!?!DO DOGS SWEAT!?! (SWEAT GLANDS AND SWEAT) SCIENCE EXPERIMENT Crazy Chris is working up a sweat and shows you how important sweat really is to your body! Objective: To understand how sweat cools the body. Materials Needed: ~ Container ~ Water in a Bottle ~ Rubbing Alcohol ~ Desk Fan Step 1) Plug your desk fan in and turn it on Lo. Step 2) Place your hand over the container, and pour some of the water on your hand. Then place this hand in front of the desk fan. Step 3) Place you hand over the container again and pour rubbing alcohol on your hand. Then place this hand with your other hand in front of the desk fan. HOW IT WORKS: Sweat is made up of water, salt and a few minerals such as potassium which is produced in eccrine sweat glands. These glands are a tubular group of cells that are connect to the blood vessels, filter the blood and send water to the surface of the skin. Sweat cools your body by absorbing an enormous amount of body heat and as the water evaporates off the skin it takes body heat with it. Just like how the fan makes the rubbing alcohol evaporate quicker then water. Sweat doesnt actually have a smell but the odor that comes from your under arm starts out as a special fatty sweat that is produced from apocrine sweat glands. Bacterial that live on the under arm hair snack on this fatty sweat and produce waist, its this waist that smells. You may have herd that dogs don't sweat cause they don't have sweat glands, but they most definitively do sweat through sweat glands in their paws. How-ever only a small amount of heat is lost so they loose most of their body heat by panting. Which sends air over a moist tongue and moisture evaporates taking the dogs body heat with it. Mammals are the only animals that sweat. !?!DO DOGS SWEAT!?!
