Bio 202 Lab QUIZ 2
List and describe the eight functions of blood - answer1) Transport of respiratory gases
2) Regulation of pH
3) Regulation of electrolytes
4) Regulation of fluid loss (hemostasis)
5) Defense against pathogens
6) Regulation of body temp
7) Transport of hormone
8) Transport of nutrients and metabolic wastes
What are the components of blood? - answerPLASMA (46%-63%):
- Plasma proteins: Albumins, globulins, fibrinogen, regulatory proteins
-Other solutes: Electrolytes, organic nutrients, organic wastes
FORMED ELEMENTS (37%-54%):
- RBCs: transport respiratory gases (O2 and CO2)
-WBCs: Neutrophils, eosinophils, basophils, lymphocytes, monocytes- fight disease
causing pathogens
Describe hematocrit - answerA snapshot of how many RBCs are in the plasma
Define and describe RBCs including shape, structure of hemoglobin and function -
answerRBC: Transport of O2 throughout the body, Biconcave in shape, Contains the
iron protein compound hemoglobin whose chief function is to combine with oxygen and
carry it to the cells
Define and describe platelets - answerIn the plasma, used to clot the blood
Antigen - answerUnique molecules on the cell surface (used to distinguish foreign cells
and our own cells)
Agglutinogens - answerAntibody molecule binding to antigen and causes
clumping(glutination)
What tissue type is more prevalent in arteries than in veins? - answerThe tunica media
How do arteries look and feel in the cadavers? - answerThick and hard
How much pressure is blood under in an artery as compared to other vessels? -
answer120-35mmHg
Which direction does blood flow through an artery in relation to the heart? -
answerAway from heart
