In canine heartworm disease, adult worms are found primarily in which heart chamber?

Explanation:
Right ventricle. In heartworm disease, adult worms dwell on the right side of the heart, mainly in the right ventricle and the adjacent pulmonary arteries. Blood flows from the right atrium into the right ventricle and onward to the lungs, so the worms settle where the venous blood concentrates and where the pulmonary circulation provides their preferred environment. The left-sided chambers deal with oxygenated blood returning from the lungs and are not typical habitats for adult heartworms.
