Verified step by step guidance

Step 1: Begin by understanding the concept of coordination of internal and external responses. This involves systems that regulate and communicate signals within the body to maintain homeostasis and respond to external stimuli.

Step 2: Recognize that the nervous system is primarily responsible for rapid communication and coordination of responses through electrical signals. It includes the brain, spinal cord, and peripheral nerves.

Step 3: Understand that the endocrine system complements the nervous system by using hormones to regulate slower, long-term processes such as growth, metabolism, and reproduction. Hormones are secreted by glands like the thyroid, adrenal glands, and pancreas.

Step 4: Compare the other systems listed in the problem. For example, the digestive and respiratory systems are involved in nutrient and oxygen exchange but do not primarily coordinate responses. Similarly, the integumentary and lymphatic systems focus on protection and immune defense, while the skeletal and muscular systems provide structure and movement.

Step 5: Conclude that the nervous system and endocrine system are the correct answer because they are the primary systems responsible for coordinating both internal and external responses in the body.
