WEEK 7

RESPIRATORY ANATOMY & HISTOLOGY

Exercise #45 & 46

LAB 45 (pages 355-362) & LAB 46 (page 369) + tissue drawings

Write in full sentences where more than one word is indicated and label all listed structures on the drawings. REQUIREMENT: USE COLORED PENCIL FOR THE DRAWINGS—POINTS WILL BE TAKEN FOR DRAWINGS THAT DO NOT HAVE THE STRUCTURES LABELED. Look at the full size models in the classroom and the diagrams in the lab & textbook. There are photos of tissue in Exercise 45 and the histology cards for support. However, histology drawings must be from images the student sees under the microscope. This material will appear on the practical so you will want to view all of the slides and know the location of all of the respiratory structures. You may also want to write little descriptions of the structures so that you can identify them later. (The lab is open on Fridays for those of you who do not complete the assignment). Familiarize yourself with the location, function, and general macroscopic and microscopic structure of the:

CONDUCTING ZONE

RESPIRATORY ZONE

LUNG

BLOOD VESSELS

nose:

nasal cavity

nasal septum

nares

larynx:

vocal folds

thyroid cartilage

cricoid cartilage

glottis

epiglottis

laryngeal prominence (Adam’s apple)

respiratory bronchioles

pulmonary hilus

pulmonary trunk

alveolar ducts

visceral pleura (pulmonary pleura)

left and right pulmonary arteries

alveolar sacs

left lung

superior lobe

inferior lobe

oblique fissure

cardiac notch

pulmonary veins

pharynx:

nasopharynx

oropharynx

laryngopharynx

alveoli

type 1

type 2 cells

trachea

Bronchi

primary bronchi

secondary bronchi

bronchioles

respiratory membranes

right lung

superior lobe

middle lobe

inferior lobe

oblique fissure

horizontal fissure

Structures in each drawing must be labeled in order to receive full credit. I will take points for slides that do not have the following labels. (The structures that must be labeled are listed in the boxes)

lung

trachea

alveoli

type I cells

mucosa

submucosa

hyaline cartilage ring

lumen

Know the difference between pulmonary, cardiac, and systemic circulation
