Regulating Body Temperature: Homeostasis


regulating Body Temperature: Homeostasis

control is the process of keeping the body at a constant temperature is abortion protected by the Constitution of 37C. The processing centre automatically triggers changes to the effectors to ensure our body temperature remains constant, at 37C. Without a regulatingmechanism, the organism will die. When the glucose level becomes too high, the pancreas produces an insulin hormone. Stimulus (cold/hot) causes change in variables (body temperature). Through behaviour, they actively seek cooler or warmer areas to lower or raise their body temperature to acceptable range. For example, diabetes is a condition in which the body can not regulate the level of glucose in the blood. A chicken is a bird; like mammals, birds are endotherms andgenerate their own body heat. If the body is too hot, glands in the skin secrete sweat onto the surface to increase heat loss by evaporation. The concentration of salt and glucose (sugar) in the body is maintained at a constant level (in the absence of negative factors the amount of blood in the body is about 5 liters.

The warm thermogram (l) shows the body at normal temperature 37C (red) - the extremities are cooler (peach and pink areas). They are ectotherms, which means they don't havephysiological mechanisms to maintain their body temperature. The rate of respiration is also increased. Show greater agression and the advancing dog will submit. The regulation of homeostasis is manifested by perspiration, a protective reaction of the body to overheating. The human body reacts to this disorder with the help of the urinary system. The heat of evaporation is taken up from the air, as well as from the body. They only sweat when its too hot. In hot climate the blood vessels dilate and produce lot of sweat. One is sweating by the sudoriferous glands in the skin to cool the body. The main aim of the homeostatic is to maintain good environment forinternal organs, so to keep the heart rate in good level thereceptors sends messages to the brain and the brain then sendsresponds to the cardiac centres by nerve impulses. If we are too hot or too cold, the processing centre sends nerve impulses to the skin, which has two ways to either increase or decrease heat loss from the body's surface.
