200

Thick, muscular walls to support high pressure while carrying blood away from the heart

What are arteries?

200

Primary Organs of Respiration

What are the Lungs?

200

Controls involuntary functions such as heart rate and digestion

What is the Autonomic Nervous System?

200

These carry oxygenated blood to the body tissues

What are Systemic Arteries?

300

Maintains cell shape and facilitates cell movement

What is the Cytoskeleton?

300

Thinner walls with valves to prevent backflow while carrying blood back to the heart.
