Blood Vessel Types
These vessels carry blood away from the heart.
What are arteries?
This circuit carries blood between the heart and lungs.
What is pulmonary circulation?
This is the largest artery in the body.
What is the aorta?
These structures prevent backflow of blood in veins.
What are valves?
This number represents ventricular contraction during a blood pressure reading.
What is systolic pressure?
This disorder involves elevated blood pressure
What is hypertension?
These tiny vessels allow exchange of oxygen, nutrients, and wastes.
What are capillaries?
This circuit carries blood between the heart and body tissues.
What is systemic circulation?
Name the first section of the aorta.
What is the ascending aorta?
Blood from the lower body returns to the heart through this large vein.
What is the inferior vena cava?
his number represents ventricular relaxation during a blood pressure reading.
What is diastolic pressure?
This disorder results from plaque buildup in arteries.
What is atherosclerosis?
These vessels control blood flow into capillary beds and play a major role in blood pressure regulation.
What are arterioles?
Blood leaving the right ventricle enters this circuit.
What is the pulmonary circuit?
This section of the aorta contains the brachiocephalic trunk, left common carotid, and left subclavian artery.
What is the aortic arch?
Blood from the head, neck, and upper limbs returns through this vein.
What is the superior vena cava?
This feedback system helps regulate blood pressure through baroreceptors.
What is a negative feedback loop?
This disorder causes enlarged, twisted superficial veins.
What are varicose veins?
These vessels collect blood from capillaries and begin the return trip to the heart.
What are venules?
Blood returning from the body enters this chamber first.
What is the right atrium?
The abdominal aorta divides into these two large arteries.
What are the common iliac arteries?
These veins are closer to the skin and commonly develop varicose veins.
What are superficial veins?
Name one factor that can increase blood pressure.
Increased blood volume, increased viscosity, or decreased vessel compliance
This disorder involves a blood clot in a deep vein.
What is deep vein thrombosis (DVT)?
Name all five types of blood vessels in order of blood flow.
What are arteries, arterioles, capillaries, venules, and veins?
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
Name the four sections of the aorta.
Ascending aorta, aortic arch, thoracic aorta, abdominal aorta
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.)
Which blood vessels have the greatest role in adjusting blood pressure?
What are arterioles?
This disorder causes leg pain during exercise because of reduced arterial blood flow.
What is peripheral artery disease (PAD)?
