What were the scores for MIT invitational for anatomy? I can't find it on the website.
They dont release everyone's scores, only the highest ones. The highest for anatomy was a 155.

Oh yeah, what type of connective tissue is the thymus and how is different from other lymphoid organs? I can't find the answer online.

From what I remember, the other lymphatic organs (spleen, tonsils, lymph nodes, etc.) have reticular connective tissue but the thymus doesn’t. The thymus has dense connective tissue.

What were the highest scores for anatomy B and C of the University of Austin Invitational?

Can you guys explain these problems?

25. (1) Which of the following is not a way that lymph
flow is produced?
A. Skeletal muscles squeezing lymphatic vessels
B. Arterial pulsation
C. Venous pulsation
D. Thoracic (respiratory) pump
E. Varying pressures within the thoracic and
abdominal cavity

I put B, but the answer was C. I thought that because the lymph drains into the superior vena cava, the vein pressure does do some work?

30. ** (1) Which of the following is untrue regarding the
spleen?
A. It is located in the left hypochondria region
B. It is protected by ribs 7-9
C. It is ventromedial to the stomach
D. It is inferior to the diaphragm
E. A & B
F. A & C
G. A & D lol
H. B & C
I. B & D
J. C & D

The answer was H, but I put C. Isn't there some rule called the 1*3*5*7*9 mnemonic where the spleen is protected by ribs from 7-9?

...
25) First, lymph drains into the left and right subclavian veins, not straight into SVC, and the location of where lymph drains does not affect the flow of lymph at all. Arterial pulsation affects lymph flow because arteries have stronger pulses while venous pulsation is not as noticeable and not nearly as strong.

30) The mnemonic is 1 3 5 7 9 11, where it means the dimensions of the spleen are 1 x 3 x 5, it weighs 7 ounces, and are protected by ribs 9 and 11.

thymus connective tissue includes reticular cells, which functions as antigen presenting cells (APC) and unlike reticular cells in other oragans, are involved in "T cell training" (making sure T cells recognize self from non self and not attack our own cells)

most deep lymphatics travel close to arteries (sometimes in a connective tissue sac with arteries) and arterial pulsation plays a role in the lymph flow. veins do not pulsate as the pressure is steady and does not change with systole and diastole, and venous pressure is not a major factor
