Circulating... Circulation...So Bloody...!

Hello! HBL.. what is that? Home. Based. Learning!
So in essence, it means that
1) You do this at HOME!
2) You LEARN!

Ok, no DIM DIM, no Bright Bright, no Dark Dark for MISS CHUA's Biology.
So it's just the good old boring misschuabiology.blogspot.com! :)

So what?

1) You may read through my Circulation slides. (Which i will still run through the contents next week when i see you all in person!)
2) See the heart dissection slides. Warning! Not for the faint hearted! :P
3) Attempt the question below. Answer in your Biology notebook. We will go thru in class next week! :)

Question:

If you could re-design the single circulatory system of a fish by re-locating the various blood vessels, would you place the pulmonary arteries and veins before the heart or after it? (In other words, would the blood enter the gills before it enters the heart, or vice versa?)

Explain your choice with reference to how the rate of exchange (between blood and the body’s tissues) and the rate of transport (of blood to various parts of the body) would be affected.
