The basic unit of structure and function in living things
What are cells?
100
The process in which stimulus produces a response that opposes the original stimulus
What is feedback inhibition (negative feedback)
100
These are the structures of the respiritory system
What are the nose, pharynx, larynx, trachea, bronchi, bronchioles, and the lungs?
100
This system breaks down food, absorbs nutrients, and eliminates waste.
What is the digestive system?
100
This includes cells , tissues, organs, and organ systems
What are the levels of organization?
200
Epithelial, connective, nervous, and muscle
What are four types of tissue?
200
This describes the relatively constant internal physical and chemical condition that organisms maintain despite changes in internal and external environments
What is homeostasis?
200
Skin, hair, nails, and sweat and oil glands
What are the structures in the integumentary system?
200
This system transports oxygen, nutrients, and hormones to cells, fights infection, removes cell wastes, and helps to regulate body temperature.
What is the circulatory system?
200
Movements in the body are possible because of this.
What is muscle tissue?
300
A group of different types of tissue that works together to perform a single function or several related functions
What is an organ?
300
Maintenance of body temperature is a living example of this.
What is an example of achieving homeostasis through feedback inhibition?
300
These are the structures of the nervous system.
What are the brain, spinal cord, and nerves?
300
This system eliminates waste products from the body.
What is the excretory system?
300
These work together as a whole to maintain homeostasis.
What are the human body systems?
400
The brain and spinal cord are two examples of these
What are organ systems
400
The body responds to this by shivering
What is cold temperature?
400
Skeletal muscle, smooth muscle, and cardiac muscle
What are the structures of the muscular system?
400
This system controls growth, development, and metabolism, it also maintains homeostasis
What is the endocrine system?
400
A thermostat is a nonliving example of this.
What is homeostasis?
500
A group of cells that perform a single function
What is tissue?
500
One of the most important roles of this organ involves regulating the level of simple sugar.
What is the liver?
500
These are the structures of the skeletal system.
What are bones, cartilage, ligaments, and tendons?
500
This system helps protect the body from diseases, collects fluid loss from blood vessels and returns it to the circulatory system.
What is the immune system?
500
This organ is a part of the digestive system and one of the most important organs in homeostasis
