Zi Lin January 25‚ 2014 2B Cardiovascular Diseases The heart is an essential organ in the cardiovascular system responsible for pumping oxygen and nutrition filled blood to all parts of the human body. It is composed of four chambers; two upper chambers called the right and left atrium‚ and two lower chambers called the right and left ventricle. A structure called the septum is what divides the heart into right and left halves. Four heart valves keep the flow of blood in one direction. At rest‚ the

Describe the size‚ shape‚ location‚ and orientation of the heart in the thorax. 2. Name the coverings of the heart. 3. Describe the structure and function of each of the three layers of the heart wall. 4. Describe the structure and functions of the four heart chambers. Name each chamber and provide

The routes of the systemic circulation is as the blood leaves both ventricles‚ it enters the aorta and goes into the body. It travels through many parts of the body before it reaches the heart. The coronary circulatory routes is in the heart. It starts off at the superior venacava. After it reaches the venacava‚ in then travels into other parts of the heart before it is finally absorbed and the whole process starts over again. The difference between the coronary circulatory routes and the systemic

The cardiovascular and respiratory systems work towards a common goal of getting oxygen to tissues and getting carbon dioxide out of the body (Cloe‚ 2013). Each system has their own function to help the other‚ but the main focus is to oxygenate the blood. The body does this through one of the bodies organs‚ the lungs. Low oxygenated blood is pumped through the pulmonary arteries to the lungs. Whenever we breathe this low oxygen blood is turned back into oxygenated blood when carbon dioxide is forced

discuss the Roper Logan and Tierney model of nursing which will be used as a framework for this assignment. In order to have an understanding on how venous ulcers occurs a description of the normal and abnormal anatomy and physiology of the venous system will be addressed. It will then show how the effect of pain due to the chronic ulceration has affected Martha’s ability to carry out two of the 12 activities of living (Roper et. al 1990). It will discuss the biological issue such as pain‚ odour

The cardiovascular system consists of the heart‚ blood vessels‚ and blood. This system has three main functions: Transport of nutrients‚ oxygen‚ and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide‚ nitrogenous wastes). Atria: Ventricles: In a four-chambered heart‚ such as that in humans‚ there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs‚ and the left ventricle pumps

important nutrients and keeps you alive could come to a shocking and deadly stand still. All because of a faulty diet. I sat down today with a few people to test their knowledge and find out their opinions when it comes to their dietary health and cardiovascular health in general. I thought it would be best to pick out a range of people to interview and see how each subject responds to the same set of questions. Our first interviewee is from Polk High School‚ 15 year-old‚ Hannah Williams. 1) How many
