aorta - 2026 ACF Regionals

Question

Due to ventricular septal defects, this artery is described as overriding the right ventricle in one abnormality that characterizes Tetralogy of Fallot. For 10 points each:

[10e] Name this largest artery that normally carries oxygenated blood away from the left ventricle and into general circulation.

ANSWER: aorta [accept ascending or descending or transverse aorta; accept thoracic aorta; accept transverse aortic arch]

[10h] Improper development of the cardiac subset of these cells can result in Tetralogy of Fallot for patients with DiGeorge syndrome. Somites guide the migration of these cells, a group of which differentiate into melanocytes.

ANSWER: neural crest cells [accept cardiac neural crest cells; prompt on cranial cells or trunk cells; prompt on stem cells or multipotent cells]

[10m] Children born from mothers with high values for this quantity have an elevated risk of developing congenital heart diseases. The hemoglobin A1c (“A-one-C”) test is used to estimate the three-month average of this quantity.

ANSWER: blood sugar levels [accept serum sugar levels; accept blood glucose levels or serum glucose levels; accept glycemia; prompt on glucose levels or sugar levels by asking “in what substance?”]
