The document discusses the human respiratory system and the process of respiration. It describes the major organs involved, including the nose, pharynx, larynx, trachea, bronchi, bronchioles and alveoli. It explains that the respiratory system allows for the intake of oxygen and removal of carbon dioxide through the processes of inspiration and expiration. The document also outlines some common respiratory diseases and disorders like asthma, bronchitis, emphysema and pneumonia.
Respiratory system
The respiratory system allows humans to breathe and exchange gases. It consists of a series of organs arranged as an upper respiratory tract and lower respiratory tract. The upper tract includes the nose, sinuses, pharynx and larynx which warm, moisten and filter air. The lower tract includes the trachea, bronchi and lungs. In the lungs, oxygen passes into blood in alveoli and carbon dioxide passes out, through external respiration. The system allows oxygen to reach cells through internal respiration and provides oxygen for cellular respiration to produce energy.
Grade 8 - Respiratory System
This document describes the key parts and functions of the human respiratory system. It explains that air enters through the nose, where nasal hairs and mucus trap dust and pollutants. The air is warmed and humidified before passing through the pharynx, larynx, trachea, bronchi and bronchioles to reach the alveoli in the lungs where gas exchange occurs. Oxygen is absorbed into the bloodstream while carbon dioxide is released. The lungs and chest cavity are lined by pleura and breathing is facilitated by the diaphragm. The respiratory and digestive systems work together to provide oxygen and glucose for cellular respiration. Some common respiratory disorders are also outlined.

The lungs presentation
The lungs are the essential organs for respiration in air-breathing animals. In humans, the trachea divides into the two main bronchi that enter the roots of the lungs, continuing to branch into bronchioles and alveolar sacs made up of clusters of alveoli where gas exchange occurs. The principal function of the lungs is to transport oxygen into the bloodstream and release carbon dioxide, with differences in lobe structure between human and pig lungs.
The Respiratory System
The respiratory system allows us to breathe in oxygen and breathe out carbon dioxide. It has two main zones - the conductive zone which brings air to the lungs through the nose, mouth, throat, trachea and bronchi, and the respiratory zone where gas exchange occurs in tiny air sacs called alveoli surrounded by capillaries. In the alveoli, oxygen passes into the bloodstream and carbon dioxide passes out through the thin walls of the alveoli and capillaries. Diseases and injuries can damage the respiratory system, but exercise and avoiding pollution can help strengthen it.
Respiratory system
The respiratory system collects oxygen and releases carbon dioxide. Air enters through the nose and mouth then travels through the trachea and bronchi, which divide into bronchioles ending in alveoli. The alveoli are surrounded by capillaries that exchange oxygen and carbon dioxide through the thin alveolar walls. Oxygen is absorbed into the bloodstream and carried throughout the body by arteries while carbon dioxide is absorbed and travels through the bronchioles, bronchi, trachea and out through the mouth and nose. The diaphragm and rib muscles help draw air in and push it back out through inhalation and exhalation.

1) The document describes the structure and function of the lungs and respiratory system. It discusses how gas exchange occurs in the alveoli between inhaled air and blood in the pulmonary capillaries.
2) The diaphragm contracts and flattens during inhalation, increasing the volume of the thoracic cavity and lowering pressure inside the lungs. This causes air to flow into the lungs.
3) Diseases like pulmonary fibrosis, emphysema, tuberculosis, and asthma can impair gas exchange and respiration by damaging lung tissue, increasing diffusion distances, and reducing lung function. Regular breathing and ventilation are needed to maintain concentration gradients driving gas exchange.
Respiratory System
This chapter covered the anatomy and physiology of the respiratory system, including the organs and their functions. It discussed medical terminology related to the respiratory system and provided examples of pathological terms, diagnostic tests, and abbreviations. The objectives were to describe the respiratory system and analyze medical word parts and terms as well as identify abbreviations pertaining to respiration.

- 1. Therese Williams ANP 1130 Chapter 14-WORKBOOK MEDICAL TERMINOLOGY REVIEW Define the following terms. 1. Atelectasis: Incomplete expansion of collapse of part or all of a lung due to mucus, tumor, or a foreign body that blocks the bronchus. The lung is said to be atelectasis. Also known as collapsed lung. 2. Emphysema: Chronic pulmonary disease resulting in destruction of air spaces distal to the terminal bronchiole. 3. Tuberculosis: Lung infection caused by the bacterium mycobacterium tuberculosis and spread by air-borne droplets expelled by coughing. 4. Pneumothorax: Large volume of air that forms in the pleural space and progressively separates the two pleural membranes. 5. Asthma: Sudden onset of hyperactivity of the bronchi and bronchioles with bronchospasm (contraction of the smooth muscle). Inflammation and swelling severely narrow the lumen of the airways. 6. Ventilation: The bulk movement of gas into and out of the lungs. 7. Respiration: The process of gas exchange at the lungs or tissue sites. Oxygen and carbon dioxide are exchanged in the alveoli during external respiration. Oxygen and carbon dioxide are exchanged at the cellular level during internal respiration. 8. COPD:A general term for a grouping of diseases (including chronic bronchitis and emphysema) that effects the efficiency of breathing leading to difficulty of breathing on exertion. 9. Pleural effusion: Accumulation of fluid within the pleural space due to inflammation or infection of the pleura and lungs. 10. Tidal volume:Amount of air inhaled or exhaled with each breath under resting conditions
