What returns blood to heart?
The veins return blood from the body back to the heart, then out of the heart to the lungs where it is oxygenated, then back to the heart and carried back out into the body by arteries. The blood in the veins is blue but is seen through you skin as a dark green.
What are the 3 main vessels of the heart?
There are actually four valves in the heart: The tricuspid valve, mitral valve, pulmonary semilunar valve, and aortic semilunar valve. If you needed to list three different types of valves, you could consider both semilunar valves as one configuration type. Then you would have: Tricuspid valve, bicuspid (aka mitral) valve, and semilunar valves.
What 2 jobs do the valves of the heart do?
Both AV valves, the bicuspid and tricuspid, (separating the ventricles from the atria) prevent blood from flowing back into the atria when the ventricles contract. Both the semilunar valves (separating the arteries from the ventricles) prevent blood from flowing back from the arteries once it has been pumped out of he ventricles, and thus, out of the heart. The difference is that the AV valves are contracted when they are CLOSED, but the semilunar valves are contracted when OPEN. Otherwise, I can't think of another major job besides preventing backflow.
Where is the manual fuel pump on a 85 Honda prelude dual carb located?
The main electric fuel pump is located just forward of the left rear wheel under the car. There is also two small electric fuel shutoff solenoid valves located on the carbs. One valve on each carb. Even if the main pump is working, if the carb solenoid valves are inop, no fuel will go to the carbs.
What does the function of the heart valves?
Heart valves control the flow of blood into, out of, and within the chambers of the heart. The main function is to let blood flow in one direction only, ensuring that blood does not flow backwards.

What were the two main problems caused by using valves in colossus?
Reliability and heat were the main problems. Valves were fragile devices that, due to the relatively primitive way they were manufactured, failed pretty quickly. In addition to that, they gave off vast amounts of heat. This meant they needed expensive air-conditioning systems to keep their temperature down.
