describe how the position of the normal lungs relate to the surfsce
anatomy of the anterior, lateral and posterior thorax.

describe the structure of the pulomonary capilleries and show how they
were adapted to contribute to a large thin membrane for gas exchange.

What are the functions of tehj elastic fibres found in the lungs?

The position of the lungs.
This site gives a description of the position of the lungs and is
illustrated with diagrams showing anterior, lateral and posterior
views. A chart gives the surface markings in relation to the ribs.

and how to mark out the anterior and posterior borders.

The pulmonary capillaries.
The capillaries are arranged in a fine network or ?cobweb? which cover
the surface of the alveoli. The capillary walls are in direct contact
with the epithelial lining of the alveoli. This fine, thin network
provides a large surface area for the exchange of gases.

This site gives a detailed description description of the alveolar
capillary interface.
?The capillary endothelium is metabolically active. It converts
angiotensin I to anfiotensin II, produces factor 8 and inactivates
prostaglandins E2 and F2a, lekotrienes, and serotonin. The pulmonary
capillary endothelium is the principal site of liquid and solute
filtraton with a net outward flow of 10-20ml/hr in adults. This fluid
is removed via the pulmonary lymphatics.? (Source:  Structure of the
Airways, Parenchyma and Blood Vessels by Jonathan D. Finder, M.D).

Elastic fibres
The elastic fibres hold the bronchial open. The elastic fibres exert
tension on the bronchial walls, by pulling in all directions they help
maintain the patency of the bronchioles.

Thank you so much for your help.  I was begging to get very
dishartened as I seemed unable to find teh corrrect search words.


Thank you again.
