Sinusoid
Vessel that takes blood from the fetal pulmonary artery to the aorta
Ductus Arteriosus
A sac that forms a weak spot in an arterial wall
Aneurysm
The lining of an artery or vein

Renin
Sphincter that regulates blood flow into a capillary network
Precapillary Sphincter
A small artery
Arteriole
The pressure that pulls tissue fluid into capillaries
Colloid Osmotic Pressure
The pressure that forms tissue fluid from the plasma in capillaries
Filtration Pressure
Circulation pathway that allows the liver to regulate the contents of the blood
Hepatic Portal
Circulatory shock that is the result of bacterial infection
