100

These vessels carry blood away from the heart.

What are arteries?

100

This circuit carries blood between the heart and lungs.

What is pulmonary circulation?

100

This is the largest artery in the body.

What is the aorta?

100

These structures prevent backflow of blood in veins.

What are valves?

100

This number represents ventricular contraction during a blood pressure reading.

What is systolic pressure?

100

This disorder involves elevated blood pressure

What is hypertension?

200

These tiny vessels allow exchange of oxygen, nutrients, and wastes.

What are capillaries?

200

This circuit carries blood between the heart and body tissues.

What is systemic circulation?

200

Name the first section of the aorta.

What is the ascending aorta?

200

Blood from the lower body returns to the heart through this large vein.

What is the inferior vena cava?

200

his number represents ventricular relaxation during a blood pressure reading.

What is diastolic pressure?

200

This disorder results from plaque buildup in arteries.

What is atherosclerosis?

300

These vessels control blood flow into capillary beds and play a major role in blood pressure regulation.

What are arterioles?

300

Blood leaving the right ventricle enters this circuit.

What is the pulmonary circuit?

300

This section of the aorta contains the brachiocephalic trunk, left common carotid, and left subclavian artery.

What is the aortic arch?

300

Blood from the head, neck, and upper limbs returns through this vein.

What is the superior vena cava?

300

This feedback system helps regulate blood pressure through baroreceptors.

What is a negative feedback loop?

300

This disorder causes enlarged, twisted superficial veins.

What are varicose veins?

400

These vessels collect blood from capillaries and begin the return trip to the heart.

What are venules?

400

Blood returning from the body enters this chamber first.

What is the right atrium?

400

The abdominal aorta divides into these two large arteries.

What are the common iliac arteries?

400

These veins are closer to the skin and commonly develop varicose veins.

What are superficial veins?

400

Name one factor that can increase blood pressure.

Increased blood volume, increased viscosity, or decreased vessel compliance

400

This disorder involves a blood clot in a deep vein.

What is deep vein thrombosis (DVT)?

500

Name all five types of blood vessels in order of blood flow.

What are arteries, arterioles, capillaries, venules, and veins?

500

Trace the pathway of blood from the left ventricle to the body and back to the right atrium.

Left ventricle → aorta → body tissues → vena cava → right atrium

500

Name the four sections of the aorta.

Ascending aorta, aortic arch, thoracic aorta, abdominal aorta

500

Two adaptations of veins that help blood return to the heart despite low pressure.

What are valves and the skeletal muscle pump?
(Accept respiratory pump as one of the adaptations.)

500

Which blood vessels have the greatest role in adjusting blood pressure?

What are arterioles?

500

This disorder causes leg pain during exercise because of reduced arterial blood flow.

What is peripheral artery disease (PAD)?
