The heart pumps blood throughout the body, the kidneys filter waste and flush urine out, and skeletal muscles allow for movement like swinging a bat.
The systemic veins and heart transfer waste-filled blood from the tissues into the pulmonary circulattion. The sytsemic veins bring waste-filled blood to the right atrium, which pumps it into the right ventricle, which pumps it into the pulmonary circulation.
The heart is the main organ that pumps and transports blood in the body. It contracts to push blood through the circulatory system, delivering oxygen and nutrients to tissues and carrying waste products away. Arteries and veins help transport blood to and from the heart throughout the body.
The heart and lungs rely heavily on blood, a liquid connective tissue, to carry out their function. The heart pumps the oxygen-containing blood throughout the body. The blood picks up oxygen at the alveoli of the lungs.
