The body system that most interests me is the cardiovascular system‚ I chose this system because I’m fascinated with how the heart works and how the blood flows throughout our whole body. The heart is a muscle that contracts which allows blood to be pushed throughout the body. The heart provides many nutrients and blood to the whole body along with many vital organs. The heart is spilt into four chambers: the right atrium‚ left atrium‚ left ventricle‚ and right ventricle. The blood flow starts in

Mechanisms of Blood Flow in the Human Forearm during Mental Stress‚ Following Isometric Exercise and after Occlusion ------------------------------------------------- 1. Introduction A common technique in measuring blood flow in the human forearm is by venous occlusion plethysmography. The fundamental principle is that if the venous return from the arm is blocked‚ the forearm will swell at a rate relative to the rate of the arterial inflow (Whitney‚ 1953). However‚ the rate of increase in volume

The cardiovascular system is a vital part of our body and it is crucial for us to lead a healthy lifestyle to maintain the structures of our body. Structures of the cardiovascular system include the heart‚ blood vessels and blood. Structures of the Cardiovascular System Heart The heart is the most important organ in our body as it provides every part with blood. The heart pumps blood by producing electrical impulses which cause the ventricles to contract and relax and pump blood to the

Age Related Changes that Occur in the Cardiovascular System Age Related Changes that Occur in the Cardiovascular System In the normal conduction of the heart the electrical impulse starts in the SA node‚ also called the pacemaker of the heart. The electrical impulse travels through the right atrium and through the Bachmann’s bundle into the left atrium. This stimulates the atria to contract. Next the signal travel to the AV node. The AV node slightly delays the signal. This delay is needed

Blood Type Lab Report Sherman Chen 3B Introduction: The purpose‚ nature‚ and expected findings of the activity. In this lab activity‚ we were first asked to find the blood types and then count the number of blood cells. In the first part of the lab‚ we had to find the ABO and Rh blood type of four simulated blood samples. We did this by observing the antigen/antibody reaction in each of the four samples of simulated blood; if there was agglutination it meant that was the blood type. In the

Systolic (contraction) and diastolic (relaxation) pressures refer to the ventricular contraction and relaxation. With knowing the two pressures‚ one can distinguish if he/she is at a normal

Cardiovascular Disease Information HCA 240 February 22‚ 2013 Gioia Scoppoa Cardiovascular Disease Information Cardiovascular disease refers to conditions that narrow or block blood vessels. These conditions can lead to a heart attack or stroke. According to Richard P. Lewis M.D. (Can Cardiovascular Disease be prevented)‚ “Cardiovascular disease is the common chronic illness in our society.” Coronary artery disease is a disease that supplies the muscle with blood. The blood flow can become

Case Study # 2: Age-Related Changes that Occur in the Cardiovascular System Sarah Miller ITT Technical Institute As the heart ages it goes through changes such as thickening of the walls‚ slowing heart rate‚ decrease in maximum heart rate‚ loss of efficiency in pumping. The layers of the heart include the pericardium‚ epicardium‚ myocardium‚ and endocardium. The pericardium is the membrane that protects; it is a sac that the heart sits in and has a layer of fluid between for shock and absorption
