Answer 1

## Step1The first question is about the body systems that interact to allow a person to sneeze. Sneezing is a reflex action that involves several body systems. The respiratory system is involved as it is the system that is directly involved in the sneezing process. The nervous system is involved as it sends signals to the muscles involved in sneezing. The muscular system is involved as it is the system that carries out the sneezing action. The immune system is involved as it is the system that fights off the irritants that cause the sneeze.## Step2The second question is about the body systems that interact when a person experiences itching caused by a skin irritant. The integumentary system is involved as it is the system that includes the skin, which is the site of the irritant. The nervous system is involved as it sends signals to the brain in response to the irritant, which then sends signals back to the skin to scratch the affected area.
