Unit Review
Here is what we have learned from this unit:
- The human body is a single structure but it is made up
of billions of smaller structures of four major kinds: cells,
tissues, organs, and systems.
- An organ is an organization of several different kinds
of tissues so arranged that together they can perform a
special function.
- A system is an organization of varying numbers and kinds
of organs so arranged that together they can perform complex
functions for the body.
- Ten major systems include the skeletal, muscular, nervous,
endocrine, cardiovascular, lymphatic, respiratory, digestive,
urinary, and the reproductive system.
- Body functions are the physiological or psychological
functions of body systems. Survival of the body depends
on the body's maintaining or restoring homeostasis, a state
of relative constancy, of its internal environment.
- Human life process includes organization, metabolism,
responsiveness, movements, reproduction, growth, differentiation,
respiration, digestion, and excretion. All these processes
work together, in fine-tuned balance, for the well-being
of the individual and to maintain life.
- Life depends on certain physical factors from the environment,
which include water, oxygen, nutrients, heat, and pressure.
- Useful terms for describing body parts and activities
include:
- Directional terms
- Terms describing planes of the body
- Terms describing body cavities
Quiz
It's time to see how much you have learned from this unit.
A multiplechoice quiz has been created to give you an opportunity

Since the quiz is created as an incentive for learning, rather
than an objective evaluation of learning results, the score
of the quiz will not be recorded. Instead, feedback to your
answer is provided instantaneously. So, you may select another
choice if your first choice is not the correct one.
These quiz questions are grouped into several sets of two
questions each to reduce the size of the content on each page.
