The lungs are wrapped with what is called pleura which allows the layers of the lungs to slide smoothly as it expands and contracts during respiration. 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. Bronchi further divide into smaller branches as bronchioles, which almost extend into the alveoli of the lungs. Save my name, email, and website in this browser for the next time I comment. The airways The airways branch a total of 23 times, creating a tree-like structure that ends in the alveoli, where the exchange of oxygen (O2) and carbon… Respiratory System Functions 1. These accessory muscles are evident during difficulty in breathing. The respiratory system helps in the safe exchange of gases from the outer atmosphere to inside the body. 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. The respiratory system includes the lungs. Air Distributor ; Gas exchanger ; Filters, warms, and humidifies air ; Influences speech ; Allows for sense of smell; 3. 4. It is responsible for sound and is made of cartilage. Lippincott Williams & Wilkins. These are trapped in the nose. (1996). Humidifier. Applied Anatomy and Physiology: the structure and functions of the cardio-respiratory system 7 1.2 The cardiovascular and respiratory systems 7 Applied Anatomy and Physiology: anaerobic and aerobic exercise 8 1.3 Energy and energy sources 8 Applied Anatomy and Physiology: the short-term effects of exercise 9 Sometimes a person uses his abdominal muscles when there is an obstruction in the airway. During inhalation, the respiratory muscles contract and the diaphragm is pushed downward. The disorders of the respiratory system are many but are not fatal on an instant basis. Pathophysiology: Adaptations and Alterations in Function 4th Edition. In this lesson, we will explore its function and physiology. a) Sense of smell: Olfactory function is one of the key functions of the nose. See the difference between anatomy vs. physiology. Next Structure of the Respiratory System. They are large sac-like structures (balloon-like). The purpose of these structures is to filter and humidify the air that is inhaled. Filters inspired air 3. They are very delicate to sharp objects and get punctured easily on an injury. Cardiovascular System – Anatomy and Physiology, Diary Of a COVID Nurse: The Fear and The Hope, The Importance of Nurses Being Diagnosed for Mental Health Issues, NCLEX-RN: Fluids and Electrolytes Questions with Rationale, Thinking Like a Nurse: The Critical Thinking Skills in the Nursing Practice. The bronchi on the other hand are comprised of lobar bronchi, tertiary bronchi, terminal and respiratory bronchioles, alveolar ducts and the alveoli – which is the gas-exchange unit of the lungs.

Here is what happening during breathing: 1. It is responsible for the passage of air into our body, which is the source of life energy. Written specifically for respiratory care students in an easy-to-understand format, Respiratory Care Anatomy and Physiology: Foundations for Clinical Practice, 4th Edition details applied respiratory and cardiovascular physiology and how anatomy relates to physiological functions. Both trachea and bronchi are hollow organs which enabled the free flow of air. It is divided into three parts are nasopharynx, oropharynx, and laryngopharynx. This is present immediately after the nose. Head of PICU, King Fahad Medical City. We breathe in air rich in oxygen by the process called inspiration and breathe out air rich in CO2 by a process called expiration. The left lung is composed of two lobes which are smaller than the right lung. Supportive thoracic muscles and the diaphragm also play important roles in … The point where the trachea divides is known as the carina. So, the next part of the respiratory system anatomy and physiology is the trachea, the windpipe. The respiratory tract is the most common portal of entry and exit of microscopic disease agents. There are three mechanisms during external respiration: (1) ventilation which refers to gas exchange in the airways, (2) pulmonary perfusion, which speaks itself to the adequate perfusion of blood in the lungs, and (3) diffusion, which pertains to the movement of gas from an area of greater pressure to an area of lesser pressure through a semi-permeable membrane- it is through diffusion that internal respiration happens. 3. d) Moistening: When air travels over the mucous layer, the moisture present saturates the air with water vapor. PHYSIOLOGY OF RESPIRATORY SYSTEM 2. During exhalation, the muscles relax making the lungs contract. It is divided into three parts as nasopharynx, oropharynx, and also laryngopharynx. Respiratory System Quizzes. It is divided by the septum into two equal passages for air. The alveoli are made up of two types of cells called Type I and Type II cells. Respiratory System Anatomy – Major Zones & Divisions. The most commonly used anesthetics—the inhalation agents—depend on the lungs for uptake and elimination. The Anatomy and Physiology of the Respiratory System - Pleuresy = inflammation of the pleural lining Respiratory Physiology Pulmonary Ventilation = breathing Mechanism Movement of gases through a pressure gradient ... | PowerPoint PPT presentation | free to view Being the first passage of the respiratory system, the nose performs vital functions. There are two in number, with one on the left side and others on the right of the thorax or chest. Respiration can be considered into two, the internal respiration and the external respiration. Respiratory System- Anatomy and Physiology The respiratory system deals with ventilation and perfusion of tissues through the gas exchange process. Their walls have many passing tiny blood vessels. This movement of phlegm is helped by cilia on the surface of the tract. Due to the high blood supply to this layer, the air gets warmed. They move in one specific direction only. You have entered an incorrect email address! The most important side effects of both inhalation and intravenously administered anesthetics are primarily respiratory. These are important organs of the respiratory anatomy. 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. Title: The Anatomy and Physiology of the Respiratory System 1 The Anatomy and Physiology of the Respiratory System 2 Functions of the Respiratory System. The lower airways – trachea, bronchi, and the lungs are considered to be in the lower airways.
