Heart Function

The heart is divided into two sides, right and left, with no connection between them
Blood flow is kept separate on each side of the heart
Deoxygenated blood enters the heart through the superior and inferior vena cavae
The blood passes through the right atrium and into the right ventricle
The right ventricle pumps the blood through the pulmonary valve into the pulmonary arteries
The pulmonary arteries carry the blood to the lungs where it becomes oxygenated
Oxygenated blood then travels through the pulmonary veins into the left atrium
The left atrium pumps the blood through the bicuspid valve into the left ventricle
The left ventricle pumps blood through the aortic valve into the aorta which distributes the blood throughout the body
The left ventricle has the thickest myocardium because it is stronger than the right ventricle. This is because the left ventricle is responsible for pumping blood throughout the entire body while the right ventricle only pumps to the lungs
Coronary circulation is the process of delivering oxygenated blood to the myocardium
Coronary arteries deliver oxygenated blood to the myocardium
Pulmonary circulation occurs on the right side of the heart and sends unoxygenated blood to the lungs to become oxygenated
Systemic circulation occurs on the left side of the heart and pumps oxygenated blood throughout the body
Angina and Myocardial Infarction (heart attack) are conditions that affect the heart’s blood supply

Description

Test your knowledge on how the heart functions, including the flow of deoxygenated and oxygenated blood. Explore the roles of the right and left sides of the heart, heart valves, and the significance of the left ventricle. This quiz will reinforce your understanding of cardiovascular physiology.
