What is a hematocrit?
|
% of erthrocytes (RBC) in blood
|
|
|
Types of leukocytes
|
Leukocytes=WBC
1. Lymphocytes 2.Monocytes 3.Eosinophils 4.Neutrophil 5.Basophil |
|
|
What is the most abundant leukocyte?
|
Neutrophil
|
|
|
What is plasma made up of
|
water, ions, plasma proteins, waste product, hormoe, resp, gases
|
|
|
Name plasma proteins and fuction
|
Albumin-most abundant plasma protein, mainain osmotic pressure (make blood concentrated)
Fibrinogen-precurosr to fibrin which clots blood |
|
|
What are components in blood
|
Erthyrocytes,Leukocytes, platelets
|
|
|
What is the dunction of platelets
|
blood clotting
|
|
|
Describe positive loop in blood clotting
|
prothrombin-thrombin that activates conversion of fibrinogen-fibrin
|
|
|
How does fluid flow out of the capillary at the arteriole end?
|
hydrostatic pressure is higher inside capillary at arteriole end, lower at venous end
|
|
|
Why is osmotic pressure lower outside capillary at the artior end and higher at venous end?
|
causes fluid to re-enter capillaries at venous end
|
|
|
What happens when hydrostatic pressure>osmotic pressure in capillary?
|
Net loss of fluids from capillary into extracellular fluid
|
|
|
When does pulmonary edema occur?
|
When hydrostatic pressure < osmotic pressure, net movement of fluid in capillaries
LV fails-blood backed out into pulmonary veins-increase osmotic pressure in lung-bring in fluid-"drown" |
