The following is the pathway of blood through the body: 1. blood enters the heart from the body through the superior & inferior vena cava 2. it enters the right atrium and passes through the tricuspid valve into the right ventricle 3. it passes from the right ventricle through the pulmonary valve, pulmonary artery and to the lungs to be oxygenated 4. oxygenated blood returns from the lungs and into the left atrium 5. it passes through the bicuspid valve into the left ventricle 6. it leaves the left ventricle through the aortic valve, into the aorta and out to the rest of the body
The oxygenated blood first enters the capillaries, then they carry the blood through other veins to the rest of the body.
Oxygenated blood enters the kidneys through the renal arteries. Blockage of these arteries can affect kidney function as well as blod pressure.
Through the inferior and superior vena cavaThe left atria of the heart is where oxygenated blood enters, it is then pumped to the left ventricle and then to the rest of the body thru the systematic circuit. The heart is separated by the septum, which separates oxygenated and deoxygenated blood.
Blood becomes oxygenated in the lungs, then the oxygenated blood goes to the heart via the pulmonary veins and enters the left atrium
the air enters the bronchioles, and into the aveoli, which are small, one cell-thick sacks of air. These sacks are surrounded by tiny capillaries, which is how your blood retrieves its oxygen. From here, the oxygenated blood is carried back to the heart through the pulmonary vein and pumped into your body.
Deoxygenated blood enters the right atrium, and passes through the tricuspid valve to the right ventricle. The blood is then pumped through the pulmonary artery to the lungs to become oxygenated. From the lung blood comes through pulmonary veins to the section of the heart called the left atrium. The left atrium pumps to the left ventricle. The left ventricle pumps out through aorta to the rest of the body to deliver the oxygen. Once delivered, it returns to the right atrium to begin the cycle once more.
De-oxygenated blood enters the right atrium from the vena cava and then passes through the tricuspid valve into the right ventricle. It is then sqeezed/pumped through the right semi lunar valve into right pulmonary artery which transports blood to the lungs. Oxygenated blood returns to the heart via pulmonary veins and enters the left atrium, passes through the bicuspid valve to enter the left ventricle which contracts, sqeezing/pumping the oxygenated blood through the left semi lunar valve into the aorta from where it is transported to all the body's cells.
After traveling through the body when blood returns to the heart.The blood first enters the right atrium. It then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle puts pressure on the blood to push it through the pulmonic valve into the pulmonic artery. Next, the pulmonic artery carries blood to the lungs where it "picks up" oxygen, and leaves the lungs and returns to the heart through the pulmonic vein. The blood enters the left atrium, then descends through the mitral valve, into the left ventricle. The left ventricle then pumps blood through the aortic valve, and into the aorta, it is now pushed to the rest of the body.
Oxygenated blood enters the heart in the pulmonary vein. It passes through the left ventricle, before exiting in the aorta.
You're better off with a diagram, but I'll try... Blood enters from the right through the vena cava into the right atrium. The tricuspid valves let it into the right ventricle. From there the semilunar valves let it into the pulmonary artery. From there it goes to the lungs, and returns, oxygenated, in the pulmonary vein, entering on the far left. It goes into the left atrium and then is let into the left ventricle by the bicuspid valves. From there it goes through the semilunar valves to the aorta and from there to the rest of the body.
