Feb 11 2019 You need Clean paper Pencil
Feb. 11, 2019 You need: • Clean paper / Pencil • Warm up from last week • Any work to be turned in…? (heart WS? ) Warm Up: What are some dangers of not caring for your respiratory system? I CAN: identify the parts and function of the respiratory system and reasons for care.
REVIEW 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.
REVIEW Heart labels Sup. Vena Cava AORTA To LUNGS Right atrium From LUNGS Inf. Vena Cava Right Ventricle Left Atrium Left Ventricle From LUNGS
Turn in… • We turned in the Warm ups from last week – be sure to mark Thursday as “Team meeting with admin” and Friday as “Field trip to NCCU. ” Date should be filled in. • We also turned in the heart diagram (it should be colored in, labeled, and show the path of blood flow).
REVIEW 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! (about 20 minyoutube video linked) Watched Thursday. . .
New notes – (should have been done Thurs/Fri) Respiratory System • Listen and follow along. • Fill in your notes on the worksheet provided.
- 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.
- Breathe in and out… What is the FUNCTION of the System? Respiratory • To DELIVER OXYGEN to the body. • To REMOVE CARBON DIOXIDE from the body.
- 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.
- 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. Ø In the cells, respiration uses glucose and oxygen to release ENERGY.
What path does AIR flow? • Try it • Use the words on your table (green slips) and work with your elbow partner to put them in order. • Raise your hand when you are done. • You should have five slips (bronchial tubes, pharynx, trachea, nose, lungs). • Paper clip them back together (out of order) when the teacher asks you to clean.
- Breathe in and out… What path does AIR follow? • • NOSE PHARYNX TRACHEA BRONCHIAL TUBES • LUNGS (alveoli)
- 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.
- 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 short tubes that branch off the trachea TO CARRY AIR TO the LUNGS.
- 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.
Not on the notes- worksheet, good to read through. Breathe inbut 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 do we BREATHE? • When you breathe, the actions of your DIAPHRAGM and RIBS expand or contract your chest, changing the VOLUME of your lungs. As a result, AIR rushes in or out.
How do we BREATHE? • Inhalation – the DIAPHRAGM (a large dome-shaped muscle at the base of the lungs) contracts and moves DOWN. The rib cage moves UP and OUT. The volume of the lungs INCREASES and air flows IN.
How do we BREATHE? • Exhalation – the DIAPHRAGM relaxes and moves UP. The rib cage relaxes and returns to its ORIGINAL POSITION. The volume of the lungs DECREASES and air is FORCED OUT.
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
