Branches of Microbiology
There are various different branches of microbiology and these include the following: 1. Bacteriology- The study of bacteria 2. Mycology –The study of fungi 3. Phycology- The study of photosynthetic eukaryotes. (Algae- Seaweed) 4. Protozoology – The study of protozoa (Single-celled eukaryotes) 5. Virology- The study of viruses, non-cellular particles which parasitize cells. 6. Parasitology- The study of parasites which…

Useful Microorganisms
As decomposers, bacteria and fungi play an important role in an ecosystem. They break down dead or waste organic matter and release inorganic molecules. Green plants take these nutrients which are in turn consumed by animals, and the products of these plants and animals are again broken down by decomposers. Yeast is a single-celled fungus…

Harmful Microorganisms
Disease and decay are neither inherent properties of organic objects, nor are caused by physical damage, it is microorganisms that bring about these changes. We are surrounded by bacteria, viruses, and fungi. Many microorganisms cause diseases in cattle, crops and others are known for entering human bodies and causing various diseases. Examples of familiar human diseases…

Introduction to Microbiology
Microbiology is the study of a variety of living organisms which are invisible to the naked eye like bacteria and fungi and many other microscopic organisms. Although tiny in size these organisms form the basis for all life on earth. These microbes are also known to produce the soil in which plants grow and fix…

Respiratory System Functions
Inhalation and Exhalation The respiratory system helps in breathing (also known as pulmonary ventilation.) The air inhaled through the nose moves through the pharynx, larynx, trachea and into the lungs. The air is exhaled back through the same pathway. Changes in the volume and pressure in the lungs aid in pulmonary ventilation. Exchange of Gases…

Respiratory Tract
The respiratory tract in humans is made up of the following parts: Air is inhaled with the help of nostrils, and in the nasal cavity, the air is cleansed by the fine hair follicles present within them. The cavity also has a group of blood vessels that warm the air. This air then passes to…

Respiratory System Parts and Functions
Let us have a detailed look at the different parts of the respiratory system and their functions. Nose Humans have exterior nostrils, which are divided by a framework of cartilaginous structure called the septum. This is the structure that separates the right nostril from the left nostril. Tiny hair follicles that cover the interior lining…

What is the Respiratory System?
As defined above, the human respiratory system consists of a group of organs and tissues that help us to breathe. Aside from the lungs, there are also muscles and a vast network of blood vessels that facilitate the process of respiration.
