3 functions of blood
|
1.) transport system
2.) Protection 3.) Regulation |
|
What does blood transport?
|
*O2 from the lungs to all cells of the body
*CO2 from cells to the lungs *nutrients from digestive tract to cells *waster products from cells to kidneys and sweat glands *enzymes and hormones to various cells |
|
what type of cell helps combat infection?
|
white blood cells
|
|
body fluid loss is caused by
|
clotting mechanism
|
|
composition of blood
|
55 % Plasma
45% Cellular elements |
|
Composition of plasma
|
1.) 90% water
2.) plasma proteins 3.) ions 4.) compounds like glucose and urea |
|
3 types of plasma proteins
|
1.) Albumin
2.)Fibrinogen 3.) Globulins |
|
function of albumin
|
-helps with transport and blood pressure regulation
-very large, effects osmotic pressure |
|
fibrinogen
|
(plasma protein)
-necessary for blood clotting -when converted to fibrin it forms a clot |
|
globulins
|
(plasma protein)
- transport of lipids and helps with antibody formation |
|
3 things that make up the cellular elements in the blood that make up 45% of blood
|
1.) Erythroctes (red blood cells)
2.) Leukocytes (white blood cells) 3.) Thrombocytes (platelets) |
|
which two cellular elements in the blood make up the "buffy coat"
|
Leukocytes,and thrombocytes
|
|
1.)function and 2.)lifespan of erythrocytes (RBC)
3.) and description |
1.) hemogobin for oxygen transport
2.) lifespan= 120 days 3.) no nucleus, stains pink, "bi-concave discs" |
|
Neutrophil (WBC)
1.) function 2.) lifespan 3.) description |
1.) increases in bacterial infections
2.) a few hours 3.) granules= contains enzymes, polymorephoncleated |
|
Eosinophil (WBC)
1.) function 2.) lifespan 3.) description |
1.) fights parasitic infections and allergies
2.) n/a 3.) bi-lobed nucleus, large pink granules |
|
Bosophir (WBC)
1.) function 2.) lifespan 3.) description |
1.) contains histamine, increase in WBC's, affects vascular permeability
2.)n/a 3.) lobed nucleus, dark granuoles |
|
Monocytes (WBC)
|
1.) Phagocytosis, moves into tissues and becomes a macrophage
2.) n/a 3.) largest nucleus, blue cytoplasm |
|
Lymphocytes (WBC)
1.) function 2.) lifespan 3.) description |
1.) increased inviral infections, immune defense, fights viral infections
|
|
Thrombocytes (Platelets)
1.) function 2.) lifespan 3.) description |
1.) clotting
2.) n/a 3.) resides in bone marrow, small granular fragements |
|
where are embryonic and fetal development blood cells formed?
|
yolk sac, liver, spleen, thymus, lymph nodes, and bone marrow
|
|
in the adult where are blood cells formed?
|
in red bone marrow of:
*ribs, vertebrae, pelvis, head of humerus and femur and in "lymphoid tissue"(lymph nodes, tonsils, and spleen) |
|
bone marrow in adults
|
50% red and 50% yellow***
|
|
where is bone marrow located?
|
in long and flat bones
|
|
which marrow contains a large number of fat cells?
|
yellow marrow
|
|
which marrow is blood forming?
|
red marrow
|
|
what is the bone marrow like at birth?
|
red
|
|
what is erythropoietin?
|
hormone produced in the kidney that influences the rate of production of blood cells
