Keeping chickens safe from predators has to be top on your list of priorities. There are several animals around the World that will prey on chickens and itâs your job to keep them safe and not letting them become part of the local wildlifeâs food chain!
The right coronary artery gives rise to acute marginal branches and terminates as the posterior descending artery in at least 80% of the population, supplying septal perforator arteries to the posterior intraventricular septum.
In about 50% of humans a third coronary artery (conus artery) arises from a separate ostium in the right sinus. The left main (LM) coronary artery ranges in length from 1 to 25 mm before bifurcating into the left anterior descending (LAD) and left circumflex (LC) branches. The LAD coronary artery measures from 10 to 13 cm in length, whereas the usual nondominant LC artery measures about 6 to 8 cm in length. The dominant right coronary artery (RCA) is about 12 to 14 cm in length, before giving rise to the posterior descending artery(PDA).
