Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Organism Physiology Paper Deborah Chase Biology 101 Professor Y. Henry March 9‚ 2015 Organism Physiology Paper (Chimpanzees) Chimpanzees are hominid species of apes native to Africa and the closest related to humans which they share 95-98% of human DNA. Earlier research reports that the oldest known primates are about 65 million years old with the chimpanzees emerging about 20 million years ago. It is thought that the chimpanzee’s level of intelligence has allowed it to survive

Pericardial effusion is a cardiovascular disease‚ and it arises when too much fluid accumulates around the heart and the pericardium. Signs and symptoms may not surface‚ even if one has severe pericardial effusion‚ notably when the fluid has accumulated slowly. However‚ if signs are present‚ they may include: cough‚ pain when breathing while lying down (orthopnea)‚ fatigue‚ low-grade fever‚ shortness of breath‚ difficulty breathing (dyspnea)‚ chest pain (on the left side of the chest or behind the

I. ANATOMY AND PHYSIOLOGY OF THE HEART I. LOCATION OF THE HEART The heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is surrounded by the pericardium. Its size is about that of a fist‚ and its weight is about 250-300 g. Its center is located about 1.5 cm to the left of the midsagittal plane. Located above the heart are the great vessels: the superior and inferior vena cava‚ the pulmonary artery and vein‚ as well as the aorta. The aortic arch lies

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

Risk Factors for Cardiovascular Disease Large scale studies have been undertaken to find the risk factors for many common diseases‚ including CVD. Epidemiologists (scientists who study patterns in the occurrence of disease) look for correlations between a disease and specific risk factors. Two commonly used designs for this type of study are; • Cohort studies- a group of people are followed over time to see who develops a disease • Case control studies- a group of people who have the disease
