Circulatory System

Question 1

Know the importance & components of the blood:

Answer 1

Blood is absolutely vital for life. About 55% of the total blood volume is a liquid called “plasma”; the remainder consists of red blood cells, white blood cells, and platelets. Plasma contains: albumin, globulins, & fibrinogin

Question 2

Albulin:

Answer 2

regulates the amount of water in the blood (is produced by the liver)

Question 3

Globulins:

Answer 3

help transport fats throughout the body and fight infections (produced in liver and lymph tissue)

Question 4

Fibrinogin:

Answer 4

helps with the clotting of the blood (produced in liver)

Question 5

Hemoglobin:

Answer 5

found in the cytoplasm of red blood cells, binds easily to oxygen and gives blood its characteristic red color

Question 6

Sickle cell anemia:

Answer 6

genetic defect in hemoglobin molecules that makes them clump together into elongated crystals in certain conditions

Question 7

Know the different blood types and the meaning of the classification:

Answer 7

A person can have type A blood (only antigen A present), type B blood (only antigen B), type AB blood (both antigens), or type O blood (neither antigen). People with type A blood have anti-B antibodies and can receive transfusions of blood that do not have antigen B (A & O) but they cannot receive blood that contains antigen B (B & AB). People with type AB are “universal recipients”; people with type O are “universal donors”. People whose blood contains the Rh factor are considered “Rh positive”, and people whose blood lacks this factor are “Rh negative”
