Investigating the effects of carbohydrates on blood glucose levels INTRODUCTION There are two types of diabetes which includes diabetes inspidus however the disorder most commonly associated with the generic term ‘diabetes’ is diabetes mellitus. Diabetes mellitus is condition whereby blood sugar levels are far too high due to poor metabolism. There are two variations of the disorder which are Type 1 and Type 2 Diabetes Mellitus. Type 1 diabetes occurs as a result of the body’s inability to produce

consume is simply not good for our bodies-it builds up and eventually damages our health. Antioxidant vitamins-vitamins C and E‚ and beta carotene-may be what we need to "clean up" our systems. Excess sugar in the bloodstream can have very serious side effects. The extra sugar impedes blood flow‚ causing wounds to heal more slowly and infections to become more virulent. Just how this excess sugar causes damage remains a topic of debate. One plausible mechanism was suggested in Time by Dr. Michael

Describe how the body responds to stress (6 marks) Acute stress causes the arousal of the autonomic nervous system (ANS). The ANS comprises of the sympathetic nervous system (SNS) which prepares the individual for ‘fight or flight’ and the parasympathetic branch‚ which returns the individual to their original state of relaxation. Part of the SNS response is the sympathetic adrenal system (SAM)‚ this system along with the SNS is collectively called the sympathomedullary pathway. The SNS is activated

this paper is to define stress and how it effects the body ’s physiological systems. This paper will include the normal functions and organs involved in the following five physiological systems‚ cardiovascular‚ gastrointestinal‚ respiratory‚ immune and musculoskeletal. This paper will also include a description of a chronic illness associated with each physiological system and how the illness is affected by stress. Stress means different things to different people and stress effects people in different

Body fluids are maintained at a constant level by several homeostatic mechanisms: Osmosis- is the diffusion of water through a selectively permeable membrane known as a plasma membrane. Water is highly polar it is repelled by the lipid core (nonpolar) of the plasma membrane but can easily pass through the aquaporins created by the proteins in the membrane‚ so osmosis is happening all the time as water moves into and out of cells. Diffusion- Is where ions move away from an area where they are

Outline and evaluate the role of neural mechanisms in controlling eating behaviour (24 marks) Today there is enormous interest in the psychological factors that can affects a person’s eating habits‚ but some of the clearest research findings have come from research into the brain (neural) mechanisms controlling eating behaviour. One important mechanism to consider is the role of homeostasis in all mammals. Homeostasis is how the body maintains a constant internal environment. Our diet is essential

Maintaining a normal body temperature is crucial for optimal health and is one important aspect of homeostasis. Homeostasis is the body’s ability to balance varying internal conditions within narrow limits despite a constantly changing outside environment (Marieb & Hoehn‚ 2016). When a person is subjected to stimuli‚ which is a change in the variable‚ such as cold weather‚ temperature sensitive receptors in a person’s skin called thermoreceptors‚ detect this change. The receptors then respond providing
