Health-care workers are exposed to many different types of pathogenic microorganisms.
Which body systems work together to protect the body from pathogens?

• Muscular and vascular
• Digestive and excretory
• Circulatory and immune
• Endocrine and reproductive

Research has led scientists to conclude that fevers help the human body fight infection by elevating body temperatures and causing parts of the immune system to work better.
Which statement does this conclusion best support?

• Fevers are a disruption of homeostasis.
• Fevers should immediately be treated with medication.
• Fevers are a necessary part of maintaining homeostasis.
• Fevers are rarely caused by bacterial infections

A biology student is studying the digestive system. He found research indicating that more bacteria live in the large intestine than there are cells in the human body.
Based on this research, which of these can he logically conclude?

• Bacteria are necessary for digestion to occur.
• Bacteria are produced by the human body.
• The large intestine is made of bacteria.
• The large intestine is diseased.

Which two body systems are involved in moving the person’s leg shown in the diagram below away from the table leg?

• Integumentary system and nervous system
• Muscular system and nervous system
• Nervous system and immune system

Hummingbirds need large amounts of energy to flap their wings between 60 and 200 times per second. Their wings beat so rapidly that it is difficult to see them move. They often appear suspended in air for extended periods of time without changing their location. Hummingbirds have long bills and grooved tongues to reach into flowers to feed on flower nectar. They also feed on insects.
The body system most directly interacting with the skeletal system to enable hummingbirds to beat their wings between 60 and 200 times per second is the--

• digestive system
• endocrine system
• muscular system
• circulatory system

The human body is composed of different systems made of specialized cells, tissues, and organs.Each of these structures has a specific function that aids in the survival of the human species.
Which organs are used in reproduction?

• Brain, spinal cord, and eyes
• Mouth, stomach, and gallbladder
• Lungs, esophagus, and heart
• Ovaries, uterus, and fallopian tubes

A wildlife biologist is investigating the sudden increase in the death rate among several bird species. She has not been able to determine what disease or toxin is causing the deaths, but she has found that many of the sick birds are exhibiting a shortage of dissolved oxygen and a buildup of dissolved carbon dioxide in their cells.
Which of these body systems in the sick birds is most likely functioning improperly?

• Muscular
• Excretory
• Circulatory
• Reproductive
