A--when someone hike, how will the altitude affect your body?
its affect on these systems are concern ofthis question:
nervous system, kidneys and urinary system, endocrinesystem .

When someone hike and goes to a higher altitude than usual, it affects the heart rate and it becomes more difficult to breath. In higher altitude there is less oxygen and so this affects breathing. People get more tired because the source of oxygen is less in higher altittudes.

Sympatetic nervous system increases its activity, that is why heart and blood presure rate increases. There is also a pulmonary vasconstriction and during excercise it may lead to pulmonary hipertension.

Altitude can increase urinary output. The bodys kidneys respond to lower oxygen by producing more red blood cells to increasing oxygen. To make room for the new cells the body eliminates through urine.

Explanation:

When hiking in high altitudes, while people try to breathe heavily to get more oxygen they fail because there is a lack of it. Threre is less oxygen throughout the respiratory system and this afects the muscles and limits excersise preformance.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
