Easy:
The four chambers of the heart are the right and left atria, and the right and left ventricles. The main veins connected the heart are the superior and inferior vena cava, the main artery is the Aorta.
The first chamber, (the right atruim) recieves deoxygenated blood and forces it into the right ventricles which forces the blood into the lungs for oxygenation. Then the blood reenters the heart in the left atrium, which forces the blood into the left ventricle and then out the Aorta to the rest of the body.

Answer:
Affected animals given a galactokinase inhibitor do not experience toxicity.
Explanation:
Galactokinase: Catalyzes is the first and committed step of the Leloir pathway involving the conversion of galactose to glucose. It causes phosphorylation of α-D-galactose to galactose 1‑phosphate. Thus, inhibiting galactokinase wil greatly decrease the levels of galactose 1‑phosphate.
