The groups listed below are sets of activities that help maintain homeostasis.

Group 1: Carbon dioxide removal; Blood sugar levels; Blood composition

Group 2: Waste removal; Water balance; Blood pH

Group 3: Blood sugar levels; Water balance; Blood pressure

Group 4: Detoxification; Temperature; Blood composition

Which group of activities is regulated by the kidneys to aid in homeostasis of the body?

• Group 1

• Group 2

• Group 3 

• Group 4

Which of these systems functions to protect and support vital organs?

• Digestive

• Skeletal

• Nervous

• Excretory

Which of the following results when a person’s hand is near an open flame?

• Neurons activating the muscles of the hand cause the hand to move.

• Cilia process incoming information and determine a response.

• T-cells integrate incoming and outgoing information.

• White blood cells detect the change in temperature of the environment.

While collecting wildflowers, a student begins to sneeze and has itchy, watery eyes. What bodily system causes this reaction?

• Immune

• Nervous

• Muscular

• Circulatory

Which of these is a nonspecific defense function of the skin against infection?

• Skin produces phagocytes which eat and destroy pathogens.

• Skin induces cytotoxic cells to kill disease causing pathogens.

• Skin causes swelling and heat on the epidermal surface to kill pathogens.

• Skin contains oil glands which secrete sebum to prevent the entry of pathogens.

Which organ is the site of gas exchange between the body and the environment?

• Spleen

• Liver

• Lungs

• Pancreas

Which of these helps control blood glucose levels?

• The immune system removes excess blood glucose as a line of defense.

• The endocrine system releases a hormone that balances blood glucose levels.

• The digestive system releases an enzyme that stabilizes blood glucose levels.

• The reproductive system absorbs excess blood glucose as an embryonic nutrient.

When specific hormones are present in the blood of a hen, an egg is released from an ovary. Which two systems are involved with the release of an egg?

• Immune and digestive systems

• Digestive and endocrine systems

• Reproductive and immune systems

• Endocrine and reproductive systems

The diagrams identify major parts of two different human systems.

• Both systems provide structure to the body.

• Both systems contain specialized cells and tissues.

• Both systems assume the functions of other failing body parts.

• Both systems establish homeostasis and communication.

Which immune system function is carried out by antibodies?

• Antibodies produce proteins that attach to an invading virus.

• Antibodies attach to an invading virus as a target marker.

• Antibodies engulf the invading virus as a defense mechanism.

• Antibodies release enzymes that lyse the invading virus.
