
pumping of the heart
5. What is the primary function of the circulatory system? - ANSWER
Primary function of circulatory system is to remove carbon dioxide and
waste products from cells.
,6. What does the circulatory use in order to function? - ANSWER The
medium transport is blood. Blood is composed of a plasma portion and
several types of cellular elements. Plasma comprises 55 percent of total
blood volume.
7. Erythrocytes are - ANSWER most abundant type of blood cell.
8. Where is erythrocytes produced? - ANSWER Produced primarily in the
bone marrow and aids the transport of respiratory gases
9. What are Leukocytes and what are the 2 main types? - ANSWER Less
abundant than RBCs, Granulocytes and Lymphoid cells
10.What are granulocytes and how are they classified? - ANSWER
Relatively large cells; nuclei are multi-lobed; cytoplasm contains
microscopic granules; Classified based on straining properties:
11.What are the classifications of granulocytes? - ANSWER Neutrophils,
Eosinophils, Basophils
12.Lymphoid cells - ANSWER Most commonly occur in lymph vessels and
in the nodes along these vessels;- monocytes; - lymphocytes; Lymphoid and
small white blood cells help make up the immune system
13.Thrombocytes - ANSWER Platelets essential for blood clotting;
formation of hemostatic plugs or clots; serum
,14.monocytes - ANSWER Large lymphoid cells
15.lymphocytes - ANSWER Small white blood cells
16.What is the structure of the Circulatory System? - ANSWER Heart - four
chambers in mammals and birds
17.What are the three separate tissue layers that compose the heart? -
ANSWER Myocardium; Epicardium, Endocardium
18.Myocardium - ANSWER heart muscle
19.Epicardium - ANSWER covers outer surface of myocardium
20.Endocardium - ANSWER delicate layer of tissue lining the inside of the
heart's chambers
21.The heart has 2 halves that each contain... - ANSWER Each contains an
atrium and a ventricle, which acts to collect blood and circulate it
throughout the body
22.What are the 3 types of blood vessels? - ANSWER Arteries, Veins, Blood
capillaries; Blood passes from the capillaries into the venous system; first
through venules and then veins
, 23.What is the function of the arteries? - ANSWER Carry blood away from
the heart
24.What is the function of the veins? - ANSWER Return blood to the heart
25.What is the function of the blood capillaries? - ANSWER Connect
arteries and veins
26.Facts about veins - ANSWER Carry blood at pressures lower than
arteries. Venous systems act as reservoir. Hold roughly 60% of total blood
volume. Largest vein in body: Vena Cava, which lies next to the aorta. Vena
cava empties into the right atrium.
27.Circulation Control - ANSWER Blood flows from an area where pressure
is greater to an area where it is lower. Left ventricle is source of highest
pressure. Blood pressure is recorded as diastolic and systolic pressures.
Diastole occurs as the blood flows in and the ventricle is at rest. Systole
occurs as the mitral valve closes just as the ventricle begins to contract.
Blood is taken from the ventricles during a cardiac puncture procedure.
28.Diastolic pressure - ANSWER occurs as the blood flows in and the
ventricle is at rest.
29.Systolic pressures - ANSWER occurs as the mitral valve closes just as
the ventricle begins to contract
30.Lymphatic System - ANSWER the filter mechanism for the body; it
provides one of the major defenses against pathogenic invasion
