What is homeostasis? Homeostasis is the tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to stabilize health and functioning, regardless of the outside changing conditions. In humans, homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit. For example, we sweat to cool off during the hot summer days, and we shiver to produce heat during the cold winter season.
Word origin: from the Greek: homeo, meaning unchanging + stasis, meaning standing.

    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.)…

    Unit 5 Health And Physiology M2 Homeostasis

    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.

    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.…

    P5 Unit 5 homeostasis

    Homeostasis is the mechanism in our body that regulates and maintains a stable and constant environment. This enables our body to respond to changes in the environment around us as. The homeostatic mechanisms in our body, observe and monitor conditions and will then make a judgment whether to change the way the body functions is order to adapt to the outside surroundings better. The main organs involved in homeostasis are; the brain, liver, skin and kidney’s. The skin is involved as its acts as a protective layer and also regulates body temperature. The liver breaks down harmful substances and the kidneys regulate water levels and waste products. In the brain the hypothalamus controls everything and changing them to fit into the outside surroundings. Negative feedback is also linked in as it is the process of homeostasis. It is negative because it is in a negative situation and will not kick it unless there’s something wrong.…

    Homeostasis is the control of internal conditions, be it temperature, specific blood conditions or other variables within living organisms, the purpose of homeostasis is to provide a consistent internal environment for set processes to occur. The endocrine system is made up of glands that produce hormones and release them into the blood, they cause certain reactions to occur in specific tissues. The endocrine system affects a large number of the body’s functions, including, metabolism, sexual function, reproduction, moods, and development. (dummies.com) The urinary system is the main excretory system and consists of 2 kidneys, 2 ureters, the bladder and the urethra.
