Blood Vessels & Heart Flashcards
Tunica media
Smooth muscles and fibers
Vasodilation and vasoconstriction
Elastic fibers
Yellow with age
Tunica adventitia
Dense irregular Connective tissue with collagen fibers and elastic fibers
Vasa Vasorum
Blood vessels of blood vessels
Supply exterior of wall with oxygen and nutrients for the inferior of blood vessel
Conducting/elastic arteries
Aorta and big arteries
Stretch and hold high blood pressure
Distributing/Muscular arteries
After conducting arteries
Thinner tunica media
Internal elastic lamina bumpy layer
Less elastin, more smooth muscle cells
Thrombus
Blood clot
Sclerosis
Hardening
Occlusion
Blood clot
Endocardium
Tunica intima
Myocardium
Tunica media
Pericardium
Tunica adventitia
Tunica intima
Simple squamous layer
Elastic layer
Some collagen and elastin. No elastic lamina
Pericarditis
Symptoms: substernal or left chest pain, relieved by sitting up or bending forward, worsened by lying down or inspiration
Dry cough, fever
Interatrial septum
Partitions atria
Fossa ovalis
Remnant of fetal FOramen ovale
