What else can I help you with?
What keeps food from going down your lungs?
epiglottis
What is the valve that prevents blood returning to the right ventricle after it pumps?
The aortic semilunar valve prevents backflow of blood from the aorta to the left ventricle.The aortic valve prevents backflow of blood from the aorta to the left ventricle of the heart.aortic valve
What is the last valve oxygen depleted blood must pass through before pumping to the lungs?
The last valve oxygen-depleted blood must pass through before being pumped to the lungs is the pulmonary valve. This valve separates the right ventricle from the pulmonary artery and prevents blood from flowing back into the heart. Once the blood passes through this valve, it enters the pulmonary artery and travels to the lungs for oxygenation.
What valve keep food from going to the lungs?
Gullet
Where does blood flow from when it passes through the semilunar valve and into the lungs?
Semilunar valves are found throughout the body in veins, as they prevent backflow of deoxygenated blood. In the heart, there are two semilunar valves, the pulmonary semilunar valve and the aortic semilunar valve. The pulmonary semilunar valve is the gateway to the pulmonary artery, which then goes to the lungs. The aortic semilunar valve is the gateway to the aorta, which distributes oxygenated blood to the rest of the body.
What is the name of the organ that keeps food from going into the lungs?
The epiglottis
What is pulmonary valve?
The pulmonary valve is a semilunar valve that prevents the back flow of blood back from the lungs to the right ventricle.
What ventricle pumps blood from the heart to the lungs?
Right ventricle pumps blood through the pulmonary valve to the pulmonary artery to the lungs
What is the valve between the right ventricle and the pulmonary artery?
The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.
What kind of blood going back to the lungs?
deoxygenated blood
When does the blood flow to the the lungs and from the lungs?
# Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs. Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs. Carbon dioxide leaves the body when you exhale. Once the blood is purified and oxygenated, it travels back to the left atrium through the pulmonary veins.
When blood moves from the lungs to the heart it is now?
Blood is de-oxygenated when it it pumped into the lungs, and after going through the lungs, is now oxygenated.
