Corronary circulation, via the left and right coronary arteries. These are the first branches off the ascending aorta and sub divide into the left anterior descending and the right posterior descending. These further divide into the marginal and thecircumflex branches. These feed all the major areas of the heart.
The circuit that the blood follows from the heart to the body's tissues and back is called systemic circulation. It involves the flow of oxygen-rich blood from the heart to the body's tissues through arteries and the return of oxygen-poor blood back to the heart via veins.
Systemic Circulation
Circulation of the blood
To have a high rate of respiration requires a high blood flow to distribute the oxygen to the tissues, this increases the heart rate it also increasing the blood flow to the tissues.
Deoxygenated blood is in the systemic veins. The pulmonary veins carry oxygenated blood to the heart to be pumped to body tissues.
The flow of blood from the heart to the lungs and back to the heart is called pulmonary circulation.
The flow of blood from the heart to the lungs and back to the heart is called the pulmonary circulation.The blood flowing from the heart to the lungs would be deoxygenated and blood flowing towards the heart from the lungs would be oxygenated.
Arterial circulation.
Blood flows away from the heart and is measured as blood pressure. This is a measure of the passage or flow and the resistance of the flow in the arteries.
The answer is quite simple. To have a high rate of respiration requires a high blood flow to distribute the oxygen to the tissues. Increasing heart rate is one means of increasing the blood flow to the tissues. The other means in increasing the amount of blood that is from the left ventricle with each contraction.
Tissues with the best blood supply include the heart, lungs, liver, and kidneys. These organs require abundant blood flow to support their high metabolic demands and functions.
