Analyse how the cardiovascular and the digestive system interrelate to perform energy metabolism. Energy is used up all the time for body processes. Energy starts at conception and continues to carry on until you die. The amount of energy you need depends upon your age‚ sex and your level of activity. Food provides the energy we use; our foods bring us the vital energy that our body is burning throughout the day. Body growth‚ development and functioning are some of the vital and fundamental aspects

PPHN is a life threating condition; due to the failure of the normal circulatory transition that occurs after birth. Epidemiologic studies have some that PPHN is more common in Asian and Black maternal race and men. PPHN occurs when a newborn’s circulation system does not adapt to breathing outside of the uterus‚ oxygen is decreased due to the pressure in the arteries forcing the blood away from the lungs.

Essay on Congestive Heart Failure According to a recent study‚ people over 40 have a 1 in 5 chance of developing Congestive Heart Failure in their lifetime. Nearly 5 million people in the United States—mostly older adults—already have Congestive Heart Failure‚ and the number of people with Congestive Heart Failure keeps rising. About 550‚000 people develop Congestive Heart Failure each year. This is because people are living longer and surviving heart attacks and other medical conditions that

The cardiac cycle cannot be described as a linear series of events associated with the flow of blood through the four chambers. One can not accurately describe the cardiac cycle by simply tracing the path of blood from the right atrium‚ into the right ventricle‚ into the pulmonary circulation‚ the venous pulmonary return

The cardiovascular system is an organ system that distributes blood to all parts of the body. The cardiovascular system is a very important system in your body because it is the body delivery system for circulation of blood‚ which is made up of blood‚ blood vessels‚ and the heart. Cardiovascular can be compared to the muscular pump equipped with one-way valves‚ also a system of large and small plumbing tube where the blood travels through. The circulatory system is important because it transport
