How do the circulatory, respiratory, and integumentary systems work together to heal a wound?

They interact during the healing process to provide closure, waste removal, reconstruction and protection.

Explanation:

The wound healing stages are made up of three basic phases: inflammation, proliferation and maturation.

The first phase of healing is inflammation, the body’s natural response to trauma. After the wound has been inflicted, homeostasis begins – the blood vessels constrict and seal themselves off as the platelets create substances that form a clot and halt bleeding. This is the integumentary system process with the circulatory system.

In the second wound healing stage, proliferation, the wound begins to be rebuilt with new, healthy granulation tissue. For the granulation tissue to be formed, the blood vessels must receive a sufficient supply of nutrients and oxygen. This involves both the circulatory and respiratory systems.

Maturation, also known as remodeling, is the last stage of the wound healing process. It occurs after the wound has closed up and can take as long as two years. During this phase, the dermal tissues are overhauled to enhance their tensile strength and non-functional fibroblasts are replaced by functional ones. Cellular activity declines with time and the number of blood vessels in the affected area decreases and recede. This is a coordination of circulatory system function along with continued integumentary system action.
