Basic Concepts
This is the study of the structure and shape of the body and body parts.
What is anatomy?
This is the basic unit of structure and function in living things.
What is a cell?
This is the most abundant element in the human body.
What is oxygen?
This system is responsible for breaking down food and absorbing nutrients.
What is the digestive system?
The normal human body temperature in Fahrenheit.
What is 98.6°F?
This is the study of how the body and its parts work or function.
What is physiology?
These are groups of cells that work together to perform a particular function.
What are tissues?
Name two of the four most common elements in the human body.
What are any two of: oxygen, carbon, hydrogen, or nitrogen?
The kidneys and bladder are part of this system.
What is the urinary system?
This part of the brain regulates body temperature.
What is the hypothalamus?
This tendency of the body maintains internal stability.
What is homeostasis?
These are composed of two or more tissue types and perform a specific function for the body.
What are organs?
These compounds ionize in solution and are capable of conducting electricity.
What are electrolytes?
This system includes the trachea, bronchi, and lungs.
What is the respiratory system?
This process of heat loss occurs when water evaporates from the skin.
What is sweating?
This type of feedback is used to control most homeostatic mechanisms in the body.
What is negative feedback?
This is the highest level of organization in the human body.
What is an organ system?
This type of bond involves a transfer of electrons and is common in salts.
What is an ionic bond?
This system protects the body against pathogens and includes white blood cells.
What is the immune system?
This involuntary rapid contraction of muscles helps generate heat when the body is cold.
What is shivering?
Childbirth and blood clotting are examples of this type of feedback.
What is positive feedback?
This system includes the brain, spinal cord, and nerves.
What is the nervous system?
This type of bond involves sharing electrons and is found in most organic molecules.
What is a covalent bond?
This system produces hormones and includes glands such as the thyroid and pituitary.
What is the endocrine system?
This term describes the body's ability to maintain a stable internal temperature despite changes in the external environment.
What is thermoregulation?
