Chambers
The chamber oxygenated blood enters the heart
What is the left atrium?
The most important vessel
What is the aorta?
Opens to allow blood to flow from the right atrium to the right ventricle. Closes to prevent backflow of (deoxygenated) blood (from the right ventricle) to the right atrium_____
What is Atrioventricular Valve (Tricuspid Valve)?
The term used to describe the heart's movement
What is Myogenic Stimulation?
Reason the left side of the heart bigger than that of the right side
Why is because the left side deals with oxygenated blood being distributed to the entire body versus deoxygenated blood on the right from the body
The chambers that are filled with blood first
What are the atria?
Side of the heart that the pulmonary artery carries blood
Where is the right side?
Opens to allow blood to flow from the right ventricle. Closes to prevent backflow (deoxygenated) blood into the right ventricle (from the pulmonary artery)______
What is Pulmonary Semilunar Valve?
The main purpose of the atrioventricular node (AVN)
Why is to delay impulse from the SAN?
The time between atrial systole and ventricular systole
What is 0.1- 0.2 seconds?
The chamber that has the thickest walls
What is the left ventricle?
The two parts of the vena cava
What are the inferior and superior?
Closes to prevent backflow of blood (from the left ventricle) to the left atrium_______
What is Mitral Valve (Bicuspid Valve)?
Normal muscles are to central nervous systems while the heart is to ___.
What is Sinoartrial Node (SAN)?
The membrane surrounding the heart
What is pericardium?
The chamber that produces blood of the lowest pressure
What is the right atrium?
Reason the pulmonary vein is special
Why is that it is the only vein to carry oxygenated blood to the heart?
Closes to prevent backflow of (oxygenated) blood into the left ventricle from the aorta_____
What is Aortic Valve?
The SAN is considered to be this.
What is pacemaker?
The purpose of the pulmonary trunk
Why is to divide the left and right pulmonary arteries?
Reason for smaller atria than ventricles
Why is the atria pump blood to close body parts while ventricles pump to further body parts?
What is the subclavian artery, coronary artery, or cardiac vein?
A brief summary of the different valves of the mammalian heart

What are the atria?
What is the Purkinje fibres?
