hi, this is one question in a test, i might post more.
in the heart blood flows from the right atrium to the right ventricle where it is pumped to the...?
What? I'm pretty sure this is easy, i'm just stumped-_-
is it lungs?
im nit even kidding you copyed and pasted from either wikipedia or google
The answer to your question is the pulmonary artery. To understand how blood flows through the heart, it's important to know the basic anatomy and function of the heart.
1. The heart has four chambers: two atria (left atrium and right atrium) and two ventricles (left ventricle and right ventricle).
2. Deoxygenated blood, which is low in oxygen and high in carbon dioxide, enters the heart through the superior and inferior vena cava and flows into the right atrium.
3. From the right atrium, the blood moves into the right ventricle through the tricuspid valve, which prevents backflow of blood.
4. The right ventricle then contracts, pumping the deoxygenated blood out through the pulmonary valve and into the pulmonary artery.
5. The pulmonary artery carries the deoxygenated blood to the lungs, where it picks up oxygen and releases carbon dioxide through the process of respiration.
So, in summary, the blood flows from the right atrium to the right ventricle and then gets pumped to the pulmonary artery, which transports it to the lungs for oxygenation.
ach side of your heart uses an inlet valve to help move blood between the atrium and ventricle. The tricuspid valve does this between the right atrium and ventricle. The mitral valve does this between the left atrium and ventricle. The "lub" is the sound of the tricuspid and mitral valves closing.
Each of your heart's ventricles has an outlet valve. The right ventricle uses the pulmonary valve to help move blood into the pulmonary arteries. The left ventricle uses the aortic valve to do the same for the aorta. The "DUB" is the sound of the aortic and pulmonary valves closing.
Each heartbeat has two basic parts: diastole (di-AS-toe-lee), or relaxation, and atrial and ventricular systole (SIS-toe-lee), or contraction.
During diastole, the atria and ventricles of your heart relax and begin to fill with blood. At the end of diastole, your heart's atria contract (atrial systole) and pump blood into the ventricles. The atria then begin to relax. Next, your heart's ventricles contract (ventricular systole) and pump blood out of your heart.
