you did not let us know how much detail you need. There is a whole lot of information, some of it, not needed for a high school student, but critical if you are a med school student.
Start with the heart having 4 chambers. The right Atrium, which receives blood from the body mostly via the inferior and superior Vena cava. From there it goes to the left ventricle, then to the lungs for gas exchange. From the lungs to the left Atrium, then the left ventricle, to the Aorta and the rest of the body. There is much more to it, but I don't know if you need it. If you do, use a search engine to look up SA node, purkinje fibers

right atrium and ventricle contains deoxygenated blood.
vena cavas transport deoxygenated blood from the body, and pulmonary artery transports deoxygenated blood to the lungs.
left atrium and ventricle contains oxygenated blood.
pulmonary vein transports oxygenated blood from the lungs, and aorta transports oxygenated blood to the body.
the above is the cycle of double circulation of blood in mammals.
