Q

What are the four types of tissue?

A

Connective tissue - supports and protects body organs.

Epithelial tissue - coverings and linings (skin).

Muscle tissue - cardiac, skeletal and smooth. Provides movement and protects organs.

Nervous tissue - nervous system, rapid internal communication. Not just neurons.

Q

Metabolism is?

A

Metabolism refers to all chemical reactions in the body.
There are two types

Catabolic (break down complex molecules to simple ones)

Anabolic (combine molecules to form complex molecules) reactions.

Q

What are the three interdependent components for homeostatic control mechanisms?

A

Receptor - sensing component that monitors and responds to changes in the environment. When it senses a stimulus, it sends information to a control centre.

Control system - Control centre is the component that sets the range at which a variable is maintained and determines an appropriate response. e.g.

Effector - the receptor stimulated then responds by either enhancing the stimulus with positive feedback or depressing it with negative feedback.
