The vital importance of the heart is obvious. Trace the pathway of oxygenated and deoxygenated blood thorough the chambers of the heart.Identify the veins and arteries of the coronary circulation system.Compare systemic circulation to pulmonary circulation.
Relate the structure of the heart to its function as a pump.Identify the tissue layers of the heart.Describe the internal and external anatomy of the heart.Describe the location and position of the heart within the body cavity.
There are 10 questions in total.By the end of this section, you will be able to: Summary Quiz Identify the part of the heart indicated by an arrow. The semi-lunar valves prevent backflow of blood from the arteries into the ventricles Aortic semi-lunar valve Pulmonary semi-lunar valve The aorta carries the oxygenated from the left ventricle to the rest of the body Aortic arch AortaĪtrio-ventricular valves prevent backflow of blood into the atria when ventricles contract Tricuspid valves Bicuspid valve (mitral valve) Tendon The left ventricle pumps oxygenated blood to the body via the aorta Left ventricle The left atrium collects the oxygenated blood and pumps it to the left ventricle Left atrium The pulmonary veins carry oxygenated blood from the lungs to the left atrium Pulmonary veins
The septum separates the left and right sides of the heart septum The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs Pulmonary Artery The right ventricle pumps deoxygenated blood to the lungs right ventricle The right atrium collects deoxygenated blood and pumps it to the right ventricle right atrium The vena cava carries deoxygenated blood from the body to the right atrium superior vena cava (transports blood from the head) inferior vena cava (transports blood from rest of body) Blood travels through the heart twice before returning to the body The double circulatory systemĮxternal view of the heart superior vena cava pulmonary artery aorta pulmonary vein pulmonary vein coronary artery right atrium left ventricle inferior vena cava right ventricle
