From blood vessesl just like anything else. It gets blood that has already been oxygenated from the lungs just like any other muscles.
It is the heart that pumps fresh oxygen in the blood.
blood coming from the HEART is rich in oxygen
Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
I believe all organs (including the heart) require oxygen.
The coronary arteries transport oxygen-rich blood to the heart muscle. These arteries are responsible for supplying the heart with the oxygen and nutrients it needs to function properly. If there is a blockage or narrowing in these arteries, it can lead to various heart conditions such as heart attack.
The heart uses about 20% of the body's total oxygen supply. It requires a constant supply of oxygen to function properly and sustain the body's energy needs. If the heart does not receive enough oxygen, it can lead to serious health issues such as heart attacks.
The heart beats accelerates because your organs need more oxygen and the heart pumps the oxygen into the blood and when you need more oxygen than normal your heart rate is faster than normal.
The heart utilizes around 60-70% of the oxygen it receives at rest. This high demand for oxygen is necessary for the heart to continue functioning properly and efficiently.
the heart does not give the body it's oxygen it is the lungs. The heart is used to pump the blood to the lungs to pick up oxygen and then to pump the blood throughout the body and add oxygen to the blood cells.
The organs most sensitive to deprivation of oxygen are the heart and the brain.
The chambers of the heart need oxygen,and oxygen is part of the respiratory system which if the respiratory is gone,the heart will not receive oxygen and wouldn't pump blood this is my opinion by:jitiy
The heart muscles.
