Human Body Systems
Describe how this system works with one other
system to perform a
Soft connective tissue
found in spaces in bone
3 Types of
How does the skeletal system work with the muscular system?
- Muscles not under your conscious control
• Ex: muscles used for
breathing & digesting food
– Muscles that are under your
• Ex: Smiling, turning the
pages in a book,
walking to class
produces the body’s
Connective tissue that is
more flexible than bone
– Ex: nose, tops of ears,
ends of bones
together to form joints
1. Provides shape & support
2. Helps you move
3. Protects organs
4. Produces blood cells
5. Stores certain fat
Skull … protects the brain
Ribs … protect the heart & lungs
Vertebrae … protects the spinal cord
Femur … produces blood cells in the leg
Humerus … produces blood cells in the arm
bones & move
bones using tendons
attaching muscles to bones
in the heart

(unlike skeletal muscles)
Muscles move by

Why is the digestive system so important for the human body?
Parts & Roles of
Breaks down food
into molecules the
body can use.
Molecules are absorbed
into the blood & carried
throughout the body
(by the circulatory system).
Wastes are eliminated
from the body
(by the excretory system)
molecules of food
digestion starts here
Muscular tube connecting
the mouth to the stomach
moves the food
digestion takes place
with the help
of digestive juices
(enzymes & acids)
Most of the
takes place over 5-6 hours
digested food into
is readied for
from the body
into solid form
Path of Air
into the Body

other system to perform a specific function.

in breathing, moves downward on the inhalation and upward during exhalation.

about what is
inside & outside
of the body.
Directs the way your body
• Interprets input from the senses
• Controls movement of skeletal muscles
• Complex mental processes (learning)
• Coordinates muscle
actions & balance
• Controls involuntary actions (ex: breathing)
brain & the rest
of the body
– Nerve cell that is specialized to transfer messages
in the form of fast-moving electrical energy
– electrical messages are called impulses
of the Circulatory System
The Cardiovascular System
substances to cells and carries
Hollow, muscular organ that pumps blood throughout
– Blood vessel that carries oxygen-rich blood away
from the heart and to the body parts.
– Small blood vessels where materials are
exchanged between the blood and the
body’s cells (oxygen & carbon dioxide)
– Carries oxygen-poor blood (w/carbon dioxide)
back to the heart (to be pumped out to the lungs)
• Blood is made of 4 components
– liquid part of blood
2. Red blood cells
– take up oxygen in the lungs and deliver it to cells
3.White Blood Cells
– the body’s disease fighters(part of immune system)
– cell fragments used in forming blood clots (that make scabs)
How does the circulatory system help with the digestive system?

1. alveoli: The tiny air sacs at the end of the bronchi in the lungs.
2. aorta: The main transporter of blood and the largest artery.
3. arteries: The blood vessels that carry oxygenated blood away
from the heart.
4. atrium: The two upper chambers of the heart.
5. axon: The single, long strand that comes out of the other side of
the cell body.
6. bones: Give the basic shape to the body. An adult has 206 of
7. brain: The main control center of the nervous system.
8. brain stem: The part of the brain responsible for controlling
vital functions such as heartbeat, breathing, and blood pressure.
9. capillaries: The smallest vessels that connect the arteries and
10. cell body: The main part of a neuron.
11. cerebellum: The part of the brain responsible for smooth,
12. cerebrum: The part of the brain responsible for learning,
reasoning, memory, and the senses.
13. circulatory system: The human body system that transports
oxygen and nutrients to the body, takes carbon dioxide back to
the lungs, and fights infections with white blood cells.
14. dendrites: The short strands branching out from the cell body
of a neuron.
15. diaphragm: The dome-shaped muscle found under the rib cage
which is important for breathing.
16. digestive system: The human body system that breaks down
food to be used throughout the body.
17. epiglottis: The flap of tissue that prevents food from entering the
18. esophagus: The muscular tube food passes through to get to the
19. fracture: A break in a bone.
20. gallbladder: A storage sac that holds the bile produced by the
21. heart: The organ that pumps blood throughout the body.
22. involuntary muscles: Muscles that automatically do their jobs
without you needing to think about it.
23. joint: The place where two or more bones meet.
24. large intestine: A tube-like organ that absorbs water from food.
25. ligaments: Strong bands of connective tissue that holds the
bones in a joint together.
26. liver: Produces bile.
27. marrow: The soft tissue in the middle of a bone which produces
new blood cells.
28. muscular system: The human body system that causes
movement of the body parts and also helps with digestion and
29. nervous system: The human body system that controls the
body's reactions to the outside world. It is the system that
controls the actions, emotions, thoughts, memories, sensations,
30. neurons: Another word for nerve cells which carry messages
throughout the body.
31. nose: Where air is inhaled, filtered, warmed and moistened.
32. pancreas: Produces pancreatic juices used in digestion.
33. peristalsis: The muscular action which helps move food
through the esophagus and through the rest of the digestive
34. plasma: One part of the blood which is mostly water and makes
up half the blood.
35. rectum: The place where solid waste is stored.
36. respiratory system: The human body system that provides
oxygen through breathing.
37. saliva: The secretion from the salivary glands.
38. salivary glands: The place where saliva is stored and then
secreted into the mouth.
39. skeletal system: The human body system that supports the body
and gives it shape, protects internal organs, and makes new
40. small intestines: A very long, coiled, tube-like organ that
absorbs the nutrients from food.
41. stimuli: Events or conditions that cause a living thing to react.
42. stomach: A j-shaped sac that stores and further digests food.
43. synapse: The gap between two neurons.
44. tendons: Tough bands of connective tissue that connects the
muscles to the bones.
45. tongue: The muscle that helps push food to the back of the
mouth where it is swallowed.
46. trachea: The windpipe.
47. veins: The blood vessels that carry blood back to the heart.
48. ventricle: The two lower chambers of the heart.
49. villi: Tiny finger-like structures that line the inner wall of the
50. voluntary muscles: Muscles that you can control consciously
