what happens if pulmonary veins bring deoxygenated blood to heart?
Answers
Anatomy of the Heart
The heart is an organ responsible for pumping blood through the blood vessels using rhythmic contractions of cardiac muscle.
The human heart is the pump for the circulatory system, and along with the circulatory system is considered to be an organ of the cardiovascular system. It consists of four chambers and pumps blood through both systemic and pulmonary circulation to enable gas exchange and tissue oxygenation. The heart is located in the thoracic cavity between the lungs and protected by the rib cage.
Structure of the Heart
The heart consists of four chambers separated into two sides. Each side contains an atria which receives blood into the heart and flows it into a ventricle, which pumps the blood out of the heart. The atria and ventricle on each side of the heart are linked together by valves that prevent backflow of blood. The wall that separates the left and right side of the heart is called the septum.
