• Respiratory

How does the muscular system depend on the nervous system?

• The nervous system transports blood to the muscles.

• The nervous system provides support for the muscles.

• The nervous system supplies food and oxygen to the muscles.

• The nervous system sends signals to the muscles to cause movement.

• Digestive

• Endocrine

• Lymphatic

The purpose of the endocrine system is to regulate body functions through the use of hormones.

• True

• False

How does the excretory system maintain homeostasis?

• By breaking down food into smaller molecules.

• By working with the circulatory system to remove wastes from the blood.

• By preventing infection with macrophage production

• By producing white blood cells in the marrow

What organ is responsible for maintaining blood pressure and chemistry by regulating the amount of water and dissolved substances in blood? This organ filters out excess water-soluble nutrients and releases the waste material to the bladder for excretion.

• Kidney

• Stomach

• Liver

• Pancreas

Which of the following are part of the digestive system? (you may select as many as you feel are correct)

• Large Intestine

• Small Intestine

• Kidney

How does the human body maintain thermal homeostasis in extremely cold situations?

• muscles twitch and send a signal to the hypothalamus; the hypothalamus increases the blood flow to the surface of the skin to warm the skin and turn of the muscles

• receptors near the surface of the skin send a signal to the hypothalamus; the hypothalamus increases blood flow to the surface of the skin to keep it warm

• receptors near the surface of the skin send a signal to the hypothalamus; the hypothalamus sends a signal to the muscles to begin twitching which warms the blood circulating through the body

• the hypothalamus increases heart rate, lowers blood pressure, and decreases blood flow to the viscera so that all the warm blood is circulated to the surface of the skin to warm it
