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. Accurate knowledge of anatomy and physiology of the respiratory tract is important not only in the field of pulmonology but also in anaesthesiology and critical care.

About 7080 of the morbidity and mortality occurring in the perioperative period is associated with some form of respiratory dysfunction1. The muscular and nervous systems enable the involuntary breathing mechanism. The main muscles in inhalation and exhalation are the diaphragm and the intercostals shown in blue as well as other muscles.

Exhalation is a passive action as the lungs recoil and shrink when the muscles relax. Image from Human Anatomy Atlas. 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. 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 and physiology of the respiratory system 1.

Included in the upper respiratory tract are the Nostrils Nasal Cavities Pharynx Epiglottis and the Larynx. The lower respiratory tract consists of the Trachea Bronchi Bronchioles and the Lungs. As air moves along the respiratory tract it is warmed moistened and filtered.

The lungs flank the heart and great vessels in the chest cavity. 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.

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.

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 3rd edn. Mosby St Louis 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. 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 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. The Respiratory System Continued The respiratory system is a continuous series of passages that begins with the nose and ends in the alveoli of the lungs. The upper respiratory system includes the nose pharynx larynx and the trachea.

The lower respiratory system includes the right and left bronchi their subdivisions and the lungs. Respiratory system anatomy and physiology Videos Flashcards High Yield Notes Practice Questions. Learn and reinforce your understanding of Respiratory system anatomy and physiology.

Anatomy Physiology 59 Introduction to the Respiratory System The major function of the respiratory system is to obtain oxygen and remove carbon dioxide for metabolic processes in the body. Breathing is the physiological process that moves air in and out of the lungs in terrestrial vertebrates. Respiration is often referred to as breathing but it can also mean cellular respiration which is the main reason why breathing is important.
