Functions of the cardiovascular system
Transport- oxygen, CO2, nutrients to the cells, waste products from the cells, and hormones
Maintain- acid-base balance, fluid-electrolyte balance
Provide- body defense and protection
Oxygenated blood is pumped from this chamber to the body--discuss the pathway
Left Ventricle to aortic valve to aorta
middle layer, thickest, composed of cardiac muscle which contracts and pumps blood through the blood vessels
What is myocardium
The NUMBER OF times the sinoatrial node IS set to discharge per minute--a normal persons heart rate--NSR
What is 60-100
area of the anterior chest
wall overlying the heart and great vessels
What is precordium
Slinglike structure that supports the heart and attaches to surrounding structures
What is the pericardium
Left Sided Heart Pump
What is Systemic circulation Pulmonary veins to Left atrium through Mitral valve to left ventricle to aortic valve to aorta to BODY
Ventricular repolarization
What is t wave
The electrical impulse system of the heart is evaluated by this test
What is EKG, ECG
innermost layer, also lines the values and covers the blood vessels that enter and leave the heart
What is endocardium
WHERE CAN YOU HEAR S1 (PMI)
What is THE MITRAL VALVE--5th intercostal space mid clavicular line--APEX
Atrial depolarization
What is the P wave
All the events that occur in one heartbeat
Cardiac cycle
What is happening when S2 is heard?
What is aortic and pulmonic (semilunar valves) are closing. End of systole
WHERE CAN YOU HEAR S2?
What is At the aortic and pulmonic valves-Base of the heart--2nd Rib
thin outermost layer of the heart that helps form the pericardium.
The lub sound is caused by this and this sound can also be referred to as
What is S1 and the closure of the A/V valves
The pathway of the electrical system through the heart
What is SA node, AV node, Bundle of HIS, Bundle branches, Purkinje Fibers
Deoxygenated blood comes from the body through this structure
What is the vena cava
Right sided heart pump
Pulmonary circulation
Vena cava to right atrium through tricuspid to right ventricle to pulmonary artery to LUNGS
DAILY DOUBLE What can you hear at ERB'S POINT?
What is S1 AND S2 EQUALLY
