,8. What is the smallest unit of matter to be involved with a. Atoms.
chemical reactions?
9. What are "structures of definite form that are a. Organs.
composed of two or more different tissues and have
specific functions".
10. What are the eleven (11) systems of the human body? a. Integumentary, skeletal, muscular, nervous, endocrine, cardiovascular,
lymphatic, respiratory, digestive, urinary, and reproductive.
11. What is meant by "palpation"? Give one example of a. Nurse feels body surfaces with the hands; an example would be pulse and
palpation in an assessment... heart rate determination.
12. What is "auscultation"? a. Listening to body sounds such as heart, abd, and lungs.
13. What is meant by "percussion"? Is this typically done a. Using fingers or a tool to tap on the body and listen to the resulting echo,
by an RN? this is now normally only done by advanced practice nurses (CRNPs, etc.).
14. What is "metabolism"? a. Sum of all chemical processes that occur in the body (including catabolism
and anabolism).
15. What is "responsiveness" as it relates to organisms? a. Ability to detect and respond to changes in the external or internal
environment.
16. What does "movement" include when we are a. Movement includes motion of the whole body, individual organs, single cells,
discussing commonalities among organisms? or even organelles inside cells.
17. What do the terms "growth", "reproduction", and a. Growth refers to an increase in size and complexity, due to an increase in the
"differentiation" mean in regards to organisms? number of cells, size of cells, or both. Differentiation is the change in a cell
from an unspecialized state to a specialized state. Reproduction refers either to
the formation of new cells for growth, repair, or replacement, or the
production of a new individual.
18. What is the definition of homeostasis? a. A condition of equilibrium in the body's internal environment produced by
the ceaseless interplay of all the body's regulatory processes.
19. What is fluid inside body cells called? a. Intracellular fluid.
20. What is fluid outside of body cells called? a. Extracellular fluid.
21. What are the two (2) main places that extracellular a. 1. ECF filling the narrow spaces between cells of tissues is called interstitial
fluid is found? fluid, intercellular fluid, or tissue fluid. 2. ECF in blood vessels is termed plasma,
within lymphatic vessels it is called lymph, in and around the brain and spinal
cord it is called cerebrospinal fluid, in the joints it is called synovial fluid and
within the eyes it is called aqueous humor or vitreous humor.
, 22. What two (2) body systems regulate homeostasis? a. Nervous and endocrine systems.
23. How does the nervous system regulate a. Detects changes and sends nerve impulses to counteract the disruption.
homeostasis?
24. How does the endocrine system regulate a. Secretion of hormones.
homeostasis?
25. Which system of regulating homeostasis tends to a. Whereas nerve impulses (nervous system) cause rapid changes, hormones
work more quickly and which works more slowly to (endocrine system) usually work more slowly.
maintain homeostasis?
26. What is a "feedback system"? a. A cycle of events in which information about the status of a condition is
continually monitored and fed back (reported) to a central control region.
27. What are the three (3) basic components of a a. A receptor - monitor changes in a controlled condition and sends input to a
feedback system? control center, control center - sets the range of values within which a
controlled condition should be maintained, evaluates input, and generates
output commands, effector - body structure that receives output from the
control center and produces a response.
1. What is the difference between a negative and a a. If a response reverses the original stimulus - the system is a negative
positive feedback loop? feedback system, if a response enhances the original stimulus - the system is a
positive feedback system.
29. How is homeostasis of blood pressure an example a. If a stimulus (stress) causes blood pressure (controlled condition) to rise,
of a negative feedback loop? pressure-sensitive cells (baroreceptors) in certain arteries send impulses (input)
to the brain (control center). The brain sends impulses (output) to the heart
(effector), causing the heart rate to decrease (response) and return of blood
pressure to normal (restoration of homeostasis). The activity of the effector
produces a result, a drop in blood pressure that opposes the stimulus, an
increase in blood pressure.
30. How is (normal) child birth an example of a positive a. When labor begins, the uterus is stretched (stimulus) and stretch-sensitive
feedback loop? nerve cells in the cervix of the uterus (receptors) send impulses (input) to the
hypothalamus (control center). The hypothalamus causes the release of
oxytocin (output) which stimulates the uterus (effector) to contract more
forcefully (response). Movement of the baby's head down the birth canal
causes further stretching, the release of more oxytocin, and even more forceful
contractions. The cycle is broken with the birth of the baby.
