Feedback Mechanisms a. Compare and contrast the two feedback mechanisms our bodies use to maintain homeostasis. The body needs to maintain a stable internal body temperature for homeostasis. If we are too hot, our sweat glands are activated and blood flow to the skin is increased (Bartholomew & Martini, 2012). The perspiration evaporated on the skin causes a cooling effect the restores homeostasis (Bartholomew & Martini, 2012).
For example, during this course, you might take a look at how the heart performs its particular function. The relationship between the healthcare provider and his or her patients would be lot stronger cause the healthcare provider know her Anatomy and Physiology, she will able to help them understand better what going on with their body and what is the cause of it. When taking a basic anatomy course your goal should be learn and understand the structures and function of the
Answer Selected Answer: positive feedback Correct Answer: positive feedback • Question 6 2 out of 2 points Neurohormones are produced by Answer Selected Answer: nerve cells (neurons) Correct Answer: nerve cells (neurons) • Question 7 2 out of 2 points Which is a physiological response that take place in many animals when their body temperature goes up? Answer Selected Answer: increased blood flow to the skin to release heat by radiation Correct Answer: increased blood flow to the skin to release heat by radiation • Question 8 2 out of 2 points Which of these is the most effective way to prevent dehydration due to sweating? Answer Selected Answer: drink plain water Correct Answer: drink plain water • Question 9 2 out of 2 points
How our body maintains a constant temperature Temperature receptors in the skin detect changes in the external temperature of the body. They pass this information to the processing centre in the brain, called the hypothalamus. The processing centre also has temperature receptors to detect changes in the temperature of the blood. The processing centre automatically triggers changes to the effectors to ensure our body temperature remains constant, at 37°C. The effectors are sweat glands and muscles.
White (2012) • What are the strengths and weaknesses of biological and humanistic theories? With which do you agree more? Strengths – both acknowledge that they are not the only approach to personality. Other results help with your personality for example, the environment you were brought up in. White (2012) Weaknesses – “With the humanistic theory, you are in control of your personality on a conscious level and with the biological theory; your genetics controls your personality.
A biological perspective is relevant to the study of Psychology in three ways: 1. Comparative method: different species of animal can be studied and compared. This can help in the search to understand human behavior. 2. Physiology: how the nervous system and hormones work, how the brain functions, how changes in structure and/or function can affect behavior.
Homeostasis is for the procedure of the body to uphold a relatively consistent internal state. The nervous system sends and also receives these signals about temperature, blood pressure, hydration and more factors. The endocrine system tends to carry chemical messengers to adjust all the bodily functions. During different forms of exercise, the body’s internal environment is then changed and placed under a considerable amount of stress. Throughout homeostatic feedback mechanisms, the body is allowed to maintain a very healthy internal environment and then rapidly return to normal after all of the exercise ends.
* 1. Please define the terms anatomy and physiology. * Anatomy is the study of the body’s structure and physiology is the study of the body’s function. Explain the connection between anatomy and physiology within the human body; basically how do they influence one another? * Anatomy and physiology influence each other by allowing people to grasp changes and symptoms that occur with certain diseases.
Hypnosis is a psychological and physical or mindbody inclusive therapeutic treatment which facilitates relaxation which is integral in helping to prevent illness and change behaviour. Hypnosis has great potential to un block or change negative emotions by working directly with our internal communication system where messages are transmitted cell to cell. PNI studies have shown that neuropeptide receptors are present on both the cell walls of the immune system and brain and that they work together as a single system of defence against illness. Scientists have stated that our thinking has a direct effect on our physical health and that we can to some extent literally think our selves well or unwell. Hypnosis uses the power of suggestion during the trance state induced by the hypnotic induction to make subjects feel positive and healthy
According to the Le Chatelier’s principle, if a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change and a new equilibrium is established. In this experiment, the effect of temperature change on the equilibrium position of the above chemical equation by comparing the state of the reacting mixture when it is in high temperature and low temperature. As the ∆H>0, the increase of temperature would expected to shift the equilibrium to the right. Procedure: 1. Using a measuring cylinder, pour 20 cm3 of 0.01M saturated cobalt (II) chloride solution at 0℃ and pour about 100 cm3 of deionized water to a 250 cm3 beaker.
