I believe the ribs are there to protect our lungs, heart etc. When we breath in, what we are actually doing is telling our diaphragm to contract, which moves it in a downwards motion. This caused pressure in our lungs to lower which pulls in air.
The rib cage doesn't move!
Answer
When you breath in, the diaphragm, (the muscles underneith your rib cage) cause the ribcage to expaned (outward away from center) When you exhale, the diaphragm causes the ribcage to conract. (inward to the center)
Inward.
yes actually it does move because it moves out
describe the movement of the ribcage and diaphragm during inhalation and exhalation
When the diaphragm expands, it creates a vacuum in your lungs and sucks air."Inhaling" When the diaphragm retracts, it expels the air."Exhaling"
during inhalation diaphragm goes down and ribs goes up.
During inhalation the ribcage expands, and during exhalation the ribcage contracts.
no
If you Feel around the bottom of your ribcage the diaphragm is around there :)
The sheet of muscle at the bottom of the ribcage is the diaphragm.
The diaphragm is a convex shaped muscle (convex side within the chest cavity).When the diaphragm muscle contracts it flattens out and drops down out of the chest cavity making more room and creating a vacuum -- air then rushes into the lungs.When the diaphragm relaxes it moves back up into the chest cavity and expels the air on the lungs. During inhalation, the increased volume of the lungs causes the ribcage to expand. Inhalation - Diaphragm CONTRACTS and moves DOWN (to allow more space in the chest cavity for lungs to expand).Exhalation - Diaphragm RELAXES and moves UP (to force air out of the lungs).
It expands to allow the lungs to fill up with air.
the diaphragm helps hold air in and out it is located right below your ribcage. when you sing, it pulses and allows your air to hold for a long time without a breath. The diaphragm is a muscle starting in your back and running to your front below your ribcage. It completely separates the area within your ribcage from the area below. However it does have sealed portals through which vessels and other structures pass. By expanding your diaphragm -- your abdomen will rise because the diaphragm is expanding downward into the abdominal area -- you can create a partial vacuum which helps to draw air into your lungs. Conversely, by relaxing your diaphragm you let air out of your lungs.
That is correct - at the same time. the diaphragm contracts, pulling air into the lungs.
the diaphragm relaxes and that causes the ribcage to compress (get smaller) this pushes air out, and you have exhailed
The thoracic diaphragm, where its contraction assists inhalation and relaxation assists exhalation plays a main role in altering the lung's volume and air pressure inside, contributing to the process of respiration. Many other muscles are involved in both raising and lowering the ribcage, and any stomach muscles involved assist in exhalation.
The diaphragm contracts when you inhale, making the space in your ribcage (thoracic cavity) more spacious and drop in pressure. Air is therefor "sucked" in due to this pressure difference. When you exhale, the diaphragm relaxes, pushing air back out. Without the diaphragm, it would be difficult to "grasp" air and pull it into your lungs.
The lungs will expand and the diaphragm will pull down to let air come in. The ribcage will also expand out for more room.
