APHY 201 Module 07 Blood Ivy Tech Exam Questions with Correct Answers
Question 1:
circulatory system
Answer:
....composed of blood, heart and blood vessels
Question 2:
Blood Components
Answer:
....Plasma and formed elements (RBCs, WBCs, and platelets)
Question 3:
Properties of Blood
Answer:
....Volume 4-6 liters. Men have another 1-2 liters than women; 8% of body weight; pH 7.35-7.45
Question 4:
Erythrocytes
Answer:
....Red blood cells; lower layer of centrifuged blood; 44% of sample; 4-6 million; most of formed
elements
Question 5:
Hematocrit
Answer:
....Percent of blood volume that is RBCs 47% ± 5% for males; 42% ± 5% for females
Question 6:
Formed elements
Answer:
....Erythrocytes and buffy coat (leukocytes, platelets)
,Question 7:
Plasma
Answer:
....Fluid portion of blood. Usually about 55% of whole blood.
Question 8:
Serum
Answer:
....fluid portion of blood (plasma) with clotting factors removed
Question 9:
Buffy Coat
Answer:
....Thin, middle layer of white blood cells; <1%
Question 10:
Categories of blood function
Answer:
....Distribution, regulation, protection
Question 11:
Distribution functions of blood
Answer:
....Delivering O2 and nutrients to body cells; Transporting metabolic wastes
Question 12:
Transporting hormones from endocrine organs to target organs
Answer:
to lungs and kidneys for elimination;
Question 13:
Regulation functions of blood
Answer:
....Maintaining body temperature by absorbing and distributing heat;
Maintaining normal pH using buffers; alkaline reserve of bicarbonate ions; Maintaining
adequate fluid volume in circulatory system with presence of plasma proteins and sodium
, Question 14:
Protection functions of blood
Answer:
....Preventing blood loss due to plasma proteins and platelets initiating clot
Question 15:
Preventing infection due to antibodies, complement proteins, WBCs
Answer:
formation
Question 16:
How does blood regulate pH levels?
Answer:
....Blood plasma contains bicarbonate and proteins which act as
buffers that may be used to maintain pH; 7.4 needed for normal functioning
Question 17:
How does the blood regulate body temperature?
Answer:
....Plasma absorbs and distributes heat. Blood vessels in dermis dilate to cool body and to
conserve heat.
Question 18:
How does blood maintain fluid levels?
Answer:
....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 19:
Blood Diffusion
Answer:
....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
Question 1:
