Question

which statement is true about how the nervous system works with other body systems? (2 points) the nervous system interacts with the circulatory system by sending signals to the heart to make more blood. the nervous system interacts with the skeletal system by sending signals to the legs to move fast. the nervous system interacts with the muscular system by sending signals to the ligaments to bond to tendons. the nervous system controls the digestive system by sending signals to the stomach, telling it to contract and digest food

Explanation:

• The heart does not make blood (red blood cells are made in bone marrow), so the first option is wrong.
• Ligaments connect bones to bones and tendons connect muscles to bones. The nervous system interacts with muscles (not ligaments) to cause movement, so the third option is wrong.
• The nervous system controls skeletal muscles (in legs etc.). When the nervous system sends signals to leg muscles (via motor neurons), it can cause the legs to move fast. The skeletal system provides structure and support, and the interaction here is about muscle - bone movement (but the key is the nervous - muscular interaction for movement).
• The digestive system has its own enteric nervous system, but the autonomic nervous system (a part of the peripheral nervous system) also influences it. However, the main interaction described in the fourth option is an over - simplification. The most accurate among the options is the second one as the nervous system (somatic nervous system) sends signals to skeletal muscles (attached to the skeletal system) to cause movement.

Answer:

The nervous system interacts with the skeletal system by sending signals to the legs to move fast.
