What is homeostasis? The
bodies maintenance of a stable internal environment
The 11 human body systems are as follows: (Match each system to the correct function)
1. Nervous system* _E_
2. Respiratory system*__A_
3. Excretory system _G__
4. Muscular system __B__
5. Endocrine system __F_
6. Immune system _H__
7. Reproductive system __I_
8. Circulatory system*_D__
9. Digestive system*_C__
10. Skeletal system*_J__
11. Integumentary system ___K__
A. Absorbs oxygen
B. Moves bones
C. Breaks down food
D. Pumps blood
E. Sends and receives electrical signals
F. Regulates body function
G. Gets rid of waste
H. Body’s defense against illness
I. Produces reproductive cells
J. Provides a frame and support
K. Protects underlying tissues
2. Name the 8 organs that make up the digestive system and describe their function.
3. What are the digestive organs that make up the digestive track? (in order)
___Mouth, Esophagus, Stomach, Small Intestine, Large Intestine___
5. Label the following diagram with the correct digestive organs.
4. Name the five senses the human body has.
Sight, Touch, Taste, Smell, Hearing
5. The nervous system is made up of two systems. What are they?
Central Nervous System CNS
Peripheral Nervous System PNS
6. What two organs make up the CNS?
Brain and Spinal Cord
7. What is the overall function of the CNS? The control center of the body
8. What organs makes up the PNS? Nerves
9. What is the overall function of the PNS? Carries information
10. What are the three parts of the human brain and what do they control?
Cerebrum  Controls memory, problem solving, thinking & feeling. It also controls movement
Cerebellum  Controls coordination and balance
Brain Stem  Controls automatic functions such as breathing, heart rate and digestion
11. What are the 8 organs (in order) that make up the respiratory system and what are there functions?
Nose -- Entry and exit point for air
Pharynx--Passage way for both air and food (back of throat)
Epiglottis -- Skin flap that covers the trachea when we swallow
Larynx-- "Voicebox" - Helps you speak using vocal chords
Trachea--"Windpipe" Connects your pharynx to your lungs
Lungs -- 2 large organs in the chest that hold oxygen
Diaphragm -- Muscles that cause you to breath
Bronchial Tubes--Give oxygen to the blood
12. What is the major muscle of the circulatory system? Heart
13. How many chambers does the human heart have? Four
14. Label the chambers of a human heart.
15. What are the three types of blood vessels and what are their functions?
16. What are the three types of blood cells and what is their function?
17. Pretend that you are a red blood cell traveling through the heart. Describe the journey you go on
everyday. Include the following vocabulary. (Bone marrow, heart, oxygen, veins, arteries, capillaries, left
atria, right atria, left ventricle, right ventricle, aorta, pulmonary artery, pulmonary vein, vena cava)
Once I am made in the bone marrow and I enter the heart through the vena cava. I am then sent to the right
atrium and then flow down to the right ventricle. From there I am shot out of the heart into the lungs
through the pulmonary artery where I pick up oxygen. Once I am done I enter back into the heart through
the pulmonary vein. I then enter the left atrium which sends me down to the left ventricle.When I am ready
I get shot back out of the heart through the aorta so I can travel to the organs to deliver oxygen.
18. What are six reasons why bones are so important? Structure, support, protection, make red blood
cells, white blood cells and store minerals
19. How many bones do we have in our adult bodies? 206
20. How many bones do we have when we are born?
300
21. Label the skeleton with the correct bones. (Don’t use your notes to see how much you know, when
you get stuck take your notes out to finish.)
