How does the heart get oxygen from the blood?
The heart gets the oxygen from the red blood cells that "trade" CO2 for oxygen in the lungs and travels back up to the heart and gives the heart a bit of the oxygen and then gives the rest of the oxygen to the other organs (like the alveoli and the liver and the gut ect)
Is the pulmonary trunk oxygen rich or oxygen poor?
Oxygen poor. It carries oxygen poor blood from the right ventricle of the heart to the lungs to be oxygenated.
What pumps oxygen-rich blood to the body?
I think you meant "through the body". if that is so: the heart does, it pumps oxygen poor blood to your lungs. then the blood absorbs the oxygen with the help of diffusion. this is like smoke: smoke doesn't stay together, it goes to places where no smoke is. the same counts for your blood, there is no oxygen in it so the oxygen goes into your veins. then the heart pumps it around the body until the oxygen is used up. the process will start over again.Your heart.
What side of the heart pumps oxygen rich blood?
The left ventricle pumps oxygen rich blood out of the heart through the aortic valve. The heart works as a pump with an average of 72 beats per minute in healthy adults.
Where does oxygen poor blood first enter the heart?
somewhere
How long can the heart muscle be deprived of adequate oxygen supply?
30 minutes
What must the heart do when muscle cells are oxygen deprived?
continue aerobic metabolism when skeletal muscle cannotcontinue aerobic metabolism when the skeletal muscle cannot
When muscle cells are oxygen deprived the heart still pumps, what must the heart cells be able to do?
It must be able to continue aerobic metabolism when skeletal muscle cannot
What happens when the heart is deprived of oxygen?
we will die
Why is oxygen so much more critical to the heart muscle then to skeletal muscle?
It isn't more critical, the heart muscle itself is simply one of the most important and necessary muscles which we need to survive. Any muscle when deprived of oxygen will begin to die off, in the case of a thigh muscle however it's more likely to just necessitate amputation (to prevent gangrene from rotting tissue) or it would just result in the muscle not working anymore. The only real distinction that if the heart muscle just "doesn't work anymore" you're dead, you can survive without a bicep or tricep, not without a heart.Oxygen is vital to all muscles. Without oxygen cells die. When oxygen is not received to a skeletal muscle, the muscle wil begin to die out and you will feel tightness, cramps and a lot of pain in the effected region. When heart muscle is deprived of oxygen that is what is known as a heart atack. Blood (oxygen) is blocked from the heart and the muscle of the heart (myocardium) begins to die off. If too much of the myocardium dies the heart will not work properly. The heart will begin to go into Ventricalarfibrulation (V-Fib).
What brings oxygen deprived blood to the heart?
veins
Do you bleed from the mouth during a heart attack?
Not from the heart attack itself. In a heart attack, the heart is deprived of oxygen from the blockage of a coronary artery. This does not usually cause bleeding, but it does cause the death of the muscle cells if they don't get oxygen.
If a person has angina pectoris and is probably having an MI explain what may be happening to the heart?
Angina Pectoris is when the heart is deprived of oxygen-rich blood. Because the person is not getting blood to the heart, this causes heart muscle to die which in turn causes the heart attack.
Where does right side of heart pump blood to?
The right side of the heart pumps deoxygenated blood (blood deprived of oxygen) to the lungs where it can then receive oxygen.
What is variant angina?
is chest pain or discomfort that occurs when the heart muscle is not getting enough oxygen-rich blood for a short period of time
Ischemia occurs when the heart muscle?
regenerates
What part of your body is affected by Angina?
Angina is a pain or discomfort in the chest that is often felt has a squeezing or pressure-like feeling. This discomfort can also be felt in the shoulders, arms, neck, jaws, or back. Anginal pain usually lasts for no more than 2-10 minutes. It is relieved by rest or nitroglycerin. It is commonly found in the chest area. Angina is usually a sign of coronary artery disease(CAD). It occurs when the blood vessels leading to the heart are blocked. The blockage decreases the blood and oxygen flow to the heart muscle. When the heart muscle is deprived of oxygen you will feel chest pain and other symptoms.
