Blood Vessels: Chapter 18

An obstruction in the inferior vena cava would hamper the return of blood from the

Abdomen and pelvis

Which statement best describes arteries?

All carry blood away from the heart

All arteries of systemic circulation branch from the

Aorta

The branch of the umbilical vein in the fetus that connects with the inferior vena cava, bypassing the liver, is the

Ductus venosus

Permitting the exchange of nutrients and gases between the blood and tissue cells is the primary function of

Capillaries

The arterial system that supplies the brain with blood is the

Cerebral arterial Circle (circle of Willis)

Aortic Branch that supplies the head and associated structures

Common carotid

Arteries supplying the heart

Coronary

First branch off of the arch of the aorta

Brachiocephalic

The opening in the septum between the right and left atria of a fetus is called the

Foramen ovale

Longest vein in the body

Great saphenous

The circulatory route that runs from the gastrointestinal tract to the liver is called

Hepatic portal circulation

In hepatic portal circulation, blood is eventually returned to the inferior vena cava through the

Hepatic veins

Artery that supplies a major part of the large intestine and rectum

Inferior mesenteric

Vessel into which veins of the abdomen, pelvis, and lower limbs enter

Inferior vena cava

Which of the following statements about systemic circulation is NOT correct?

It involves the flow of blood from the body to the left atrium

Vein that drains the head and associated structures

Jugular

If a thrombus in the left common iliac vein dislodged, into which arteriole system would it first find it's way?

Lungs

If a vein must be punctured for an injection, transfusion, or removal of a blood sample, the likely site would be the

Median cubital

Vein just behind the knee

Popliteal

A thrombus in the first branch of the arch of the aorta would affect the flow of blood to the

Right side of the head and neck and right upper limb

Which of the following are involved in pulmonary circulation?

Right ventricle, pulmonary artery, and left atrium

Artery that distributes blood to the small intestine and part of the large intestine

Superior mesenteric

Vessel into which veins of the head and neck, upper limbs, and thorax enter

Superior vena cava

The largest of the circulatory routes is

Systemic

Which statement is NOT true of veins?

They always carry deoxygenated blood

Which coat of an artery contains endothelium?

Tunica interna

The greatest amount of elastic tissue found in the arteries is located in which coat?

Tunica media

In fetal circulation, the blood containing the highest amount of oxygen is found in the

Umbilical vein
