When the diaphragm contracts, <u>it flattens out.</u>

The diaphragm is a thin layer of skeletal muscle that is seen below the lungs. It is seen at the chest base and it helps to separate the chest from the abdomen. The contraction and relaxation of the diaphragm increase and decrease the thoracic volume which allows the air to enter and exit the lungs.

The contraction of the diaphragm increases the thoracic volume which forces the air to enter the lungs. This process is called inhalation. The diaphragm in its resting state appears dome-like and when it goes back to its resting state it pushed the carbon dioxide-rich air out. This is called exhalation.

The diaphragm is made up of fibrous tissue and skeletal muscles. It has a central tendon that anchors the diaphragm to the ribs. It also has 3 large openings they are esophageal opening, aortic opening, and caval opening. Some smaller ones are also present that allows the nerves and vessels to pass through. The actions of the diaphragm are controlled by the right phrenic nerves and left right phrenic. The inferior phrenic arteries supply blood to the diaphragm.

When molecules move down their concentration gradient, they move from where they are to where they are . Diffusion across a biol
IRINA_888 [86]

Answer:

they move from where they are more to where they are less.

Diffusion across a biological membrane is called passive diffusion.

Explanation:

When any molecules move across the cell membrane down their concentration gradient so they move from the area where their concentration is more to the area where their concentration is less and this process is called diffusion.

Diffusion across a cell membrane or biological membrane is called passive transport because no energy is needed to transport the molecules across the membrane as diffusion occurs along the concentration gradient.
