The respiratory system helps in safe exchange of gases from outer atmosphere to inside the body. The respiratory zone allow inhaled oxygen to diffuse into the lung capillaries in exchange for carbon dioxide.

Anatomy Physiology Lecture Notes Respiratory System

Physiology of the respiratory system.

Anatomy and physiology of the respiratory system. Anatomy of the respiratory system. The respiratory is separated into the conducting zone and the respiratory zone. 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 conducting zone of the respiratory system includes the organs and structures not directly involved in gas exchange. There are multiple roles performed by the respiratory system. Pulmonary ventilation external respiration internal respiration transportation of gases and homeostatic control of respiration.

The organs of the respiratory system include the nose pharynx larynx trachea bronchi and their smaller branches and the lungs which contain the alveoli. Anatomy of the respiratory system nose and nasal cavity. 3 here is a brief description of each of those functions.

Cilia are found in the lungs respiratory tract and middle ear alveolar sacs alveoli alveoli are composed of epithelial layers and extracellular ma bronchiole the bronchioles or bronchioli are the passageways by which air lungs alveoli. The conducting zone include structures that facilitate air to move in and out of the lungs. The nose is the only externally visible part of the respiratory system.

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. Conducting zones nose to bronchioles form a path for conduction of the inhaled gases and respiratory zone alveolar duct to alveoli where the gas exchange takes place. Ventilation is the rate at which gas enters or leaves the lung.

Anatomy of respiratory system the respiratory system functionally can be separated in two zones. The physiology of respiratory system of human body is not a problematic one mostly but it is a delicate one and if neglected or hampered in early life it can reduce life span and quality of life drastically. Functional anatomy of the respiratory system the respiratory system include lungs airways and respiratory muscles.

The nose is a structure of the face made of cartilage bone muscle and skin that supports and protects the anterior portion of the nasal cavity. Functionally the respiratory system can be divided into a conducting zone and a respiratory zone. The respiratory system has a complex physiology and is responsible for multiple functions.

Millions of thin walle located outside of chest nose pharynx located in thorax trachea bronchi. Respiratory system anatomy major zones divisions. The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the bodys airwaythe respiratory tract through which air moves.
