Anatomy 1.2 - Basic Physiological Processes

These are tiny particles of matter

• cells

• atoms

• organs

• tissues

The smallest building blocks of all living beings are called

• atoms

• cells

• tissues

• organs

This place receives and analyzes information from sensory receptors, then sends a command stimulus to an effector to maintain homeostasis.

• effector

• receptor

• control center

The unit that receives a command stimulus from the control center and causes an action to help maintain homeostasis is called this.

• effector

• receptor

• control center

Which of the following descriptions defines homeostasis? 

• Maintaining a stable internal environment

• The sum of all the body’s reactions

• The goal of positive feedback mechanisms

• Creating energy in the form of ATP

A condition in which there is a decreases ability for an organ system to maintain the body's internal environment within normal ranges (homeostasis)

• metabolic rate

• homeostatic imbalance

• positive feedback

• organ systems

Organ systems cooperate to maintain homeostasis through a process called

• homeostatic mechanisms

• metabolic rate

• positive feedback

• effector

The speed at which the body consumes energy is called the -

• homeostasis

• positive feedback

• metabolic rate

• receptors

This relates to all chemical reactions that occur within an organism to maintain life.

• metabolism

• homeostasis

• negative ffedback

• positive feedback

Atoms combine together in different ways to form larger particles known as -

• Cells

• Molecules

• Tissues

• Organs
