Human Body Orientation

first test

responsiveness, growth, reproduction, movement, metabolism, maintain boundaries

6 basic functions of living organisms

anatomy

the study of structure and shape and the relationship fo one body area to another

physiology

the study of function - how body parts work together

atoms, cell, tissues, organs, organ systems, organism

6 levels of organization

gross anatomy

large body structures visible with the naked eye

microscopic anatomy

the study of microscopic body structures

yes - structure determines the function

is there a relationship between structure and function?

responsiveness

how fast the body can respond to stimuli

growth

the reproduction of new cells

movement

the movement of parts of an organism

metabolism*

a rate of chemical reactions that produce energy*

reproduction

the creation of more of an organism

maintain boundaries

skin protecting the body from the outside world

nutrients, oxygen, stable body temperature, water, appropriate atmospheric pressure

what do living things need in order to survive? (5 things)

98.6

what should body temperature be

homeostasis

tendency of the body’s systems to maintain a relatively constant or balanced internal environment

metabolism

ALL chemical reactions occurring in the body

urinary*

system that rids the body of nitrogen-containing wastes*

endocrine

system that is affected by the removal of the thyroid gland

skeletal

system that provides support and levers on which the muscular system can act

cardiovascular*

system that includes the heart*

integumentary

system that protects underlying organs from drying out and mechanical damage

lymphatic

system that system that protects the body by destroying bacteria and tumor cells

digestive

system that breaks down foodstuffs into small particles that can be absorbed

respiratory

system that removes carbon dioxide from the blood

cardiovascular

system that delivers oxygen and nutrients to the body tissues

muscular

system that moves the limbs; allows facial expression

urinary

system that conserves body water or eliminates excesses

reproductive

system that provides for conception and childbearing

endocrine*

system that controls the body with chemicals called hormones*

integumentary*

system that is damaged when you cut your finger or get a severe sunburn*
