Organ systems
A group of two or more organs working together for a specific job; e.g. the digestive system
Circulatory System
The body system responsible for moving oxygen, carbon dioxide and nutrients throughout the body. Includes the veins, arteries, capillaries, and heart.
Respiratory system
The body system in which oxygen is brought into the body and carbon dioxide is released
Mechanical digestion
Includes grinding or chewing your food when you eat
Digestive System
The body system that takes in, breaks down, and absorbs nutrients that are necessary for growth
Chemical digestion
Changes the composition of food by breaking it down such as with stomach acids
Excretory system
The body system that helps rid the body of wastes, toxins, and excess water. Includes the bladder, ureters, kidneys, and urethra
Nervous system
The body system of specialized cells that carry electrical messages throughout the body
Nervous System
Includes the brain, spinal cord, & peripheral nerves
Muscular System
The body system that supports the body and enables it to MOVE
Muscular System
Major organs include skeletal muscles, smooth muscles, and cardiac muscles
Skeletal System
The body system that protects and supports the body
Integumentary System
The body system that covers and protects the body from the environment. Includes the hair, nails, and skin.
The Body's first layer of defense
Integumentary System
Immune System
To kill pathogens that have invaded the body
Immune System
This system explains why the body aches, has a fever , and vomits
Endocrine System
Organ system that is responsible for producing hormones that travel through the blood stream to maintain homeostasis
Kidney
Filters wastes from the blood
Joint
Area that allows movement where bone meets bone
Bladder
a smooth muscular sac that is a storage for liquid wastes
Villi
Structures found in the small intestine that increase surface area to allow the more nutrients to be passed into the blood.
Aveoli
The area in the lungs where gas exchange occurs
Ovary
Female reproductive organ where eggs are formed.
Uterus
Female reproductive organ where an embryo is implanted.
Vaccine
A substance injected into the body that helps create antibodies against the disease it is made for (i.e. measles).
Sensory neuron
Sends signals from the environment to the brain
Motor neuron
Sends signals from the brain to the muscles
Hinge-joint
Formed between 2 bones that allows only one direction of movement, such as a door.
Bone Marrow
Area inside a bone that makes blood cells
Tendon
Area where muscles attach to bone
Ligament
Area where bone attaches to bone
Arteries
Carries blood from the heart to the body (usually depicted as red vessels)
Veins
Carries blood from the body to the heart (usually depicted as blue vessels)
Capillaries
Small blood vessels that allow the exchange of oxygen, carbon dioxide, and nutrients.
Adrenal Glands
Part of the endocrine system that creates adrenaline. Can be responsible for flight-or-fight response
Stimulus
any event or situation that evokes a response
response
An action or change in behavior that occurs as a result of a stimulus.
Internal stimulus
scared, breathing rate increases
External Stimulus
Anything outside the body of the organism that can cause a response in an organism
chemical digestion
Process by which enzymes break down food into small molecules that the body can use
physical digestion
The mechanical breakdown of large food particles into smaller ones
