What am I made of?
Inside your body is a very busy place. The many complex processes need energy. To convert energy into a form you can use requires transport highways to take nutrients to where they are needed and to carry wastes away. Different parts of your body work together and rely on each other to accomplish all these tasks. So what do we look like on the inside? How does everything work together so we can live our lives?
Our Amazing Body!!!

5.1) What do I look like on the inside?
5.2) Why are we made up of organ systems?
5.3) The Respiratory System
The main function of our respiratory system is to take oxygen out of the air that we breathe in and remove carbon dioxide when we breathe out. All our cells need oxygen for survival, growth and repair. Task 1) Pluck Dissection Task 2) Complete Respiratory System worksheet Task 3) How do we breathe? a) create the lung model (either using a single or 2 balloons) b) use the lung model to demonstrate how we breathe Task 4) Measure your own lung capacity Task 5) The Cancerous Chemicals in Smoke |
Task 1) Pluck Dissection

A) The Heart
Interesting facts regarding the heart are: 1) It pumps between 5L to 30L of blood each minute 2) It beats around 90 - 120 times per min for teenagers 3) The "thump - thump" sound that you hear is the four valves of the heart closing to pump the blood through the heart |

Extension Task) The Liver
The liver is the largest solid organ in our body. It’s about 8 inches (20 cm) wide, 6.5 inches (17 cm) long and 4.5 inches (12 cm) thick and weighs approximately 3.5 pounds (1.6 kilograms).
You’ll find your liver mostly under your ribs in the upper right part of your abdomen, just below your diaphragm.
The liver has two large lobes; a large right lobe and a smaller left lobe.
The liver has various functions:
Trouble is; the liver also stores all the toxins that our body cannot break down.
You see the liver is broken into three zones, each with a specific function. The blood enters the first zone, travels to the second and third zone then leaves the liver - with each zone being susceptible to its own illnesses.
Amazingly, the liver can regenerating itself, however today with the consistent abuse from our fast paced lifestyle our liver is paying a hefty price.

The liver has various functions:
- It makes and secretes bile to help your body absorb fats and fat-soluble vitamins (A, D, E and K)
- It metabolizes and stores carbohydrates, fats, sugars, vitamins (and other nutrients obtained from the foods we eat) for energy and brain function.
- It breaks down harmful chemicals (bilirubin and ammonia) produced by the body and keeps the body regulated and healthy.
- It manufactures proteins to help maintain blood purity and proper flow.
- It breaks down hormones, detoxifies water and removes drugs, alcohol and environmental toxins
- And it filters waste products from your blood.
Trouble is; the liver also stores all the toxins that our body cannot break down.
