Blood Flashcards
How much blood is out body weight
7%
about 6-7L in average human
what is RBC carried on?
hemoglobin
hematocrit is a measure of what?
% of blood that is Red blood cells (42-45%)
how many red blood cells do you have in 1cc of blood?
4.5-5.5 miller per cc of blood
how does your body generate heat?
when your cells metabolize they generate heat, and that heat is transferred to the blood, then the blood radiates the heat around the body.
in a normal cell metabolism what should the acids (H+) be used for at the cell level?
to work in the Kreb cycle and electron transport chain to make ATP.
when will there be a VQ mismatch (more CO2 in blood) than what CO2 is measured coming out of the pt?
when a pt has a PE
how many types of white blood cells (leukocytes) are there?
5
how doest blood clot?
use of platelets
what are the formed elements of blood?
- erythrocytes (RBC)
- 4.5-5.5 million
- Platelets
- 250,000-400,000
- Leukocytes (WBC)
- 2%, the rest lives in the tissues
not having enough red blood cells is called?
anemia
- find out why they dont have enough red blood cells.
why dont RBC reproduce?
they have no mitochondria
what two type of WBC?
Granular and Agranular
what are granular WBC?
eoxinophils
basophils
nutrophils
What are agranular WBC?
Lymphocytes
Monocytes
neutrophils
phagocytes (eat cells)
eosinophils
effective against parasitic worms
Basophils
inflammatory and allergic reactions
lymphocytes
bacteria
virusis
natural killer cells
platelets Thrombocyte
no nucleus
many granular
used to stop bleeding
chemical messengers
what is INR?
the ratio and measure the bodies ability to create clots and plug.
what is D-dimmer test?
measurement of dissolved clots
common taken to see if someone is actively bleeding
what is the hemopoeitc stem cell?
the start of a creation cell, and it creates type of blood cell based of body needs.
polycythemia vera
cyanotic looking (not enough O2 to attach to blood cells, and low pulse ox
inappropriate increase in red blood cells
Primary (rapid over production of red blood cells)
Usually cancer based
spontaneous bruising, less platelets because more red blood cells have been created.
polycythemia
the creation of more blood cells, in response to something
ex: living at altitude, COPD, ect.
Leukemia, how many types?
cancer, bone marrow cancer.
Acute: making too many
Chronic: not getting rid of them
Hair cell leukemia:
why will leukemia be anemic?
they are not differentiating in making red blood cells and making more white blood cells.
hemophilia
“love to bleed”
- they can not clot adequately
- body missing clotting factors
- genetic (get from mother)
Acquired Immune Deficiency Syndrome
AIDs
Human R lymphotropic virus type III (HTLV-III) (HIV)
Blood to blood and semen to blood contact
Destroys T-cells, the cells the fight infection.
they will die from an infection, not AIDS itself
what part of the blood carries clotting factors?
plasma
