SKIN: The skin is the biggest part of the human body. If opened up and laid out on a flat surface the human skin would cover up a surface area of 20–22 Sq. feet (full grown adult). The skin is also the fastest growing organ. One small piece of skin contains all sorts of blood vessels, nerves, nerve endings plus over 100 sweat glands and three million cells. On average the human skin weighs 10.895 kilo grams. Eyelids have the thinnest skin, with some light passing through them when they are closed. (That is why some of us are disturbed by the midnight light kept switched on by our roomie!!). The skin on the back is the thickest (Remember your mom’s beatings!!) , although the skin on feet and hands may be the toughest.

LIVER: The liver is the largest internal organ. It weighs 1.493 kilo grams. The liver has n number of functions is one of the most metabolically active organs of the human body. Its multitude roles include fighting off infection, neutralizing toxins, manufacturing proteins and hormones, controlling blood sugar and helping to clot the blood. Another, speciality of liver is that it has the capability to regenerate (Remember the regeneration of lizard tail into a new one when you cut off the old one). It only needs as little as 25 percent of the original tissue to do so. This make liver transplantation much more successful than transplantation of other internal organs. At its fullest, the liver holds approximately 10 percent of the blood in your body and pumps nearly 1.5 liters through itself per minute.

BLOOD VESSELS: Blood vessels may be tiny but they cover a lot of ground. The smallest blood vessels measure only five micrometers. But if we take all the blood vessels out of an average child and laid them out in one line, the line would stretch over 60,000 miles. An adult’s would be closer to 100,000 miles long. This is enormous!! The diameter of the earth is mere 7,917.5 miles.

The gluteus maximus is the largest muscle in the human body. It is large and powerful because it has the job of keeping the trunk of the body in an erect posture. It is the chief antigravity muscle that aids in walking up stairs. The hardest working muscle is the heart.

*Your femur, or thighbone, is the largest bone in your body. The head of your femur fits into your hip socket and the bottom end connects to your knee. The two bones beneath your knee that make up your shin are your tibia and fibula. Your upper and lower leg are connected by a h

DMD, the largest known human gene, provides instructions for making a protein called dystrophin. This protein is located primarily in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle. Small amounts of dystrophin are present in nerve cells in the brain.3 days ago


The thyroid gland is the largest endocrine gland in the body. It is located in the neck, below the larynx and in front of the trachea. It secretes thyroid hormone which maintains the metabolism of the body. 


The gastrointestinal tract is the largest endocrine organ in the body and the endocrine cells within it are referred to collectively as the enteric endocrine system.

The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves. Its name ("trigeminal" = tri-, or three, and - geminus, or twin: thrice-twinned) derives from the fact that each of the two nerves (one on each side of the pons) has three major branches: the ophthalmic nerve (V1), the maxillary nerve (V2), and the mandibular nerve (V3). The ophthalmic and maxillary nerves are purely sensory, whereas the mandibular nerve supplies motor as well as sensory (or "cutaneous") functions.[1] Adding to the complexity of this nerve is the fact that autonomic nerve fibers as well as special sensory fibers (taste) are contained within it.

There are 5 lumbar vertebrae (denoted as L1-L5) found in adult humans, and they are situated beneath the thoracic vertebrae, They are the largest, in terms of size, out of all the vertebrae because the lumbar vertebrae must be able to support the weight of the body when a person is standing due to the effects of ...
