why does blood in the arteries flows in under pressure
Answers
The arteries are the large blood vessels that carry blood from the heart to all the organs and muscles of the body, to give them the energy and oxygen they need. The arteries manage the flow of blood by controlling the speed and direction it flows in.
Because the blood inside the arteries is being pushed round by the heart, the blood pushes against the insides of the artery walls. This pushing is your blood pressure. To cope with this pressure, the artery walls contain tiny muscles to hold them in shape and allow them to become wider or narrower.
Opening and closing different arteries affects your blood pressure. The more narrow your arteries are, the less space there is for your blood to flow in and the harder it pushes against the arteries’ walls.
The blood is pushed under ventricular contraction when the blood is in the ventricle...
hence the blood is pushed in the blood by pressure..
