Blood!!!!🩸 Flashcards
Neutrophils
defense against bacteria
lymphocytes
makes antibodies
monocytes
destroys pathogens
eosinophils
fights parasites
basophils
release histamine (important for inflamation)
Luekocytes
white blood cells
Leukocytosis
WBC count is too high
Lyopenia
WBC count is too low
Erythrocytes
Red Blood Cells
Polycythemia
RBC count is too high
Anemia
RBC count is too low
EPO hormone
released by kidneys- signals when RBCs need to be made
Process of Clotting
- vessel gets injured - collagen and VWF
- Platelets stick –> becomes activates
- activated platelets release
a) serotonin (spasm)
b) ADP & Thromboxane A2 (recruit more platelets)
c) thrombin (fibrinogen–>fibrin)
pH of blood
7.35-7.45
Acidosis
pH of blood is too high
Alkalosis
pH of blood is too low
Organs* involved in RBCs
Liver, spleen, kidney, bones
When there is low O2,
Kidney and liver release EPO to stimulate red bone marrow to increase RBC count so blood will have higher amount of o2
Clotting Imbalances
Deep Vein Thrombosis (big clot in a vein)
Embolus (clot breaks off and moves through vein)
hemophilia
Pericardium
layer around the heart
Layers of the heart
- epicardium
- myocardium
- endocardium
Systole
contraction
Diastole
relaxation
Conduction system
SA node, AV node, bundle of His, bundle branches, Purkinje fibers
