Anatomy and Physiology- The Cardiovascular System | Questions and Answers with complete solution

Main Function of the Cardiovascular System - Transports blood throughout our body. Blood carries oxygen, nutrients, cell wastes, hormones, and other substances. Atria - -The chambers at the top of the heart. -They receive blood returning to the heart. -They contact and force blood into the ventricles that lay below them. -Separated by a septum Right Atrium - Receives DEOXYGENATED blood from the BODY via the SUPERIOR AND INTERIOR VENA CAVAE. Left Atrium - Receives OXYGENATED blood from the LUNGS via the PULMONARY VEINS. Ventricles - -The chambers at the bottom of the heart. -They pump blood away from the heart, to the lungs/body. -They contract and force blood into the blood vessels -Separated by a septum Right Ventricle - Pumps DEOXYGENATED blood to the LUNGS via the PULMONARY ARTERIES. Left Ventricle - Pumps OXYGENATED blood to the BODY via the AORTA Valves - Function to prevent the backwards flow of blood through heart circulation. AV (atrioventricular) Valves - Valves that have Chordae Tendinae tendons that open and shut the valves. They are attached to leaflets (valve flaps) and are anchored to the epicardium covering the capillary muscles.Tricuspid Valve - Separates right atrium from right ventricle An atrioventricular (AV) valve
