Human Biology
(Comparing Systems)

Humans are highly developed organisms with various organ systems that are adapted for performing life sustaining functions. Each organ system works with other organ systems in the total activity of the body. As humans, we learn about our bodies, and the needs and the things that make for successful living. The human body is very difficult to understand. Students learn about the different parts of their bodies by looking at hands-on models. They compare and contrast the different models with their own bodies. Students will examine in detail their 5 senses, as well as their circulatory and skeletal systems. Comparing and charting human growth will allow students to investigate their own body growth patterns. Students will learn the function of organs as well as how the organs form systems and how these systems interact.

Slide 1.  Human Biology

·       The human body has a well-tuned machine that allows us to live

·       The skeleton protects the organs

·       The organs work together to make humans breathe, think, move, and talk.

Slide 2.  What is the difference?

·       Appendages help movement, and  many times you can live without them

·       Organs are protected by skeleton (especially the core)

·       Organs work together in systems like circulation or respiratory

·       Organs are vital as they work together

Slide 3.  Organs of the Upper Torso

·       The majority of organs are protected by ribs, sternum and scapula

·       The organs are snugly inside our body and overlap

·       There would be capillary and veins that go through specific organs

Slide 4.  Systems of the Human Body

·       Human systems work together to allow us to breath and live

·       Although we are taught them as separate they interact to make a healthy person

·       The circulatory system helps to physically connect, while the brain coordinates the interactions

Slide 5.  Skeletal System

·       Protects soft parts including organs and tissues

·       Bones have specific functions from making red blood cells to support

·       Bones are made of calcium phosphate and are porous so vein and arteries can go through

Slide 6   Integumentary System

·       This system is the skin, which is the largest organ of the body.

·       It physically protects the inside of our body

·       Helps to regulate heat through pores

Slide 7.  Nervous System

·       ntral nervous system is controlled by brain

·       Nerves transmit signals much like wires transfer electricity

·       Includes organs of the senses

Slide 8.   Excretory System

·       Body functions produce waste that needs to be removed

·       Includes the ability of solid waste and liquid waste

Slide 9.    Circulatory System 

·       Includes blood, blood vessels, heart and lymph node

·       Transports nutrients that body needs from water to salts

·       Also transports diseases throughout the body

Slide 10.   Respiratory System

·       This system converts air into oxygen that can be used by the body

·       Includes lungs and associated parts

·       Removes carbon dioxide waste from system

Slide 11.  Digestive System

·       Converts food that we eat into energy that our body needs to live

·       Includes teeth to stomach to intestines

·       Aids in removing material that our body cannot convert

Slide 12.  Muscular System

·       Muscles, tendons and ligaments are attached to bone structure

·       Provides the ability to strength to move

·       Provides pathways for nerves to signal to brain

Slide 13.  Endocrine System

·       Glands produce hormones

·       Hormones help regulate activities of the body from respiration to growth

·       Too much of one hormone can make a body off-balance

 Slide 14.    Reproductive System

·       Produces off-spring

·       In women, this system includes the ovaries, the fallopian tubes, the uterus, the cervix, and the vagina.

·       In men, it includes the prostate, the testes, and the penis.

Slide 15.  Test your body parts 

·       Move body parts over to the torso and if you cannot move the part, you have found the correct location

·       This can be used as a good reviews of the organs and the systems they represent
