Answer:
(for 1st question)
Plato's answer: This world exists because both systems are involved in the movement and support of the body, and they work together to perform these functions. Bones provide support and give the body structure. Muscles give strength, and the contraction and relaxation of muscles allow for different movements.
Explanation:
Another Answer: The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.
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.
