The circulatory system in humans includes two major circulation pathways: the systemic circulation and the pulmonary circulation. In the systemic circulation, oxygenated blood is pumped by the heart to the body's tissues through arteries, and deoxygenated blood returns to the heart through veins. In the pulmonary circulation, deoxygenated blood is pumped from the heart to the lungs to receive oxygen and then returns to the heart to be pumped out to the body again. |
