Intro to the heart
Where the heart is located in the human body.
What is between the lungs?
What is the function of the septum in the heart?
Prevents mixing of oxygenated and deoxygenated blood.
The formula for calculating cardiac output
What is heart rate x stroke volume?
The function of capillaries in the body
What allows for the gas exchanging with tissues?
Which blood vessels carry blood away from the heart?
Arteries
The loop of the human cardiovascular system that carries blood from the heart to the body tissues and back
What is the systemic circuit?
The role of the Inferior Vena Cava in the heart.
What returns blood to heart from lower body?
The function of the epicardium
What is the protective layer of tissue of the heart?
The 3 types of blood vessels
What are veins, arteries, and capillaries?
Why do arteries not have valves?
Due to high pressure the blood only flows that one way.
The blood vessels that supply oxygenated blood to the heart muscle itself.
What are the coronary blood vessels?
Blood vessels that bring oxygenated blood from the lungs
What are the Pulmonary Veins?
The volume of blood pumped out by a ventricle in a heartbeat
What is stroke volume
How veins maintain blood flow under low pressure
What is Muscular Pumping?
Definition of systole
Where ventricles are contracting with all valves closed?
What is the function of the endocardium?
Thin layer lining the heart chambers
Chamber of the heart that receives oxygenated blood from the lungs
What is the Left Atrium?
What is the process of the cardiac cycle?
One contraction and relaxation of the heart muscle
What is the main difference between arteries and veins?
Arteries have high pressure, veins have low pressure
What is the relationship between the heart and the lungs in the circulation of blood?
The heart pumps blood to the lungs for oxygenation
What major blood vessels are attached to the heart in the Systemic Circuit?
Vena cava and Aorta
The function of the atrioventricular (AV) valves in the heart
What regulates blood flow between atria & ventricles?
The relaxation of the heart and filling with blood
What is Diastole?
Which layer of arteries and veins is responsible for muscle thickness?
Tunica Media
Located on top of the heart with three blood vessels sprouting off
Where is the Aorta?
