P5
Homeostasis is a natural response in which the body systems work together in order to keep the internal environment of the body at a constant rate despite changes in the external surroundings. Homeostasis involves the maintenance of many different controllable things within the human body. This includes; oxygen levels, blood pressure, carbon dioxide levels, pH, water levels, hormones, body temperature and glucose levels. All of these things remain at a constant regulated rate even when there are changes in the external environment to the body. All of the body's cells and tissues are used for homeostasis. The changes which occur in the outside environment are detected by receptors and when certain changes are detected the body initiates the appropriate response. A homeostatic response can either be a behavioural change or physiological changes.
For example; when our body temperature decreases we put on extra clothes in order to become warmer and increases out temperature. This would be an example of a behavioural response to changes in the outside environment.
A physiological response to changes in the environment would be when our blood glucose levels decrease due to the release of insulin and glucagon is then released in order to maintain these levels. The release of glucagon in the body results in the release of glucose by the body’s cells.
The body responds to changes in the external environment in many different ways. Some examples of homeostatic responses would be a change in

    Homeostasis is your body’s ability to maintain an internal environment that is constant, no matter what is happening outside of it. The body has a lot of responsibility, like blood pressure, temperature, and things like glucose levels even. Blood pressure can be regulated through homeostasis (Thibodeau, 2008). Homeostasis hinders organs from exerting so much, thereby preventing disturbance to metabolism and other physiological conditions of the body. So, when the body’s blood pressure is high, or even low,…

    10.1 Homeostasis. 1. Homeostasis is the maintenance of a constant internal environment. 2. • • • For any homeostatic control to occur there must be: a stimulus which is a change in the internal environment, a receptor which can detect the stimulus, an automatic or self-regulatory corrective mechanism, which bring about a negative feedback. Homeostasis may include the regulation of the following: Blood glucose level, Blood water potential, Temperature.…

    1a – Explain the structures of a human cellMost human cells contain small structures known as organelles (“little organs”), each of which performs a highly specialised task, such as manufacturing protein. Organelles are usually surrounded by a membrane, and they float in a jelly-like substance called cytoplasm. Ninety percent of cytoplasm is water; it also contains enzymes, amino acids, and other molecules needed for cell functions. The structure…

    With all of the activities going on in the organism, there must be guidelines and limits that the body must follow in order to preserve health. The body must maintain a STABLE INTERNAL ENVIRONMENT, even when external environment is changing. The term used to describe the body‟s ability to maintain these stable conditions is HOMEOSTASIS. ( Ex. thermostat and heater and temp regulation in the hypothalamus.)…

    Homeostasis is the need for an organism or a cell to regulate its internal environment (conditions within the fluid surrounding its body cells) by a system of feedback controls to stabilise health and functioning despite the outside changing conditions. This is important as this is what maintains and helps internal conditions (body temperature) to remain stable and constant.…

    Homeostasis is simply how the body keeps conditions inside the same. It is described as the maintenance of a constant internal environment. Generally, the body is in homeostasis when its needs are met and it’s functioning properly. Every organ in the body contributes to homeostasis. A complex set of chemical, thermal, and neural factors interact in complex ways, both helping the body while it works to maintain homeostasis. In homeostasis there is the concept of Negative feedback which ensures that, in any control system, changes are reversed and returned back to the set level. There are four different homeostatic mechanisms for regulation these four are the heart rate, breathing rate, body temperature and blood glucose levels. Negative feedback system is made out of receptors to detect change, a control centre to receive the information and process the response and effectors to reverse the change and re-establish the original state. (Anatomy & Physiology, 2013)…

    Homeostasis is a term used to describe an internal environment being in a state of constant conditions, such as constant temperature, pH, and etc. It is important because staying at an equilibrium requires the least amount of energy and provides the perfect environment for desired reactions to occur. If at any given time, the equilibrium is disturbed and the homeostasis shifts, then internal environment becomes stressed and favored reactions do not take place. Blood pH is an example of homeostasis where the right concentration of carbon dioxide and oxygen exists using buffers exists to keep a favorable environment where it is not too acidic and not too basic. Another example is body temperature where the body has to maintain 37 degrees Celsius in order for majority of the enzymes in the body can function properly.…

    The first concept is homeostasis. Many people identify homeostasis with body temperature and blood pressure. Homeostasis in the body can be looked at as a regulator that keeps the body well balanced. A great example of this would be, as mentioned before, body temperature. If the body is hot, homeostasis allows the body to sweat so that it may cool off. If the body is cold, homeostasis makes the body shiver to warm up. In looking at homeostasis we see that the human body is a wonderfully working machine.…
