Detailed explanation-1: -The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
Detailed explanation-2: -Blood pressure is the force of the blood pushing against the artery walls. The force is generated with each heartbeat as blood is pumped from the heart into the blood vessels. The size and elasticity of the artery walls also affect blood pressure.
Detailed explanation-3: -systole-this is when your heart contracts, pushing blood out of the chambers.
Detailed explanation-4: -As the center of the circulatory system, the heart is an essential organ for maintaining the overall functioning of the body. The cardiovascular system consists of many veins and blood vessels which ensure that all parts of the body are provided with an adequate amount of oxygen and nutrients to function efficiently.
