Blood functions are:
|
-carry O2, CO2, nutrients, hormones, proteins, sugars, wastes, cholestrol, lipids, etc.
-protect the body from pathogens and blood loss -regulate body: temp, salts, chemicals, acids |
|
|
Where are blood cells produced?
|
In the epiphysis- the red marrow in the spongy bone
|
|
|
red blood cells
|
transport O2 and CO2
|
|
|
lymphocytes
|
active in specific immunity
|
|
|
monocytes
|
become large phagocytes
|
|
|
neutrophils
|
phagocytises pathogens
|
|
|
basophils
|
release histamine
|
|
|
platelets
|
aid blood clotting
|
|
|
hemoglobin
|
O2 carrying protein
|
|
|
plasma proteins
|
maintain homeostasis of blood, don't leave the blood bc of osmotic pressure:
ex. albumin, globulin, fibrogen |
|
|
albumin
|
contribute most to osmotic pressure, transport other molecules
|
|
|
globulin
|
help transport substances like hormones, cholestrol, an iron, and fight disease
|
|
|
fibrogen
|
inactive: once active it forms blood clots
|
|
|
hemoglobin
|
contains heme molecule; carries oxygen; iron gives blood red color
|
|
|
O2/CO2
|
blood drops of O2 and picks up CO2 at cells, and drops of CO2 and picks up O2 at lungs
|
|
|
macrophages
|
eat red blood cells in liver at the end of the RBC 120 day life cycle
|
|
|
jaundice
|
results from liver failure bc of build up of heme in body
|
|
|
erythropoietin
|
hormone release by bone marrow to stimulate RBC production in bone marrow
|
|
|
innate WBC
|
monocytes, natural killer cells, neutrophils
|
|
|
adaptive WBC
|
lymphocytes, B cells and T cells
|
|
|
clotting cascade
|
puncture-->plates form a plug --> prothrombin --> thrombin --> fibrogen --> fibrin........ afterwards plasmin destroys clot to allow cells to regrow
