Body Systems and Homeostasis Review

A person develops an elevated body temperature from a bacterial infection. The fever is a response from the body to help fight the infection by

• slowing the growth of the bacterial growth

• increasing the amount of water in the body

• increasing the body's heart rate

• stopping additional bacteria from entering the body

Which of the following stimuli is least likely to cause an animal to vomit?

• a bacterial infection in the stomach

• feeling cold after stepping outside

• drinking large amounts of water at once

• getting dizzy after spinning in circles

A young boy received a dog for his birthday. After a few weeks, he became aware of several stimuli which would create responses in the dog. He recorded the information into a chart shown below.

Based on the data, which responses were caused by an internal stimulus?

• II only

• IV only

• I and III

• I, II, and III

Which stimulus is most likely to cause a cat to respond by increasing the internal body temperature above the normal level?

• long exposure to cold external temperatures

• digestion of food occurring in the stomach

• a viral infection of the cells in the lungs

• an increased heart rate after running

The main function of the excretory system is to

• produce enzymes to help digest food

• collect and remove waste products from the body

• prevent diseases and fight infections

• carry oxygen and nutrients to the body's cells

Two body systems work together to help remove waste products from blood. What are these two systems?

• circulatory and excretory

• skeletal and digestive

• circulatory and integumentary

• muscular and excretory

What body systems are described in the concept map?

• circulatory and excretory

• endocrine and circulatory

• excretory and endocrine

• respiratory and excretory

A zebra grazing in the savannah sees a nearby lion charging to attack and eat the zebra. Which of the following is the most likely to respond of the zebra?
