Blood Flashcards
Blood Composition
55% plasma
45% formed elemetns
Plasma compotition
90% water
10% plasma proteins, gases, nurtrients, electrolytes, hormones
What are
Plasma Proteins
Albumin, Globulin, Firbrogen
what is…?
Albumin
Helps with osmotic pressure - causes fluid to remain in blood vessels as opposed to your tissues
what is…?
Globulin
plasma protien that will produce other proteins
what is…?
Fibrinogen
plasma protine that is inactivated - but when activated into fibrin helps blood coagulate/clot
Formed Elements compostion
99% erythrocytes
what are…?
Formed Elements
Erthyrocytes, Leukocytes, and Throbocytes
Where are… made? what do they do? decribe them? What are they made of?
Erythrocytes
- made in red bone marrow
- transport blood gasese - O2 and CO2
- no nucleus, biconcave disc
- hemoglobin
Life span of erythrocytes
how long do they live for, where are they recycled?
90-120 days; recycled in spleen/liver
what is…?
Hemoglobin
four part quartinary protien (4 heme groups, with an element of iron in the middle)
What does iron do in hemeglobin
binds reverably with O2
what does … do?
Globin
makes other protiens
what are …?
Thrombocytes
also known as platelets
a formed element that helps clotting (hemostasis)
What is…?
Hemostasis
A three step process that allows a clot to form
the three steps are;
1. vascular spasm
2. platelet plug
3. coagulation
