APHY 201 Module 07 Blood Ivy Tech Questions with Correct Answers
Question 1:
Plasma and formed elements (RBCs, WBCs, and platelets)
Answer:
Blood Components
Question 2:
Volume 4-6 liters. Men have another 1-2 liters than women; 8% of body weight; pH 7.35-7.45
Answer:
Properties of Blood
Question 3:
Red blood cells; lower layer of centrifuged blood; 44% of sample; 4-6 million; most of formed
elements
Answer:
Erythrocytes
Question 4:
Percent of blood volume that is RBCs
47% ± 5% for males; 42% ± 5% for females
Answer:
Hematocrit
Question 5:
Erythrocytes and buffy coat (leukocytes, platelets)
Answer:
Formed elements
Question 6:
Fluid portion of blood. Usually about 55% of whole blood.
Serum
fluid portion of blood (plasma) with clotting factors removed
Answer:
Plasma
, Question 7:
Delivering O2 and nutrients to body cells; Transporting metabolic wastes to lungs and kidneys
Answer:
Distribution functions of blood
Question 8:
Maintaining body temperature by absorbing and distributing heat; Maintaining normal pH using
Answer:
Regulation functions of blood
buffers; alkaline reserve of bicarbonate ions; Maintaining adequate fluid volume in circulatory
Question 9:
How does blood regulate pH levels?
Answer:
Preventing infection due to antibodies, complement proteins, WBCs
Blood plasma contains bicarbonate and proteins which act as buffers that may be used to
Question 10:
How does the blood regulate body temperature?
Answer:
maintain pH; 7.4 needed for normal functioning
Plasma absorbs and distributes heat. Blood vessels in dermis dilate to cool body and to
conserve
Question 11:
How does blood maintain fluid levels?
Answer:
heat.
Exchange fluid between plasma and interstitial fluid limited by plasma protein osmotic
pressure; too much fluid in blood (because of extra plasma proteins) increases blood pressure;
too much fluid in tissues (because of too few plasma proteins) causes edema. The presence of
the ideal amount of plasma proteins will maintain the correct blood volume and blood
pressure.
Question 12:
Nutrients like oxygen diffuse from blood into tissues; Wastes like CO2 diffuse from interstitial
fluid to blood so it can be carried to the lungs
Answer:
Blood Diffusion
