BIOS255 Ch 23 The respiratory system guaranteed pass A+ grade

Define Respiration Respiration is the exchange of gases between the atmosphere, blood, and cells The combination of 3 processes is required for respiration to occur Ventilation (breathing) External (pulmonary) respiration Internal (tissue) respiration Brainpower How does the cardiovascular system assist the respiratory system? By transporting gases Structures of the Respiratory System Structurally, the components of the respiratory system are divided into 2 parts: 1. Upper respiratory system 2. Lower respiratory system Functions of the Respiratory System Functionally, the components of the respiratory system are divided into 2 zones: 1. Conducting zone 2. Respiratory zone Upper Respiratory System consists of: The nose, pharynx (throat), and associated parts Lower Respiratory System consists of: The larynx, trachea, bronchi, and lungs Hyaline cartilage Hyaline cartilage is found throughout the respiratory tract in order to keep the moist airway open Equation for measuring the amount of air that moves in and out of the lungs each minute (Minute Ventilation) The product of tidal volume and breathing rate indicates the amount of air that moves into and out of the lungs each minute (minute ventilation, MV = TV × BR).
