Nose/Mouth then Pharynx, Trachea, Bronchus, Alveoli,and then reverse for exhalation. 10 marks please, yippee ki yay!

The first is surface area. The mammalian lung has a huge number pf alveoli compared to lung structures of reptiles and amphibians. The greater the surface area available for gas exchange, the more efficient will be the gas exhange.\n\nThe second requirement for gas exchange is assisted by the mamallian heart of four chambers as opposed to reptilian and many other hearts. There is an enormous amount of the circulatory system that passes directly to the pulmonary arteries and veins. Thus there is sufficient blood circulation in the lung area to remove oxygen and transfer it to the rest of the body.\n\nComparative biology will show far fewer alveoli in non-mammalian hearts (with the exception of birds). The other thing notable from compataive anatomy is that the mamallian heart (and that of birds) is a four chambered pump that does not mix unoxygenated blood with blood that has been oxygentated.\n\nSurface area and increased opportunities for deoxygenated hemoglobin to accept oxygen due to more efficient heart action.

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 upper respiratory tract also functions to warm and humidify the air you breath so this is one function that is lost. To counter this the air/oxygen mix should be warmed and humidified. If not the lining of the respiratory tract would become dried and damaged as a result.\n\nThe upper respiratory tract also serves to filter particles from the air so filters must be attached to the ventilator.

Greetings from inside the Yahoo Brain in New York City!\nHope you're catching the live webcast at: http://advision.webevents.yahoo.com/asktheplanet/brain.html !\n\nI thought there were 5 main branches of biology:\n\n1.  ZOOLOGY: the study of animals\n2. BOTANY: the study of plants\n3. MICROBIOLOGY: the study of viruses, monerans, and protists\n4. BIOCHEMISTRY: the study of the chemical nature of life\n5. ECOLOGY: the study of the interaction among organisms in ecosystems\n\nHope this helps!\n\n--J.

muscular system helps you move.....with out that you couldnt move anywhere......respiratory helps you breath.......circulatory helps the blood move through the body and other fluids get where they are going

ALVEOLI:\n The alveoli are the final branchings of the respiratory tree and perform gas exchange for the lung. The thin gas-blood barrier between the alveolar space and the pulmonary capillaries allows for rapid gas exchange. Oxygen and carbon dioxide diffuses through the alveolar epithelium and the capillary endothelium.\n\nThere are two types of alveolar epithelial cells. Type I cells thinly line the alveolar walls. Type II cells produce surfactant - a lubricant that reduces surface tension. \n\nSURFACTANT:\n Surfactant is any substance that acts to alter surface tensions, such as those in the lungs. This substance reduces the surface tension within the alveoli, preventing them from collapsing.\n\nInfant Respiratory Distress Syndrome is caused by a lack of pulmonary surfactant. The alveoli collapse and prevent the infant from breathing properly.

hmm... sites... can't think of any.\ni studied respiratory therapy, including perinatal and pediatric respiratory problems... i could give you some pointers or list of the common respiratory problems found in children and maybe you could type the key words and find out more about it. (well, i cannot list them all here... too many of them) if you want to know more, give specifics like how old is the child, what is your main concern etc.\n\nyou want to learn more about children or babies?

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

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.

Blood supplies oxygen to all the parts of the body, thus enabling all the organs and systems to continue to function. Without blood and the movement of it through your body, your body would shut down due to oxygen deprivation. The respiratory system provides the oxygen via breathing and then sends it everywhere via the cardio(heart) vascular(veins and arteries) system. Blood supplies the nutrients we eat via the digestive systems and removes all the wastes. The human body is an amazing invention if you really think about it and blood is the biggest part of the body and even counts as a body in homicide cases where the actual body can't be found. Good luck in your classes.

The trachea in reptiles is similar to that of higher vertebrates, with well-developed hyaline rings.  However, there is no mucociliary transport mechanism to aid the removal of foreign substances from the respiratory tract.  Furthermore, the absence of a diaphragm prevents the animal from coughing. \n\nThe lungs are similar to the avian-type system with a series of reticulated open-ended sacs and many capillaries in close proximity.  The cranial part of the reptile lung is the gaseous exchange portion, while the caudal part functions as an air sac.  The latter may act as a reserve of air during periods of apnoea. \n\nAlveolar macrophages are present in the reptilian lung, but may display poor bacterial removal if the animal is being kept below its optimal temperature. \n\nIn snakes, the right lung is larger than the left, and generally stretches from the heart to the kidney.  It may extend even further down to the cloaca in some aquatic snakes.  Some snakes have a tracheal lung on the dorsal aspect of the trachea, which enables the snake to breathe when the main lung is compressed by swallowed prey.
