\nRespiration:<\/strong> It is a process of release of energy from food substances such as glucose and fats under the control of enzymes, to carry out life processes, by the living organisms.
\nRespiration is essential for life as energy produced during this process is utilized by the organisms to carry out various biological activities.<\/p>\n
\nStructure of nasal chamber:<\/strong>
\nThe nasal chamber is divided into left and right chambers by nasal septum. Each chamber is divided into three regions –<\/strong><\/p>\n\n
\nTurbinates:<\/strong> The respiratory region of nasal chamber is marked by three nasal turbinates.These are Ethmoturbinate, nasoturbinate and maxilloturbinates.
\nFunction of turbinates: It increases the surface area, so that dust particles can be removed and air become humidified.<\/p>\n
\nAdam’s apple :<\/strong> It is a prominent elevation formed by the laminae of thyroid cartilage. It is more pronounced in male than female.<\/p>\n
\n<\/p>\n
\nThe function of lecithin film in the lungs is to decrease the surface tension and keeps the alveoli open.<\/p>\n
\n<\/p>\n
\nBreathing:<\/strong> It is the physical process of taking in oxygen and giving out carbon dioxide.
\nThe function of diaphragm: It helps in breathing by contracting and relaxing thereby increase and decrease the volume of thoracic cavity. During inspiration diaphragm flattens while during expiration it becomes dome – shaped<\/p>\n\n
\nInternal respiration:<\/strong> It is the transport of oxygen in the blood from the lungs to the cells and the transport of carbon dioxide from the tissue cells into the blood and to the lungs.<\/p>\n
\nRespiratory quotient (RQ):<\/strong> It is the ratio of CO2 output to O2 uptake. It is denoted by R.
\nR = Rate of CO2 output \/ Rate of O2 uptake
\nRQ for carbohydrate = 1.00
\nRQ for fat = 0.70
\nRQ for protein = 0.85<\/p>\n
