,WBC's - ANS they are there to support the immune system
Platelets - ANS included in blood clotting
Hematocrit - ANS the percentage of RBC's out of total blood volume
Components of whole blood when you get blood taken - ANS Plasma (top of tube and
yellow) 55% of whole blood
Erythrocytes (bottom of tube and yellow) 45% of whole blood
Buffy coat - leukocytes and platelets (middle) <1% of whole blood
In the tube after blood is taken, which of the 3 components of whole blood are considered
formed elements? - ANS buffy coat and erythrocytes
Physical characteristics and Volume of blood? (temp? colour? pH? volume? feeling/taste? body
weight?) - ANS - sticky, opaque fluid with a metallic taste
- colour: scarlet to dark red
- the pH of blood is 7.35-7.45 (just above normal)
- temperature is 38 degrees celsius
- average volume: 5-6 L for males and 4-5 L for females
- blood = approximately 8% of body weight
Blood leaves the heart via ______ that branch repeatedly until they become _________ -
ANS arteries, capillaries
What does O2 and nutrients do? - ANS diffuse across the capillary walls and enter tissues to
where they need to go
What does CO2 and wastes do? - ANS moves from the tissues into the blood (OUT)

, What are the 3 functions of blood? - ANS - substance distribution
- regulation of blood levels of particular substances
- body protection
Distribution (Function 1) - ANS blood transports:
- oxygen from the lungs and nutrients from the digestive tract
- metabolic wastes from cells to the lungs and kidneys for elimination (ex. CO2)
- hormones from endocrine glands to target organs
Regulation (Function 2) - ANS blood maintains:
- appropriate body TEMPERATURE by absorbing and distributing heat (when we turn red, heat
coming to surface to release into the environment)
- normal pH in body tissues using buffer systems (bicarbonate ions)
- adequate fluid VOLUME in the circulatory system (osmotic pressure)
Protection (Function 3) - ANS blood prevents blood loss by:
- activating plasma proteins and platelets (hemostasis)
- initiating clot formation when a vessel is broken
blood prevents infection by:
- synthesizing and utilizing antibodies
- activating complement proteins
- activating WBC's to defend the body against foreign invaders
How many solutes does blood plasma contain, anad what are they? - ANS blood plasma
contains over 100 solutes:
- proteins: ALBIUM (maintain osmotic pressure between blood and tissues), alpha beta &
gamma globulins, clotting proteins and others
- lactic acid, urea, creatine
- organic nutrients: glucose, carbohydrates, amino acids
