This is the presentation that we use with our Biology B class when discussing our unit on the Animal Systems.

2. Cells—smallest unit of structure and function
of living things
Tissues—groups of cells working together to
perform a function

4. Covers the body surface and lines all body
cavities

13. Organs—groups of
tissues working
together to perform a
function
Organ Systems—groups
of organs working
together to perform a
function

14. The process by which organisms keep internal
conditions relatively constant by negative
feedback (feedback inhibition)

15. Process in which a stimulus produces a
response in the opposite direction
Example: Furnace, AC

16. 

Animal that generates its own body heat and
controls its body temperature from within
Examples: Birds, mammals, other mammals

17. 

Animal that relies on interactions with the
environment to help it control body
temperature
Examples: Turtles, snakes, other reptiles

19. Consist of brain, spinal cord and
peripheral nerves
Function—controls and
coordinates functions
throughout the body and
responds to internal and
external stimuli.

Dim the lights in a room.
After a few minutes, look at the eyes of
another person and note the size of the pupil
(the black center spot in the middle of the
eye).
Turn the room lights back on.
Check the size of the pupils again.
What happened?

25. 
The pupils should now be smaller. This is the
pupillary response: it "automatically" keeps
out excessive light that may damage the eye.

The knee jerk reflex is one that you may have
had tested at a check up at the doctor's
office. In this test, the doctor hits your knee
at a spot just below your knee cap and your
leg kicks out. Try it!
Have a partner sit with his or her legs crossed
so that his leg can swing freely.
Hit his leg just below the knee with the side
of your hand.
What happened?

27. 

The leg will kick out immediately (if you hit the
right place).
The knee jerk reflex is called a monosynaptic
reflex because there is only one synapse in the
circuit needed to complete the reflex. It only
takes about 50 milliseconds between the tap
and the start of the leg kick. That is fast! The
tap below the knee causes the thigh muscle to
stretch. Information is then sent to the spinal
cord. After one synapse in the ventral horn of
the spinal cord, the information is sent back
out to the thigh muscle that then contracts.

Get a ruler (or a yardstick or candy bar).
Hold the ruler near the end (highest number) and let
it hang down.
Have another person put his or her hand at the
bottom of the ruler and have them ready to grab the
ruler (however, they should not be touching the
ruler).
Tell the other person that you will drop the ruler
sometime within the next 5 seconds and that they
are supposed to catch the ruler as fast as they can
after it is dropped.
Record the level (inches or centimeters) at which
they catch the ruler (you can convert the distance
into reaction time with the chart below).
Test the same person 3 to 5 times (vary the time of
dropping the ruler within the 5 second "drop-zone"
so the other person cannot guess when you will
drop the ruler).

30. Consist of bones, cartilage, ligaments and
tendons
Function—supports the body, protects internal
organs, allows movement (joints), stores
mineral reserves, and provides a site for
blood cell formation.

33. Consist of skeletal muscle, smooth muscle and
cardiac muscle
Function—works with skeletal system to
produce voluntary movement, helps to
circulate blood and move food through the
digestive system

35. 


Skeletal
Smooth
Cardiac

37. Consist of skin, hair, nails, sweat glands and
oil glands
Function—serves as a barrier against infection
and injury, helps to regulate body
temperature, provides protection against
ultraviolet radiation from the sun

39. Consist of heart, arteries, veins, capillaries and
blood
Function—carries oxygen, nutrients, and
hormones to the cells of the body, helps fight
infection, carries cell waste to the kidneys,
helps regulate body temperature

43. Consist of the nose, pharynx, larynx, trachea,
bronchi, bronchioles and lungs
Function—provides oxygen needed for cellular
respiration and removes excess carbon
dioxide from the body

45. Consist of the mouth, pharynx, esophagus,
stomach, small intestine, large intestine and
rectum
Function—breaks down food into simpler
compounds that the cells of the body can
use, absorbs nutrient, absorbs water,
eliminates waste

48. 
Digestion Activity – Simulation

49. Helicobacter
pylori
Causes ulcers

50. Consist of the skin, kidneys, ureters, urinary
bladder, and urethra
Function—eliminates waste in ways that
maintain proper water and salt balance
(homeostasis)

52. Consist of the hypothalamus, pituitary, thyroid,
parathyroids, adrenals, pancreas, ovaries (in
females) and testes (in males)
Function—controls growth, development, and
metabolism, sexual maturity (reproduction),
also maintains homeostasis

54. Consist of the testes, epididymis, vasdeferens,
urethra, and penis (in males); fallopian tubes,
uterus, vagina (in females)
Function—produces reproductive cells, eggs in
females, sperm in males, provides for the
developing embryo

55. 

Consist of white blood cells, thymus gland,
spleen, lymph nodes, lymph vessels
Function—helps protect the body from
disease, collects fluid lost from blood vessels
and returns the fluid to the circulatory system
