operant conditioning

Explanation:

Operant conditioning, also called instrumental conditioning, is a learning method that makes use of the association of reinforcements (rewards) and punishments with a particular behavior or pattern of behavior. Through operant conditioning, an association is made between a behavior and a consequence of that behavior. This method is widely used in animal training.

Operant conditioning is based on a simple premise: actions followed by reinforcement will tend to repeat themselves. On the other hand, actions that result in unintended punishments or consequences will weaken and are less likely to occur again in the future.

An example: When a lab rat presses a blue button, he receives a food ball as a reward, but when he presses the red button, he receives a slight electric shock. As a result, he learns to press the blue button but avoids the red button.

what bodys are there orbiting?

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
