Blood I Flashcards
1
Q
functions of blood
A
- transport system
- protection
- regulation
2
Q
transport system function
A
- O2 from lungs to all cells of the body
- CO2 from cells to lungs
- nutrients from digestive tract to cells
- waste products from cells to kidneys and sweat glands
- enzymes and hormones to various cells
3
Q
protection function
A
- WBC help combat infection(phagocytosis of microorganisms and production of antibodies)
- prevention of body fluid loss by cloning mechanism
4
Q
regulation function
A
- body temperature (water it contains provides meand for dissipation of heat)
- volume of body water
- pH (by way of its buffer system)
5
Q
composition of blood
A
- plasma
- cellular elements
6
Q
plasma components
A
- liquid portion of blood
- major plasma proteins(big proteins)
- ions
- compounds such as as glucose, urea, etc
7
Q
major plasma proteins components
A
- albumin
- fibrinogen
- globulins
8
Q
fibrinogen
A
- necessary for blood clotting
- eventually becomes the blood clot
9
Q
albumin
A
- many functions, including transport and BP regulation
- very large, affects osmotic pressure
10
Q
globulin
A
-transport of lipids and antibody formation
11
Q
cellular elements that make up plasma components
A
- erythrocytes (RBC)
- leukocytes (WBC)
- thrombocytes (platelets), tiny
12
Q
erythrocytes description
A
- bicon cone shape
- no nucleus (no mitosis)
- stains reddish pink)
13
Q
erythrocytes function
A
-hemoglobin for O2 transport
14
Q
WBC: neutrophil (granulocyte) description
A
- segments nucleus
- polymorphonucleated (PMN)
- granules(contains enzymes)
15
Q
WBC: neutrophil (granulocyte) function
A
- phagocytosis of bacteria, debris, etc, increased bacterial infections
- enzymes are released and destroy bacteria
