Mechanism of Breathing in Humans | Class 10 Biology | Lecture 4 | Full | Conceptual Science Academy

Описание: In this video, we explain the Mechanism of Breathing in Humans in a clear, detailed, and exam-oriented manner for Class 10 Biology students. This is Lecture No. 4, based strictly on the CBSE / State Board syllabus.

Breathing is a vital life process that involves the intake of oxygen (inhalation) and release of carbon dioxide (exhalation). In this lecture, you will understand how breathing occurs, the role of lungs, diaphragm, ribs, and intercostal muscles, and how changes in chest cavity volume and pressure help in breathing.

🔍 Topics Covered in This Lecture

Meaning of breathing

Difference between breathing and respiration

Mechanism of inhalation

Mechanism of exhalation

Role of diaphragm and ribs

Expansion and contraction of lungs

Importance of breathing in human life.
Comparative Explanation: Inhalation vs Exhalation
Inhalation:
Air enters the lungs.
Diaphragm contracts and moves downward.
Ribs move upward and outward.
Chest cavity volume increases.
Pressure inside lungs decreases.
Lungs expand.
Exhalation:
Air goes out of the lungs.
Diaphragm relaxes and moves upward.
Ribs move downward and inward.
Chest cavity volume decreases.
Pressure inside lungs increases.
Lungs contract.
This comparison table is very important for board exams, MCQs, and short answer questions.
