Question to answer after watching the Interactive Physiology - The Immune System: Innate Host Defenses 1. Name the two major categories of innate (nonspecific) defenses: • Surface Barriers • Innate Internal Defenses 2. Surface barriers include the Intact skin and mucous membranes of the respiratory‚ gastrointestinal and genitourinary tracts. 3. List the three properties of skin that help it resist invasion: • Keratin: tough protein in skin cells‚ forms an abrasion- and water-resistant outermost

PET 3351 Exercise Physiology Second Exam Review (Fall 2012) Chapter IV: The Physiological Basis of Muscular Strength and Flexibility 1. Strength is operationally defined as the maximal force that can be exerted in a single effort. Using this definition‚ strength should be assessed using one repetition maximum (1 RM)‚ though we often estimate strength using tests that may involve multiple repetitions. 2. In strength training and rehabilitation‚ emphasis should be given to both the concentric

Abstract Acid Rain has a lot of effects on living organisms and on the environment. This experiment has two purposes. One is to determine the acidity of rainwater in certain areas in the Philippines. Another purpose is to determine which type of area-urban or rural- is more subjected to acid rain. The experiment was done by first collecting rainwater from selected rural and urban areas. After the collection was done‚ the rainwater samples were tested using a pH meter. The results of the pH test

always more visible in aquatic environments such as streams‚ lakes‚ and marshes. Many lakes and rivers are already acidic without the effects of acid rain. Their pH levels go up to 6 and 8. Once a stream or lake has been affected by acid rain‚ the organisms living in the aquatic environment begin to die out. The solution to decreasing the amount of damages acid rain has on the environment is to lower the sulfur

ANATOMY AND PHYSIOLOGY OF THE HEART Anatomy: The heart and heart wall layers: The heart is located in the left side of the mediastinum; it consists of three muscle layers the Endocardium‚ myocardium‚ and epicardium. The epicardium is the outermost layer of the heart. The myocardium is the idle layer of and actual contracting muscle of the heart. The endocardium is the innermost layer and lines the inner chambers and heart valves. Pericardial sac: The pericardial sac encases and protects

Aviation Physiology Aviation physiology is an important study for pilots‚ flight attendants‚ and other crewmembers. Its study is often brushed over during initial training. The current FAA Knowledge Examination system emphasizes multiple choice knowledge at the expense of a deeper understanding. The course will give you a chance to explore aviation physiology in a more focused manner. Physiology is the biological study of a living organism‚ in whole or in part. Aviation physiology is narrowed

The process of osmosis and its importance to living organisms Osmosis is the process by which there is a net movement of water through a semi permeable membrane from an area of high water potential to an area of low water potential. Within a cell‚ osmosis has the following effect. If the water potential of the cell is lower than that around the cell water will move across a concentration gradient into the cell. If this is the case‚ the increase in water in the cell‚ may cause the cell to swell
