What else can I help you with?
Does blood flow from the coronary sinus into the coronary arteries?
no it flows to your heart
What is the flow of blood to the tissue of the heart?
coronary circulation
What are the three major circuits of the blood?
Systemic circuit- blood flow in the body Coronary circuit- blood flow in the heart Pulmonary circuit - blood flow in the lungs
What is the difference between pulmonary system and coronary system?
Coronary or cardio is blood flow. Pulmonary or respiratory is breathing.
When do coronary arteries primarily receive blood flow?
during diastole
What is it meant when people say somebody has had a coronary?
They used to mean a coronary thrombosis - a blockage in the blood flow to the heart. This was/is also known as a heart attack.But, with advances in medical science they may be referring to a coronary bypass.... surgery to alter the flow of blood so as to avoid damaged blood vessels.
Where are the coronary blood vessels?
Blood enters the coronary arteries just above the aortic semilunar valve. After systole (a ventricular contraction), the valve closes. The closing valve causes blood to back flow against the valve. At this time, the backward flow of blood enters into the coronary arteries.
Coronary blood flow is greatest during what phase of the cardiac cycle?
diastolic
What drug dilates the coronary blood vessels thus increasing the flow of oxygenated blood to the myocardium?
Nitroglycerinmorphine
Coronary perfusion pressure?
the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.
What phase of cardiac cycle do coronary arteries receive blood flow?
The Coronary Arteries receive blood during Diastole. While the heart is contracting, they are squeezed shut and little blood flows through them.
Why does blood not flow through the coronary arteries when the heart is contracting?
because it didn't feel like it
