Hi Everyone! Welcome To My Channel Ali Academy Biology Lectures • About This Video ........................ • In This Video Lecture You Will Learn Basic Concept Of Homeostasis • homeostasis, any self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival. If homeostasis is successful, life continues; if unsuccessful, disaster or death ensues. The stability attained is actually a dynamic equilibrium, in which continuous change occurs yet relatively uniform conditions prevail. • The control of body temperature in humans is a good example of homeostasis in a biological system. In humans, normal body temperature fluctuates around the value of 37 °C (98.6 °F), but various factors can affect this value, including exposure, hormones, metabolic rate, and disease, leading to excessively high or low temperatures. The body’s temperature regulation is controlled by a region in the brain called the hypothalamus. Feedback about body temperature is carried through the bloodstream to the brain and results in compensatory adjustments in the breathing rate, the level of blood sugar, and the metabolic rate. Heat loss in humans is aided by reduction of activity, by perspiration, and by heat-exchange mechanisms that permit larger amounts of blood to circulate near the skin surface. Heat loss is reduced by insulation, decreased circulation to the skin, and cultural modification such as the use of clothing, shelter, and external heat sources. The range between high and low body temperature levels constitutes the homeostatic plateau—the “normal” range that sustains life. As either of the two extremes is approached, corrective action (through negative feedback) returns the system to the normal range. • About This Channel..................... • I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources. • One-stop destination for all biology lectures. • _ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial • _ The videos are categories under various heading to make the students life simplified • Visit My Other Channel Playlist ..................... • NMDCAT PART 1: • New 1st Year Biology • NMDCAT PART 2: • New 2nd Year Biology • Class 11th Lectures: • New 1st Year Biology • Class 12th Lectures: • New 2nd Year Biology • Class 10th Lectures: • • Matric Biology • Subscribe My Channel: • / aliacademya7r • Social Link........................ • Instagram: • https://instagram.com/ranaalibiologis...
