Explain the process by which inhalation occurs during breathing in human beings? |
| Answer» Breathing consists of two phases called inhalation and exhalation, it richs air comes out of the body. It occurs when the diaphragm moves up and the chest cavity becomes narrower. This creates a pressure on the air inside the lungs. As a result the air comes out of the lungs to the atmosphere due to lack of space inside. During this process, the chest wall expands out and away from the lungs. | |

Are the lips wastegial organ or if they have any use . |
| Answer» Who said Lips are a wastegial organ. In human body , nothing is wastegial organ.Lips have many purpose:1. During Food intake2. During articulation or speaking3. A tactile organ4. An erogenous zone.\xa0Clinical significanceAs an organ of the body, the lip can be a focus of disease or show symptoms of a disease:\tOne of the most frequent changes of the lips is a blue coloring due to\xa0cyanosis; the blood contains less oxygen, and thus has a dark red to blue color, which shows through the thin skin. Cyanosis is the reason why corpses sometimes have blue lips. In cold weather cyanosis can appear, so especially in the winter, blue lips may not be an uncommon sight.\tInflammation of the lips is termed\xa0cheilitis. This can be in several forms such as\xa0chapped lips\xa0(dry, peeling lips),\xa0angular cheilitis\xa0(inflammation of the corners of the mouth),\xa0herpes labialis\xa0(cold sore, a form of\xa0herpes simplex) and\xa0actinic cheilitis\xa0(chronically sun damaged lips).A child with\xa0cleft lip\tCleft lip\xa0is a type of\xa0birth defect\xa0that can be successfully treated with surgery.\tCarcinoma\xa0(a malignant cancer that arises from epithelial cells) at the lips, is caused predominantly by using tobacco and overexposure of sunlight. Alcohol appears to increase the carcinoma risk associated with tobacco use. It is most often a diffuse and often hyperkeratinised lesion, occasionally has the form of nodules and grows infiltratively, and can also be a combination of the two types. It more often occurs at the lower lip, where it is also much more malign. The lower lip carcinoma is exclusively\xa0planocellular carcinoma, whereas at the upper lip, it can also be\xa0basocellular carcinoma.\t | |

Why photosynthesis is a type of redox reaction |
|
Answer» Photosynthesis is a type of redox reaction because oxidation and reduction both are takes place in photosynthesis \tRedox reaction (oxidation-reduction reactions) are marked by the transfer of electrons. During oxidation, a substance tends to lose its electrons whereas, during reduction, a substance tends to gain electrons.\t\xa0Photosynthesis is a process in which plants containing chlorophyll convert the carbon dioxide into sugars in the presence of sunlight by a set of redox reactions.\xa0\tCalvin cycle represents a set of reactions which are used to remove electrons from water which are then used to turn carbon dioxide into organic compounds.\tRedox reactions during photosynthesis :It involves two major steps -\xa0\tThe first step is the oxidation in oxygen in water molecule in the presence of light2H2\u200bO → O2\u200b + 4H+The second step is the reduction step where hydrogen ions reduce the carbon in carbondioxide4H+ + CO2\u200b → (CH2\u200bO) + H2\u200b0The net reaction isCO2\u200b + H2\u200bO → (CH2\u200bO) + H2\u200bO |

What is respiration and mechanisms of respiratory system |
| Answer» Let us have a detailed look at the different parts of the respiratory system and their functions.Nose:The nose possesses a couple of exterior nostrils which are divided by a framework of cartilaginous structure termed as the septum. This is the structure that evenly separates the right nostril from the left nostril. Tiny hair follicles that cover the interior lining of nostrils acts as the body’s first line of defence against foreign pathogens. Furthermore, they provide additional humidity for inhaled air.Larynx: Two cartilaginous chords lay the framework for the larynx. They are situated at the point of joining the pharynx and trachea. It is also termed as Adam’s apple or the voice box. It is the portion which rises and falls during swallowing of food particles. It generates sound as air passes through the hollow in the middle.Pharynx:The nasal chambers open up into a wide hollow space termed as the pharynx. It is a common path for both air and food. It functions by preventing the entry of food particles into the windpipe. The epiglottis is elastic cartilage which serves as a switch between the larynx and the oesophagus by allowing the passage of air into the airway to the lungs, and food into the\xa0gastrointestinal tract.Trachea:The trachea or the windpipe rises below the larynx and moves down to the neck. The walls of trachea comprise C-shaped cartilaginous rings which give hardness to the trachea and maintain it by completely expanding. The trachea extends further down into the breastbone and splits into two bronchi, one for each lung.Bronchi:The trachea splits into two tubes termed as bronchi, which enter each lung individually. The bronchi are divided into secondary, tertiary, and to bronchioles which is again further divided into small air-sacs called the alveoli. The alveoli are minute sacs of air with thin walls, and single-celled manner. It enables the exchange of oxygen and carbon dioxide molecules into or away from the bloodstream.Lungs:Lungs are the chief centres of the respiration in humans and other vertebrates. They are located in the thoracic cavity of the chest near the backbone and on either side of the heart. They are the pair of large, spongy organs mainly involved in the exchange of gases between the blood and the air. Compared to the left lung, the right lung is quite bigger and heavier. | |
