Think of it as like a shower head. The more you turn up the dial (blood pressure), the stronger the water shoots out of the head (coronary perfusion rate).

What is transmural perfusion pressure?
Transmural perfusion pressure represents the amount of pressure in the coronary arteries that supply the layers of the heart muscle (the TRANSMURAL part). The formula is: Aortic diastolic pressure - LVEDP (L Ventricle End Diastolic Pressure). Keep in mind the coronaries ONLY receive blood during diastole because of the twisting forces applied on the heart during systole.
What type of circulation provides blood to the heart's tissues?
The coronary circulation provides blood to the heart's tissues. The coronary circulation includes the coronary arteries and coronary veins.
What is the purpose of a thallium heart scan?
The purpose of a thallium heart scan, also known as a thallium stress test or myocardial perfusion scan, is to evaluate the blood flow to the heart muscle. It is used to diagnose coronary artery disease and assess the severity of blockages or narrowing in the coronary arteries. The scan helps determine if there is enough blood supply to the heart during exercise or stress.
What does perfusion refer to in physiology?
In reference to physiology perfusion is the process of blood being delivered to a capillary bed in the biological tissue. Normal levels of perfusion can be tested by looking at skin color or skin temperature.
What vessels carry blood to the cardiac muscle?
It would be the Coronary arterie
Coronary perfusion pressure?
the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.

What are some common diet-related diseases in Singapore?

What is the movement of blood around heart tissue called?
The movement of blood to the heart tissue is called myocardial perfusion. In order for the myocardium (the heart muscle) to get oxygen and nutrients it has its own circulation providing a blood supply known as the coronary circulation. The coronary arteries (oxygenated blood vessels of the heart) supply nutrients and oxygen to the heart muscles between heart beats when the heart is relaxed (during diastole). Blood is routed from the surface of the heart muscle to deeper tissues of the myocardium. After delivering oxygen and nutrients to the cells of the heart, coronary veins pick up the blood and route it into the pulmonary (lungs) circulation where it can become re-oxygenated and return oxygenated blood back to the heart.
Which of the choices below does not involve tissue perfusion?
Tissue perfusion is the amount of blood that the tissues receive during circulation. When a person has decreased tissue perfusion, the tissues are receiving inadequate blood supply.
What are the signs of Coronary Heart Disease?
There are different signs of coronary heart disease such as heart pains or feelings of low blood pressure. Thoughts of this should be consulted with a doctor.
Which blood vessels supply blood to the heart muscle?
The heart muscle is supplied with oxygenated blood by the coronary arteries. Along with the oxygenated blood, the arteries also supplies the heart muscle with nutrient-filled blood.
How is an abnormally functioning colon related to increase blood pressure?

What is perfusion phase in medical terms?
The perfusion phase is the part of a contrast scan in which the contrast is moving into the blood vessels.
The circulation of blood within an organ or tissue in adequate amounts to meet the cells' current needs is?
Perfusion
