The three mechanisms which regulate the heart are endocrine, cardiovascular and Sinoatrial nodes.
The endocrine system consists of the glands and hormones of the human body. The cardiovascular system is the organ system which is responsible for the circulation of the blood around the body and the oxygenation of the body's tissues. The sinoatrial node (SA node) generates the electrical impulses and is considered the natural pacemaker of the heart.

Predators possess usually good senses to find their prey and special abilities to trap the prey. Predatory birds, for example, had an outstanding eyesight and sometimes hearing, for the case of the owls while other predators, like many species of mammals, have a very high sense of smell that helps them locate prey. Many predators are very fast, and use their speed to help capture their prey, some are fastest runners, fast fliers and fast swimmers.
