LATEST QUESTIONS AND ANSWERS.
General Function of Blood
transportation, regulation, protection
What is Plasma?
liquid portion of blood
Mixture of substances dissolved or suspended in water
Formed elements of blood
erythrocytes, leukocytes, platelets
(RBC) (WBC)
Hematocrit
the ratio of the volume of red blood cells to the total volume of blood
35-46% in women
40-54% in men
Red Blood Cells
Also called erythrocytes. Tiny biconcave discs, thin near center and thicker near their rim.
Hemoglobin
Oxygen carrying pigment in red blood cells
Where are Red blood cells produced?
After birth Red blood cells are produced by tissue lining in the spaces in bones which are filled with red
bone marrow
Red Blood Cell Formation
erythropoiesis
Vitamin necessary for red blood cell production
Vitamin B12 and Folic Acid
Anemia
A condition in which the blood is deficient in red blood cells, in hemoglobin, or in total volume.
Life span of a red blood cell
120 days
Erythropoietin
, A hormone produced and released by the kidney that stimulates the production of red blood cells by the
bone marrow.
damaged red blood cells
removed from circulation by macrophages
Erythrocytes ATP production
anaerobic
Products of hemoglobin breakdown
Bilirubin and heme pigment
Five types of white blood cells
neutrophil, eosinophil, basophil, lymphocyte, monocyte
Never Let Monkeys Eat Bananas
Functions of Neutrophils
Phagocytize bacteria and release antimicrobial chemicals
Function of esinophils
They kill certain parasites. Help control inflammation and allergic reactions by removing biochemicals
associated with those reactions
Function of basophils
release histamine (anti inflammatory) and heparin (anti coagulant)
function of lymphocytes
produce antibodies
function of monocytes
phagocytosis; develop into macrophages in tissues
Granulocytes
neutrophils, eosinophils, basophils
Agranulocytes
lymphocytes and monocytes
What active white blood cells are the most active phagocytes?
neutrophils and monocytes
functions of platelets
