A&P II - Unit 3: Coronary Circulation, Blood flow, Electrical

What is the function of the coronary arteries?

• To supply oxygen-rich blood to the heart muscle
• To filter waste products
• To aid in digestion
• To regulate body temperature

Where is the circumflex artery?

• Branch of the right coronary artery
• Branch of the pulmonary artery
• Located in the brain
• Branch of the left coronary artery

What is the function of the interventricular arteries?

• Supply blood to the walls of the atria of the heart
• Regulate blood pressure in the heart
• Aid in the conduction of electrical impulses in the heart
• Supply blood to the walls of the ventricles of the heart

Where is the great cardiac vein?

• On the posterior surface of the heart, alongside the interventricular sulcus.
• Adjacent to the pulmonary artery
• Underneath the aorta
• In the left atrium

Where is the middle cardiac vein?

• Posterior surface of the heart, in the posterior interventricular sulcus
• Right atrium, near the coronary sinus
• Anterior surface of the heart, in the anterior interventricular sulcus
• Left ventricle, in the coronary sulcus

Where does the small cardiac vein supply blood?

• left ventricle
• right atrium
• pulmonary artery
• aorta

What is the cardiac cycle?

• Sequence of events during one heartbeat
• A type of heart surgery
• A method of measuring blood pressure
• A term used to describe heart rate

What are hearts sounds?

• Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it.
• Heart sounds are the vibrations of the brain
• Heart sounds are the sounds produced by the lungs
• Heart sounds are the result of stomach digestion

What is the systemic circuit?

• The systemic circuit is the pathway that carries blood from the heart to the liver and back to the heart.
• The systemic circuit is the pathway that carries blood from the heart to the brain and back to the heart.
• The systemic circuit is the pathway that carries blood from the lungs to the heart.
• The systemic circuit is the pathway that carries blood from the heart to the body and back to the heart.

What is the pulmonary circuit?

• The pulmonary circuit is the pathway that carries air between the heart and the lungs.
• The pulmonary circuit is the pathway that carries blood between the lungs and the liver.
• The pulmonary circuit is the pathway that carries blood between the heart and the brain.
• The pulmonary circuit is the pathway that carries blood between the heart and the lungs.
