Hi there!
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale. Similarly, when you exhale, the diaphragm becomes dome shaped and the lungs will contract. This will create a high pressure area in your lungs and the air moves out.
Hope it helps!
Answer:
Respiratory system
Respiratory system is a complex system in which the organs are included which help us in the process of respiration . ( Respiration is the process in which the inhaled oxygen is used to produce energy ). The main organs that are included in this system are - Mouth and nose , Lungs ,Alveoli , Bronchioles etc .
Breathing movement
During breathing, the contraction and relaxation of muscles acts to change the volume of the thoracic cavity. As the thoracic cavity and lungs move together, this changes the volume of the lungs, in turn changing the pressure inside the lungs.
Process of Inspiration :- Diaphragm – flattens, extending the superior/inferior dimension of the thoracic cavity.
Process of Passive Expiration :- Diaphragm – relaxes to return to its resting position, reducing the superior/inferior dimension of the thoracic cavity.
