The blood goes back to the heart to get oxygen.
tricuspid valve
Very poorly. Let's consider the left side of the heart which pumps blood into the aorta, the main artery leading from the heart. At the peak of a contraction (squeeze) of the heart it pumps blood into the aorta. The aorta is very elastic and expands as the squeeze of the heart pushes blood into it. Some of the blood, of course, continues on, and under normal circumstances, the aortic valve then closes, and as the heart fills with blood for the next squeeze, the elasticity of the aorta shrinks the aorta and pumps more blood into the body. If the valve is damaged (or, in your question, absent) then as the aorta's elasticity shrinks it, the blood would be forced back into the heart, not letting new blood come in to be pumped out on the next contraction. Thus the pumping would become very inefficient. It is exactly because of damage like this (aortic insufficiency) that the valve sometimes has to be replaced.
One is the heart pumping blood out, into the body. The second is the heart's intake beat; moving more blood into itself for the next pump. The intake is at less pressure than the pump out, so it is less strain on the muscle and sounds lighter.
The heart has two main valves..the one on the right is called the tricuspid valve and the one on the left side of the heart is called the mitral valve. The valves are located between the atria and the ventricles. There are four chambers in the human heart...a right and a left atrium and a right and a left ventricle. The heart is made of "filling stations" = the atria and "pumping stations" = the ventricles. The valves prevent blood from moving between the atria and ventricles during the pumping and filling processes. Once the atria are filled, the next beat of the heart moves the blood to the next chamber....either the right/left ventricle during systole (siss-toll-ee) or diastole (dye-ah-stoll-ee) The top number ( the "numerator") on your blood pressure reading is systolic pressure. The bottom number (the "denominator") is diastolic pressure, which indicates if you have hypertension. Without the valves, the blood doesn't stay in the proper chamber during an action of the heart muscle.
Blood comes into your heart through the veins all throughout the body, it enters the heart through the superior and inferior vena cava, leaves the heart though the pulmonary artery, enters the lungs, gets oxygen, enters the heart again through the pulmonary veins, and then leaves the heart and goes back throughout the body through the aorta. So blood travels from the heart, to the lungs, back to the heart, than out the heart and all through the body.

two things that are next to the heart are veins and blood because veins are coming out of the heart and blood goes through the heart
so there are veins that connect the lungs and the heart and blood vessels carry blood form any direction in and out of the pumping heart
Yes
My friend sitting next to me says it is the vegan aeorta.
A tadpole's circulatory system has one loop and a 2 chamber heart. Oxygen-poor blood goes to the heart from the blood vessels in the body. Then the oxygen-poor blood goes up from the heart through blood vessels in the lungs. Next it comes out as oxygen-rich blood and goes back to the heart. Finally the oxygen-rich blood goes into the blood vessels in the body.

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.
