Elements are composed of chemical substances which are distinguished by their atomic number. In total there are 117 elements out of which 94 occur naturally on Earth. Human body is made up of different chemical elements. These elements are needed for several chemical reactions in the body to produce energy. There are several metabolisms which require these elements in different organs of human body.

There are almost 78 organs in a human body which vary according to their sizes, functions or actions. An organ is a collection of millions of cells which group together to perform single function in a human body. The cells in these body organs are highly specialized and formed for all the necessary actions for some specific time. Out of these 78 organs of a male or female body, skin is the largest or biggest organ with respect to its size and weight. The mojor or prerequisite human organ is the brain which handles all the functions and actions of a human body. Other top ten or 10 human body organs are given in the following list with names and functions.

	Skin is the largest or biggest human body organ. The average weight of skin in human body is about 10,886 grams which varies according to the size and weight of human being. Human skin is made up of different ectodermal tissues and it protects all the inner body organs like liver, glands, stomach, heart etc. Other functions are heat regulation, interaction with atmosphere, protection from diseases, absorption and sensation.
	Liver is the second largest organ of male or female human body. Its average weight in a normal human body is 1,560 gms. The liver recieves blood full of digested food from the gut. It stores some foods and delivers the rest to the other cells through blood. The other function of liver is to change the left material into harmless waste called urine.
	Brain is the third largest and major organ of human body. Its average weight in a normal human body is 1,263 gms. The brain controls the actions of all the body parts. There are about 100 billion cells in human brain which make about 100 trillion nerve connections with nerve cells for messaging. Medulla oblongata, Midbrain, Hind brain, Cerebellum, Spinal cord and Venticle are some of the major parts of a human brain.
	Lungs is the fourth biggest organ of human beings body. The average total weight of the right and left lung in a normal human body is about 1,090 gms. The major function of lungs is to inhale oxygen and exhale carbon dioxide out of the red blood cells. The lungs can hold a total of upto 5 litres of air. The adult lungs have an internal area of over 90 meters, that is about half the area of a tennis court.
	Heart is the fifth largest human body organ which is prerequisite for a living human being. The major function of the heart is to pump the blood to every part of the body to deliver the energy to every body cell. In males the average weight of heart is 315 gm while in females this weight is about 265 gms. Ventricles, atrium and aorta are some of the main parts of a human heart.
	Kidneys is the sixth largest organ in every human body. There are two kidneys in every human being and the average weight of both the kidneys is about 290 grams. The major function of a kidney is to separate the waste amterial by filtering the blood. Both these kidneys filter our blood 50 times a day. If one kidney stops working the other will enlarge and do the work of two.
	Spleen is 170 grams heavy and it is the seventh largest or heaviest organ of the human body. It forms the red blood cells pulp and white blood cells pulp. Therefore it is helpful in making the blood and increasing the immunity of the human being.
	Pancreas is the eighth largest human organ with an average weight of 98 grams in human body. It is one of the most important gland which produces several hormones including insulin, glucagon, and somatostatin. The pancreas is a dual-function gland, having features of both endocrine and exocrine glands.
	Thyroid is the ninth biggest one in human organs system. The average weight of thyroid gland in human body is 35 grams. It is the largest gland in the human body. The function of this gland is to produce thyroxine and triiodothyronine hormones.
	Prostate is the tenth largest human organ gland with a weight of 20 grams. It is the

	Femur is the largest and longest bone in human body. It forms the upper part of human leg. Its average length in adult male is 50.50 centimeter. This bone is also found in mammals, reptiles and vertebrates i.e frog, lizards, amphibians etc. Femur is Latin word which means thigh hence it is also known as thigh bone.
	Tibia is the second largest bone in the human body and no doubt the strongest bone of human body because it bears the body weight of person. It forms the inner-lower part of human leg. The average length of tibia is 43.03 CM. Tibia is Latin word which means an ancient type of musical instrument. Shin bone and shank bone are other names of Tibia.
	Fibula (also known as Calf Bone) is located in the outer-lower part of human leg. Fibula is the third largest bone in the human body. Fibula along with Tibia forms the lower part of human leg as it is located on the lateral side of Tibia. It is relatively weak and thin as compared with Tibia. The average length of tibia is 40.50 CM.
	Humerus bone connects shoulder with elbow in human arm. It is a long bone which consists of three parts i.e. upper extremity of Humerus, body of Humerus and lower extremity of Humerus. Humerus forms the upper part of human arm and many important muscles are attached with it. The average length of tibia is 36.46 CM.
	Ulna forms the inner-lower part of human arm. This fore-arm bone along with radius completes the lower part of human arm. Its average length in 28.20 Cm. In simple words it connects elbow with hand. It is a long and narrow bone with many muscles attached with it.
	Radius is a long bone which forms the outer-lower part of human arm. It is on the lateral side of Ulna and its length is 26.42 cm. Radius is also found in some four-leg animals as lower part of forelimb. Like Ulna it connects hand with elbow.
	7th rib is part of the 24 ribs found in a human body. The average length of 7th rib is 24.00 CM. Ribs are basically found in Vertebrates and they support the upper body of vertebrates.
	8th rib: These long and curved bones are considered as the basic structural part of human body. 8th rib is the part of 12 pairs of ribs in human body. The average length of 8th rib is 23.00 CM.
	Innominate bone is also called hipbone or half pelvis. It is the 9th largest bone in human body. Its average length is 18.50 Cm. Innominate bone is either of the two bones that form the sides of the pelvis, consisting of three fused components, the ilium, ischium, and pubis Nontechnical name hipbone.
	Sternum is the tenth largest bone in human body and its average length is 17.00 Cm. It is also called breastbone and it is found in both males and females with the same length. Sternum is a long, flat bone located in the center of the chest, serving as a support for the collarbone and ribs.
