PHYSIOLOGY OF LUNG IN HEALTH AND ILLNESS Presented by: Ligi Xavier Second year MSc nursing Govt. Anatomy & Physiology; Quiz: Lungs; All Subjects. Texture-- Spongy Color – Young – brown Adults -- mottled black due to deposition of carbon particles Weight-Right lung - 600 gms Left lung - 550 gms. 4. You have 2 lungs, and they take up most of the space inside your chest. 3. The Lungs: Anatomy & Physiology module provides a broad spectrum of adult male and pediatric normal anatomy cases with varying body morphologies to maximize training efficacy. The lungs contain 2–300 million alveoli with a total surface area, for gas exchange, of approximately 140 m 2. The circulatory system then helps distribute oxygen throughout the body. The … Learn exam 1 anatomy physiology respiratory system lungs with free interactive flashcards. Learn vocabulary, terms, and more with flashcards, games, and other study tools. GROSS ANATOMY OF LUNGS Lungs are a pair of respiratory organs situated in a thoracic cavity. Each lung has the following superficial features: The apex and base identify the top and bottom of the lung, respectively. The respiratory system organs oversee the gas exchanges that occur between the blood and the external environment. Nervous supply to the lung is via the pulmonary plexus within the mediastinum . The lungs are made up of large and small airways – the trachea being the largest and first of 23 generations of airways. We breathe in air rich in oxygen by the process called inspiration and breathe out air rich in CO2 by a process called expiration.. Lung cancer - The risk of dying from lung cancer rises with the number of cigarettes smoked per day, although duration of smoking is the strongest determinant. To maintain this elegant system of supply and demand during sustained aerobic exercise, our ventilation rate increases by about 300 to 400%. Anatomy of the Lung and Tracheobronchial Tree The chest has two lungs (a right lung and a left lung) (Fig. 5. In 1999, lung cancer was the most common form of cancer, accounting for 22 per cent (34,240 people) of all cancer deaths (Cancer Research Campaign, 2001). The right and left lungs are separated from each other by the mediastinum, where the heart, great blood vessels, bronchi, esophagus, and other organs are located. Each lung is composed of respiratory passages and alveoli. Oxygen supplier. Choose from 500 different sets of exam 1 anatomy physiology respiratory system lungs flashcards on Quizlet. They are conical in … Innervation. Physiology of Gas Exchange Inhaled air (oxygen) travels into the upper respiratory system (nose, nasal cavities, larynx) Down into the lower respiratory system via the trachea which splits at the carina into the right and left primary bronchi The primary bronchi and pulmonary artery/vein (which are from the heart) enter into the lungs at the hilum The tracheobronchial tree is the passage way from the mouth to the interior of the lung. Anatomy of the heart. These pulmonary capillaries create the respiratory membrane with the alveoli ((Figure)). It is responsible for the passage of air into our body, which is the source of life energy. Right and left lung are separated by the mediastinum. The costal surface of each lung borders the ribs (front and back). Humidifier. The lungs are situated within the ribcage enclosed by two pleural membranes (Fig 1). Elimination. CHAPTER 2Embryology, anatomy, and physiology of the lung Learning objectives To gain a basic understanding of the development of the lung To be aware of the common developmental lung abnormalities To understand the anatomy of the respiratory system which is relevant to clinical practice To be aware of the structure and function of the diaphragm… Healthy lungs are soft and light. College Of Nursing, Kottayam 2. Physiology of lung 1. Each lung has a base resting on the diaphragmand an apex extending superiorly to a … To really comprehend the effect of tobacco smoke on the lungs we need to take a look at both the anatomy—how the appearance of the lungs changes, and the physiology—how the function of a smoker's lungs differ from those of healthy lungs. The lung matrix of a neonate contains only small amounts of collagen; the elastin-to collagen ratio changes during the first months and years of life and affects lung stiffness and potential for overdistension and recoil Lung recoil increase with age in children over 6 years of age (more elastin) The size of the heart could be identical to that of a closed fist and it lies beneath the sternum and between the second and the sixth intercostal space. Occupying most of the space within the thoracic cavity, the lungs extend laterally … PHYSIOLOGY OF RESPIRATION inspiration- breathing in.. principle inspiratory muscles- the diaphragm & external intercostals. At the base of the thorax, separating it from the abdominal cavity, lies the diaphragm. The lungs are part of your respiratory system, the group of organs and tissues involved in breathing. Normally, during an inhale - the diaphragm contracts to pull downward and chest muscles contract to pull open the chest, which helps suck in air like a vacuum , and then during an exhale - the muscles relax, allowing the lungs to spring back to their normal size pushing that air out.
