APHY 102 – Blood UPDATED ACTUAL
Questions And CORRECT Answers
Interstitial Fluid - CORRECT ANSWER- ✔✔Fluid in body tissues surrounding body cells
What kind of tissue is blood? - CORRECT ANSWER- ✔✔Connective tissue
Blood Components - CORRECT ANSWER- ✔✔Plasma and cells
How is blood divided? - CORRECT ANSWER- ✔✔Liquid and cellular components
Function of Blood - CORRECT ANSWER- ✔✔Transport oxygen, nutrients
Regulate heat, p
Clotting
Blood Diffusion - CORRECT ANSWER- ✔✔Oxygen diffuses from blood into tissues; CO2
diffuse from interstitial fluid to blood so it can be carried to the lungs
Properties of Blood - CORRECT ANSWER- ✔✔Men have another 1-2 liters than women;
8% of body weight; pH 7.35-7.45
How does blood maintain fluid levels? - CORRECT ANSWER- ✔✔Exchange fluid between
plasma and interstitial fluid; too much fluid increases blood pressure
How does blood regulate pH levels? - CORRECT ANSWER- ✔✔Blood plasma compounds
and ions may be dsitributed to fluid to maintain pH; 7.4 needed for normal functioning
How does the blood regulate body temperature? - CORRECT ANSWER- ✔✔Plasma absorbs
and distributes heat
Blood vessels in dermis dilate to cool body
Blood vessels constrict to conserve heat
, Centrifuge - CORRECT ANSWER- ✔✔Blood is spun in a circular motion; separates liquid
and cellular components
Erythrocytes - CORRECT ANSWER- ✔✔Red blood cells; lower layer of centrifuged blood;
44% of sample; 4-6 million; most of formed elements
Buffy Coat - CORRECT ANSWER- ✔✔Thin, middle layer of white blood cells; <1%
Formed elements - CORRECT ANSWER- ✔✔Erythrocytes and buffy coat (leukocytes,
platelets)
Plasma - CORRECT ANSWER- ✔✔Top of tube; 55% of blood
Plasma Components - CORRECT ANSWER- ✔✔92% water
7% proteins
1% other solutes
What are the plasma proteins? - CORRECT ANSWER- ✔✔Albumin, globulin, fibrinogen
What is the ratio of plasma proteins to plasma? - CORRECT ANSWER- ✔✔6-8 g/100 ml
What is the function of plasma proteins? - CORRECT ANSWER- ✔✔Maintain osmotic
pressure
Albumins - CORRECT ANSWER- ✔✔Smallest and most abundant protein; osmotic balance;
54%
Globulins - CORRECT ANSWER- ✔✔Second largest group 37%; antibody production
Fibrinogen - CORRECT ANSWER- ✔✔4% of proteins; blood clotting
