- They secrete hormones internally into the blood capillaries.
- They are derived from connective tissue.
- They include the salivary glands.
ANSWER: b
- Which of these statements best describes an organ?
- a collection of cells that collectively carry out a body function
- a group of separate body structures that perform similar function, but come together to carry out activities that
- a structure made up of two or more different types of primary tissue that work together to perform a function
- a structure that the body could not survive without
are vital for survival
for the body
ANSWER: c
- Why do most cells depend on other cells of the body for survival?
- because cells do not contain fluid
- because all cells of the body are physically connected with one another
- because body cells cannot perform all life-sustaining functions on their own
- because most cells of the body do not directly interact with the external environment and therefore need other
cells to provide nutrients and remove wastes
ANSWER: d
- Which of these statements describes the internal environment?
- It consists of intracellular fluid.
- It is in direct contact with the body’s cells and consists of the extracellular fluid.
- It is inside the body but not in direct contact with the body’s cells.
- It is outside the body and keeps the fluid volume in unchanging composition.

- intracellular b. interstitial
- extracellular d. plasma
ANSWER: a
- What type of fluid is the fluid component of blood?

- It is the external environment of the body. b. It is the fluid inside each cell.
- It consists of plasma only. d. It consists of plasma and interstitial fluid.
ANSWER: d
- Which of these statements applies to homeostasis?
- It is a fixed state.
- It is only required for certain cells of the body to survive.
- Changes occur, but deviations from a set point are minimized.
- Only factors external to the body are capable of triggering responses designed to maintain homeostasis.
ANSWER: c
- Which of these factors is NOT under homeostatic regulation?
- sweat rate
- body temperature
- levels of waste products in the body
- levels of oxygen and carbon dioxide in the blood
ANSWER: a
- Which of these statements applies to the integumentary system?
- It eliminates unwanted substances from the body to the external environment.
- It consists of the heart, blood vessels, and lungs in the pulmonary cavity.
- It is important for protection of the body and also participates in temperature regulation.
- It is responsible for taking up required essential nutrients for the body.
ANSWER: c

- endocrine system b. integumentary system
- muscular system d. skeletal system
ANSWER: d
- Which of these statements describes negative feedback?
- A change in a regulated variable triggers a response by the effector that opposes the change.
- The input to a system increases the output, and the output limits its own production by inhibiting the input.
- A control system’s input and output continue to enhance each other in order to maintain homeostasis.
- It is the main operating principle of most of the body’s homeostatic control mechanisms.
