PHYSIOLOGY Flashcards
foreign substance in our body
Antigens
fight foreign substance (Antigens)
Antibody
clump of antigen-antibody complex. forms when incompatible blood type is mixed with each other
Agglutination
prevent blood loss, also known as blood clotting
Coagulation`
Coagulation Cascade
First meron tayong endothelial cell sa blood vessel tapos pag nagkasugat tayo iallow nya na magintearact ang tissue factor and Factor VIIA then yun yung simula ng coagulation cascade
First:
1. Thromboxane - activate platelets and mag vasoconstrict yung blood vessels
- Platelets will produce serotonin and adeno diphosphate which causes platelet aggregation
- Glycoprotein IIIB/IIA will replace its receptors so that yung platelets will go with fibrin
Second part:
Factor VIIA -> XA -> V -> II (prothrombin) -> IIA (thrombin) -> I (Fibrinogen) -> IA (Fibrin)
=platelets stuck in fibrin
Plasminogen can tunaw the clot/fibrin
protein that contains iron in the RBC that delivers oxygen and transports carbon dioxide from organ to lungs; contains four heme groups and can bind 4 oxygen atoms
Hemoglobin
Affinity of oxygen is higher than carbon monoxide when it comes to hemoglobin
False - bc CO has more affinity to hemoglobin so kapag many ang CO natin we will be poisoned then you will die <33 and you won’t have enough oxygen
Color of oxygenated blood
Bright Red
Color of deoxygenated blood
Dull Red
contains several atoms and can carry 1 oxygen molecule
Hemerythrin
color of deoxygenated Hemerythrin
colorless
color of oxygenated Hemerythrin
Purple
contains 2 copper atom and can combine with 1 oxygen atom
Hemocyanin
color of deoxygenated hemocyanin
Colorless
color of oxygenated hemocyanin
Light Blue
