Key Functions:

• Mediates involuntary contractions of internal organs.
• Controls blood vessel diameter and blood flow.
• Propels food through the digestive tract (peristalsis).
• Regulates organ size and pressure.

Interacting Systems & Components:

• Musculoskeletal System (type of muscle)
• Blood Vessel (forms walls of)
• Digestive Tract (forms walls of)
• Nervous System (regulated by autonomic nervous system)
