 * Sweating/Skin/ Excretory system**

When you sweat it cools down your body to prevent overheating. Sweating lowers your body temperature because the sweat is cooling the body down. The skin stops losing heat to the air and absorbs it. The more skin shown the more heat is absorb into the body. Sweat glands help col our body down. People with large sweat glands tend to sweat more than someone with small sweat glands. The more you sweat the more water you need to drink. Tp prevent dehydration drink lots of water to give back to your body what it has sweated out.

The skin is sometimes referred to as the integumentary system because it consists of four tissue types. The skin also has several accessory organs such as hair, nails, sweat glands and sebaceous glands.

When a person is working or playing where it is hot, it puts stress on the body's cooling system. When the heat is combined with other stresses such as hard physical work, loss of fluids, or some medical conditions, it may cause "heat- related illness, disability and even death." This can happen to anybody! Even if you are young and fit. The harder your body is working, the more heat it has to lose. We can prevent or control the amount of stress by builting up an immunity to the heat. The longer you do hard work in the heat the better your body becomes at keeping cool. We can also prevent heat stress by drinking fluids constantly through out the day and replenishing salt by eating salty foods. Heat stress is dangerous and hazardous because it can cause heat rash, sunburn, heat cramps, fainting, heat exhaustion, and heat stroke. All of these can either cause cloges sweat glands, blistering and peeling of the skin (sunburn), drainage of salt (heat cramps), and you may encounter not enoigh blood flow to your head which can cause loss of consciousness.
