Ans. Contractility. It is defined as the intrinsic ability of the heart muscle to contract. An Anrep effect happens when there is an increase in contractility due to the activation of catecholamines. When this happens, it allows myocardium to compensate for an increase end-systolic volume and decreased stroke volume that occurs when aortic blood pressure increases.

The percentage of blood loss causes a urine output of at least 20 ml/hour in a 70 kg patient is about 15% to 30%.
<h3>What is urine output?</h3>
Urine output is the method use to the total amount of fluid present in the body once the nutritive part have been absorbed by intravascular cells.

Answer: the study of the behavior that manifests itself and the focus on the importance of unobservable mental processes.
Explanation:
The founder and top precursor of behaviorism was John B. Watson, who founded the Behavioral Psychological School. He sought with his behavioral theory to study the behavior and from this process explain how learning occurs. Watson saw psychology as a process of prediction and behavior control. Behaviorism is therefore based on science since it can be measurable, observable and quantifiable.
In his theory, Watson highlights what Stimulus-Response is. The stimulus can be defined as an object whose purpose is to trigger behavior or reaction, while the response is the result or reaction that is obtained after exposure to the object. While it is true that certain responses to stimuli are expected, this does not mean that the desired ones will always be obtained, but in turn, this theory tests the reactions that occur to exposures to certain stimuli.
One of the most famous examples in behaviorism is the experiment of salivation with the dog, conducted by Ivan Pavlov. This experiment gives rise to what classical conditioning is and forms a fundamental part of the sources that place behaviorism as objective science. Watson and Pavlov, within their behavioral theories, sought to go beyond introspective processes, seeking to understand behavior by measuring it through observable behaviors and events.
When an answer occurs, it is not due to just one stimulus, but there may be several. Behaviorism does not reject that there may be background stimuli at the time the present stimulus causes a certain reaction, but its focus is on environmental events.
