CV System Flashcards
Main Purpose of CV System
Transports oxygen, nutrients, cell waste, and vital substances to maintain homeostasis
Apex of Heart
Pointed Inferior end of Heart
Base
Broader Superior Portion of Heart
Pericardium
Double sac of serous membrane that encloses the heart
Epicardium
Part of heart wall that hugs the external surface of the heart (inferior to Pericardium)
Parietal Pericardium
Loosely applied protection that anchors the heart to surrounding structures
Myocardium
Thick bundles of Cardiac muscle that are twisted and whorled into ringlike arrangments
Endocardium
Endothelium that lines the heart chambers
Atria
Superior chambers that receive but do not pump blood.
Ventricles
Inferior chambers that pump blood when contracting
- Right ventricle forms majority of anterior surface
- Left ventricle forms the apex
Ischemic Stroke
Homeostatic Imbalance caused by buildup of atherosclerosis blood clot that prevents blood entering the brain
Heart Attack
Homeostatic Imbalance caused by the buildup of atherosclerosis. A blood clot forms that then blocks flow to the heart
Coronary Artery Disease
Homeostatic Imbalance caused by buildup of atherosclerosis to heart.
Difference between Veins and Arteries
Veins move blood toward heart
Arteries move blood away heart
Name of Valves
Triospoid Valve
Pulmonic Valve
Mitral Valve
Aortic Valve
