Term | Definition |
the system of the body concerned with gas transport and exchange | Respiratory system |
2 phases of the respiratory system | 1. Conductive Phase 2. Gas Exchange Phase |
phase concerned with the movement of gases from the outer enviroment through the respiratory tubes to the lungs. | Conductive phase |
phase concerned with the exchange of O2 and CO2 between the blood and the air sacs of the lungs | Gas Exchange Phase |
The 6 organs of the respiratory system | 1. Nasal Cavity (oral cavity) 2. Pharynx 3. Larynx 4. Trachea 5. Bronchi 6. Lungs |
referred to as the nose and the mouth | Nasal Cavity ( oral cavity) |
Muscular tube for passageway of air and food | Pharynx |
Cartilage tube for passageway of air, contains vocal cords | Larynx |
The Trachea is a______ and_______ tube extending from the larynx above, to the point at which it bifurcates into 2 primary bronchi below | cartilaginous, membranous |
The Trachea is called the _____ by lay people | Windpipe |
The Trachea is about __ cm in length in vivo. | 15 cm |
The Trachea is composed of __ - __ C-shaped rings of _____ cartilage , so that each almost encircles the lumen | 16-20, Hyaline |
in the trachea the OPEN ends of the incomplete cartilaginous rings are directed ______, and the gap between the 2 ends of each ring is bridged by _____ tissue and _____ muscle. | Posteriorly, Connective , Smooth |
in the trachea The connective tissue bridge between the 2 ends of each ring is adjacent to the posteriorly related ______ | esophagus |
The Tracheal ______ marks the end of the trachea and the beginning of 2 primary _____ | Bifurcation , Bronchi |
it is the _____ bronchi that that will enter the substance of the lungs | primary |
The trachea lies _____ to the esophagus | anterior |
The trachea terminates by bifurcating on to 2 primary bronchi called the ? | Right Primary Bronchus, Left Primary Bronchus |
Which bronchus is wider, shorter , and straighter ( forms less acute angle with the trachea) ? | RPB |
The RPB is approx ___ cm in length | 2.5 cm |
The RPB enters the right lung at the _____ of the right lung and divides into 3 _______ Bronchi , 1 for each of the lobes of the right lung | Hilus, Secondary |
Each of the 3 secondary bronchi will branch again into ______ bronchi what will supply a _____________ segment | tertiary . BRONCHOPULMONARY |
The Term BRONCHOPULMONARY segment is applied to the _______ segment within a lobe of the lung. | Largest |
BRONCHOPULMONARY segments are separated from each other by ______- tissue septa that prevent ______ of air from 1 segment to another | connective, diffusion |
The Left Primary Bronchus is ______ in caliber but about ___ as long as the right (__cm) | Smaller, twice , 5 cm |
The LPB makes ___ of an acute angle then the RPB | more |
so if u are choking because something falls from the though the trachea most likely something is lodged in the _____ since its more inline with the trachea. | RPB |
The LPB enters the left lung through the _____ and divides into 2 secondary bronchi , 1 for the upper lobe and 1 for the lower lobe | Hilus |
In the LPB the tertiary bronchi subdivide_____ times and eventually into many _______. | numerous, Bronchiols |
Bronchioles are much ______ and more ______ then bronchi. | smaller, numerous |
Bronchioles do not contain _____ in their walls to prevent them from ______ on inspiratory movements because they are _____ the substance of the ____ which itself is expanded during inspiratory movements. Compared to bronchi | cartilage, collapsing, inside, lungs |
The terminal bronchioles in turn divide into ________ bronchioles | Respiratory |
Respiratory bronchioles are very ____ tubes composed of ______ tissue and ______ muscle. | small,connective, smooth |
A few ____ bud off the respiratory bronchioles and are the reason why these bronchioles are termed respiratory bronchioles | alveoli |
The respiratory bronchioles ___ and ___ conelike into _ to _ alveolar ducts. | Branch, Radiate, 2,11 |
The ____ ducts are long thin-walled tubes of _____ tissue and ___ muscle | Alveolar, connective, smooth |
From the alveolar ducts arise ___ alveoli and alveolar ___ containing __ or more alveoli. | single, sacs, 2 |
At the level of alveoli there is NO longer any _____ or _____ ____ . | cartilage, smooth muscle |
All that remains of alveolar walls is a ___ layer of ____ and _____ tissue | thin, epithelium, connective tissue |
the most conspicuous feature of the alveoli is the presence of numerous _____ adjacent to them | Capillaries |
The capillaries are situated so that a great portion of their surface is directed towards the ___ . since it is the alveolar wall plus the capillary wall that make up the respiratory membrane, which is the membrane which ___ exchange will occur. | alveolus(small cavity) , gas |
There are _ lungs in the body , properly called the ? | Right lung, Left Lung |
Each lung presents an ____, ____, & _ surfaces | Apex, Base, 3 |
the round superior end of the lung is called the ? | Apex |
The 3 surfaces of the lungs are ? | Costal Surface, Diaphragmatic Surface ( base), Medial Surface |
The surface adjacent to the thoracic wall | Costal Surface |
The thoracic wall consists of 4 things what are they ? | sternum, ribs, costal cartilage's, intercostal muscles |
That part of the lung adjacent to the upper surface of the diaphragm. and what is it also called ? | Diaphragmatic Surface , (base) |
Since the Diaphragm projects ____ forming _#_ domes, the Diaphragmatic Surface is ______. | upward,2, concave |
The part of the lung adjacent to the heart and other thoracic organs | Medial Surface |
The medial surface presents a ____, the ____ or _____, where all the structures that will enter or leave the lung will pass. | locus, Hilus, Hilum |
The name that is given to collectively to all of the structures that enter or leave the lung at the hilus is the _____ of the lung | Root |
The 3 structures forming the ROOT are ? | Pulmonary Artery, Pulmonary Veins , Primary Bronchus |
a branch of the pulmonary trunk that will bring deoxygenated blood from the heart to the lung | Pulmonary artery |
This structure will carry oxygenated blood from the lung back to the heart. | Pulmonary Veins |
How many pulmonary veins are there total and how many per lung. | 4, 2 per lung |
The branch of the trachea , that serves as a passage way for air | Primary bronchus |
The right lung has how many fissures ? | 2 |
Fissure(s) of the right lung ? | Oblique fissure, Transverse fissure |
The fissures subdivide the RIGHT LUNG into how many lobes ? | 3 |
what are the 3 lobes of the right lung ? | Upper (superior) lobe, Middle lobe, Lower (inferior) Lobe |
