Heart diagram (labelled/colored) Word wall mini-poster Sept.11, 2018 You need: Clean paper / Pencil Heart diagram (labelled/colored) Word wall mini-poster Warm Up: (on your WARM UP sheet) What are the parts of the blood? I CAN: identify the structures and function of the circulatory system. I CAN: identify the structures and function of the respiratory system.

Be the positive. It takes many “put-ups” to cancel a “put-down.”

The Digestive System The digestive system has 3 main functions: It breaks down food into particles that the body can use. It absorbs nutrients into the blood. It eliminates waste from the body. Mouth Esophagus

The Excretory system Eliminates waste from the body.

What does it do for us? Our circulatory system… Delivers necessary materials (like oxygen and sugar) to the entire body in the blood, Removes waste products from cells, and Helps fight disease by transporting immune cells in the blood.

So, the detailed path of blood in your body would look like this: From Body Right Atrium Right Ventricle To Lungs From Lung Left Atrium Left Ventricle To Body Lung Body

Heart labels Sup. Vena Cava AORTA To LUNGS To LUNGS Left Right atrium From LUNGS From LUNGS Right Ventricle Left Ventricle Inf. Vena Cava

What carries the blood? BLOOD VESSELS are the hollow tubes that carry your blood around your body. There are 3 TYPES: ARTERIES CAPILLARIES VEINS

What is your blood? Red Blood Cells carry oxygen. White blood cells fight disease. Platelets form blood clots to stop you from bleeding too much.

So what happens if you don’t take care of your circulatory system? Not enough good stuff to your body Build up of bad stuff in your body Heart Attack!

What is the RESPIRATORY SYSTEM? - Breathe in and out… What is the RESPIRATORY SYSTEM? The system of the body that deals with BREATHING. It consists of the NOSE, PHARYNX, TRACHEA, BRONCHIAL TUBES, and LUNGS.

What is the FUNCTION of the Respiratory System? - Breathe in and out… What is the FUNCTION of the Respiratory System? To DELIVER OXYGEN to the body. To REMOVE CARBON DIOXIDE from the body.

Why does the body need oxygen? - Breathe in and out… Why does the body need oxygen? The body’s CELLS use OXYGEN to release ENERGY to the body. CELLULAR RESPIRATION is the CHEMICAL REACTION that uses GLUCOSE & OXYGEN to release ENERGY. CARBON DIOXIDE is a WASTE PRODUCT of this chemical reaction.

Which systems work together? - Breathe in and out… Which systems work together? RESPIRATORY SYSTEM gets OXYGEN from the air. DIGESTIVE SYSTEM gets GLUCOSE from food. CIRCULATORY SYSTEM DELIVERS oxygen and glucose to cells. In the cells, respiration uses glucose and oxygen to release ENERGY.

What path does AIR flow? Try it Use the words on your table and work with your elbow partner to put them in order. Raise your hand when you are done.

What path does AIR follow? - Breathe in and out… What path does AIR follow? NOSE PHARYNX TRACHEA BRONCHIAL TUBES LUNGS (alveoli)

What happens in each part? - Breathe in and out… What happens in each part? NOSE – in the nasal cavity, the air is: Warmed, FILTERED, and moistened. (Mucus and nasal hairs keep out dust, pollen and other particles). PHARYNX – air passes through the THROAT when breathing. The EPIGLOTTIS covers the trachea when you SWALLOW to prevent FOOD from entering the trachea when you eat/drink.

What happens in each part? - Breathe in and out… What happens in each part? TRACHEA – is the WINDPIPE that leads to the lungs. It is a TUBE with RINGS OF CARTILAGE. BRONCHIAL TUBES – are the the short tubes that branch off the trachea TO CARRY AIR TO the LUNGS.

What happens in each part? - Breathe in and out… What happens in each part? LUNGS – inside the lungs, the bronchi branch into SMALLER TUBES. At the end of the smallest tubes, are structures called ALVEOLI. ALVEOLI – are AIR SACS, surrounded by CAPILLARIES. This where BLOOD picks up OXYGEN and gets rid of CARBON DIOXIDE.

What happens in the ALVEOLI? - Breathe in and out… What happens in the ALVEOLI? GAS EXCHANGE - Blood from the body enters the lungs. In the alveoli, the blood GETS RID OF CARBON DIOXIDE and PICKS UP OXYGEN before returning to the heart to take oxygen to rest of the body.

How do we BREATHE?

How are BREATHING & SPEAKING related? Air that you BREATHE OUT when you exhale also helps you SPEAK. Your LARYNX is your VOICE BOX which has 2 VOCAL CHORDS that move and produce sound when air passes through the opening between them. Larynx

Let’s make a demo! At your table, you have a bottle, balloons, rubber bands, and straw “thing” Stretch the balloon over the bottom of the bottle…the open area. Secure the balloon with a rubber band. Place the straw “thing” into the bottle and screw the top on. Pinching the balloon that you stretched on the bottle, pull down. What happens to the balloon on the straw “thing”? Why? Note: straw “thing” is really just a straw with a balloon secured to one end of it and the straw then secured through a hole in the bottle top. This would represent the lungs – a tube inward to an inflatable pouch. I tried to make about 8 of these in advance – so students just had to assemble a little.

Are there any questions?
