The size of our eyes DOES (!) change, but it reaches pretty quickly the size of an adult, as actually our head (at the age of 10 or 12). By the way, if the eyes do not stop growing, person gets short sight.

Body weight may be divided into three types: bones, muscle and fat. In a healthy female of average weight, bones make up 12 percent of total body weight, muscle/lean tissue about 35 percent and body fat about 27 percent. The remaining body weight is skin, connective tissue, tendons, blood, organs and so forth.\n\nThe number of muscles in the human body varies from about 656 to 850, depending on which expert you consult. No exact figure is available because there are a variety of opinions about what constitutes a distinct muscle (versus a part of a complex muscle). Also, there is some variability in muscular structure between individuals.

Most of the human body is made up of water, H2O, with cells consisting of 65-90% water by weight. Therefore, it isn't surprising that most of a human body's mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.\n\nOxygen (65%) \nCarbon (18%) \nHydrogen (10%) \nNitrogen (3%) \nCalcium (1.5%) \nPhosphorus (1.0%) \nPotassium (0.35%) \nSulfur (0.25%) \nSodium (0.15%) \nMagnesium (0.05%) \nCopper, Zinc, Selenium, Molybdenum, Fluorine, Chlorine, Iodine, Manganese, Cobalt, Iron (0.70%) \nLithium, Strontium, Aluminum, Silicon, Lead, Vanadium, Arsenic, Bromine (trace amounts)

This is a good question. And I have been sitting here for a minute trying to figure out how to reply to it. Although I do not know the answer, I am going to look over the net, and do a search on Google, and Yahoo, and other sites and try to find out. I wish I knew what the answer was because I think a question like this deserves the answer. I am wonder how many other people would benefit from the answer. I am glad you asked this question, as it has really got me thinking............. thanks again!!!\n\n\n\nPS, this question reminds me of other questions I have seen in my lifetime, which I still have yet to come up worth an answer. Maybe you might know the answer to them............\n\n\n1.If you cut one head off of a two headed man, have you decapitated him? \n2.What is the maximum height of a short man?\n3. When does a fertilized egg develop into a person?

Our skin is the largest organ of our body. Skin serves several functions: it guards the underlying organs and muscles, it regulates our body temperature, it provides our sense of touch and it synthesizes vitamins D and B.\n\nThe skin includes parts like our hair and nails. In addition, there are several layers to skin, e.g., the epidermis and the dermis. Skin accounts for 15% of our body weight so you can see why it's called the largest organ in our body.\n\nThe above is basic information and you can already see how complex skin is. So there's lets to research and talk about when you're talking about skin.\n\nHope this helps.
