• regulate blood pressure

What transports substances around the body?

• Blood
• Sweat
• Tears
• Urine

When you get cut, your skin cells release hormones that signal platelets to come and stop the bleeding. Platelets then release more hormones that signal even more platelets to help stop bleeding. The hormone signals continue until the cut is closed.
