What else can I help you with?
What keeps blood moving in a circuit through the body even when the pressure is relatively low?
your heart is a pump and keeps the blood flowing
What do arteries contain that prevent the back flow of blood?
Nothing, it is only pressure that keeps blood moving in the right direction in arteries. Veins have valves that prevent backflow of blood, but arteries do not.
What keeps the blood moving round and round?
The pumping of the heart keeps the blood moving
Arteries contain valves that do what?
No arteries do not contain valves since there is enough pressure from the heart to force blood through these vessels without significant backflow between contractions.
How does the pulsating blood pressure in the largest arteries relate to their structure?
It reveals their elasticity. When the heart contracts and forces blood into the large arteries near the heart, they stretch to accommodate the greater blood volume (systolic pressure). Then, as the blood continues on in the circuit, their walls recoil, keeping pressure on the blood which keeps it moving (diastolic pressure).
What force keeps the ball moving in a circle?
The force that keeps a ball moving in a circle is called centripetal force. This force acts towards the center of the circle and prevents the ball from moving in a straight line.
What force keeps an object moving in a circle. in what direction does this force act?
The Centripetal force keeps a object moving in a circle and its force and acceleration are directed toward the center of the circle
Brief meaning of the law of inertia?
A moving object keeps moving, unless you force it to stop. It keeps moving in a straight line, unless you force it to change direction. It keeps moving at a constant speed, unless you force it to speed up or slow down. A stationary object remains stationary, unless you force it to start moving.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
Is the force that keeps objects moving in a circle centripetal force?
true
What is the force called that keeps an object moving?
The force that keeps an object moving is called inertia. Inertia is an object's resistance to changes in its motion and is related to its mass.
The force that keeps objects moving in a circle is called centripetal force.?
true
