During expiration, the diaphragm and intercostal muscles relax, causing the thoracic cavity to decrease in volume. This decrease in volume increases the pressure within the thorax, which pushes air out of the lungs. This process facilitates expiration by creating a pressure gradient that allows air to flow out of the lungs.
What else can I help you with?
What changes occur in the thorax during ventilation?
During ventilation, the thorax expands as the diaphragm and intercostal muscles contract, increasing the volume of the thoracic cavity. This expansion decreases the pressure inside the thorax, causing air to rush into the lungs to equalize the pressure. Relaxation of these muscles allows the thorax to recoil back to its original position, pushing air out of the lungs.
What happens to the pressure inside the thorax when you exhale?
When you exhale, the pressure inside the thorax increases slightly due to the contraction of the diaphragm causing a decrease in thoracic volume. This increase in pressure helps to push air out of the lungs.
How many joints in a thorax?
There are typically 12 pairs of ribs in the thorax, which means there are 24 rib joints in total in the thorax.
How the process of inhalation take place?
During inhalation (inspiration) the ribs move up and out. Volume in the thorax increases whilst pressure decreases. The diaphragm goes down and the intercostal muscles contract. Just to let you know, exhaling (expiration) is just the opposite to inspiration. :) - Hope I helped :)
Largest body part of a butterfly?
The largest body part of a butterfly is its thorax, which is located between the head and the abdomen. The thorax contains the muscles and organs necessary for flight.

What process do mammals use to breathe?
In mammals the muscles that participate in the breathing process are the diaphragm and the intercostal muscles. In respiratory insufficiency other muscles can help the respiration, the muscles of the shoulders, neck, thorax and abdomen. The diaphragm (exclusive of mammals) and the intercostal muscles can contract or relax varying the volume of the thorax (the compartment where the lungs are located). The changing of the thorax volume forces inhalation or expiration. When the thorax volume is increased an internal pressure lower than the atmospheric pressure (external) is created and gases naturally enter the lungs. When the thorax volume is lowered the internal pressure rises above the external pressure and the air is expelled from the lungs.
What are the factors for holding the lungs to the thorax wall?
Surface tension from pleural fluid, positive pressure, and atmospheric pressure on the thorax.

Hoe does the diaphragm help you breathe?
The diaphragm divides your torso into two parts. the upper part, the chest or thorax, houses the lungs. When the diaphragm pull down, it forces air into the lungs. Whenthe diaphragm pushes up, it forces air out of the lungs.l
What process changes the grain size of a metamorphic rock?
In order to decrease the pressure within our respiratory tract, we have to expand our container. Our container is basically our thorax. If we can expand our thorax, the air pressure within our thoracic cavity will fall, and air will rush into our respiratory tract. The diaphragm is our primary means to increase our thoracic cavity
What happens during inhalation phase of breathing?
Pressure within the thorax decreases and air is drawn into the lungs
What anatomical position is the head to the thorax?
the head is superior to the thorax. the thorax is inferior to the head.
What happens to the pressure inside the lungs as the volume of the thorax increase?
As your diaphragm expands, the pressure in your thoracic cavity decreases. Air rushes into the partial vacuum, and you inhale.
What increases the volume of the thorax?
Inspiratory muscles such as the diaphragm and external intercostal muscles contract to increase the volume of the thorax. This action lowers the intrathoracic pressure, allowing air to rush into the lungs during inhalation.
What body part are the legs and wings attached to?
The thorax. See the related link for more information.
