How does the thorax enable us to breathe?

the volume of breathing in increases and when breathing out it decreases, the pressure in Inhaling decreases and the Exhaling increases.


Which muscle is the prime mover for inhalation?

Diaphragm is the the prime mover for the inhalation. It is a dome shaped partition between the thorax and the abdomen. It gets some what flat as it contracts. The volume of the thorax increases. There by the air is pulled in the thorax.


How the diapharm helps the air go in and out of the lungs?

Your diaphragm is dome shaped structure. You need to see the same in cadaver. when your diaphragm contracts, it becomes some what flat. This increases the volume of thorax and air rush in.


What is the the function of the diaphragm?

In the body, the diaphragm is a curved sheet of smooth muscle which separates the thorax from the abdomen. When it contracts, the diaphragm flattens, which INCREASES the volume of the THORAX, which then EXPANDS the lungs. Contracting the diaphragm therefore is associated with breathing IN, NOT OUT. In Birth Control, a diaphragm keeps sperm from getting to your cervix and uterus and making you pregnant.

As a cell increases in size the a. metabolic rate increases. b. surface area to volume ratio increases. c. volume increases and the surface area increases. d. surface area increases and the volume d?

As a cell increases in size the volume increases much faster than the surface area. The possible answer is C.


What happens to the volume of mercury as the temperature increases?

The volume increases, which is why the mercury in a thermometer rises as the temperature increases.


What happens to its volume when the temperature of a gas increases at constant pressure?

The volume increases.


When the pressure of a gas increases at constant temperature its volume?

Temperature increases as pressure increases.


What is the process of inspiration in mammals?

lungs lol 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 happens to the intrapulmonary pressure when intrapulmonary volume increases?

Pressure increases as volume increases, granted the container stays the same.
