The human
... [Show More] body is a system because - ANS-It is made up of cells,
tissues, organs, organ systems
Mechanical digestion - ANS-This process occurs by chewing in the
mouth and by churning in the stomach. There is no chemical change
in the substances, only a physical change.
Chemical digestion - ANS-This process is a chemical reaction that
occurs with the help of digestive chemicals, such as enzymes, to
change food into substances that can be absorbed and used in the
body. Takes place in the mouth, stomach, and small intestine.
mechanical digestion - ANS-takes place in the mouth and stomach
chemical digestion - ANS-takes place in the mouth, stomach and
small intestine
cells - ANS-evidence that an organism is ALIVE. The smallest unit
that can perform all of the functions necessary for life
- The basic unit of structure and function in living things
if cells were placed in a beaker of salt water... - ANS-water would
leave the cells and they would shrink
if salty cells were placed in a beaker of water... - ANS-water would
move into the cells and they would grow
the circulatory system delivers nutrients to - ANS-all the cells all
over the body
nutrients leave the blood and enter cells through - ANS-diffusion
glucose reacts with_____________to produce energy in the cells -
ANS-oxygen
There is ___________ oxygen in the air you exhale compared to the air
you inhale - ANS-less
oxygenated blood goes from the _____________ to the cells via
diffusion - ANS-lungs
digestive and ________________ are systems are responsible for
breaking down the food into glucose and then carrying it to all of our
cells. - ANS-circulatory
the circulatory and respiratory systems work together by... - ANSyour lungs (resp. system) supply oxygen carried by blood (circ.
system) to the cells, and then the blood carries the CO2 back to the
lungs to exhale
The respiratory system... - ANS-exchanges gases (oxygen - O2 and
Carbon dioxide - CO2) with the environment
Red blood cells - ANS-carry oxygen to our cells and CO2 to our lungs
to exhale
cell wall - ANS-A strong, rigid structure found on the outside plant
cells; protects the cell.
cell membrane - ANS-A semi-permeable layer that separates the
outside of a cell from the inside of the cell; it regulates what goes
into and out of the cell.
Mitochondria - ANS-The powerhouse of the cell. Provides us with
energy.
Nucleus - ANS-An organelle found inside plant and animal cells that
surrounds the DNA; the ''control
center'' of the cell.
Cytoplasm - ANS-The watery fluid found on the inside of all cells.
This fills up the cell and is where organelles sit.
The nervous sytem - ANS
-coordinates all other body systems...Processes sensory input and
transmits signals to the body
your fingertips are more sensitive than your elbows because... -
ANS-they contain more sensory neurons
When you exercise you r energy needs go... - ANS-up!
Breathing and heart rate go down after exercise because... - ANSyour energy needs go down
Our cells need oxygen to... - ANS-react with glucose to release
energy for our cells
Levels of organization - ANS-cell, tissue, organ, organ system,
organism [Show Less]
