Correction pls that’s why comments are not allowed : Impure blood will come in RIGHT auricle (not left auricle shown in video). Hope U will now correct the left versus right side. Blood will go to whole body from LEFT ventricle through Aorta. Ok students Pls correct it. Sorry for the inconvenience cost to u. Thanks Cardiovascular System is responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body. The cardiovascular system is powered by the body’s toughest working organs : the heart & the lungs. Two primary circulatory loops in the human body are – 1. Pulmonary circulation : transports deoxygenated blood from the right side of the heart to the lungs, where the blood picks up oxygen and returns to the left side of the heart. The pumping chambers of the heart that support the pulmonary circulation loop are the right atrium and right ventricle. 2. Systemic circulation : carries highly oxygenated blood from the left side of the heart to all of the tissues of the body (with the exception of the heart and lungs). Systemic circulation removes wastes from body tissues and returns deoxygenated blood to the right side of the heart. The left atrium and left ventricle of the heart are the pumping chambers for the systemic circulation loop. The average human body contains about 4 to 5 liters of blood. As a liquid connective tissue, it transports many substances through the body and helps to maintain homeostasis of nutrients, wastes, and gases. Blood is made up of red blood cells, white blood cells, platelets, and liquid plasma
