The phrenic arteries

Which vessel type typically has an internal diameter of about 30 μm and has a tunica media comprised of 1-2 layers of smooth muscle cells?

Most of the blood leaving the brain passes through one of the dural sinuses and leaves the skull in one of the ________, descending parallel to the common carotid artery in the neck.

Which condition is described as the formation of lipid deposits in the tunica media associated with damage to the endothelial lining?

The strong pulse that is felt by pressing gently along either side of the trachea usually indicates the location of the

Why do veins have relatively thin walls?

In a fetus, blood from the right atrium can flow freely to the left atrium through the ________, thus bypassing the pulmonary circuit.

What is the advantage of the small diameter of capillaries?

Emanating from the descending thoracic aorta, the vessels that supply blood to the vertebral column area and the body wall are called the
