Deoxygenated blood enters the right atrium from superior and inferior vena cava after having been circulated through the body. ----------------------- From the right atrium‚ blood moves to the right ventricle and is pumped through the pulmonary artery to the lungs‚ where it receives oxygen. ----------------------- Oxygenated blood from the lungs then returns to the left atrium of the heart. ----------------------- Blood from the left atrium moves into the left ventricle. -----------------------

“SURGEON GENERAL’S WARNING: Smoking Causes Lung Cancer‚ Heart Disease‚ Emphysema‚ and May Complicate Pregnancy.” Almost everyone in America can read this message and pin point exactly where it came from. It is well known for being printed on every single pack of cigarettes sold in America and in other countries as well. It is mandatory for this message to be printed on every pack because of how serious the effects of smoking are and how easy it is to become addicted to smoking them. There are

OVERVIEW OF THE PROBLEM Coronary Artery Disease or Coronary Heart Disease (CAD/ CHD) is the primary cause which leads to the majority of all problems of the heart (AHA). More than 600‚000 Americans suffer from Coronary Heart Disease (CHD) ("Coronary heart disease" 2012). In order for an individual to be diagnosed with CAD there has to be a significant amount of plaque buildup which in time‚ if not treated could lead to atherosclerosis‚ the narrowing of arteries. (CDC‚ AHA). This disease has been

disorders are coronary heart disease and breast cancer. Coronary heart disease: Coronary heart disease is the build-up of plaque such as cholesterol and other fatty substances within the coronary arteries causing a reduced or no supply of oxygen to the heart. The process of plaque lining the coronary arteries is called arteriosclerosis. Coronary heart disease can be caused and triggered by many different factors. These include: Smoking; lifetime smoking roughly doubles your risk of developing heart

pressure exerted against artery walls created when the heart contracts to push oxygenated blood throughout the body. As blood pressure is represented by 2 numbers‚ systolic blood pressure is the upper number. A normal systolic blood pressure is 120 or below although it largely depends on the physical properties and capabilities of the individual. Q 2) what do you understand by the term diastolic blood pressure? Diastolic blood pressure indicates the pressure exerted against artery walls whilst the heart

How microscopes have contributed to our understanding of living organisms There are 2 types of microscopes these are; light microscope and electron microscope. Light microscopes use a beam of light however the resolution is lower than the electron microscope so the image is not clear‚ however they can view living organisms. These types of microscopes are used in schools to view simple cellular structures‚ which is good to teach simple biology Mitosis and meiosis can be seen with light microscopes

Hypertension Normal ABP : the pressure exerted by blood on the vessel wall of the arterial system from the beginning of the aorta to the start of the arterioles‚ it is about 120 mmHg systolic and 80 mmHg diastolic. Arterial blood pressure (ABP) = cardiac output (CO) X total peripheral resistance Hypertension : sustained elevation of the systemic ABP > 139 mmHg systolic & > 89 mmHg diastolic. Therefore : so long as CO is constant is relatively constant ; a change in the ABP is mainly due
