cell organisation in the human body

Animal Organisation - Animals exhibit a complex body organisation which shows a very clear evolutionary trend. The complexity of animal organisation is seen with reference to features like cellularity, germ layers in the body wall, symmetry of the h..

The techniques of cultivating human cells in specific media and the techniques used in somatic cell genetics have enabled geneticists to understand the biochemical basis of the inheritance of many characters. Division of the human cells in the ..

Circulatory System - The transport system in animals is called the circulatory system. The materials are transported from one part of the body to another by a mass flow system which is the circulatory system. The animals, particularly the more advanced forms, have a higher metabolic rate...

The closed circulatory system can be represented as follows. Diagram showing inter-relationship between artery, vein and capillary The closed blood vascular system is a very well developed system This is so because, a) The organisms have a thick body wall to prevent the evaporation of wat..

In human beings, sexual reproduction takes place. Sexes are separate and hence they are known to exhibit sexual dimporphism. Males have sex organs called the tetes while the females have sex organs called the ovaries. Even in the external appearance, males and females show differences. So..

Health is considered to be the state of perfect functioning of body and mind, unhindered by diseases. Disease is the malfunctioning of the organism or part of it due to infection, inherent weakness or environmental stress, that upsets the normal physiological functioning of the orga..

Why are Organisms Composed of Cells? - All living organisms are composed of structural and functional units called cells. The body of a living organism may be composed of a single cell - as in unicellular organisms or many cells - as in multicellula..

Summary - All living organisms are composed of one or more cells. A cell is the structural and functional unit of life. The metabolic reactions in a living organism - can occur only in a delicately balanced environment. Through their unique chemical composition, cells ..

Cell Theory - Two German biologists M.J.Schleiden (1838) and Theodore Schwann (1839) proposed the cell theory (or cell doctrine), which unified the ideas prevailing at that period on the organisation in plants and animals. The cell theory states tha..

Introduction - The cells that make up our body are so small that you would fit over 200 of them on the full stop at the end of this sentenc..
