Anatomy Physiology VENTILATION Ventilation breathing. Moving air in out of lungs Oxygen pathway Air inhaled through nostrils nasal cavity pharynx larynx trachea mainstem bronchus conducting bronchioles terminal bronchioles respiratory bronchioles alveolar duct alveoli capillary body Carbon dioxide moves in reverse Airflow. 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.
Physiology of respiratory system Movement of inspired gas into and exhaled gas out of lung is called as ventilation. Understanding of lung volumes lung compliance ventilation-perfusion and bronchomotor tone are essential for clinical application of respiratory physiology in anaesthesia and critical care. Respiratory System Anatomy and Physiology Part 1 Now that we understood the basic function of the respiratory system we can start by looking into more detail of the anatomy and physiology.
Breathing in encourages our diaphragm to contract and pull itself down at the same time our chest muscles contract to open up the chest space allowing air to be sucked in like a vacuum. The anatomy of the lung maximizes the diffusion of gases. The respiratory membrane is highly permeable to gases.
The respiratory and blood capillary membranes are very thin. And there is a large surface area throughout the lungs. 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.
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 within the lung tissue. Respiratory System and the Skeleton. The skeletal system provides structure to soft tissue in the upper respiratory tract.
The perpendicular plate of the ethmoid the long section shown in blue separates the nasal cavity into sides. Anatomy and physiology of the respiratory system 1. ANATOMY AND PHYSIOLOGY OF THE RESPIRATORY SYSTEM DIPALI HARKHANI 2.
WHAT IS RESPIRATORY SYSTEM. The respiratory system also respiratory apparatus ventilatory system is a biological system consisting of specific organs and structures used for gas exchange in human. Organs of Respiratory System.
Respiratory Physiology Pulmonary Ventilation breathing Mechanism Movement of gases through a pressure gradient - hi to low. When atmospheric pressure 760 mmHg is greater than lung pressure —- air flows in inspiration. When lung pressure is greater than atmospheric pressure —- air flows out expiration.
ANATOMY AND PHYSIOLOGY OF THE RESPIRATORY SYSTEM The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe we inhale oxygen and exhale carbon dioxide.
Anatomy and Physiology of Respiratory System is a critical system. It supplies oxygen for energy and also excreates carbon-dioxide and other gases. The respiratory system is one of the 11 organ systems of the body.
Image from Human Anatomy Atlas. The trachea also known as the windpipe is the major airway of the lower respiratory system. It is a membrane made of cartilage that starts at the larynx and continues to the fifth thoracic vertebrae.
The trachea is about eleven centimeters long and 25 centimeters wide. This section describes the anatomy and physiology of the muscles involved in breathing. This includes not only the respiratory pump muscles but also the muscles in the upper airway that abduct the airway and the trunk musculature which is involved in maintenance of posture and stabilization of the pelvis and spine.
Anatomy Physiology of the Respiratory System - Chapter Summary. In this chapter our instructors outline the physiology and anatomy of the respiratory system. The nasopharynx of our respiratory anatomy is the space in the system that holds the uvula–the thing hanging from the roof of your mouth that you see when you say ah.
In the nasopharynx there is also the pharyngeal tonsil adenoids and the pharyngotympanic tube eustachian orifices that help to equalize pressure in the middle ear and throat. Functional Anatomy of the Respiratory System Nose The nose is the only external part of the respiratory system and is the part where the air passes through. During inhalation and exhalation air enters the nose by passing through the external nares or nostrils.
Nasal cavity is found inside the nose and is divided by a. Respiratory system - anatomy and physiology 1. Natomy of a ory system respirat pcu mary jo nelia b.

Inside the thoracic walls thoracic surface of the diaphragm and the lateral portion of the mediastinum. Space between the visceral and parietal contains pleural fluid which provides lubrication as lung expands and contact during respiration. Anatomy and Physiology of the Respiratory System.
The respiratory system is composed of the upper and lower respiratory tracts. The upper respiratory tract is composed of the nasal cavities pharynx and the larynx. The lower respiratory tract consists of the trachea bronchi bronchioles alveolar ducts and alveoli.
