Answer;
-Atrial contraction;
Explanation:
-The cardiac cycle comprises all of the physiological events associated with a single heartbeat, including electrical events, mechanical events (pressures and volumes), and heart sounds.The atria and ventricles alternately contract in each cardiac cycle. The pressures in the chambers change greatly over the course of the cardiac cycle.
-During atrial contraction, blood flows from atria (high pressure) to ventricles (low pressure). Similarly, this same pressure gradient exists during ventricular filling.
Answer:
C
Explanation:
Newton's Second Law of Motion states that acceleration is dependent on 2 things: the net force acting upon the object and the object's mass.
This law is shown is these equations:
acceleration=net force/mass
net force=acceleration*mass
