Circulation Pathways

The superior vena cava is formed by the merging of the _______ veins.

brachiocephalic

The artery that bifurcates into the right subclavian artery and the right common carotid artery is the

brachiocephalic artery

The left atrium and left ventricle are part of which circuit of the cardiovascular system?

systemic circuit

Which circuit of the cardiovascular system is responsible for sending blood to the kidneys, stomach, and pelvic regions?

systemic circuit

The inferior mesenteric artery supplies blood to the

transverse colon, descending colon, sigmoid colon, and rectum

Typically, there are _____ left and _____ right pulmonary veins to carry the oxygenated blood to the left atrium.

two, two

Pulmonary arteries carry highly oxygenated blood.

False Pulmonary arteries travel to the lung to take up oxygen, so the blood traveling back to the heart from the lungs in the pulmonary veins carries the oxygenated blood.

Which of the cardiovascular system's circuits has deoxygenated blood in its arteries?

Pulmonary circuit

Pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs.

True

The left suprarenal and gonadal veins differ from the right suprarenal and gonadal veins in how directly they get to the inferior vena cava.

True

The stomach needs the celiac artery blood supply in order to receive blood.

True

The artery pair that supplies the lower limbs are the

external iliac arteries

As a venous pathway moves closer to the heart, the veins

get larger

Which carries blood from the liver to the inferior vena cava?

hepatic veins

The primary arterial supply to the pelvis and perineum is from the internal ___________ artery.

iliac

The left renal vein, right renal vein, right suprarenal vein, and right gonadal vein merge directly into the

inferior vena cava

The brachiocephalic veins are formed by the

internal jugular veins and subclavian veins

The branches that arise from the celiac trunk are the

left gastric, splenic, and common hepatic arteries.

In the pulmonary circuit, blood leaves the ________ to pass through the lungs, then returns to the heart by entering the ________.

right ventricle; left atrium

The azygos vein merges with the _____________ vena cava.

superior

The right and left brachiocephalic veins merge to form the _____________ vena cava.

superior

The artery that arises from the descending aorta and is immediately inferior to the celiac trunk is the _____ artery.

superior mesenteric
