A taste of the questions

Think it through

Scenarios, odd ones out and true or false and why, from IB Biology.

1. Capillaries in the kidney and the small intestine have tiny pores (fenestrations) in their walls. Why there?
2. Red blood cells squeeze through capillaries in single file. How does such a narrow vessel help exchange?
3. You can feel a pulse in your wrist artery but not in the veins on the back of your hand. Why?
4. Why does blood spurt from a cut artery but flow steadily from a cut vein?
5. I stretch every time your heart beats and spring back between beats, all along your arteries. What does my recoil do for your blood?
6. You count 18 beats at your wrist in 15 seconds. What is your heart rate?

Riddle me this

Course terms as riddles. Teams write what it is.

1. I'm only one cell thick, and so narrow that red cells pass through me in single file. What am I?
2. My walls are thick with muscle and elastic, I carry blood away from the heart, and you can feel me throb at your wrist. What am I?
3. I carry blood back to the heart at low pressure, with valves to stop it slipping backwards. What am I?
4. I'm the pull between water molecules that keeps a column unbroken all the way up a 100 m redwood. What am I?
5. I'm a woody polymer that stiffens xylem walls so they don't cave in under tension. What am I?

Quickfire

Short recall from the same topics.
