In short, the diaphrgm controls the size of the opening which lets the light through the lens.  The larger the diameter, the more light comes in, so that one would use a wider opening on a darker day.\n\n(Just to confuse you, you should know that the larger the number on the diaphragm, the smaller is the diameter.)

Chemoreceptors in the medulla, carotid arteries and aorta, detect the levels of carbon dioxide in the blood. To do this, they monitor the concentration of hydrogen ions in the blood, which decreases the pH of the blood, as a direct consequence of the raised carbon dioxide concentration.\n\nThe response is that the inspiratory centre (in the medulla), sends nervous impulses to the external intercostal muscles and the diaphragm, via the phrenic nerve to increase breathing rate and the volume of the lungs during inhalation.

Hiccups are a result of spasms of the diaphragm. The diaphragm is the dome-shaped respiratory muscle seperating the chest from the abdomen. It aids in breathing by moving up and down, sending air in and out of the lungs. Find a picture to get a better idea of how this works. Hiccups are an involuntary (meaning we don't make them happen or continue to happen, they do so on their own, just like breathing and our heart beating are involuntary) rapid closing of the vocal cord that causes the sound you hear, "hiccup!" Common causes of hiccups include eating too fast, indigestion and laughing a lot, thereby inhaling and exhaling air irratically.

Currently, the function of the appendix, if any, remains controversial in the field of human physiology. It has been known to cause the ability to process bark, leaves and other things of that nature.\n\nThanks for asking, that was fun to look up.

Lung\nFrom Wikipedia, the free encyclopedia\n\nThe lungs flank the heart and great vessels in the chest cavity. (Source: Gray's Anatomy of the Human Body, 20th ed. 1918.)\n\nThe lungs flank the heart and great vessels in the chest cavity. (Source: Gray's Anatomy of the Human Body, 20th ed. 1918.)\nAir enters and leaves the lungs via a conduit of cartilaginuous passageways — the bronchi and bronchioles. In this image, lung tissue has been dissected away to reveal the bronchioles.

In this image, lung tissue has been dissected away to reveal the bronchioles. (Source: Gray's Anatomy of the Human Body, 20th ed. 1918.)\n\nThe lung is the essential organ of respiration in air-breathing vertebrates. Its principal function is to transport oxygen from the atmosphere into the bloodstream, and to excrete carbon dioxide from the bloodstream into the atmosphere. This it accomplishes with the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs where gas exchange takes place. Lungs also have nonrespiratory functions.\n\nMedical terms related to the lung often begin with pulmo-, from the Latin pulmonarius ("of the lungs"), cognate with the Greek pleumon ("lung").\n\nRespiratory function\n\nEnergy production from aerobic respiration often requires oxygen and produces carbon dioxide as a by-product, creating a need for an efficient means of oxygen delivery to cells and carbon dioxide excretion from cells. In smaller organisms, such as single-celled bacteria, this process of gas exchange can take place entirely by simple diffusion. In larger organisms, this is not possible; only a small proportion of cells are close enough to the surface for oxygen from the atmosphere to enter them through diffusion. Two major adaptations made it possible for organisms to attain great multicellularity: an efficient circulatory system that conveyed gases to and from the deepest tissues in the body, and a large, internalised respiratory system that centralized the task of obtaining oxygen from the atmosphere and bringing it into the body, whence it could rapidly be distributed to all tissues via the circulatory system.\n\nIn air-breathing vertebrates, respiration occurs in a series of steps. Air is brought into the animal via the airways — in reptiles, birds and mammals this often consists of the nose; the pharynx; the larynx; the trachea; the bronchi and bronchioles; and the terminal branches of the respiratory tree. The lungs of mammals are a rich lattice of alveoli, which provide an enormous surface area for gas exchange. A network of fine capillaries allows transport of blood over the surface of alveoli. Oxygen from the air inside the alveoli diffuses into the bloodstream, and carbon dioxide diffuses from the blood to the alveoli, both across thin alveolar membranes. The drawing and expulsion of air is driven by muscular action; in early tetrapods, air was driven into the lungs by the pharyngeal muscles, whereas in reptiles, birds and mammals a more complicated musculoskeletal system is used. In the mammal, a large muscle, the diaphragm (in addition to the internal intercostal muscles), drive ventilation by periodically altering the intra-thoracic volume and pressure; by increasing volume and thus decreasing pressure, air flows into the airways down a pressure gradient, and by reducing volume and increasing pressure, the reverse occurs. During normal breathing, expiration is passive and no muscles are contracted.. [\n\nNonrespiratory functions\n\nIn addition to respiratory functions such as gas exchange and regulation of hydrogen ion concentration, the lungs also:\n\n    * influence the concentration of biologically active substances and drugs used in medicine in arterial blood\n    * filter out small blood clots fo

In most animals, the main job of the stomach is to break down large fat molecules into smaller ones, so that they can be absorbed into the intestines more easily.\n\n1. The frog has feeble, practically useless teeth unlike humans who use their teeth for mastication in digestion.\n\n2. Solid wastes from the frog's large intestine pass into the cloaca where both liquid and solid waste material leave the body by way of the cloaca and the cloacal vent.In humans liquid waste leave the body by way of the urethra. while solid waste leaves the body by way of the rectum through the anus.

Respiration is a process involving inhalation and exhalation of airs.As for inhalation, the muscles that are involved in it is the diaphragm and external intercostal muscles.During inhalation, the contration of diaphragm (lowered to the abdominal) increased the lungs' volume so that the pressure inside the lungs are lower compared to the atmosphere pressure.As for external intercostal muscles, it help by elavating the ribs cage upward(superior) and forward(anterior).The movement that is made is know as Bucket Handle movement.\n\nAs for exhalation, the muscles that are involved in it is the abdominal muscles and the internal intercostal muscles.During exhalation process, the abdominal muscles contrated and pushed the diaphragm upward, squized the lungs(decreasing the lungs' volume).Decrease in volume caused the pressure inside the lungs are higher than the atmosphere pressure and then we exhaled the air out.As for internal intercostal muscles, it draged the ribs cage downward(interior) and backward or inward(posterior).\nThe two muscles involved in exhalation process only participated only if the process is active.Mostly, the exhalation is a passive movement of the ribs cage due to the elasticity of the lungs and the alveolies.\nIf the person exhaling with force,then the muscles will participate in.\n\nHope this helps ya.\n(^^o)/

your diaphragm muscles contract to achieve both coughing and vomiting. of course vomiting includes stomach muscles also.

The diaphragm almost always works perfectly. When you inhale, it pulls down to help pull air into the lungs. When you exhale, it pushes up to help push air out of the lungs. But sometimes the diaphragm becomes irritated. When this happens, it pulls down in a jerky way, which makes you suck air into your throat suddenly. When the air rushing in hits your voice box, you're left with a big hiccup.

all three act together in the regulation of breathing.\n\nthe chemoreceptors are located at the aortic arch and functions as peripheral receptors that will send information about the level of oxygen and carbon dioxyde in the blood to the medullary center. The respiratory center in the pons and medulla will send information to the respiratory muscles.\n\nj receptors, located at the small bronchi is connected to the cranial nerve X (n. vagus). this is a form of autonomic regulation

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.
