So, the next part of the respiratory system anatomy and physiology is the trachea, the windpipe. Produces sound 4. This is present immediately after the nose. The left lung is composed of two lobes which are smaller than the right lung. Phlegm: Phlegm is a mucous secretion in the respiratory tract aimed to keep the tract moist and remove any dust particles entered into the tract by flowing towards the nose. Oesophageal pressure (Pes) is for technical and safety reasons substituted for pleural pressure. The ribs protect the lungs and allow the chest to expand and contract properly. The primary function of the respiratory system is gas exchange between the external environment and an organism’s circulatory system. Here is what happening during breathing: 1. We use cookies to ensure that we give you the best experience on our website.

Title: The Anatomy and Physiology of the Respiratory System 1 The Anatomy and Physiology of the Respiratory System 2 Functions of the Respiratory System. Air is taken in via the upper airways (the nasal cavity, pharynx and larynx) through the lower airways (trachea, primary bronchi and bronchial tree) and into the small bronchioles and alveoli … In older people and people with inflammation, the cilia activity is low, and hence phlegm accumulates a lot in their respiratory tract. This is the tract of the respiratory system in the throat. There are olfactory nerves that begin from the roof of the nose to form an olfactory bulb that carries the information of the sense of the odor into the olfactory lobe in the brain for perception. Filters inspired air 3. The lower airways – trachea, bronchi, and the lungs are considered to be in the lower airways. These are trapped in the nose. Anatomy & Physiology of the Respiratory System The respiratory system is situated in the thorax, and is responsible for gaseous exchange between the circulatory system and the outside world. This is a longer part of the track and is made of circles of cartilaginous bones with a capacity to contract and relax. They move in one specific direction only. Bullock, B. 3. (With permission from Thibodeau GA, Patton KT, 1996. It is composed of several essential structures contributing to its functionality.It involves the upper and lower airways, the lungs, the bony thorax, and the respiratory muscles. (1996). The alveoli are made up of two types of cells called Type I and Type II cells. The Respiratory System. The upper airways – these includes the nose, mouth, and the laryngo- pharynx and larynx. Oxygen supplier. 5. A variety of diseases can affect the respiratory system, such as asthma, emphysema, chronic obstruction pulmonary disorder (COPD), and lung cancer. These accessory muscles are evident during difficulty in breathing. Humidifier. b) Warming the passing air: When air enters the nose, the mucous wall in the nose gets in contact. See the difference between anatomy vs. physiology. Written by a team of expert academics and clinicians from a range of health backgrounds, the text uses a problem-solving approach, breaking down difficult A&P concepts through case studies, multiple-choice … Head of PICU, King Fahad Medical City. The nasal cavity is partly made of cartilaginous bone and skull bone. The importance of epiglottis during eating and drinking prevents aspiration of food and fluids into the lower airways. Relevant body systems are reviewed including cardiovascular and respiratory, followed by explanations of how the function of these systems affects vital signs. The accessory muscles involve the trapezius, strenocleidomastoid, and the scalene muscles. The job of the respiratory system is to keep the body constantly supplied with oxygen. The physiology of the respiratory system of the human body is not a problematic one mostly, but it is a delicate one, and if neglected or hampered in early life, it can reduce the life span and quality of life drastically. The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants.The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. It starts from the base of the skull and ends at the level of the 6th cervical vertebra (neck region). The group of organs that function to fortify blood with oxygen and remove carbon dioxide. They are very thin layered and a bit transparent. The circulatory system transports gases from the lungs to tissues throughout the body and vice versa. Mosby, St Louis.) The human respiratory system is a crucial facet of a vital, healthy body. The lungs are divided into two, the right and left lungs. 4. These ribs are attached to vertebrae and the sternum.
