What occurs when the blood flow is cut off to a portion of your heart muscle?
A heart attack
Which blood vessels supplies the heart muscle with oxygenated blood?
Blood is oxygenated in the lungs travels through the pulmonary veins into the heart. The heart muscle itself receives oxygenated blood through through the coronary arteries that branch off from the aorta.
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 happens when part of the heart dies from lack of blood?
A heart attack occurs when the blood flow is cut off to a portion of your heart muscle.
Cardiac muscle tissue?
Involuntary muscle only found in the heart regulates the beat at which the heart pumps blood to the arteries which then blood follows to the capillaries and is oxygenated ten follows the veins back to heart and the cycle begins again but before i get off track the main function of cardiac muscle tissue is to regulate the beat of your heart to (in the average human) about 70 beats per minute.(is not striated like skeletal muscle tissue)
Why does the myocardium receives it blood from coronary arteries and not from the cardiac chambers?
Myocardium is a type of muscle tissue. The reason why the myocardium receives its blood from coronary arteries and not from the cardiac chambers is because the blood from the cardiac chambers does not contain oxygen and nutrients.
How does the heart pump blood to itself?
Interestingly, none of the blood pumped THROUGH the heart provides circulation TO the heart itself. The heart muscle has its own set of arteries and veins (such as the descending and circumflex) from which to obtain oxygen and nutrients.
What type of workout should you do if your goal is muscle toning?
You have to jerk it off or use a shake weight.
What blood vessels carry blood to heart muscle?
Capillaries deliver blood tot he muscle of the heart. In fact, it is about 1 capillary per contractile cell of the heart. These cells require a rich blood supply since they are very active cells.
Should I worry about clogged arteries?
Yes, as these can cause clots that can break off and block blood flow to the heart muscle (heart attack), lungs (pulmonary emboli) or the brain (stroke).
Where is location of the coronary arteries of the heart?
The coronary arteries are located on the surface of the heart, branching off from the aorta. They supply the heart muscle with oxygenated blood to support its function.
What type of chocolate ward off heart disease?
Dark chocolate, the higher the % the better.
