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.

1.1 We should always check equipment which we are going to use if it is safe and working properly, we should wear PPE every time we are undertaking any task, ensure that we are trained to do the task, we should keep the working place safe and clean. When we are about to take measurement from an person we need to make sure that the person know exactly what we are going to do and asking permission for the task we are about to do. Recording the task in the chart and keep it confidential to protect personal information during the course of our work.

27. Heat the water to 40°C with an alcohol lamp by setting up the apparatus as shown in figure 3 below:

1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate.

The human sense of touch is known as the somatic or somatosensory system. The skin is the biggest and most complex organ in the somatosensory system.The somatosensory system permits the human body to experience pressure, texture, temperature, and pain, and to see the position and development of the body's muscles and joints.The receptor cells in the skin can be separated into three useful classifications: mechanoreceptors that sense pressure and surface, thermoreceptors that sense temperature, and nociceptors that sense pain. Thermoreceptors distinguish changes in temperature utilizing two sorts of receptor cells: warm and cold. Thus, thermoreceptors on the skin detects the temperature signal using two specific receptors cell: warm and cold.

After the 5-minute period, take the Elodea and thermometer out of the beaker, pour the mixture into the beaker down the drain and rinse.

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.

Fill a test tube about 1/3 full with cold tap water for use in step 34.

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

b. Place crushed ice in the beaker so the water level is just below the top of the

The difference between anatomy and physiology is anatomy is the study of the bodily structure of other humans and animals. Physiology is the study of normal bodily functions in humans and animals. For example, anatomy is looking at the muscles and organs and Physiology is looking at the organs function and the muscles functions. The term that would most describe the pig dissection is anatomy because in the pig dissection we were looking at the different structures of the organs and muscles inside the pig while if the term was physiology we would be looking at the organs working. Homeostasis is the tendency of an organism to regulate its internal conditions, usually by a system of feedback controls, to stabilize health and functioning, regardless

Get room temperature water and make sure it is 50ml and pour it into the 2 measuring cups.

However, ask a neurologist how many senses the human body has, and you might get a surprising answer. Many identify nine or more senses- some listing as many as twenty-one. The first category is made up of the somantic senses, which we usually lump under “touch”- including our perception of pressure, heat, and pain. The third category, however, is not nearly as well-known. These are the interoceptive senses-those that deal with data originating in the body itself.
