DO NOW: Name one (1) of the body systems that we have discussed in class and describe its function.

MINI LESSON (I DO): The Circulatory System

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Circulation 

Blood circulates constantly through our entire body. As it passes through our body it picks up nutrients from our food and drops them off to cells that need them. It also picks up oxygen from our lungs and drops it off at cells to be used for energy. The blood then picks up waste carbon dioxide from the cells and drops it off at the lungs for us to breathe back out. 

Blood Vessels 

Blood vessels are tubes throughout our body that carry the blood. There are two main types of blood vessels: arteries and veins. Arteries carry blood from the heart to the rest of the body. Arteries have to be thick and strong as there is more pressure on them from the heart. When you feel your pulse, this is from an artery. Veins carry used blood back to the heart. They don't need to be as thick. 

Multiple Choice

• A and B

Multiple Choice

CFU: Arteries carry blood ______ the heart and veins carry blood ______ the heart.

• to, from

• from, to

• Both carry blood to the heart

• Both carry blood from the heart

The Respiratory System

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels.

Why do we have to breathe?

One of the main things our body needs is energy. When we eat our body digests the food to get complex molecules like glucose (sugar), which it can use for energy. However, food alone isn't enough. The cells also need oxygen to react with the glucose to create the energy. We get the oxygen to our cells with the respiratory system and by breathing. 

Breathing In 

We breathe in using a muscle called the diaphragm. It flattens out making our lungs expand and fill with air. When we breathe in, air gets forced through our nose or mouth, down our windpipe, and into bronchi tubes in our lungs. These bronchi tubes branch out and get smaller and smaller, like the roots or branches of a tree.
