Inhalation - Wikipedia
WEBInhalation (or inspiration) is the process of drawing air or other gases into the respiratory tract, primarily for the purpose of bringing oxygen into the body. It is a fundamental physiological function in humans and many other organisms, essential for sustaining life.

WEBJan 8, 2024 · Inhalation and exhalation are how your body brings in oxygen and gets rid of carbon dioxide. The process gets help from a large dome-shaped muscle under your lungs called the diaphragm.
Physiology of How Breathing Works - Verywell Health
WEBFeb 26, 2024 · Breathing involves a complex system of nerves, respiratory muscles, and airways that work in tandem to draw oxygen into the lungs during inspiration (inhalation). The inhaled oxygen is then transferred to red blood cells, which the heart pumps to tissues throughout the body.
How the Lungs Work What Breathing Does for the Body
WEBMar 24, 2022 · When you breathe out, or exhale, your diaphragm and rib muscles relax, reducing the space in the chest cavity. As the chest cavity gets smaller, your lungs deflate, similar to how air releases from a balloon. At the same time, carbon dioxide-rich air flows out of your lungs through the windpipe and then out of your nose or mouth.

WEBAug 31, 2023 · Breathing is one of the four components of respiration, the other three being gas diffusion, gas transport and regulation. The pathway towards the lungs is provided by airways and together, these components form the respiratory system, which is located inside the thoracic or chest cavity.
22.3 The Process of Breathing – Anatomy & Physiology
WEBPulmonary ventilation consists of the process of inspiration (or inhalation), where air enters the lungs, and expiration (or exhalation), where air leaves the lungs. During inspiration, the diaphragm and external intercostal muscles contract, causing the rib cage to expand and move outward, and expanding the thoracic cavity and lung volume.

WEBMar 24, 2022 · Your lungs are the pair of spongy, pinkish-gray organs in your chest. When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.
