Front 1

define homeostasis

Back 1

constant conditions maintained in the body which may vary but are relatively constant; the condition on which the body's internal environment remains relatively constant within certain physiological limits.

Front 2

Front 4

what is the anatomical position?

Back 4

Person standing forward

Front 5

superior position in the body?

Back 5

toward the head or the upper part of a structure
example: the heart is superior to the liver

Front 6

inferior position of the body

Back 6

away from the head or the lower part of a structure
example: the stomach is inferior to the lungs

Front 7

anterior position in the body

Back 7

nearer to or at the front part of the body
example: the sternum is anterior to the heart

Front 8

posterior position in the body

Back 8

nearer to or at the back part of the body
example: the esophagus is posterior to the trachea

Front 9

medial position in the body

Back 9

nearer to the midline which is an imaginary line that divides the body into equal right and left sides

Front 10

lateral position in the body

Back 10

farther from the midline
example: the lungs are lateral to the heart

Front 11

intermediate position in the body

Back 11

between two structures

Front 12

ipsilateral position in the body

Back 12

on the same side of the body as another structure

Front 13

contralateral position in the body

Back 13

on the opposite side of the body as another structure

Front 14

proximal position in the body

Back 14

nearer to the attachment of a limb to the trunk; nearer to the origination of a structure

Front 15

distal position in the body

Back 15

farther from the attachment of a limb to the trunk; farther from the origination of a structure

Front 16

superficial (external) position in the body

Back 16

toward or on the surface of the body
example: the ribs are superficial to the lungs

Front 17

deep (internal) position in the body

Back 17

away from the surface of the body

Front 18

what happens in the chemical level of structural organization?

Back 18

atoms to molecules

Front 19

what happens in the cellular level of structural organization?

Back 19

molecules are organized into cells

Front 20

what happens in the tissue level of structural organization?

Back 20

groups of similar cells work together

Front 21

what happens in the organ level of structural organization?

Back 21

two or more tissue become an organ

Front 22

what happens in the system level of structural organization?

Back 22

related organs with common functions

Front 23

what happens in the organismal level of structural organization?

Back 23

all of the cells, tissues, and organ systems become a human being

Front 24

Metabolism

Back 24

All of the chemical processes of life

Front 25

responsiveness

Back 25

Listen systems detect and respond to changes it in their environment

Front 26

Differentiation

Back 26

the process of cellular specialization

Front 27

Reproduction

Back 27

Both cells and organisms make copies of themselves

Front 28

extracellular fluid and an example of it

Back 28

fluid outside of the cell
example: plasma

Front 29

intracellular fluid and an example

Back 29

fluid inside of the cell
example: cytoplasm

Front 30

six components of a feedback system

Back 30

1. sensor which detects change
2. circuit which carries signals to the control center
3. effector aka response which produces the effect
4. response which is the output from the effector
5. feedback which is the response detected by the sensor
6. shut-off which is where the sensor reacts to normalization

example: a thermostat

Front 31

what are the two types of feedback systems?

Back 31

1. negative: response reverses stimulus and brings it back to balance and stabilizing

2. positive: response enhances stimulus and keeps going out of balance a good example where it's useful is during labor

Front 32

what are the two type of cells

Back 32

1. prokaryotic which is bacteria
2. eukaryotic which is all other life forms

Front 33

eukaryotic cells are made up of what three parts

Back 33

1. plasma membrane
2. cytoplasm which contains organelles surrounded by cystol
3. organelles which includes the nucleus and that contains the chromosomes of the cell

Front 34

what are eukaryotic cell components ?

Back 34

cell membrane
cytoplasm
organelles
inclusions
cell wall
