Respiratory physiology

Respiratory distress syndrome (RDS) commonly known as hyaline membrane syndrome occurs in many premature births. As the gestational age for a baby decreases subsequently the likelihood of them having this condition will increase because their lungs are severely underdeveloped. The problems that stem from RDS include lack of surfactant, smaller alveolar surface span, elevated compliance of the small airways, and occasionally the ductus arteriosis might be a factor if it doesn’t close shortly…

For example, endurance training can cause adoptions in the respiratory muscles. This increases the maximum ventilation capacity and lessens the likelihood of respiratory muscle fatigue during exercise when compared to untrained individuals. Additionally, this causes the respiratory muscles become stronger which increases the volume of air inspired and expired for breath. This changes the amount of carbon dioxide and oxygen…

In order to survive under several environmental influences, animals must possess biological mechanisms which enable them to regulate and maintain their internal environment. Temperature is one of abiotic factors that are inexorably linked to every animal’s physiological functions since it is considered a strong source of selective pressure on animals (Miller, 2010). Animals are categorized into thermoregulators and thermoconformers based on their mechanisms to maintain their internal environment…

The Animal Welfare Act is a federal law that makes the minimum standards and regulations for animal testing. This law’s purpose is to provide the minimum protection for animals used for animal testing, but 95% of the animals used are completely excluded, receiving no protection. Meaning this law only protects 5% of animals used in tests. The AWA regulations are so limited that psychological, and physical cruelty and suffering of these animals has continued. This federal law conflicts with…

Basic Anatomy and Physiology 02/15/2016 Unit 1 Chapter 1*3 1. Describe homeostasis and give three specific examples in the human body. Homeostasis is a systems that helps regulates the body systems and maintains keeping it stable. It also determines that it is used to name processes within living organisms. It?s constantly used to apply which is automatic control systems also known as thermostats. Occasionally recommends a sensor to capture changes in the condition to be regulated by the…

There are three common ethical concerns expressed regarding the quality of animal lives during animal testing. Animals should lead natural lives through the use of their natural adaptations and capabilities, should function well in terms of health and behavior , and should feel well and be free of pain and fear. Most scientists have “restricted conceptions of animal welfare that relate to only one concern”(Drummond) . We protect animals due to genetic conservation, environmental integrity ,…

A polygraph is a common instrument of measurement to calculate and document physiological aspects such as respiration rate, electrodermal activity, and heart rate. The relevant uses of measuring respiration rate as well as heart rate are quite common in a wide variety of applications. However, electrodermal activity and the galvanic skin response are not commonly measured things in places such as the medical field, or education. Electrodermal activity (EDA) refers to the variation of the…

subsequent to my research I discovered that even though physiology is the study of “natural science of the body” (Stegemann, J. (1981) Exercise physiology: physiologic bases of work and sport. Chicago 3: Year Book Medical Publishers), and does contain both practical and theory work, one has also discovered that work physiology has the important job of “humanizing man’s working place as a branch of ergonomics” ((Stegemann, J. (1981) Exercise physiology: physiologic bases of work and sport.…

alteration to cardiac function, CHF. It will discuss the three nursing assessments that are appropriate to use for each symptom to investigate further; these nursing assessments are pitting edema assessment, vital signs focusing on oxygen saturations, respiratory rate, and daily weigh. Lastly it will examine the interventions that are most suitable to prevent further damage, treat and support the best chances of recovery from CHF. In this case…

Media exposure can cause short term and long term effects. Short term effects are immediate and occur during the timeframe of exposure to the form of media. These short term effects can affect thought processes, beliefs, evaluative judgements, attitude, emotions, behavior, and physiological responses. (Potter 2014) Cognitive processes may be effected by supplying information and implementing new ideas. An example of a short term cognitive effect would be learning the outcome of a sports game or…
