Describe the interrelationship between at least two different body systems and how they maintain homeostasis.

I was thinking maybe the cardiac and skeletal system.  Or maybe something to do with the endocrine system and something else.  I am trying to steer away from the nervous system.

Homeostasis is the maintenance of a stable internal environment in the body. Homeostatic regulation is controlled by the release of hormones into the bloodstream, or through control via the nervous system. The receptor senses changes in the environment and sends information to the control center, which determines a response to the stimulus or change. Signals are sent to the effector--a muscle or gland or other target organ, and either some type of positive or negative feedback occurs. An example is the maintenance of the blood sugar levels of glucose. If a meal is consumed and sugar levels increase, the hormone insulin is secreted from the pancreas. This causes some of the sugar to be transported to the cells for their use. However, if the sugar level within the cells is too high, this stimulus causes some of it to be converted to glycogen to be stored in the muscles and liver. When sugar levels are low, the hormone glucagon allows cells to break down the stored glycogen and convert it back to glucose to help maintain the sugar levels. Another example of homeostasis is how blood pressure is regulated. Blood vessels can act as receptors because they can sense resistance of blood flow against the walls of the vessels. If this occurs, a message is sent to the brain. Here, the brain sends a message to the effectors--both the heart, which controls heartrate and the pulse, and to the blood vessels. The blood vessels would increase their diameter and this would in turn, lower the blood pressure and the heart rate would slow down. When pressure is too low, the opposite occurs.  These homeostatic mechanisms work well if the body is free of disease. However, if someone has diabetes or heart disease, they may need to take medication if the body is unable to maintain homeostasis.
