Oxygenated Blood Flow
pulmonary circulation, pulmonary veins, left atrium, bicuspid, left ventricle, aortic valve, aorta, system.
Unoxygenated Blood Flow
superior vena cava, right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary trunk, lungs
Systole - Atrial
Atriole filling 30% AV open Semi-lunar closed EKG - P no sounds ventricular volume curve increasing, ventricular pressure curve - slight increase aortic pressure flat, atrial pressure up, atrial/ventricular repolarization
Systole - Ventricle
pumping - SV stroke volume AV closed semi-lunar open EKG-QRS sounds 1st VVC - decrease, VPC - increase, atrial pressure - increase, aortic pressure - increase
atrial/ventricular repolarization
Diastole - Atrial/Ventricle
filling 70%, 3rd heart sound, EKG flat, aortic pressure flat, atrial pressure flat, atri-ventricles repolarized

EKG T
2nd heart sound, VV - flat, VP - down, AO - down, ATP flat - ventricular repolarization/atria repol.
Diastole - atrial
pumping - SV stroke volume AV closed, semi-lunar open, EKG-QRS, 1st sound, VVC - decrease VPC - increase, aortic pressure increase, atrial pressure - slight increase, atrial/ventricular repolarization
Structure of Heart Wall
Parietal Pericardium-Pericardial Space-Visceral Pericardium; Epicardium, Myocardium, Endocardium
Internal Heart Anatomy
from R-L; superior vena cava, right atrium, tricuspid valve, chordae tendineae, right ventricule, pulmonary. left pulmonary artery, pulmonary valve, left atrium, bicuspid valve, papillary muscle, myocardium.
Blood Flow through the heart
unoxygenated
Blood flows through superior and inferior vena cava, enters into the right aorta, flows through the tricuspid valve into the right ventricle, pumped through the pulmonary semilunar valves, through the pulmonary trunk to the lungs.
Blood flow through the heart, oxygenated
blood flows into the pulmonary veins from the lungs, goes into the left atrium, through the bicuspid valve, into the left ventricle, pushed through the aortic semilunar valve into the aorta and into the body
Diastole
Relaxation of heart
Systole
Contraction of the heart
Carotid Sinus Mechanism I
increase in bp
carotid sinus stimulated-nerve impules go to the cardioregulatory center - the sympathetic -, parasympathetic +, decreased heart rate, bp decreased.
Carotid Sinus Mechanism II
decreased bp, carotid sinus is not stimulated no impulses to the cardioregulatory center - sympathetic+, parasympathetic-, increased bp
CO2 and OX mechanism I
increase in CO2, decrease in O2 - impulses reach cardioregulatory center - sympathetic +, parasympathetic -, cardiac nerves are contacted (vagus nerve), heart increases HR, CO2 goes down, O2 up.
Oxygenated Blood Flow
pulmonary circulation, pulmonary veins, left atrium, bicuspid, left ventricle, aortic valve, aorta, system.
