Define respiration
Creating useful energy from food
Define antagonist muscles
Muscles that work in pairs to control the movement of joints
Define joints
Where bone come together and they allow for controlled movement
Define cartilege
Flexible tissue that covers the end of bones at a joint
Define ligament
Fibers that hold bone to bone at the end of the joint
Define tendon

Define synovial joint
a common joint that is surrounded by a special membrane that lubricates the joint
Define breathing
the process of taking in (inhalation) and out of the lungs (exhalation)
Define Cellular respiration
Process in a cell that converts glucose and oxygen to create energy (CO2 is also given off)
Define trachea
The ribbed tube that carries air from the throat to the lungs
Define bronchiole
The small airways that passes through to the small alveoli
Define alveoli
The small air sacs where gas exchange occurs in the lungs
Define capillary
Give oxygenated blood from arteries to the tissues and deoxygenated blood from the tissues back into the veins. Essentially a bridge between the arteries and the veins
Define red blood cell
A cell in the blood that carries oxygen and carbon dioxide throughout the body
Define white blood cell
Cells found in the blood that help defend it from infection such as bacteria and viruses
