Human body
Intestines: These help in the digestion as well as absorption of food.
Liver: It is the largest gland in the body.  Its functions are 1. to secrete bile juice, which helps in the digestion of food.  2. to store excess of suger in the form of glycogen. 3. to manufacture red blood corpuscles,  and  4. to help in the production of urea.
Heart: Human heart contains 4 chambers.  The functions of the heart are, 1. to supply pure blood to all parts of the body, 2. to collect impure blood from the organs of the body and 3. to pump impure blood into lungs for purification.
Lungs: The main functions of lungs are 1. to purify the blood and 2. to supply oxygen to the blood.
Kidneys : those are a pair of bean shaped glandular organs, they are a part of the excretory system of human body.  They are two in number.  They filter the nitrogenous waste of the body from the blood and throw them in the form of urine.
Skeleton of Body: The human body is supported on an internal skeleton consisting of 206 long, short and irregular bones.  These are joined together in several modes.
Arteries are blood vessels carrying blood away from the heart.
Veins are the blood vessels which carry blood back to heart from different parts of the body.
Auricles are two upper chambers of the heart into which the blood comes from the veins.
Ventricles are the two lower chambers of the heart from which purified blood flows out through arteries.
Blood is a red coloured fluid circulating through the heart, arteries, capillaries and veins.  One cubic millimeter of normal blood contains about 50,00,000 red corpuscles and 6000 white corpuscles.  The red colour of the blood is due to the presence of  a pigment known as haemoglobin.  The arterial blood is of bright red colour and the venous blood is of dark red colour.  The total amount of blood is a body is equal to about one-twelfth of the weight of the body.
Photosynthesis:  Plants manufacture carbohydrates from carbon dioxide and water in the presence of sunlight and chlorophyll.  The process is called photosynthesis.
6CO2 + 6H2O           Light                  C6H12O6+O2
                                       Chlorophyll                  Carbohydrate
Green House Effect: To increase the heat of Earth’s surface is called Green House Effect.  It is caused mainly by the pollution. Co2 is the main pollutant in air.
Acid Rain: The acidic Oxides like SO2, NO2 present in atmosphere and reacts with water and forms HN3, H2SO4 types acids and it falls on the earth with rain.  This  is called acid rain.
Food Chain: Food chain is the process of to transfer the energy from one thing to another thing.  It is starts from Herbivorious and ends with decomposers.  
Herbivoriousà Primary Carnivorious à Secondary Cornivorious à Decompossors
Vitamins: Vitamins are invented by Phunk.  There are two types of vitamins.  Those are fat soluble vitamins and water soluble vitamins.  Vitamin B,C are called water soluble vitamins and A,D,E,K are called fat soluble vitamins.  Vitamins are cofactors of Enzymes.

Vitamin-A is present in cod, eggs, green vegetables, etc., It is essential for growth of the body and protects skin and other delicate parts of the body.  It prevents infection and keeps the eyes healthy. Its deficiency causes night blindness and stunted growth of the body.
Vitamin-B1 is found in yeast, green vegetables, etc. Its deficiency leads to beriberi and anaemia.
Vitamin-B2 is the mixture of about twelve components.  It is present in milk, butter, vegetables, etc.  This is very important for growth and blood.  The deficiency of this complex leads to subnormal growth, pellagra etc.,
Vitamin-C is present in vegetables,. Fresh fruits, Oranges and lemons etc., Human milk are also a good source of vitamin-C.  its deficiency causes scurvy.
Vitamin-D is present in shark liver oils, milk, butter etc., Its deficiency causes rickets in children.
Vitamin-E is found in green vegetables eggs etc., Deficiency of this vitamin causes sterility.
Vitamin-K is mainly confined to green vegetables. This vitamin maintains normal clotting of blood.
Vitamin-P is present in association with vitamin-C and its functions are closely associated with the same vitamin.  It helps the action of vitamin-C and keeps the blood capillary healthy.
Water: Most of the food contains water.  This constitutes 75 per cent of our body.  It helps the digestion and absorption of food.  It also maintains the temperature of body and removes waste products.
Balance diet: it consists of fats, carbohydrates, proteins, vitamins, mineral salts, in right proportions to provide the requisite calories.  It is required to be taken regularly and just sufficiently.
