1-most abundant
2- the most abundant is also the...
3- second most abundant protein
4- least abundant protein |
|
Definition
1- albumin (helps osmotic pressure, keeps fluid in blood instead of leaking into organs/ body cavities)
2-smallest of plasma proteins
3-globulin immunoglobulins; "antibodies"
(defense: fight off unkwn material/ pathogens, help in transport)
4-fibrinogen (makes fibrin for clotting, removal leaves serum) |

Term
Basophils
-what percent
-granules and nucleus
-what do they release (hormone) and what does it do! |
|
Definition
-less than 1
-blue/purple granules and lobulated nucleus
-release histamine (draws other things to infection sites, causes blood to enter and heat to rise in injured tissues) |

monocytes (2-8%)
-nucleus
-what they do |
|
Definition
-bean shaped nucleus; LARGE
-mobile and phagocytic
-can enter peripheral tissues and become macrophages!
-help turn on immune system, they pick up pieces of cells and hold them up to lymphocytes who then say okay lets make more antibodies! |
