atrioventricular valves – one particular-way valves located involving the atria and ventricles; the valve on the ideal is called the tricuspid valve, and the a single to the remaining is the mitral or bicuspid valve.
capsaicin – molecule that activates nociceptors by interacting by using a temperature-delicate ion channel which is The idea for “warm” sensations in spicy food.
coronary arteries – branches from the ascending aorta that offer blood to your heart; the left coronary artery feeds the left aspect of the heart, the left atrium and ventricle, along with the interventricular septum; the proper coronary artery feeds the proper atrium, portions of the two ventricles, as well as the heart conduction program.
