The Cardiovascular System The heart is one the primary organs in our body. The cardiovascular (CV) system is made up of the heart‚ the blood and the vessels through which blood travels. The CV system works in sequence with the respiratory system to maintain homeostasis. The heart acts as a pump which move the blood through the blood vessels to the tissues and organs of the body. This allows the CV system to help maintain homeostasis by enabling it to carry out its four major functions

BTEC Level 3 Unit 2: The Physiology of Fitness Describe the musculoskeletal and energy systems response to acute exercise. What is an acute response? An acute response is an immediate response to exercise. Acute exercise will last throughout the full length of your training session. During the training session our bodies begin to respond to the exercises we are doing and begin to feel the changes within our bodies and mind due to physical strain and stress of the physical activity in lots

CARDIOVASCULAR SYSTEM OF THE HEAD NECK The cardiovascular system consists of the heart‚ blood vessels‚ and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygen‚ nutrients‚ hormones‚ and cellular waste products throughout the body‚ the cardiovascular system is powered by the body’s hardest-working organ — the heart‚ which is only about the size of a closed fist. Even at rest‚ the average heart easily pumps over 5 liters of blood throughout

Cardiovascular Disease Ashley Cookie Cardiac Arrest Mr. Stapleton November 20th‚ 2012 Would you like to feel or be close to death? How would you like to have your heart pump rapidly out of control? A cardiac Arrest is the absence of ventricular contraction that results in systemic circulatory failure. A Cardiac Arrest is something that can happen out of nowhere without you knowing. You can be cooking and you just collapse and go into Cardiac Arrest. It’s that easy!
