Amongst them there is the RS. The respiratory system consists of a network of organs and tissues that help us breath. ]]> 2021-04-30 15:34:09 UTC https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1478709186 melaniezheng305 https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1478797360 This systems includes:
◦ Nose and nasal cavity
◦ Sinuses 
◦ Mouth
◦ Pharynx (throat)
◦ Larynx (voice box)
◦ Trachea (windpipe)
◦ Diaphragm
◦ Lungs
◦ Bronchial tubes/bronchi
◦ Bronchioles
◦ Alveoli
◦ Capillaries ]]> 2021-04-30 15:51:10 UTC https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1478797360 melaniezheng305 https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1478804942 1. You inhale air from your nose or mouth, which then travels down to your throat and into the windpipe. From there the air is divided into air passages, also known as the bronchial tubes.

2. From the bronchial tubes the air passes through the lungs which then divided into smaller air passages, known as the bronchioles and end up in the alveoli, little balloon like sacs. *The human body has over 600 million of these*.

3. From the alveoli it goes to the capillaries which are mesh of tiny blood vessels. From here oxygen is transferred to the blood and the cardiovascular system begins where the heart receives the oxygen and then pumps it to the rest of the body tissue and organs. ]]> 2021-04-30 15:52:42 UTC https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1478804942 melaniezheng305 https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1478836040 2021-04-30 15:58:58 UTC https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1478836040 melaniezheng305 https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1478876733 Besides helping you breathe this system also has other functions.
◦ Allows you to talk and to smell
◦ Helps to adjust to your ideal body temperature and humidity level your body needs
◦ Delivers oxygen cells to your body
◦ Removes toxic gases like CO2 when exhaling 
◦ Protects your airways from harmful substances ]]> 2021-04-30 16:07:33 UTC https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1478876733 melaniezheng305 https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1479107048 2021-04-30 16:56:15 UTC https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1479107048 melaniezheng305 https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1480268124 The process of inhalation and exhalation is the way the body brings in oxygen and gets rid of CO2. Everytime you inhale the diaphragm (a large dome-shaped muscle under the lungs) creates something like a vacuum where a rush of air goes into the lungs. When you exhale, the opposite happens and your diaphragm relaxes allowing your lungs to deflate. ]]> 2021-05-01 00:22:23 UTC https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1480268124 melaniezheng305 https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1480279696 2021-05-01 00:33:18 UTC https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1480279696 melaniezheng305 https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1480281733 2021-05-01 00:35:26 UTC https://padlet.com/melaniezheng305/nfkod8sqtuyzqp8y/wish/1480281733
