Explanation:

The definition of an organ system is a "group of organs that work together as a biological system to perform one or more functions". Each organ in a system does a different job in order to achieve the same goal. For example, the stomach breaks down food, and the intestines gather nutrients but the goal of both is to digest food.

explanation:

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
