Science 1
Small air sacs that are at the end of each bronchiole
Alveoli
Connective tissue that forms part of the skeleton. It is found at the ends of bones and helps cushion them and reduce friction
Cartilage
An iron-rich molecule in red blood cells
Hemoglobin
The tube extending from the back of the nasal cavity and mouth to the esophagus that is the passage through which air passes to the larynx and food to the esophagus
Pharynx
Small colorless particles that release coagulating chemicals to form clots to stop the flow of blood
Platelets
The smallest blood vessels
Capillaries
A lower chamber of the heart
Ventricle
Strong bands of connective tissue that hold in the movable joints together
Ligament
A lower chamber of the heart
Ventricle
Works with the skeletal system to help a person move

How does good nutrition help the skeleton?
It provides the minerals, such as calcium and phosphorus, that are needed to make bones
How does running keep the body strong and healthy?
Running is a total workout. You work muscles in your legs, abdomen, and arms. In addition it works your heart and lungs.
How might a rock climber and runner train differently to maximize performance?
A rock climber may use different forms of exercise, like weight training and cardio workouts to strengthen the different muscle groups to prepare for climb
How are arteries and veins different?
The smooth muscle in arteries is thicker to assist in pumping oxygen-rich blood to the body. Veins have valves to ensure blood only flows in one direction back to the heart
