Lesson 2Pages 6 – 7What Makes Your Body Live and Grow

The Building Blocks

Define: Cells: the basic building blocks of living tissue. Tissues: groups of cells working together (ex.

Muscle tissue) Organs: collections of two or more muscles

working together (ex. Heart) Systems: several organs working together to

perform a major function (ex. Digestive system)

Cell

Draw a picture of a body cell and label the nucleus, cytoplasm and cell membrane.

Definition and Function:• Nucleus: It is the brain of the cell. It controls

everything the cell does.• Cytoplasm: It is a fluid – like substance that

holds all the parts of the cell together and provides nourishment to the cell.

• Cell Membrane: It is the outside skin of the cell and protects the cell from everything outside.

Structure and Function of the Digestive System

Mouth: The teeth grind up the food . The tongue detects “good’ and “bad” flavors and helps move food around the mouth and down the throat. Saliva (spit) helps with chewing and swallowing and starts digestion.

Esophagus: A tube-like structure that moves food from the mouth to the stomach.

Stomach: A bag- like structure where chemicals break the food down to be used by the body for energy. It has three jobs:

• to store the food you've eaten• to break down the food into a liquidy mixture• to slowly empty that liquidy mixture into the small intestine

Structure and Function of the Digestive System (cont.)

Small intestine: It is a tube - like structure that breaks down the food mixture even more so your body can absorb all the vitamins, minerals, proteins, carbohydrates, and fats.

Large Intestine: It is a tube – like structure where nutrients are absorbed. The parts of food that cannot be used are passed out of the body.

Structure and Function of the Digestive System (cont.)

Pancreas: The pancreas makes juices that help the body digest fats, starches and protein.

Liver: A juice from the liver called bile helps to absorb fats into the bloodstream.

Gallbladder: The gallbladder serves as a warehouse for bile, storing it until the body needs it.

Structure and Function of the Digestive System (cont.)

Colon: The part of the large intestine called the colon is where the body gets its last chance to absorb the water and some minerals into the blood.

Rectum: The very last stop on the digestive tract. The solid waste stays here until you are ready to go to the bathroom.

Anus: When you go to the bathroom, you get rid of the solid waste by pushing it through the anus.

Diabetes (p. 20)

Diabetes is a disease that affects how the body uses glucose, a sugar that is the body's main source of fuel. Like a CD player needs batteries, your body needs glucose to keep running.

If someone has diabetes, the body either can't make insulin (this is called type 1 diabetes) or the insulin doesn't work in the body like it should (this is called type 2 diabetes). The glucose can't get into the cells normally, so the blood sugar level gets too high. Lots of sugar in the blood makes people sick if they don't get treatment.

How can diabetes can be controlled?

Kids who have type 1 diabetes can help themselves stay healthy by taking these four very important steps:

• taking insulin• eating a healthy diet and following a

meal plan• checking blood sugar levels• being active by playing and getting

exercise

Kids who have type 2 diabetes can help themselves stay healthy by taking these three very important steps:

• getting to a healthy weight (by eating healthy and getting exercise)

• taking medicine if the doctor feels it's necessary

• checking blood sugar levels often
