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

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

Premium Vein Blood Cardiovascular system
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

Changes that Occur in the Cardiovascular System As we age‚ certain changes in the heart are inevitable. Even in the absence of disease‚ the wall of the heart thickens‚ heart rate slows‚ maximum heart rate declines‚ and the heart doesn’t pump as efficiently as it once did. Health problems‚ such as hypertension‚ coronary disease‚ congestive heart failure‚ and myocardial infraction are more common in the elderly and aggravate age- related degenerative change in the circulatory system and that’s why I’m here

Structure of the heart: The heart is at the centre of the cardiovascular system. It is a hollow muscular pump that drives blood through the arteries‚ which allows it to reach the working muscles and tissues. The heart is split into two halves. The right side of the heart is separated from the left by a solid wall known as the septum. This prevents any blood on the right side coming into contact with the blood on the left side. The right side of the heart sends deoxygenated blood to the lungs in

1.6 Blood Pressure Blood pressure is the main factor in sustaining blood flow through tissues. The force applied to the arterial walls as the heart pumps blood throughout the circulatory system defines the physiological meaning of blood pressure (Bojanov‚ 2009). Blood pressure is determined by the force‚ heartbeat rate‚ and resistance to blood flow through vessels. Cyclic changes in arterial blood pressure are partially attributed to the rhythmic contractions in the left ventricle (Iaizzo‚ 2009)
