• nervous system

• digestive system

• circulatory system

Which of the following is the best example of an organism maintaining homeostasis?

• a wolf panting after a chase

• a spider catching an insect in a web

• a mole digging tunnels in the ground

• a cricket becoming infected with a virus

The cells of the nasal cavity (nose) and the trachea are lined with cilia (small hairs). Which of the following describes a purpose of the cilia?

• to cool air that is entering the respiratory system

• to help move trapped particles out of the respiratory system

• to help produce sound as air moves out of the respiratory system

• to increase the surface area for gas exchange in the respiratory system

Emphysema is a sever respiratory system disease. The disease causes damage that directly prevents the transfer of oxygen to the bloodstream. Which part of the respiratory system does emphysema damage?

• alveoli

• bronchi

• larynx

• trachea

In which of the following ways does perspiring (sweating) help the body to maintain homeostasis?

• by decreasing body temperature

• by increasing sugar levels

• by increasing the amount of fluid in the body

• by reducing the amount of carbon dioxide in cells

The circulatory system is directly responsible for which of the following?

• breaking down food

• transmitting nerve impulses

• transporting nutrients to cells

• controlling movement of muscles

Which of the following is a body system response that adjusts body temperature when it is higher than normal?

• breathing rate begins to decrease

• blood vessels near the surface constrict (get smaller)

• sweat glands produce and secrete sweat

• hormones increase the metabolic rate of the liver

Which of the following best explains why oxygen diffuses from the alveoli into the blood?

• the diaphragm draws oxygen into the alveoli at a rapid speed

• alveoli cells contain hemoglobin to transfer gases to the blood

• the concentration of oxygen is greater in the alveoli than in the blood

• red blood cells move one at a time through capillaries surrounding the alveoli

The nose serves all of the following functions except

• providing an airway

• moisturizing inhaled air

• filtering dust and particles from inhaled air

• transferring oxygen from the air to the bloodstream
