Breathing and Exchange of Gases NEET Mindmap Download PDF

Breathing and Exchange of Gases NEET Mindmap is an easy-to-understand visual study aid that helps NEET aspirants to learn how oxygen is inhaled and carbon dioxide is exhaled by humans. Breathing and Exchange of Gases is a chapter from Class 11 NCERT, and several direct questions are asked from this chapter every year in NEET Biology.

Breathing is a process of inhalation and exhalation, while gas exchange includes transport of oxygen to cells and the removal of carbon dioxide from the body. The NEET Mindmap of Breathing and Exchange of Gases visually explains the complete process of human respiratory system, the mechanism of breathing, gas exchange in the lungs and tissues, respiratory volumes, hemoglobin, and the regulation of respiration in a single image chart.

PW provides NEET mindmaps, NEET detailed notes, and important question sets that together help the students to study smarter and revise faster. Breathing and Exchange of Gases NEET Mindmap by PW can be used to learn all the above subtopics at once for better retention in mind, making the concepts clearer.

Breathing and Exchange of Gases NEET Mindmap

Breathing and Exchange of Gases NEET Mindmap of PW covers every important topic and subtopic which are mentioned in NCERT books. It provides a brief study of how the human respiratory system works and how the exchange of gases between the lungs and tissues takes place in humans.

• The human respiratory system include all the organs which are involved in inhalation and exhalation of air in the body. It consists of nostrils, pharynx, larynx, trachea, bronchi, bronchioles, and lungs. The air enters from nostrils and travels through the respiratory tract and finally reaches alveoli of lungs where the gas exchange takes place.

• The mechanism of breathing includes the movement of diaphragm and intercostal muscles. During inhalation, the diaphragm moves down which increases the volume of lungs and air gets filled in it. During exhalation, the diaphragm moves up and forces the air out of lungs.

• Gas exchange in alveoli and blood occurs through diffusion process. Oxygen moves from alveolar air to blood while carbon dioxide moves from blood to alveolar air. The movement of gases happens because of the difference in partial pressure of gases between alveolar air and blood capillaries.

• The respiratory volumes include tidal volume (TV), inspiratory reserve volume (IRV), and expiratory reserve volume (ERV). It gives the measure of air capacity in lungs in different phases of breathing.

• Hemoglobin is a red pigment present in blood that binds with oxygen and forms oxyhemoglobin. It transports the oxygen to the tissues in the body. It also carries carbon dioxide to the lungs.

• Regulation of respiration is maintained by respiratory center which includes medulla oblongata and pons region of the brain. The normal rhythm of breathing is disrupted by the feedback mechanism when the concentration of carbon dioxide in the blood rises.

Tricks to Learn Breathing and Exchange of Gases NEET Mindmap

The concepts involved in breathing and exchange of gases in the body can be a little tricky for students to memorize for NEET exam. Following are the easy methods which will help them learn faster with the help of Breathing and Exchange of Gases NEET Mindmap:

• Human Respiratory System – Learn in Flow: Keep the flow of air in mind from: Nostrils → Pharynx → Larynx → Trachea → Bronchi → Bronchioles → Alveoli. This can be done by visualizing the entire system with the help of the Breathing and Exchange of Gases NEET Mindmap.

• Mechanism of Breathing – Think of Balloon Movement: Imagine lungs as a balloon which expands during inhalation and shrinks during exhalation. This can help you remember the diaphragm and pressure changes easily.

• Gas Exchange – Remember “High to Low”: Remember oxygen and carbon dioxide always move from higher pressure to lower pressure region. Oxygen moves from alveoli to blood, and carbon dioxide moves from blood to alveoli.

• Respiratory Volumes – Link with Breathing Stages: Tidal Volume is normal breath, Inspiratory Reserve Volume is extra air you can inhale, and Vital Capacity is your total usable lung capacity.

• Hemoglobin – The Oxygen Carrier: Think of hemoglobin as a delivery truck that brings oxygen to tissues and picks up carbon dioxide.

• Regulation of Respiration – Brain as Control Room: Think of the medulla oblongata and pons as a control room which signals the diaphragm to breathe based on CO₂ levels.

• Use Mindmap Daily for Practice: Visualize the entire process once daily for better recall during tests using Breathing and Exchange of Gases NEET Mindmap by PW.
