Digestive System Gross and Cool Facts! HOW LONG ARE YOUR INTESTINES? At least 25 feet in an adult. Be glad you're not a full-grown horse -- their coiled-up intestines are 89 feet long! Chewing food takes from 5-30 seconds Swallowing takes about 10 seconds Food sloshing in the stomach can last 3-4 hours It takes 3 hours for food to move through the intestine Food drying up and hanging out in the large intestine can last 18 hours to 2 days! Americans eat about 700 million pounds of peanut butter. Americans eat over 2 billion pounds of chocolate a year. In your lifetime, your digestive system may handle about 50 tons!! Menu

Respiratory System Gross and Cool Facts! Your lungs contain almost 1500 miles of airways and over 300 million alveoli. Every minute you breathe in 13 pints of air. Plants are our partners in breathing. We breathe in air, use the oxygen in it, and release carbon dioxide. Plants take in carbon dioxide and release oxygen. Thank goodness! People tend to get more colds in the winter because we're indoors more often and in close proximity to other people. When people sneeze, cough and even breathe -- germs go flying! Menu

Circulatory System Gross and Cool Facts! The body of an adult contains over 60,000 miles of blood vessels! An adult's heart pumps nearly 4000 gallons of blood each day! Your heart beats some 30 million times a year! The average three-year-old has two pints of blood in their body; the average adult at least five times more! A "heartbeat" is really the sound of the valves in the heart closing as they push blood through its chambers. Menu

Muscular System Gross and Cool Facts! You have over 30 facial muscles which create looks like surprise, happiness, sadness, and frowning. Eye muscles are the busiest muscles in the body. Scientists estimate they may move more than 100,000 times a day! The largest muscle in the body is the gluteus maximus muscle in the buttocks. Menu

Skeletal System Gross and Cool Facts! The human hand has 27 bones; your face has 14! The longest bone in your body? Your thigh bone, the femur -- it's about 1/4 of your height. The smallest is the stirrup bone in the ear which can measure 1/10 of an inch. Did you know that humans and giraffes have the same number of bones in their necks? Giraffe neck vertebrae are just much, much longer! You have over 230 moveable and semi-moveable joints in your body. Menu

Endocrine System Gross and Cool Facts! The endocrine system is under the control of the nervous system You've got over 30 of these amazing hormones busily orchestrating and regulating such things as: when you feel hungry or full how you sleep your body temperature how you break down and utilize the food you eat and whether you are fat or thin when you start puberty and how long it takes how you handle stress how much adrenaline you have in an emergency situation even how and when you grow It also makes you smelly, greasy, and gives you the ability to mother or father a child Menu

Immune System Gross and Cool Facts! A weakened immune system is NOT a cause of the common cold. The No. 1 way to boost your immune system is reducing stress Laughing lowers levels of stress hormones and strengthens the immune system. Six-year-olds laugh an average of 300 times a day. Adults only laugh 15 to 100 times a day. Vitamin C helps, too, if you don’t pee it out Over 90% of diseases are caused or complicated by stress. Menu

Integumentary System Gross and Cool Facts! People with higher number of moles tend to live longer than people with lesser number of moles. The fastest growing nail is on the middle finger. And the nail on the middle finger of your dominant hand will grow the fastest of all. Why is not entirely known, but nail growth is related to the length of the finger, with the longest fingers growing nails the fastest and shortest the slowest. Human hair is virtually indestructible. Aside from it’s flammability, human hair decays at such a slow rate that it is practically non-disintegrative. Hair cannot be destroyed by cold, change of climate, water, or other natural forces and it is resistant to many kinds of acids and corrosive chemicals Menu

Nervous System Gross and Cool Facts! The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain. The brain is much more active at night than during the day. The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping. Just for fun! Menu

Reproductive System Gross and Cool Facts! Every human spent about half an hour as a single cell. Babies are born with 300 bones, but by adulthood the number is reduced to 206. A woman never runs out of eggs.  At birth she has between 1 and 2 million potential eggs (follicles) and by puberty has 300,000 to 400,000 viable eggs (follicles) that can be fertilized. The male scrotum hangs outside the body since the internal body temperature is too high and will kill the sperm. About 500 million sperm mature every day in a healthy male. Menu

Excretory System Gross and Cool Facts! Approximately 75% of human waste is made of water. Earwax production is necessary for good ear health. While many people find earwax to be disgusting, it’s actually a very important part of your ear’s defense system. It protects the delicate inner ear from bacteria, fungus, dirt and even insects. It also cleans and lubricates the ear canal. Tears and mucus contain an enzyme (lysozyme) that breaks down the cell wall of many bacteria. Menu
