is the skin. The skin
is the largest organ of the body. The color of the skin is also the primary determinant of the race where one particular person belongs.1.) A square inch of foreskin from circumcised baby takes only 3 weeks to grow skin that can cover 3 basketball
courts. The laboratory-grown skin is used in treating burn patients.2.) On the average, a human skin has an area of about 2.0 m² and weighs up to 3.4 kg and accounts for 12% of the body weight.
3.) With the aid of magnifying glass
, humans are more hairy than monkeys. The hairs are too tiny for the naked eye.
