Question Answer
What is the flow of air through the respiratory system?larynx, trachea, lung, alveoli, heart, bronchus, heart, bronchiole, intercostal muscle, diaphragm and ribs

Section 2

Question Answer
8.intercostal muscle
what is the tree calledbronchuss
what are the branches calledbronchioles

Section 3

Question Answer
What are the segments of the bronchi?primary, secondary (lober), and tertiary (segmental)
what is the difference in structure between the trachea and the bronchi?the c-rings become plates, and the epithelium changes to simple columnar and to cuboidal in the smallest bronchi
structure of bronchiolesless that 1mm thick
alveolar ductstheir walls are almost entirely filled with alveolar sacs
alveoliwhere gas exchange occurs
what is type I alveolar cellmade of simple squamous tissue and is attached to a basement membrane
what is type II alveolar cellsecretes a surfactant the produces surface tension within the alveoli
what is type III alveolar cellalveolar macrophage
what are the 3 types of alveolar cellsType I, II,and III

Section 4

Question Answer
What is the path of oxygen in the respiratory membrane?type I cell--> alveolar basement membrane--> basement membrane of the capillaries--> tunica interna
what is the general structure of the lungs?apex, base, cardiac notch, hilum, root
what is the apex of the lung?superior, narrow portion
what is the base of the lung?concave, inferior portion
what is the cardiac notch of the lung?located on the left lung to accomodate for the heart
what is the hilum of the lung?place where blood vessels, lymphatic vessels, bronchi, and nerves can pass through
what is the root of the lung?attaches the lungs to the mediastinum
what is the structure of the left lung?superior lobe, oblique fissure, and inferior lobe
what is the structure of the right lung?superior lobe, horizontal fissure, middle lobe, oblique fissure, and inferior lobe
what is the pleurae membrane consist of?parietal layer, visceral layer, and the pleural cavity
where is the location of the parietal layer?covers body wall surrounding the lungs
where is the visceral layer? covers the external surface of the lungs
what is the pleural cavity?space between the pleurae; filled with think film of pleural fluid
