Blood vessels made up of three layers: Outermost = tunica adventitia, middle = tunica media, inner = tunica intima.
Tunica adventitia made up of connective tissue.
Systolic pressure = blood moving out of heart, contraction. Diastolic = heart filling with blood.
Aneurysm = bulge in blood vessel, can lead to severe hemorrhaging.
Capillaries branch off from metarterioles. Sphincters control blood flow to capillary bed.
Formation of new capillary beds = angiogenesis. Facilitated by pericytes.
Biscuspid valves in veins open/close in response to blood pressure.
Sinuses located in liver/spleen/brain.
Varicose veins caused by backflow of blood in veins.
