Unit 3E

Respiratory System

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
The left lung has how many fissures ? 1
Fissure(s) of the left lung ? Oblique Fissure
The Fissure of the right lung Subdivides the the LEFT lung into how many lobes ? 2
what are the 2 lobes of the left lung ? Upper (superior) lobe, Lower(inferior) lobe
