In the process of 'expiration' how do diaphragm and ribs move??
370241
in expiration the diaphagm moves upward in ribs moves inward

Incorrect, Inspiration is; diaphragm, external intercostal.  Expiration is; abdominal, internal intercostal.\nScalene is in the neck, not used for inspiration,

You can increase the lung capacity but the rib bones will stay the same size. :D

CO2 is carried through the blood in the body to the lungs to be exhalated.

Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale. \n\nThe diaphragm's job is to help pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. As the diaphragm contracts and relaxes, breathing takes place. When the diaphragm contracts, oxygen is pulled into the lungs. When the diaphragm relaxes, carbon dioxide is pumped out of the lungs. \n\nThese links should help.

Your diaphram is located right above your stomach.  When you breath, you breath from you diaphram.  So, when you breath in, the air push down on your diaphram, cause pressure on you stomach.  This is what pushes your stomach out.  When you release the air, your diaphram pulls up, creating lease pressure on the stomach, making it go in.  I learned all of this in Choral!  I hope I could be of some help.

A gas moves from a high pressure to a low pressure. When you breathe in, the partial pressure of oxygen in the lungs is higher than in the blood. Therefore the oxygen will move from the lungs to the blood. The exact opposite is true for carbon dioxide.

That is the diaphragm. It is a muscle that helps breathing.

That's spelled "respiratory" system, not "respitory" ;-)\n\nYou'll find an explanation of how your respiratory system works here:\n\nhttp://sln.fi.edu/biosci/systems/respiration.html\nor here: http://yucky.discovery.com/flash/body/pg000138.html\nor a slightly more technical explanation here: http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/P/Pulmonary.html

Oxygen enters through the mouth and nose (nasopharynx) and moves down into the trachea and into the lungs. Oxygen and Carbon Dioxide are exchanged in the lungs at the Alveoli. Oxygen enters into the blood stream and Carbon Dioxide leaves the blood stream to be expelled by the exhalation of the lungs. The Oxygenated blood travels from the lungs to the heart, the heart then pumps the Oxygen rich blood into the arteries which take that blood away from the heart and circulate it through the rest of the body. Veins Then come back to the heart carrying oxygen-depleted blood where they are pumped through the heart to the lungs where they get more Oxygen and once again travel back to the heart to be pumped back to the rest of the body. That completes the circuit.

Your lungs inflate because your chest expands (intercostal muscles flexing) and the diaphram flexes. This creates negative pressure inside the pleural cavity and causes the lungs to inflate (the actions of the chest wall and diaphragm essentially creates a vacuum and air tries to enter through the nasal or oral cavities, to reduce the vacuum)

you could have just strained a muscle in your rib cage... breathing requires the movement of a lot of these muscles, especially breathing out, so that action could be causing a compression or stretch on the muscle. Just relax and try not and do anything to make you breath really deep or forcefully and hopefully it will go away...

cus ur diaphram moves up and down and kinda has a seisure

Wow, so there are a few answers to this:\n\n-The apnuestic center in the brain controls repirations.\n\n-The diaphragm is the muscle that helps move the lungs up and down. \n\n-The sudden drop in negative pressure in our chest cavity that signals our lungs to take a breath in once we have enhaled the last breath out.

the only thing that ever has worked for me was that old trick of holding your breath for 20-30 seconds.  Other than that, I really don't know.  It's your diaphragm having spasms....weird!

Respiration is performed using tracheae, air-filled tubes which open at the surfaces of the thorax and abdomen through pairs of spiracles. The spiracle valves only open to allow oxygen and carbon dioxide exchange. The tracheoles, found at the end of the tracheal tubes, are insinuated between cells and carry oxygen throughout the body. \n\nI hope this helps.

You can learn a lot about breathing from the article about it on Wikipedia.  The link is listed in the Source section.\n\nHere's part of the entry:\n\n"Breathing is only part of the process of delivering oxygen to where it is needed in the body. Breathing in, or inhaling, is usually an active movement, with the contraction of chest and diaphragm muscles needed. At rest, breathing out, or exhaling, is normally a passive process powered by the elastic recoil of the chest, similar to a deflating balloon. The process of gas exchange occurs in the alveoli by passive diffusion of gasses between the alveolar gas and the blood passing by in the lung capillaries. Once in the blood, the heart powers the flow dissolved gasses around the body in the circulation."\n\nSo the muscles in the chest and the diaphragm that brings the air in, while exhaling is just the lungs deflating.
