It goes into the pulmonary arteries. Then on to the lungs. Then into the pulmonary veins. Left atrium then ventricle. Then aorta and its 3 major branching arteries. Then to the abdominal aorta. All turn into veins which lead back to the heart.

Right ventricle
The blood then flows into to the right ventricle, and out into the pulmonary artery through the pulmonic valve.
In the mammalian (and avian) heart, blood passes directly from the atria into the corresponding ventricles. So blood from the right atrium next enters the right ventricle.
The heart is divided into four chambers, the right atrium and the right ventricle, and the left atrium and the left ventricle. Blood that is oxygen poor and high in carbon dioxide enters the heart through the right atrium and is then pumped out to go to the lungs via the right ventricle. The left atrium then pumps the newly oxygenated blood into the left ventricle, which then sends the blood to all parts of the body. So, in short, the right ventricle pumps oxygen poor blood to the lungs and the left ventricle pumps oxygen rich blood to the whole body.
All mammals (monotremes, marsupials, and placental mammals) have the same heart structure: a four chambered heart. The four chambers are the left atrium, the left ventricle, the right atrium, and the right ventricle. The right atrium receives deoxygenated blood from the veins. It pumps it into the right ventricle. The right ventricle pumps it into the pulmonary arteries, which go to the lungs. The lungs have received oxygen and give it to the blood coming through. The now oxygenated blood flows back to the heart by pulmonary veins, and is received by the left atrium. The left atrium pumps the oxygenated blood into the left ventricle. The left ventricle pumps the blood to all of the body through arteries.
the blood flow from the right atrium to the right ventricle trought the tricuspid valve.
Like all mammals, a saber toothed tiger had a four chambered heart. The chambers were the right atrium and the right ventricle, and the left atrium and the left ventricle. Blood that was oxygen poor and high in carbon dioxide entered the heart through the right atrium and was then pumped out to go to the lungs via the right ventricle. The left atrium then pumped the newly oxygenated blood into the left ventricle, which then sent the blood to all parts of the body. So, in short, the right ventricle pumped oxygen poor blood to the lungs and the left ventricle pumped oxygen rich blood to the whole body of the saber toothed cat.
Magically.
The left ventricle receives oxygenated blood from the left atrium. Blood flows from the left atrium through the mitral valve into the left ventricle, which then pumps the blood out into the aorta to supply the body.
