DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.
The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs. In the human heart there is one atrium and one ventricle for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle.
The ventricles of the heart function to pump blood to the entire body. Right ventricle: receives blood from the right atrium and pumps it to the pulmonary artery (to lungs). â¦ Left ventricle: receives blood from left atrium and pumps to aorta (to rest of body). Hoped this helped byee!!
