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.

Also, what are the forces that act on the capillaries in Starling's forces again?
Starlings forces is talking about hydrostatic and oncotic pressures in the capillaries/interstitial fluid. The four forces are hydrostatic capillary pressure, oncotic capillary pressure, hydrostatic interstitial, and oncotic interstitial. (Oncotic = colloid osmotic) Hydrostatic is the pressure from the fluid (in this case water) while oncotic is pressure created by proteins in the blood plasma. Greater hydrostatic pressure in the capillaries leads to filtration, while water will move into the capillaries if oncotic pressure is higher, because water potential is lower.

Also to note, Starling’s Law and Starlings Forces are two different things, so if it ever asks about Starling’s Law, it refers to stroke volume and end diastolic pressure in the heart (more in; more out).

Ok, so the general equation for starling's forces is just (all forms of hydrostatic pressure) - (all forms of oncotic pressure)?

Are medals achievable even if your partner is doing nothing? For ex, I am doing 2 systems and my partner is doing 1. He is not working very hard, and not giving A+P too much time.

I tried doing his studies too but it too hard at the last moment, so I am really questioning my chances of winning a medal?

My friend managed to get 1st with a kinda bad partner, so it's definitely possible. You just have to be really passionate and study as much as possible.
Nothing for now...
Keep on going :!:

Hi, I was having a hard time finding a diagram for thymus which would be appropriate for the competition. So could someone pls help?
