Notes For All Chapters Biology Class 11 In the previous chapter, you have already learnt that the nervous system in the body, provides point-to-point coordination among the organs. The neural coordination is rapid, but short lived in nature. However, the nerve cells of not reach to each and every cell of the body. So, a […]

Notes For All Chapters Biology Class 11 The human body has several organs. These organs cannot perform their functions independently. In order to maintain homeostasis for the normal physiology of the human body, functions of these organs/organ systems in our body must be coordinated, so that they can work in proper manner. Topic 1 Nervous […]

Notes For All Chapters Biology Class 11 Topic 1 Musculature : Structure and Functions Movement Movement is defined as any visible change of position, exhibited either by the whole organism or any part of the body. It is one of the important characteristics of living organisms. The movement of living things are autonomic (self-sustained) while, […]

Notes For All Chapters Biology Class 11 Excretion is the removal of nitrogenous waste products and other metabolites from the animal body which is normally associated with the process of maintenance of osmibtic concentrations, i.e., osmoregulation within the body. Both excretion and osmoregulation are important for the maintenance of homeostasis, i.e., for keeping the internal […]

Notes For All Chapters Biology Class 11 Each and every cell of a multicellular organism require food, oxygen and vital components to survive. Simultaneously as a result of metabolism, cell also produces some useful and waste products. Substances that are useful, are transported to other cells, while harmful or waste substances are removed from the […]

Notes For All Chapters Biology Class 11 Cells continuously use oxygen (O2) for the catabolic reactions that releases energy from molecules, e.g., breakdown of nutrient molecules like glucose. Thus, O2 has to be provided to the cells constantly. Simultaneously, these reactions releases carbon dioxide (CO2), which is harmful, so it must be removed quickly and efficiently. […]
