The body has a special mechanism called homeostasis that’s responsible for maintaining internal stable conditions inside the body. When conditions change, the body tries to regulate its internal environment by using feedback systems. When dealing with hypertension the body uses a negative feedback system that regulates your blood pressure. A negative feedback system reverses a change in a situation that’s controlled. As shown in the book, a stimulus disrupts homeostasis by increasing the blood
Why is it important for organisms to regulate internal temperatures or metabolic processes at different temperatures? -Certain vital enzymes will become inactive if the temperature is too cold, and denatured if the temperature is too hot. The organism cannot function without these vital enzymes. 8. Explain how the process of blanching is used in the food industry and why a specific temperature is required.
Because we have homeostasis we also have a lot of other processes and these can both be positive and negative and to help make sure our bodily system is functioning properly. An example of this is that our cardiovascular system must always be working in the correct order to make sure that all your blood is being pumped properly around your body making sure that it is carrying all the oxygen and vitamins that we need for the production of energy that is in our organs. But if we do not get enough oxygen in our body we can all suffer because we wont have enough energy to make sure you get through your day to day activities. This could then lead on to other organ problems because you are making your body overwork when it does not have enough energy to be able to do this. This shows that you always have to make sure that you do as your body asks you, each when it’s needed and drink when its needed because your body needs energy to keep you going.
____blows out hot air_________ 2. What does a thermostat do if it gets too hot? _______stops blowing hot air_____________ 3. How do our bodies sometimes act like a thermostat? _______in homeostasis, negative feedback is used in the same way, by increasing the stimulus until it is excessive and then decreasing or stopping___________________________________________________ _______________________________________________ Gizmo Warm-up To survive, an organism must be able to maintain stable internal conditions in a changing environment.
Homeostasis is the ability to maintain a constant internal environment in response to environmental changes. This is managed in the human body by a series of highly evolved and complex interactions that work to maintain or alter internal system to return to a normal and stable range that will best serve the individual’s needs; this range can be different depending on the physical and psychological functionality of the individual. This process is key to the survival of the individual as an inability to maintain homeostasis known as a homeostatic imbalance can lead to death usually through heart failure or can cause diseases such as diabetes and hypoglycaemia. There are 5 key parts of the body that help maintain homeostasis these are the liver, the kidneys, hypothalamus, the autonomic nervous system and the endocrine system. These work to maintain homeostasis in terms or heart rate, breathing rate, body temperature, blood glucose levels, iron levels and concentration of body fluids (blood water potential).
Homeostasis is the balance within the body to stay at a normal healthy level. Certain things can hinder your balance within your body like disease or disorder. The body will naturally try to bring your body back to its normal levels through this and also what is called a negative feedback system. You have receptors in your body called baroreceptors which are pressure sensitive nerve cells detect the high blood pressure. They then send nerve impulses to the brain which is the control center of your body.
P5: Explain the concept of homeostasis. M2: Discuss the probable homeostatic responses to changes in the internal environment during exercise D2: Evaluate the importance of homeostasis in maintaining the healthy functioning of the body Homeostasis is the process the body takes to keep the body in balance and ensures that there is a stable environment in which cells can function. Enzymes control the chemical processes in the body, these can be stopped, slowed down or sped up, when required if there are changes in the body, if the internal body systems aren’t maintain within a reasonable range the enzymes won’t be able to work. Different body systems work together to maintain efficient body functions. Homeostasis mechanisms control the body temperature, breathing rate, heart rate, blood glucose levels and many more.
Unit 4222-250 Support individuals to maintain personal hygiene Outcome 1 Understand the importance of good personal hygiene 1 Explain why personal hygiene is important. People should have a good personal hygiene to maintain their wellbeing and health. Showering or bathing on a regular basis, washing hair and good overall cleaning of the body can help to kill harmful bacteria which could lead to health problems and illness. By maintaining good personal hygiene is important to peoples social, health, psychological well being. Good personal hyginene helps to prevent or develop infections, illness or bad odours, it also helps with confidence, motivation, body image and self esteem.
The sweat glands produce sweat, which stays on the skin allowing the body to cool down as it evaporates. When the body is cold the hair erector pili contract raising the hair and trapping warm air next to the skin The skin excretes waste products in sweat which contains water, urea and albumin. Sebum is an oily substance that is excreted by the sebaceous glands, which helps to lubricate and protect the skin The skin synthesises vitamin D when ultraviolet light is present. Vitamin D is essential to allow the body to manufacture certain hormones The skin can convey changes in mood through colour changes such as blushing. The skin also gives clues as to the physical wellbeing
Unit 5 – Anatomy and Physiology P5 - explain the concept of Homeostasis Charlotte Miles Susanna Horwood – 201106386 What is Homeostasis? The word “Homeostasis” means ‘steady state. It is described as the body controlling inside conditions within the body, as steady as possible. Humans, along with the animals, need homeostasis, because the cells in individuals and animals are demanding but efficient at the same time. As human beings, our natural body temperature is around 37°C; however it is difficult to keep to that temperature because of the change to our environment, it is also important that our cells are functionally properly.
