Me fast you (: as scientists have investigated evolution from a variety of fields, they have found that some of darwin's original ideas were inaccurate or incomplete. the explanation provided by evolution was updated each time to reflect the new information they found. what does this suggest about the theory of evolution? a it has become a stronger and clearer theory as new information is collected b scientists are getting closer to proving evolution to be true so it could be called a law. c. the idea of evolution must be false if scientists have had to make changes to darwins ideas d it has become less trustworthy theroy as changes have been made to it.

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.
