Blood Comp
RBC's(45%), Buffy coat(WBC,Platelets,1%), Plasma(55%)
Hemaglobin
carries oxygen
Macrophages
Monocytes
Hypoxia, High altitudes
kidneys release of hormone erythropoieten
Factors for Production of RBC
Fe,Folic acid, Vitamin b12
Breakdown of Hemaglobin
Heme>iron,Globin>amino acids
Agranulocytes
monocytes(macrophages) & lymphocytes(T-cells,B-cells)
Granulocytes
neutrophils(first 1 on site of infection), eosinophils(allergic reaction,parasites), basophils(histamine,heparin)
B12 Anemia
pernicious anemia
Diapadesis
When WBC squeeze through the capillary walls
WBC count
5,000-10,000
More>Leukocytosis
Less> Leukopenia
Protiens in Plasma
Globular>(gamma>antibodies, alpha&beta>transport)
Albumins>helps control BV,osmotic pressure
Fibrinogen>blood coagulation
_______is a nonprotien nitrogenous substance that derives from nulciec acid's catabolism
uric acid
catabolism of protiens
urea
locally acting horomone that begins homeostasis
Serotonin
In presence of Prothrombian activator Prothrombain is coverted to
Thrombin
Which protien is needed for insoluble clot
fibrin
Universal donor
A person with blood type O-. Because this person's red blood cells possess none of the typical blood suface proteins, they cannot initiate an immune reaction in a recipient.
Universal Recepient
Blood type AB +
Blood typing
anitgens on surface, anitbodies in plasma, RH factor
Low RBC,WBC,Thrombocytes
Pancytopenia
Septicemia
blood poisoning,presence of infective agents or their toxins in the blood stream
Herditary hemolitic anemia
Tolocemia (meditereanean region)
Layers of the heart
epicardium, myocardium, endocardium
Myocardium
Thick middle muscle layer of the heart; pumps blood through the circulatory system.
Which valve is between the right atrium and right ventricle
tricuspid
exiting valve right ventricle
pulmonary
exiting vessel of right ventricle
pumlonary trunk
valve between left atrium and left ventricle
Mitral(bicuspid)LAV
exiting valve for left ventricle
aortic valve
exiting vessel of left ventricle
aorta
Chortaid tendenae
attached to papillary muscles
After blood crosses mitral valve
left ventricle
coronary vessels are topping off(branches)
aorta
Which action from the heart is responsibles for systamic and systolic pressure
Left ventricle pushes
Right coronary artery(RAC)
posterior interventricular,Marginal
Left coronary artery(LAC)
anterior interventricular,Circumflex
Lub
AV valves closing 1st sound
Dub
semilunar valves closing 2nd sound
SA nodes
fires first(natural pacemaker)
AV nodes
in septum 2nd
bundle of HIS
Or AV bundle 3rd
Bundle branches
4th
EKG reading
first line>Pwave(atrial deplorization),first dip>QRSwave(ventricular)delporization/contraction),last part>Twave (relaxtion)
QRS complex
The QRS complex represents the electrical activity associated with the contraction of the ventricles, or ventricular depolarization and consists of the Q wave, the R wave and the S wave
Right atrium
all major blood vessels are from
Arteries
flow blood to body
Veins
flows blood back to the heart
Capillaries
For gas exchange
Calculate the Cardiac output
SV(amount of blood pushed every beat),
HR(heart rate)
SVxHR
Factors that affect Heart blood pressure
pressure,heparin>decreases viscosity of blood,blood thinner
dilating periphral viscular vascular is going to decrease blood pressure
Speeding up HR>increase blood pressure, Lowering the Venus return>decrease blood pressure
Cardiac control center
Medulla oblongata
Vagus (X nerve)
parasympathetic impulses to heart
Cardiac myopetia
cardiac failure>polar edema,pulomonary edemia,reduces flow to the kidney(hypertrophic)
Stucture of blood vessels
endothelium,Tunica interna,tunica media,tunica externa
Compression of the heart
fluid in the pericardial cavity(congestive heart failure)
Kidneys + BF
decrease-Renin-Angiotensiongen-Angoi I-Angoi II(bad guy)>2 mechanisms(vasospasm, increase aldosterone(Na+/H2O)/adrenal BP)
