Back 4

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

Front 5

Diastole - Atrial/Ventricle

Back 5

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.

Structure of Heart Wall

Back 7

Parietal Pericardium-Pericardial Space-Visceral Pericardium; Epicardium, Myocardium, Endocardium

Front 8

Internal Heart Anatomy

Back 8

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.

Front 9

Blood Flow through the heart
unoxygenated

Back 9

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.

Front 10

Blood flow through the heart, oxygenated

Back 10

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

Front 11

Diastole

Back 11

Relaxation of heart

Front 12

Systole

Back 12

Contraction of the heart

Front 13

Carotid Sinus Mechanism I

Back 13

increase in bp
carotid sinus stimulated-nerve impules go to the cardioregulatory center - the sympathetic -, parasympathetic +, decreased heart rate, bp decreased.

Front 14

Carotid Sinus Mechanism II

Back 14

decreased bp, carotid sinus is not stimulated no impulses to the cardioregulatory center - sympathetic+, parasympathetic-, increased bp

Front 15

CO2 and OX mechanism I

Back 15

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.
