In this article we will discuss about some physico-chemical principles which plays a great role in physiology with the help of suitable diagrams. Also learn the physiological importance of each physico-chemical principles. 1. Filtration: Filtration is the process by which un-dissolved particles are separated from a liquid through a membrane as a result of a mechanical force (filtering force). It [...]
In this article we will discuss about some chemical compounds like acid, base and buffers. Acid and Base: An acid may be defined as a substance which, when dissolved in water, produces hydrogen ions [H+] or in other words, it is the compound of electronegative element with ionisable hydrogen [H+]. Similarly a base or alkali is a substance which produces [...]
The structure of atoms of some elements as shown (Fig. 3.9) indicate each element has a distinctive number of protons and electrons. The atom of all elements (103 known) is composed of the smallest and elementary particles. Neutrons, protons and electrons are the elementary particles. The neutron and proton occur in the centre of an atom where they form an [...]
