If cockroaches are seen in other areas such as bedrooms or utility rooms, use 2-4 additional baits. Do not spray around bait stations with other insecticides or cleaning agents as this could deter roaches from feeding on the bait. Substantial reductions in cockroach numbers should occur within 1-3 weeks of treatment.
The left main coronary artery (LMCA) arises from the left aortic sinus, running towards the left hand side of the heart, just below the left auricle. It quickly divides into the anterior interventricular branch also known as the left anterior descending (LAD) artery and the circumflex artery.The LAD runs along the anterior interventricular sulcus, a groove in the anterior surface of the heart that seperates the left and right ventricle, down towards the apex.rom here, it curls around towards the inferior surface of the heart, forming the posterior interventricular branch, more commonly known as the posterior descending artery (PDA). The PDA runs along the posterior interventiculas sulcus, to supply blood to the walls of both the left and right ventricle.
Branches of the Aorta. 1  Ascending Aorta - initial part of the aorta that begins from the aortic valve and extends from the left ventricle of the heart to the aortic arch. Coronary Arteries - arteries branching from the ascending aorta to supply oxygenated blood to the heart wall.
