Evaluation Of A Good Physiological Experiment

This section of the paper will explain in detail about the method and procedures that will be done in the future experiment. Recruitment strategy and criteria will be presented for participants.

In order to maintain a healthy body temperature, the heat produced with in the body or absorbed from the environment must be balanced from the heat lost from the body. A normal body temperature is measured at 37 degrees.

2. Physiological state in defined as “the condition or state of the body or bodily functions”. This can be measured when we perform our observations. By measuring a patient’s respiratory rate, oxygen saturations, peak flow (in asthma patients), pulse rate, systolic and diastolic blood pressure, core temperature, blood sugar, pupil reaction and Glasgow coma scale. All these combined measurement can give us an insight into the patient’s health or Physiological state.

This paper explores and explains the findings of the heart rate experiment conducted by the students of Grand Canyon University for the Anatomy and Physiology 202 Laboratory course. Over a two week time span, students were asked to record their heart rate, before, during, and after activities as instructed by the professor. Specifically, this paper focuses on the female students, comparing the heart rates of individuals who reported that they drink coffee versus those females who reported that they do not drink coffee. The effects of caffeine contained in the coffee were examined and it was noted that those who drink coffee have lower heart rates before, during, and after times of examination. These findings suggested that the hypothesis proposed prior to research, Females Who Drink Coffee Have a Higher Heart Rate Prior to Exams, was an incorrect statement.

The muscular system also helps to keep us warm and keep us at the correct temperature. Thermoregulation is a process that allows your body to maintain its correct temperature of 37 degrees c. Muscles contribute to your bodies temperature because they receive messages from the brain when you are cold. Our bodies response to being cold is shivering which warms you up on the other hand if you are

On Tuesday the 20th of September, a presentation was required of all students to show a video of individual experiments after a week was given on the day of the original assigning. Given the task of performing an experiment in order to become acquainted with the Scientific method, students of Biology 621A were required to record their experimentations in full - providing a question to be answered, constructing a hypothesis, designing an experiment that would aid in the proving (or disproving) of the hypothesis and collecting the data found from the experiment. These would go on to be graded based on their overall presentation quality, and content in regards to the mastery of the scientific method while proving its functionality and existence in scientific experiments no matter how small, while determining factors like independent or dependant variables.

The conceptual overview, along with the experimental procedures are found in the NPB 101L Physiology Lab Manual 2nd Edition. More specifically, pages 55 to 63 provided a full insight to all the experiments in the respiratory lab. In addition, a list of required materials was given for every experiment. The authors of this lab manual were Erwin Bautista and Julia Korber. As for data acquisition, the BIOPAC software was used to collect and record data for all the trials. Furthermore, the teaching assistants had calibrated each station prior to initiating the lab exercises. For the entirety of the respiratory lab, a human subject was used in all the experiments. A 22-year-old female was the participant for the first two experiments regarding

Comparing my results to the average results provided on table #2 on page 2.8 of the biophysical evolution lab manual, my best value for the sit and reach is 31.5cm which is considered average for a male aged 15 to 19 years old. It is in the middle of the average range, therefore my forward flexion is good but not the best for my age group. My average best hip flexion value is 86ﾰ (94ﾰ on left leg and 78ﾰ on right) and compared

Alcoa defines heat stress as the total heat load on the body arising externally from exposure to heat in the workplace, and internally from metabolic heat production associated with physical activity. Alcoa safety department works all summer and any time that heat will be major hazard to the employees. There are three disorders and diseases

: Homeostasis of the body or the existence of a stable internal environment inside of an organism is essential to life. Organisms maintain certain levels internally to sustain life, and often-outside factors can cause these levels to change in a manner not intended. Thus the body responds to the new stresses of the environment with auto- regulation, and extrinsic regulation through the use of positive and negative feedback loops in the body. In particular exercise evokes different reactions as the body undergoes stresses. In the experiment performed, the test subject was required to undergo changes in order to maintain optimal homeostatic conditions. In this experiment, skin color, perspiration level, body temperature, breathing rate, and heart rate were all monitored during the

The normal body temperature of the average person is 96.2° - 99.4° F. The hypothalamus regulates the body temperature. The production of body heat is by metabolic chemical reaction and skeletal muscle tone and contraction. Chemical thermogenesis is the heat-producing mechanism in the body. A fever causes the hypothalamus to reset its internal thermostat. This change causes the hypothalamus to set a “higher level in response to endogenous or exogenous pyrogens” (Huether 331). When an individual has a fever the thermoregulatory mechanisms adjust heat production, conservation, and loss to maintain core body temperature to compensate for the increase in temperature. This higher temperature acts as a new set point for the hypothalamus.

Traditionally, specially in the OR settings, there is a lot of routines and protocols with the goal of providing consistency of practice across different

The two experiments I will be doing are in the doctor’s office, and at an interview. When I go to the doctor’s office I will sit in the doctor’s chair instead of the chair I am suppose to sit at. My prediction will be that the medical assistant will ask me to move to the other seat. When I go to my job interview I will make sure to sit forward as I am getting interviewed and touch the interviewee on the shoulder when I first meet him or her. My prediction will be that they will be able to tell that I am very interested in the job and by me touching them on the shoulder, that they will get a sense of trust in me. I believe these two experiments will be a great because I go to the doctors very often so it will be very interesting to see how they

If your body's homeostasis gets out of balance, you might have a problem producing heat from the nutrients you take in or the outside environment might cause problems. If you're exposed to extreme cold, your body temperature could fall, leading to hypothermia. This slows organ function, producing confusion and fatigue and even death. In extreme heat, your body might be unable to cool down, at which cellular proteins denature, causing the active site in proteins to change, thus causing metabolism stop which could result in heatstroke.

In this article I have learned many different helpful things. The article states many different heat illnesses, and how to handle them. Some of these damages can be lethal, and lead to death or some cases permanent damage. The article states information given by NATA which is the National Athletic Trainer 's Association. The purpose is to provide enough information for best practices for heat illness. So in the article, it states information about the following: heat syncope, external heat injury, external heat stroke, heat exhaustion, and exercise associated muscle cramp. So to start off heat syncope occurs when a person is standing in heat for
