which layer of the heart forms the valves?
Definition
endocardium
Term
systemic venules
Definition
venules of the body
Term
position of heart in chest
Definition
left of medial
Term
another name for visceral pericardium
Definition
epicardium
Term
order of the conduction of the heart
Definition
SA node, AV node, AV bundle, Bundle branches, Purkinje fibers
Term
=systole=
Definition
=ventricle Contraction=
Term
what does the skeleton of the heart do
Definition
gives stability to the cardiac muscle fibers
Term
stroke volume
Definition
the amount pumped out of one ventricle during one contraction
Term
cardiac output
Definition
the amount of blood contracted out of one ventricle in one min.
Term
cardiac reserve volume
Definition
the difference between resting and max cardiac output
Term
parasympathetic stimulation does what to heart rate
Definition
decreases heart rate
Term
sympathetic stimulation does what to heart rate
Definition
increase heart rate
Term
EDV
End Distolic Volume
Definition
How much blood is in the ventricle at the end of relaxiation (large amount of blood in ventricle)
Term
ESV
End Stystemic Volume
Definition
How much blood is in the ventricle at the end of systole (least amount of blood in ventricle)
Term
how to find stroke volume
Definition
160- 80 =80
EDV- ESV =SV
how much blood in ventricles when full-how much blood is in ventricle when emptied.
Term
what part of the brain controls the regulation of heart rate?
Definition
medulla oblongata
Term
without BP (MAP) neutrants and waste would not be able to reach their target tissue because BP is what propels blood around the body.
Definition
without BP (MAP) neutrants and waste would not be able to reach their target tissue because BP is what propels blood around the body.
Term
what is mean arterial pressure?
Definition
how much blood pumps out v/s pressure against the walls of the arteries.
Term
Barorecptor
Definition
sense pressure and send signal to change heart rate, change diolation of veins and arteries.
Term
cardiac tamponade
Definition
blood in the plural space
Term
systemic blood / pulmonary blood
Definition
Body blood / lung blood
Term
What lines the capillary
Definition
endothelium
Term
Tunica intima
Definition
lines inside of all vessels(endothelium)
Term
Tunica media
Definition
Middle of all vessels(smooth muscle)
Term
Tunica externa
Definition
Outside of all vessels(collagen fibers)
Term
vasa vasorum
Definition
blood vesicles that carry blood to thick walled arteries
Term
anastomosis
Definition
the joining of nerve, blood, or lymph vessels
Term
colloid osmotic pressure
Definition
pressure in fluid created by non diffusiable stuff in blood like plasma proteins this draws water to it!!!
Term
Blood Flow to the Kidney
Definition
Descending Aorta, Renal Artery, Kidney, Renal Vein, Inferior Vena Cava
Term
Blood flow Liver and Back
Definition
Descending Aorta, Cephalic Trunk, Common Hepatic A, Hepatic A. Liver, Hepatic Veins, Inferior Vena Cava
Also, blood from stomach, spleen, and intestine are carried via the hepatic portal system to the liver and it returns via hepatic veins to inferior vena cava
Term
Blood flow from Leg and Back
Definition
Descending Aorta, Common Iliac, external Iliac, Femoral, popliteal A., splits to the anterior & Posterior tibial A, anterior and post tibial V., popliteal v., femoral v., external iliac, common iliac, inferior vena cava
Term
metabolic
Definition
expending energy
Term
atrial Natriuretic Peptide
Definition
causes blood volume and blood pressure to decline
Term
ADH
Definition
causes intense vasoconstriction causes BP to increase
Term
Renin-angiotensin mechanism causes
Definition
increases blood pressure
Term
Angiotensin II causes
Definition
vasoconstriction
Term
epinephrine causes
Definition
vasoconstriction and increases cardiac output
Term
Aldosterone
Definition
released by adrenal cortex which makes kidneys reabsorb Na, which causes them to take up fluid, which "thickens blood" lol which increases BP
Term
vasodilation
Definition
artery to get larger
Term
Superior mesenteric
Definition
supply small intestine, and right side of lg intestine
Term
inferior mesenteric
Definition
left half of lg intestine
Term
Ca+ prolongs depolization phase in heart
