Understanding Respiration

Understanding Respiration On basically Respiratory is a series of intake of oxygen through the respiratory system and the removal of oxidation residues in the form of oxygen carbon dioxide And steam water. Breathing includes process inspiration And expiration. Inspiration is income air outside to in body through tools Respiratory. Expiration is an expense air Respiratory from tool Respiratory. In some higher living creatures such as animal vertebrates And man, entry oxygen to in body happen through intermediary tools Respiratory. Respiration process taking place in three stage, between other following This. 1. Respiration External Respiration external is process exchange oxygen And carbon dioxide between air in atmosphere And air in in lungs. Matter This applies on animal the living in land. For animals Which his life in water, respiration external is the process of exchanging oxygen and carbon dioxide gases between air in a water medium And air in gill. 2. Transportation Gas Oxygen and Carbon Dioxide Freight or transportation gas consists on two process, that is oxygen transport from capillary lungs or capillary gill circulated to all over organism cells and the transport of carbon dioxide from organism cells to the lung capillaries or gill. 3. Respiration Internal Oxygen Which obtained from environment used on process combustion to produce energy, while the byproduct is carbon dioxide Which must issued from body. Process respiration internal often time referred to as respiration mobile, Because process respiration This happen in in cell, that is in the cytoplasm And mitochondria. Respiration internal or mobile happen through several stages, namely glycolysis, Krebs cycle, and electron transport (electron transfer). Respiration Organ On mammal, lungs consists from a number of wattle. Bronchi enters the lungs Then branching until Finally to part Which thin-walled vesicles , called alveoli, are always wet and contain many capillaries blood. Alveoli is place exchange oxygen with carbon dioxide. The number of alveoli in one lung is very large, reaching tens of millions to hundreds of millions. Amount alveoli Which Lots expand areas exchange gas in lungs. With thereby, surface lungs Which very wide possible oxygen uptake with freely. As Wrong One member mammal, man own lungs with characteristics like Which has stated in on. Amount the alveoli 300 million fruit, with wide if stretchedout around 70 m. With circumstances wide lungs like That, hence respiration become more efficient And acquisition oxygen will ensure life man. Alveoli own wall Which thin made of from epithelium layer flat. Lungs man limited by pleura Which very elastic. Thereby also with wall cavity part of the chest in, limited by pleura. In between pleura lungs with pleura chest cavity there is fluid intrapleural. Pressure intrapleural more low than air pressure outside. Matter This makes it easier income volume air to cavity chest. Before enter cavity chest, air enter to cavity nose. In here hair filtering nose particle dirt, dust, or small insects . Furthermore, air warmed, moisturized _ so that oxygen dissolved, And cleaned once again by the mucus (mucus) found on the surface wall cavity nose. Mucous membrane Which there is in throughout cavity very nose Lots contain fiber nerve and vessels blood. Circumstances This at a time to detect gas chemical Which originate from smells . In matter This nose role as sense organs . Furthermore, air Which has warm and moisture enters the pharynx, a long tube not enough more 10 cm. Pharynx is a link between cavity mouth, esophagus, and cavity nose. Although the pharynx is the meeting place channel digestion (esophagus), from mouth to stomach with channel air (trachea, from nose to lungs), no be found that problem cause food wrong come in to the throat or air come in to esophagus, cause be found mechanism reflex which arrange its distribution. If us swallow something, entrance way air to pharynx closed. Child throat or uvula fold to back and close section on pharynx. On the contrary If interesting breath, uvula move to place beginning. Thus , between channel Respiratory And channel digestion No each other bother. However, sometimes when We Eat while speak, food in a way not deliberate enter to channel Respiratory so that cause incident choked. Moment happen incident choking, body will try For emit return food Which enter in a way reflex. Mechanism swallow And breathe arranged that way appearance by valve epiglottis as well as movement to on by larynx when swallowing so that channel to cavity nose closed meeting And walk normal return. The next respiratory tract is the larynx . When swallowing, the epiglottis is attached to the larynx close And when breathe epiglottis open. By Because That, difficult once someone swallow food while talk. Larynx Also produce voice at the moment air exhaled from lungs. Voice Which is vibration air emerged from vibration tape voice Which transverse on hole larynx, helped by mouth and tongue. From larynx, air going to trachea (throat) Which arranged on bone rings vulnerable. In the end, trachea branching two become bronchi going to right lung And lungs left. In lungs, bronchi Still branching dichotomously _ become branches fine called bronchioles . From trachea to the alveoli there is around 23 time branching.
