Blood Flashcards
Functions of Blood (3)
- transportation
- regulation
- protection
Amount of blood
- 38-48% is composed of various blood cells
- 52-62% of blood volume is plasma
Color of blood
Arterial: bright red
Venous: Darker, dull red color
pH of blood
- normal pH range 7.35-7.45
- slightly alkaline
Viscosity of blood
- thickness or resistance to flow
- approximately 3-5 times thicker than water
Plasma
- Liquid part of blood
- Most of the carbon dioxide produced by cells is carried in the plasma
- Prothrombin and Fibrinogen
what kind of proteins does the plasma contain and where is it synthesized?
- plasma protein
- liver
- Albumin &Globulins
Albumin
- in plasma
- maintenance of blood pressure
Globulins
-(alpha & beta) to act as carriers and beta globulins that are antibodies produced by lymphocytes
beta globulins
antibodies produced by lymphocytes
RBC
- Erythrocytes
- Biconcave discs
- Only cell without a nuclei
RBC function
- Carries oxygen
- Some carbon dioxide is carried through the RBC’s-only about 10% of total CO2 transport
RBC- Production and Maturation
- Formed in red bone marrow
- Hemocytoblasts
- Erythopietin
RBC- life span
- Approximately 120 days
- Iron is recycled on repeat
- Heme cannot be recycled and is a waste product
where do blood types come from?
-Genetic: inherited genes from our parents
