Introduction to Anatomy and Physiology Slides 1-12

Front

What is Anatomy?

Back

Anatomy is the branch of biology that studies the structure of organisms and their parts.

Front

What is Physiology?

Back

Physiology is the study of how the body and its parts work or function.

Front

What is Homeostasis?

Back

Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions.

Front

What is Negative Feedback?

Back

Negative feedback is a mechanism that counteracts a change in a physiological variable, helping to restore balance.

Front

What is Positive Feedback?

Back

Positive feedback is a mechanism that amplifies a change in a physiological variable, moving the system away from its starting state.

Front

Give an example of Positive Feedback in the body.

Back

Childbirth is an example of positive feedback, where the release of oxytocin increases contractions during labor.

Front

How does Negative Feedback help regulate body temperature?

Back

Negative feedback helps regulate body temperature by activating effectors like sweat glands to cool the body when temperature rises.

Front

What role does the Sensor play in a Negative Feedback loop?

Back

The sensor detects changes in the environment and sends information to the control center.

Front

What is the Control Center in a Negative Feedback loop?

Back

The control center processes the information received from the sensor and determines the appropriate response.

Front

What are Effectors in a Negative Feedback loop?

Back

Effectors are organs or cells that carry out the response to restore balance in the body.
