Biology Task 2 Our organs all play a role in maintaining a constant internal environment, The liver maintains a constant level of glucose and amino acids, the lungs supply oxygen to cells. The physiological reason for Mo Farah’s increased breathing is that the body is attempting to return to its normal equilibrium level of 37 degrees Celsius and maintain internal stability which is called homeostasis.This ensures that the internal body temperature remains at a set point. This is called negative feedback; the hypothalamus sends impulses through the sweat glands to secrete. This reduces the heat by evaporation of sweat. Blood is sent to the surface of the skin to dispel heat.
Homeostasis is the maintenance of constant conditions in the internal environment of the body despite large swings in the external environment. Hormones have an important role in this system. Hormones are made of proteins; they are released by glands, in to the blood stream, where they reach target cells. A specific hormone will fit a specific receptor protein, and this brings about a change in that cell. Negative feedback mechanism A negative feedback in the body is where a change the level of one natural leads directly to a drop or increase.
Inform your instructor of any possible health problems that might be affected if you participate in this exercise. PROCEDURE Each person in a lab group will take turns being the subject and the tester. When it is your turn to be the subject, your partner will be responsible for recording the data on your lab sheet. Set up the Heart Rate Monitor. Open up Logger Pro,go to File, then Open.
Your assessor will ask you to complete workbooks, to cover each unit of this award, which will differ, depending on which awarding body is being used. Therefore, the guidance answers enclosed are based on the ‘outcomes’ for each unit, which will support your knowledge, and evidence for your award. Unit 4222-232 Move and position individuals in accordance with their plan of care (HSC 2028) Outcome 1 Understand anatomy and physiology in relation to moving and positioning individuals 1. Outline the anatomy and physiology of the human body in relation to the importance of correct moving and positioning of individuals 2. Describe the impact of specific conditions on the correct movement and positioning of an individual.
Unit 5.5 HomeostasisP5/M2- explain the concept of homeostasis/discuss the probable homeostatic responses to changes in the internal environment during exercise. Homeostasis is a state of balance inside the body, where the systems work together to keep it all functioning normally. The endocrine system keeps this internal balancing act going by releasing chemicals called hormones, these chemicals are controlled by negative feedback. Homeostasis also means that everything stays the same, so this therefore means that even when things do change around the body pretty much every minute of the day, homeostasis will make sure our body system is working to the correct level. It’s also important to keep your system working in the correct way and
Patients will have to go through an evaluation based on; overall strength, range of motion, flexibility, balance, posture, body mechanics, coordination, endurance, and general mobility. (aurorahealthcare.org) After they go through the evaluation process they will have a treatment program designed for them to target the areas they are weak in and hopefully strengthen them. Physical therapists will use an array of equipment and environments to assist them in implementing the most beneficial treatment program for the patient. They will use basic gym equipment such as; medicine balls, treadmills, stair climbers, dumbbells, ramps, exercise bikes, stability balls and electro stimulation machines, plus many more, too many to list. Occupational therapy is a service that helps patients strengthen the way their nervous system functions.
Administer any medication correctly and in accordance with care plans etc. and company policy. Outcome 2 Be able to assist in minimising individuals’ pain or discomfort The learner can: 1. describe how pain and discomfort may affect an individual’s wellbeing and communication- Pain and discomfort can present limitations of functional ability and interfere with quality of life. Providing appropriate pain management assures the dignity and well being of a patient, as well as affording a better quality of life. Unit 4222-232 Move and position individuals in accordance with their plan of care (HSC 2028) Assessment Criteria Outcome 1 Understand anatomy and physiology in relation to moving and positioning individuals The learner can: 1. outline the anatomy and physiology of the human body in relation to the importance of correct moving and positioning of individuals- Facet Joints link the vertebrae and allow us to bend and twist.
You have been asked to prepare an information booklet on homeostasis(Task 5) and include your research data (Task 6). Guidance:- to achive (P5) your booklet should include an introduction that explains in general what homeostasis is and includes an explanation of a negative feedback mechanism. The next section should include a series of flow charts showing how homeostatic mechanisms stop heart rate, breathing rate, body temperature and blood glucose levels rising or falling to dangerous levels. (P5) Guidance:- to achieve (M2) your booklet should include a section on the probable homeostatic responses to changes in the internal environment during exercise. This could be achieved be discussing the following • When you start to run, your muscles need a lot more oxygen and glucose.
Outline the body’s response to stress (6 marks) There are two types of stress: acute and chronic stress. Acute stress (short-term stress) causes the body to respond through a process called the sympthomedullary pathways. This immediate response is achieved because of the hypothalamus’s direct link to the nervous system which causes the activation of the sympathetic nervous system (SNS). This is a branch from the autonomic nervous system. The SNS also regulates the sympathetic adrenal medullary system (SAM).
