Basic Anatomy
This structure separates the two sides of the heart.
Septum
Purpose of the left atrium.
Receives oxygenated blood from lungs.
The systematic circuit does this.
Carries blood from heart to body and back
This layer of the heart is the thickest.
Myocardium
Diastole refers to this.
Relaxation of the heart and filling it with blood.
The four chambers of the heart.
Two atria and two ventricles
The function of valves within the heart.
Prevents blood from flowing backwards
What comes first in the oxygenated blood timeline?
Lungs
The serous pericardium provides this critical function.
Produces lubricating fluid to reduce friction.
The heartbeat is one _____ and _____ of the heart muscle
Contraction;Relaxation
The ____ is pointed towards the left hip
Apex
The superior vena cava returns blood to the heart from this location.
The upper body.
The pulmonary circuit does this.
Carries blood from heart to lungs and back.
Inflammation of the pericardium.
Pericarditis.
A normal, healthy blood pressure is considered to be.
Equal or less than 120/80.
Describe the base of the heart.
The superior posterior surface.
Deoxygenated low pressure blood is kept from back-flowing thanks to this structure?
Venous Valves
The two loops that circulate blood back to the heart.
Pulmonary circuit and the systematic circuit
The visceral pericardium is also known as what?
Epicardium
During rest, the average the heart beats this many times in one minute.
75 times per minute at rest
The location of the aorta.
The aorta extends upward from the left ventricle, forming an arch before descending down through the chest and abdomen.
The right AV valve is held in place by these structures.
Chordae tendneae
Blood is supplied to the myocardium via these 2 structures.
Right and Left Coronary Arteries
Coronary artery disease affects the heart in this way.
Reduces blood flow and oxygen to the myocardium (muscle layer) due to narrowed arteries.
Systole refers to this.
Contraction of the heart
