Breathing and Exchange of Gases Quiz

Breathing and respiration are essential processes for all living beings, as they derive energy from it to perform various activities. The chapter on "Breathing and Exchange of Gases" in Class 11 Biology covers these processes in detail, focusing on the respiratory system and its disorders [3-5).

The respiratory system is responsible for the exchange of gases between the body and the atmosphere. The process of respiration involves the following steps:

1. Breathing or pulmonary ventilation: Oxygen from the atmosphere is drawn in, and CO2-rich air from the alveoli is released [4).
2. Diffusion of gases (O2 and CO2) occurs at the alveolar membrane [4).
3. Transportation of gases by the blood: O2 and CO2 are transported across different parts of the body [3).
4. Diffusion of O2 and CO2 occurs between blood and tissues [4).
5. The utilisation of O2 by the cells and release of CO2 (cellular respiration) [4).

The mechanism of breathing involves the events that occur during inhalation (in inspiration) and exhalation (in expiration) [4). Respiration is controlled by both the neurological and chemical systems, with the brain's respiratory centre situated in the medulla oblongata and pons [3).

The respiratory system can be subject to various disorders, such as:

• Asthma: A disease that involves the air volume left in the lungs following a forcible expiration [2).
• Tidal volume: The air volume expired or inspired during respiration, which is about 500ml in a healthy individual [2).
• Residual volume: The air volume left in the lungs following a forcible expiration [2).

The study of breathing and respiration in Class 11 Biology is essential for students to understand the fundamental processes that occur in living organisms and the various respiratory disorders that can occur. This chapter also covers the different respiratory organs in different organisms and the human respiratory system in detail [5).

Important questions for Class 11 Biology Chapter 17 Breathing and Exchange of Gases are compiled by subject experts to make students feel confident and able to solve any type of question asked from this chapter during the Biology paper [2). These questions are created after thorough research on previous years' papers, exam patterns, and difficulty levels of exams [5). It is advised for students to solve these questions before their exams to be confident and able to solve any type of question asked from this chapter during the Biology paper [5).
