Heart Structures
This is heart muscle
Myocardium
This is the largest artery in the body.
The aorta
This node is the normal site of origin of the electrical impulse for the heart.
The SA node
This is where carbon dioxide and other waste products are removed.
The lungs
Brief period when heart tissues are not getting enough oxygen
Angina
thick, fibrous membrane that surrounds heart
Pericardium
These large veins return deoxygenated blood to the heart.
The Superior and Inferior Vena Cava
What is the normal intrinsic heart rate or beats per minute in a healthy adult?
60-100 beats per minute.
These veins are where freshly oxygenated blood is returned to the left atrium.
The pulmonary veins.
This is the actual death of cells in the area of the heart where blood flow is obstructed.
Acute Myocardial Infarcation
Visceral layer of the pericardium lies against heart
Epicardium
The deoxygenated blood flows to this atrium first.
The right atrium.
This is considered the pacemaker of the heart.
The SA node.
After oxygenated blood has been delivered by the capillaries, this is where the deoxygenated blood is returned.
The heart.
Name the 6 pulse points in the body
Carotid pulse. Femoral pulse. Brachial pulse. Radial pulse. Posterior tibial pulse. Dorsalis pedis pulse.
This reduces friction within the pericardial sac.
Pericardial fluid.
From the right atrium, the deoxygenated blood flows through this valve to the right ventricle.
The tricuspid valve
This is referred to as the relaxation of the heart.
Diastole.
This is the pressure against which the left ventricle must pump blood.
Afterload.
This is caused by 2eakness in the wall of the aorta
Aortic aneurism
The inner lining of chambers of the heart and the surface of the valves
Endocardium
Oxygenated blood flows from the left ventricle to the aorta through this valve.
The aortic valve
This is referred to as contraction of the ventricles and the pumping of blood into the systemic circulation.
Systole.
This is the amount of blood returned to the heart to be pumped out.
Preload
This medication is given to relieve pain of angina by increasing vessels to increase oxygenation to the hypoxic tissue.
