The Changes of Heart Rate of Students during Human Dive Response when Resting and Submerged Abstract The dive response is known more popularly as a mammalian dive reflex. It is a survival mechanism built into mammal’s bodies‚ essentially. Over the years‚ scientists have been determined to find what triggers mammals to have a decreased heart rate when submerged under water allowing them to stay under the water longer when they do not typically live under water.

How Your Heart Works [pic] Your heart is a pump. It keeps blood moving around your body. The blood delivers oxygen and nutrients to all parts of your body‚ and carries away unwanted carbon dioxide and other waste products. The heart has four chambers - two on the left side and two on the right. The two upper chambers are called the atria‚ and the two lower chambers are called the ventricles. The two sides of the heart are divided by a muscular wall called the septum. Each side of the heart

Artificial Heart/ Heart Transplants A natural heart has two pumps‚ each has two chambers. The right atrium pumps oxygen-depleted blood from the body into the right ventricle. The right ventricle pumps blood to the lungs. The left atrium sends aerated blood from the lungs into the left ventricle‚ which pumps blood out of the body. With each heartbeat‚ the two atria contracts together‚ followed by the large ventricles. Congestive heart failure is when the heart fails to pump blood. Heart failure

Analysis: 1. Explain why blood pressure and heart rate differ when measured in a reclining position and in a standing position. When a person stands‚ the heart must pump blood against the pull of gravity to reach important areas such as your brain. Veins must work hard to get blood back to your heart. As a person reclines‚ the heart does not have to pump as hard to reach the same areas‚ decreasing the blood pressure. Also‚ a person is usually more relaxed in a reclining position‚ which
