Anatomy And Physiology Of Respiratory System

The nose is the only externally visible part of the respiratory system. Anatomy of the respiratory system.

Anatomy Physiology Lecture Notes Respiratory System

Anatomy of respiratory system the respiratory system functionally can be separated in two zones.

Anatomy and physiology of respiratory system. Ventilation is the rate at which gas enters or leaves the lung. Respiratory system anatomy major zones divisions. The conducting zone include structures that facilitate air to move in and out of the lungs.

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. Such structures include the nasal cavity pharynx larynx trachea and most of the bronchial tree. 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.

The respiratory zone allow inhaled oxygen to diffuse into the lung capillaries in exchange for carbon dioxide. The organs of the respiratory system include the nose pharynx larynx trachea bronchi and their smaller branches and the lungs which contain the alveoli. There are multiple roles performed by the respiratory system.

Pulmonary ventilation external respiration internal respiration transportation of gases and homeostatic control of respiration. 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. The respiratory zone includes all the organs and structures that are directly involved in gas exchange including the respiratory bronchioles alveolar ducts and alveoli.

The respiratory system helps in safe exchange of gases from outer atmosphere to inside the body. 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. The respiratory is separated into the conducting zone and the respiratory zone.

Functional anatomy of the respiratory system the respiratory system include lungs airways and respiratory muscles. Physiology of the respiratory system the respiratory system has a complex physiology and is responsible for multiple functions.
