Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium. Atrial contraction:blood flows from your right atrium into your right ventricle through the open tricuspid valve.When the ventricles are full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze). Atrial contraction: blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricles are full, the mitral valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze.) Ventricular contraction: blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs.Ventricular contraction: blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated over and over, causing blood to flow continuously to the heart, lungs and body.
Blood flows through the following basic structures of the heart:
First, the Superior, and inferior vena cava take the "blue" blood to the right atrium. Next, the right atrium pumps the blood through a valve to the right ventricle. the right ventricle pumps the blood through another valve to the pulmonary artery. Then the pulmonary Artery sends the "blue" blood off to the alveoli. The alveoli are tiny air sacs within the lungs. In the alveoli, gas exchange happens that is called diffusion. Oxygen into the blood, and carbon dioxide to the alveoli to be exhaled. The blood then Travels to the Pulmonary vein, through a valve, to the left atrium. Next, the left Atrium pumps the blood through another valve to the left ventricle. Last, the "red" blood travels to the largest blood vessel in the body, which is the Aorta. Then the blood is sent to the entire body, where it comes back to the heart later, to repeat the process's.
Venous blood enters into the right atrium, empties into the right ventricle through the tricuspid valve. from the left ventricle, blood flows through the pulmonary artery to the lungs where CO2/O2 gas exchange takes place. Oxygenated blood flows to the left atrium into the left ventricle through the mitral valve. From the left ventricle, blood is pumped out through the aortic valve, into the aorta where blood then enters the systemic circulation.
venous blood goes up to the lungs in order to get oxygized
right atrium.
A valve
it doesn't
You get deoxygenated or impure blood from the whole body. It enters the right atrium. Right atrium pumps the blood in right ventricle. From right ventricle blood goes to your lungs. Here the blood gets oxygenated or get purified. Then it enters your left atrium. Left atrium pumps the blood in left ventricle. Left ventricle pumps the blood to your whole body.
When it leaves the left atrium, blood passes through the tricuspid valve into the left ventricle.
The right ventricle pumps blood to the lungs where the alveoli oxygenate the blood. Then the blood comes back through the pulmonary veins, and into the left atrium, through the valve to the ventricle, to the pulmonary artery, and to the different parts of the body.
It comes from the left ventricle out through the aorta.
Because blood travels directly from the left atrium to the left ventricle.
The left ventricle receives blood from the left atrium through the mitral valve.
Blood enters the left ventricle from the left atrium by passing through the mitral valve. The mitral valve functions to prevent blood from flowing back into the left atrium when the left ventricle contracts.
left ventricle Blood enters the left & right atria. Blood entering the left ventricle came from the left atrium. Blood from the body enters the right atrium. From there it is pumped to the right ventricle, through the lungs, to the left atrium, to the left ventricle, then throughout the body. Then back to the right atrium...
Blood enters the left atrium through the pulmonary veins, and is pumped into the left ventricle through the mitral valve.
As deoxygenated blood returns from the body, it flows from the vena cava into the right atrium. From the right atrium the blood flows into the right ventricle which pumps the blood through the pulmonary artery to the lungs. Oxygenated blood returns from the lungs via the pulmonary vein and enters the left atrium. The left atrium empties into the left ventricle which pumps the blood through the aorta and to the body.
You get deoxygenated or impure blood from the whole body. It enters the right atrium. Right atrium pumps the blood in right ventricle. From right ventricle blood goes to your lungs. Here the blood gets oxygenated or get purified. Then it enters your left atrium. Left atrium pumps the blood in left ventricle. Left ventricle pumps the blood to your whole body.
When it leaves the left atrium, blood passes through the tricuspid valve into the left ventricle.
The right ventricle pumps blood to the lungs where the alveoli oxygenate the blood. Then the blood comes back through the pulmonary veins, and into the left atrium, through the valve to the ventricle, to the pulmonary artery, and to the different parts of the body.
LEFT ATRIUM > Left ventricle > Aorta > rest of the body
Oxygen goes from the muscles to the right atrium, from there it goes to the right ventricle and into the lungs then it passes from the lungs to through the left atrium and into the left ventricle where it is recirculated through the body.
It comes from the left ventricle out through the aorta.
