What else can I help you with?
Do the muscles of the diaphragm relax during inspiration?
No, the muscles of the diaphragm do not relax during inspiration; rather, they contract. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and allowing air to be drawn into the lungs. This contraction is crucial for effective inhalation, and it is complemented by the action of the intercostal muscles.
Does diaphragm have any desiesses?
Yes, the diaphragm can be affected by disorders or conditions such as paralysis, diaphragmatic hernia, or diaphragm muscle weakness. These conditions can impact the ability of the diaphragm to properly contract and relax, leading to difficulties in breathing and other respiratory functions.
What tighten and get shorter when you inhale but relax and get longer when you exhale?
The diaphragm and intercostal muscles tighten and contract during inhalation, causing the rib cage to lift and expand, resulting in a shorter length. During exhalation, these muscles relax, allowing the rib cage to lower and return to its longer length.
What is able to move up and down for moving air in and out of lungs?
The diaphragm and intercostal muscles contract and relax to create changes in lung volume, allowing air to move in and out of the lungs through the trachea. This process is known as breathing or respiration.
What does the sheep diaphragm and human diaphragm have in common?
Both the sheep diaphragm and human diaphragm are dome-shaped muscles located beneath the lungs that help with breathing. They contract and relax to create negative pressure in the thoracic cavity, allowing air to enter the lungs. Both diaphragms also play a role in assisting with other bodily functions such as coughing and sneezing.
What stimulates the diaphragm?
The diaphragm is stimulated to contract and relax by the phrenic nerve, which originates from the cervical spine. This nerve sends signals to the diaphragm to contract, allowing it to move downward and create negative pressure in the chest cavity for inhalation, and then to relax for exhalation.

How and why air moves into and out of lungs when you inhale and exhale?
When you breathe in, your diaphragm will contract, causing your lungs to expand and suck in air. When you breathe out, your diaphragm will relax, causing your lungs to shrink and force out air.
What muscle contract during inhalation and what muscles contract during exhalation?
The intercostal muscles, (muscles between the ribs), contract.
Does exhalation occur when the diaphragm and rib cage muscles relax?
Yes, exhalation occurs when the diaphragm and muscles of the rib cage relax.
What tighten and get shorter when you inhale but relax and get longer when you exhale?
The diaphragm and intercostal muscles tighten and contract during inhalation, causing the rib cage to lift and expand, resulting in a shorter length. During exhalation, these muscles relax, allowing the rib cage to lower and return to its longer length.
How do muscles contract and relax?
muscles contract and relax by bring about movements.
What happen to diaphragm when you relax?
It becomes domed.
What happens to your diaphragm when you relax?
It becomes domed.
What two ways do muscles work?
They contract and relax
What is able to move up and down for moving air in and out of lungs?
