What is 98.6°F?

200

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

What is physiology?

200

These are groups of cells that work together to perform a particular function.

What are tissues?

What are any two of: oxygen, carbon, hydrogen, or nitrogen?

200

The kidneys and bladder are part of this system.

What is the urinary system?

200

This part of the brain regulates body temperature.

What is the hypothalamus?

300

This tendency of the body maintains internal stability.

What is homeostasis?

300

These are composed of two or more tissue types and perform a specific function for the body.

What are organs?

300

These compounds ionize in solution and are capable of conducting electricity.

What are electrolytes?

300

This system includes the trachea, bronchi, and lungs.

What is the respiratory system?

300

This process of heat loss occurs when water evaporates from the skin.

What is sweating?

400

This type of feedback is used to control most homeostatic mechanisms in the body.

What is negative feedback?

400

This is the highest level of organization in the human body.

What is an organ system?

400

This type of bond involves a transfer of electrons and is common in salts.

What is an ionic bond?

400

This system protects the body against pathogens and includes white blood cells.

What is the immune system?

400

This involuntary rapid contraction of muscles helps generate heat when the body is cold.

What is shivering?

500

Childbirth and blood clotting are examples of this type of feedback.

What is positive feedback?

500

This system includes the brain, spinal cord, and nerves.

What is the nervous system?

500

This type of bond involves sharing electrons and is found in most organic molecules.

What is a covalent bond?

500

This system produces hormones and includes glands such as the thyroid and pituitary.

What is the endocrine system?

500

This term describes the body's ability to maintain a stable internal temperature despite changes in the external environment.

What is thermoregulation?
