Two valves


What is the wall that stops the blood from flowing back to the Heat?

The heart has one-way valves that prevent blood from flowing back into the atria when the ventricles contract. These valves ensure that blood only moves in one direction through the heart, maintaining the proper circulation of blood throughout the body.


Through how many heart valves must a blood cell pass as it moves from the brain to the lungs?

A blood cell must pass through two heart valves to travel from the brain to the lungs. As it exits the brain through the superior vena cava, it passes through the tricuspid valve, then through the pulmonary valve to reach the lungs for oxygenation.


How does blood enter a red blood cell?

Blood contains red blood cells. Red blood cells don't contain blood. Blood does not enter the red blood cell.


During the heart attack cardiac muscle cell are deprived of their blood supply yet the atria are still receiving blood. Why?

Well, the blood vessels that supply the heart with blood so that it can function can become blocked. Thereby causing heart damage. However, even during a heart attack, the heart may continue to beat, so blood will continue to enter the artia.

Blood in, blood out.


How many heart valves would a blood cell travelling from the renal vein the the pulmonary vein pass through?

Two, the blood will flow into the right atrium through the tricuspid valve (#1) into the right ventricle. The right ventricle will contract and send the blood through the pulmonary semilunar valve (#2) to the lung. The blood will return through the pulmonary vein but will not pass through any more heart valves until it passes the left atrium.

What are the names of the three blood vessels that carry blood around the body?

There are three blood vessels. 1. Arteries - these blood vessells carry blood away from heart to the cells of the body. They have a pulse and they are walled with elastic fibres. 2. Veins - Carry blood from the other parts of the body to the heart. They have valves to stop backward flow of blood. 3. Cappilaries are only one cell thick in reality, and they help to diffuse substances from the blood to the cell through the cell membrane (which is selectively permeable). They diffuse useful substances to the cell, and diffuse waste substances out. Hope that helps ;)
