HOMEOSTASIS
Homeostasis can be defined as a point of balance or internal equilibrium that all kind of system both living and non-living can work to keep themselves in this state of balance.
Mechanisms of homeostasis in human body
Temperature Regulation: If your body too hot or cold, there are several ways in which your temperature can be controlled. They involve sweating, shivering, capillaries and hairs. As we learn in the class when your body becomes;
Too hot
When we get too hot: (1) The sweat gland in the skin release more sweat. This evaporates, removing heat energy from the skin. (2) The blood vessels leading to the skin capillaries becomes wider , they expand allowing more blood to flow

These glands release the hormones into the blood stream and are transported to the various cells and body parts. When the hormones reach the target site, they bind to the receptor cells with a lock and key mechanism. The hormone may be present within the nucleus or on the surface of the cells. Once bound to the receptor, the hormones transmit a signal that triggers an action by the site. Hormones control the organ's function and affect the growth and development of the organs. It is due to the hormones that the sexual characteristics of the organs develop and act accordingly. They also determine the use and storage of energy in the body regulate the fluid, salt and sugar levels in the blood. Minute amount of hormones trigger large reactions within the body. All hormones are proteins, but all proteins are not hormones. Steroids are not derived from proteins, but from the fatty substances from fatty …show more content…
The two best described are defecation and childbirth. It is defined as a mechanism whose output stimulates an increase in output i.e. birth. Also, "A system's response to external stimuli leading to further changes that serve to reinforce the initial response, thereby creating and accelerating a cause and effect loop." This mechanism is potentially dangerous because it will cause the body to respond as strong as it can until there is a release of stimulation birth or uterine rupture. A negative feedback mechanism is one where the output causes a decrease in subsequent output a balancing loop. There are lots of negative feedback loops in the body as this is the way that most systems maintain homeostasis the ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. A negative loop could be hormone secretion. Hormone levels decrease so the body stimulates the organ to produce more. At a certain level, the body recognizes that there is too much and pulls back production the negative

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 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.…

    As mammals our aerobic metabolic system requires oxygen for us to sustain life. The organ that transports oxygen from the environment into the body where it is needed, are the lungs. Oxygen is transported through cellular respiration from the lungs to tissues and organs. Between 2,100 to 2,400 gallons of air is breathed to fuel 2,400 gallons of blood that is pumped into the heart. Respiration is controlled by the medulla oblongata, which deals with the autonomic function of breathing. This characteristic allows one to breathe without having to think about the process but can also be overridden and controlled in certain situations. As a result of respiration, carbon dioxide is produced where it is removed for oxygen to be restored. The purpose…

    Two mechanisms the body uses to cool itself are when blood vessels in skin dialate to radiate heat and sweat glands increase sweat production. 10b. Two mechanisms the body uses to heat itself are when blood vessels in the skin constrict, and reducing heat loss and muscles begin to shiver, generating heat. 11a. The stimulus in the feedback loop is when the body senses the temperature being too hot and the response to it is using one of the two mechanisms to cool it down.…

    Homeostasis is a point of balance or internal equilibrium. All kinds of systems — both living and non-living — can work to keep themselves in this state of balance, but the word "homeostasis" is most often used in biology, particularly to describe how the human body reacts to changes and keeps itself within certain parameters to ensure that it can function correctly. These reactions include a range of responses, from the release of hormones to regulate internal imbalances to sweating to lower body temperature.…

    Homeostasis is the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function. This is essential for the human life. Every piece of this experiment was to prove the slightest change can through your body off balance.…

    Negative feedback is a principle which is used by the body in order to return systems to its normal level; it does this by turning the corrective measures off. Homeostasis uses the principle of negative feedback in order to maintain a constant internal environment. There are a number of different examples of negative feedback such as thermoregulation, regulation of blood glucose and the regulation of water potential. The control of the heartbeat can also use negative feedback mechanisms.…
