The document discusses homeostasis and how the human body maintains internal equilibrium in the wet tropics climate. It notes that the wet tropics have high humidity and temperatures between 80-90 degrees F during the wet season from November to March. At night, temperatures fall to the low 60s. The body uses several mechanisms to maintain its core temperature, like sweating and shivering. If a person is exposed to extreme heat for too long without water, it can lead to heat cramps, exhaustion, or stroke with core body temperatures over 103 degrees F. Key organ systems like the integumentary, nervous, and circulatory systems help the body regulate temperature in the wet tropical environment.

2. Homeostasis: The ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. Normal Environmental Conditions in the Wet Tropics: During the night, the temperature gets to around low 60’s. This can cause an affect on the homeostasis on humans because of the need to maintain their normal temperature. ( Their body will start doing everything it can to conserve its heat).

3. Weather Conditions in the Wet Tropics: There is a wet summer season from November to March. During the wet season, humidity is usually over 90 degrees and the normal everyday temperature is between the 80’s and 90’s. There is also a dry winter season from April to October. The temperature is in the 70’s and at night it gets down to the low 60’s. Also, the tropical sun is much different than it is in the north, It can inflict a burn after only 15 minutes. Use a hat, sunglasses, and sunscreen.

4. Typical Ranges of Homeostasis In Humans: To maintain normal body temperature. The body will almost always start to sweat at the temperature of 37 degrees Celsius. If the skin temperature drops below 37 degrees, the body will start trying to conserve its heat. The body will stop sweating, start to shiver to increase the heat production in the muscles, and hair stands up to trap in the heat of your body.

5. Examples of Human Adaptations Which Maintain Homeostasis and Their Affects on Human Physiology: A humans temperature an water level is an adaptation to the wet tropics heat. The water in your body turns into sweat and is absorbed by the sun taking some of the heat of your body with it. You may also lose some of the salt amount in your body so you can slightly increase your intake on salty foods if it does not cause or aggravate any health problems.

6. Maximum Limits Human Can Stand in the Wet Tropics: Wet in the tropical sun long enough, people can have heat cramps, Heat exhaustion, and heat stroke. The maximum for heat stroke is For the person to have a body temperature of 103 degrees and whom Have had almost no water to drink. Three Organ Systems Affected By the Wet Tropical Weather: Integumentary System: the sweat glands to keep you cool. Nervous System: (peripheral system) the sensory organs such as eyes, nose, and fingers. Circulatory System: helps maintain normal body temperature.
