Circulation
Blood in the right atrium came from these other structures.
What are the superior and inferior vena cava?
They carry blood away from the heart.
What are arteries?
The upper right of the heart that receives blood from the superior and inferior vena cava.
What is the right atrium?
The valve found between the left atrium and left ventricle.
What is the bicuspid valve?
Movement of blood between the heart and lungs.
What is pulmonary circulation?
Blood from the right ventricle flows into these structures.
What are the pulmonary trunk and pulmonary arteries?
They carry blood toward the heart.
What are veins?
It sends blood through the pulmonary arteries to the lungs when it contracts.
What is the right ventricle?
The location of the SA and AV nodes.
What is the right atrium?
The movement of blood between the heart and the rest of the body.
What is systemic circulation?
This heart chamber is responsible for aortic blood pressure.
What is the left ventricle?
The microscopic blood vessels responsible for exchange of substances with the tissues.
What are capillaries?
It receives blood from the lungs via the pulmonary veins.
What is the left atrium?
The muscular wall that divides the ventricles.
What is the septum?
The p wave represents this in an EKG
What is atrial contraction?
The blood in this chamber came from the lungs.
What is the left atrium?
They carry blood from arteries to capillaries.
What are arterioles?
It sends blood through the aorta to the body when it contracts.
What is the left ventricle?
The nerves that run up the sides of the ventricle.
What are the Purkinje fibers?
This is represented by the QRS complex
What is a ventricular contraction?
These are the only veins to carry oxygenated blood
What are the pulmonary veins?
They drain the blood from capillaries into the veins.
What are venules?
It's the valve that prevents blood from reentering the right atrium when the ventricles contract.
What is the tricuspid valve?
The nerve that carries impulses from the AV node down through the septum and up the Purkinje fibers.
What is the bundle of His?
The blood vessels that supply the heart muscle with oxygen and nutrients.
What are cardiac arteries?
This valve allows deoxygenated blood to flow out of the heart.
What is the pulmonary valve?
The process that exchanges substances between the capillaries and tissues.
What is diffusion?
AV is an abbreviation for this term.
What is atrioventricular?
SA is the abbreviation for this term.
What is sinoatrial?
A graph that shows the electrical impulses that are generated by the heart.
What is an ECG or EKG?
