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
