Respiratory System

The picture link below shows a journey through the respiratory system

Notes are here and please get the diagram notes from me. Plus detailed notes here

Control of respiration

CO2 and H+ Levels

As monitored by the carotid and aortic bodies.  If these levels increase, they send a message to the  medulla oblongata Carotid bodies send the message through VAGUS NERVE.  Aortic bodies send the message through the GLOSSOPHARYNGEAL NERVE.  Medulla oblongata stimulates the rib cage and the diaphragm to move faster.

Acidosis:  pH < 7.35         too much carbon dioxide

Alkadosis: pHB> 7.45       not enough carbon dioxide (sometimes caused by hyperventilation)

The normal blood pH is tightly regulated between 7.35 and 7.45.

Carbon monoxide:   hemoglobin has a higher affinity for CO than for O₂ how would CO affect internal and external respiration?

What's on the test?

ON THE DAY OF THE TEST, HAND IN:
You must make a BIG ILLUSTRATED SUMMARY OF THE TOPICS WE COVERED.  THIS WILL BE OUT OF 10 MARKS.  IT MUST BE IN INK, IN COLOUR, AND INCLUDE ALL MAJOR VOCAB.

There will be a multiple choice test this friday May 3  based on the following.  Note that Fetal circulation will be excluded since it was not mentioned in class.

1.  your heart dissection.
2.  These notes which I gave out.
 the slideshowCirculation System
path of blood notes
  Major Blood Vessels
Do the review on blood vessels .
 and work on this guided study based on these summary notes

3.  Your notes on ECG:  these  fill in notes

And their answer key to look at

review your gigantic DIAGRAM on circulation

and we will explore the  path of blood . In particular, we will replicate William Harvey's experiment
