Answers
1. Diuretics help increase the production of urine and aid in micturition. There are three types: loop acting, potassium sparing, and thiazide diuretics.
2. Creatinine tests the ability of the kidneys to function and helps in estimating the GFR. It's formula is C4H7N3O
3. Einthoven's triangle is used in EKGs, it's the triangle formed by the left arm, right arm, and left leg

Are these the type of questions we are expected to answer in regionals?

Hey! From personal experience (I am in Division B), the level of difficulty in regionals depends based on the ES you have. Some tests are incredibly easy (the one I had this year had no written response nor diagram labeling!) while others may test you on complex concepts that requires a thorough understanding of the material. As for Andromeda215's questions, you should definitely know about Einthoven's triangle, which falls under ECGs, and creatinine. You should also know what a diuretic is, but I do not know if you need to know the specific types for a Division B regionals test. Again, there is room for fluctuation, but it would be in your best interest to study as much as possible!

And sometimes one should hope for a harder test! If you mess up on an easy exam, it is less likely that you will place as high because other teams probably also found the test easy (I placed 6th in regionals because I messed up on a few questions on an easy test). In other words, harder tests "filter" out the best from the rest and really show who knows the content. All in all, it won't hurt to know more, so study, study, and study! :D

Answers
1. The release of nitric oxide leads to vasodilation
2. interstitial fibroblasts?
3. Antithrombin is a glycoprotein that's function is to inactivate several enzymes in the blood clotting process, which in turn leads to the blood clotting response ending.
4. a. Urobilin

For 1, nitric oxide is broken down very fast because it is a very strong vasodilator and its effect needs to be controlled almost immediately.
For 3, antithrombin is a plasma alpha globulin that inactivates thrombin by binding to it, preventing blood coagulation
2 and 4 are good. Your turn
