Respiratory System

This topic helps us understand two types of respiration based on the presence or absence of oxygen. It explains the aerobic and anaerobic modes of respiration with some notable differences in them.

This topic discusses the energy requirement of different organisms. It mentions the calorific value of the nutrients, such as carbohydrates, proteins, and fats, along with the formula used to calculate them.

This topic highlights the human respiratory system and its features. We will learn about the parts of the respiratory system and their functions. A brief note on the respiratory tract is also given here.

This topic explains the steps of glycolysis. It talks about fermentation, which is the incomplete oxidation of glucose. It briefs on lactic acid and alcoholic fermentation. It also mentions the events taking place in aerobic respiration.

This topic discusses the respiratory volumes and capacities and its different types. It mentions the representations of tidal, IR, ER and residual volumes and capacities, along with the methods to calculate them.

This topic explains that at altitude, the reduced oxygen content of the blood induces breathing instability, with periods of deep and rapid breathing alternating. It also mentions that this breathing pattern is called high altitude (PB).

This topic describes the process of respiration in plants and animals. It discusses the organs used for respiration by humans, animals, fishes and insects with pictures. It also mentions how plants respire through holes in their leaves.
