Quick question... In the question below I feel the answer is c, but the answer key states that the answer is b, so can somebody pls advise me on what I did wrong. My reasoning behind my answer was that veins collect the "bad stuff" (CO2 and waster material). Sorry I couldn't get the diagram in here:(

Q) In this blood flow diagram for the legs and pelvic area, which exchange vessels lose oxygen to body tissues and receive carbon dioxide and waste materials from the tissues?

a) Post-capillary arterioles and arteries.
b) Capillaries and post-capillary arterioles.
c) Capillaries and post-capillary venules.
d) Post-capillary venules and veins.

There are no such thing as POST capillary arterioles, after capillaries, its all venous system. so c is the correct answer. Just capillaries would be the best answer as capillary is the only "exchange membrane"

Thank You, this was my thinking too, but your explanation helped me double check my thinking. This test was an invitational's test which I get from Scioly test exchange page, I think the ES at the invitational made a mistake.

Yes, you wouldn't need to time anything for BP.
Wouldn't doing a blood pressure measurement be biased? Because depending on the person their blood pressure could fluctuate at any moment based on what they're doing?
Well, the person would just be sitting in a chair or something where he is stationary, so his BP would be pretty constant. However, I do see what you mean. Maybe they just want to see if you can do it so you have practical knowledge.

I encountered one more question which I couldn't understand the answer for, so any help would be highly appreciated!

How many known human blood group systems are there?

a.3
b. 12
c. 14
d. 35

THE ANSWER KEY SAID THE ANSWER WAS D. I DON'T UNDERSTAND HOW THEY GOT D, SO CAN SOMEONE HELP ME UNDERSTAND, YOUR HELP WOULD BE GREATLY APPRECIATED!

I'm guessing your answer was A? It's not A because A is trying to confuse you with the A, B, and O found in the ABO blood type system. The ABO blood type system is only one of the 35 major blood grouping systems out there, with ABO being the most common.

What are the blood groups and do we honestly have to know them?

Also, what are the forces that act on the capillaries in Starling's forces again?

Thank You, I honestly didn't have an answer to this question, and your explanation really helped. :)

I’ve heard of there being 35 different types of systems before, but only actually encountered 2, 1 of them being the ABO blood typing system. The other one is Rh, which is generally associated with ABO and is sometimes indicated by letter D, C, c, E (different antigens) or just straight up “Rh” (Rh: rhesus). Rh(D) is the system that indicates a “positive” or “negative” blood type (ie AB positive) and I haven’t encountered too many questions about it. It’s just important to know that Rh is dominant for the positive trait and Rh negative means an individual lacks the Rh antigen.
