Here are the slides for your worksheet
And here's your worksheet

 Male system and fertilization 
Development and birth 

Questions - you will be given blank sheets of paper. Create a booklet with table of contents and answer these questions on Wednesday.

For Wednesday
Each question is worth 5 marks. These questions are NOT open book

1.  When air is drawn into the lung
a.  What happens to the ribs and diaphragm and how does this effect the overall volume of the thoracic cavity?
b   What is the function of the pleural membranes?


2.  What are the two chemoreceptors which regulate breathing  and tell your diaphragm to contract? Using a drawing, explain how the chemoreceptors work to increase breathing rate.

3.  Write about a lung disease of your choice

4.  Using drawings, to illustrate your answer, write the equation for the carbonic acid buffer below and state which way equilibrium moves and also how hemoglobin picks up and drops off oxygen, carbon dioxide and Hydrogen ion in the following locations:
a.  at the tissue
b.  in the blood
c.  in the lung


5. What are the three forms of hemoglobin?

6. What environmental conditions cause carbaminohemoglobin and reduced hemoglobin to drop their load of carbon dioxide and H+ ions and pick up oxygen?

7.  Draw a graph illustrating
a. how pH affects oxygen binding to hemoglobin
b. how temp affects oxygen binding to hemoglobin

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)

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

Fetal Circulation

Today we explored fetal circulation.  First we drew our conception of how fetal circulation might occur. Next we compared fetal and baby circulation in depth in the table below.  Finally we drew a schematic diagram to compare the two and listened to a baby cry because the newborn's first breath is when the ductus arterioles and the foramen ovale closes successfully
