Biting flies can transmit diseases and cause loss of blood for animals in nature. Horses have developed behaviors to repel biting flies such as ear twitching, head tossing, leg stomping, and tail swishing.

Which statement best describes the interaction between body systems that allows horses to repel biting flies?

Both the respiratory system and the digestive system involve the uptake of necessary molecules from an animal's surroundings. Alveoli are tiny sacs that aid in the exchange of carbon dioxide and oxygen in the lungs. Intestinal villi are tiny projections along the lining of the intestines used to take in nutrients from food passing through.

Which system must interact with the respiratory and digestive systems to transport gases and nutrients throughout the body?

The female reproductive and endocrine systems work interactively for which main purpose?

Which statement best describes an interaction between the muscular system and the respiratory system?

How do the circulatory system and immune system work together to respond to an injury?

When the skin comes in contact with an irritant, receptors in the skin send signals to the spinal cord. The signal is then sent to the brain for processing, and the individual begins to scratch the affected area.

Which two systems are most likely interacting when a person experiences itching caused by a skin irritant?

Breaking down food for nutrients involves many body systems. A student made a partial list of the processes that occur.

Which body systems interact most directly in the three listed processes?

Which four body systems interact to allow a person to sneeze?

The fuzzy millipede, Polyxenus fasciculatus, is found in Texas and is preyed upon by most species of ants. To protect itself against the ants, it ejects fibers from a tuft located at the tail end of its body. The tufts have hooks at the tips and barbs along their length that lock and interlink with the ant’s setae, small hairs that cover the body of the ant.

When an ant attacks, the millipede flexes its back end toward the ant and wipes the tufts against it. As the ant attempts to remove the tufts, it entangles itself more, becoming immobilized.

Which two systems most directly interact in the fuzzy millipede’s defense against ants?

A feedback mechanism in the human body is shown.

Based on this diagram, which two systems interact to maintain homeostasis?

Regulation is the process of body systems working together to maintain homeostasis despite variation in external conditions. Two major systems help detect and coordinate the response to changes in the environment.

Negative feedback is one example of regulation. If blood sugar gets too high, a signal is sent and the hormone insulin is secreted by the endocrine system. In response, the liver removes glucose from the blood and stores it as glycogen.

WHAT OTHER SYSTEM, BESIDES THE ENDOCRINE, IS INVOLVED IN THE DETECTION AND RESPONSE TO THE EXTERNAL CONDITIONS?
