Respiratory and Circulatory System by [AP-STUDENT] Princess Asiana Macalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4 en-us 2022-09-14 02:40:56 UTC 2022-09-14 03:26:37 UTC hello@padlet.com How the lungs work apprincessasianamacalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295537301 Your lungs are on each side of your heart, inside your chest cavity. They are the main organs of the respiratory system. The right lung is divided into three lobes (sections), and the left lung is divided into two lobes. Your left lung is slightly smaller than your right lung, since your heart takes up some space on the left side. When you breathe in, air enters your airways and travels down into the air sacs, or alveoli, in your lungs. This is where gas exchange takes place. ]]> 2022-09-14 02:52:35 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295537301 apprincessasianamacalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295541241 The circulatory system, which is made up of the heart and blood vessels, supports the respiratory system by bringing blood to and from the lungs. The circulatory system helps deliver nutrients and oxygen from the lungs to tissues and organs throughout the body. It also helps remove carbon dioxide and waste products. Other body systems that work with the respiratory system include the nervous system, lymphatic system, and immune system. ]]> 2022-09-14 02:55:30 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295541241 Airways apprincessasianamacalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295542345 The airways are pipes that carry oxygen-rich air to the alveoli in your lungs. They also carry the waste gas carbon dioxide out of your lungs. The airways include these body parts: 

  • Mouth 
  • Nose and linked air passages called the nasal cavity and Sinus 
  • Larynx (voice box) 
  • Trachea (windpipe) 
  • Tubes called bronchial tubes, or bronchi, and their branches 
  • Smaller tubes called bronchioles that branch off of the bronchial tubes

The air then travels past your voice box and down your windpipe. Rings of tough tissue, called cartilage, acts as a support to keep the bronchial tubes open. 

Inside your lungs, the bronchial tubes branch into thousands of thinner tubes called bronchioles. The bronchioles end in clusters of tiny air sacs called alveoli.

Normally, your alveoli are elastic, meaning that their size and shape can change easily. Alveoli are able to easily expand and contract because their insides are coated with a substance called surfactant. Surfactant reduces the work it takes to breathe by helping the lungs inflate more easily when you breathe in. It also prevents the lungs from collapsing when you breathe out. 

Each of these alveoli is made up of a mesh of tiny blood vessels called capillaries. The capillaries connect to a network of arteries and veins that move blood through your body.

The trachea, bronchi, and bronchioles transport air into and out of the lungs. The pulmonary arteries and veins link to the heart and transport blood into and out of the lungs. These systems work together to carry out their functions, and the body does its work.]]> 2022-09-14 02:58:14 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295545078 Blood low in oxygen flows through the lungs apprincessasianamacalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295545124 The pulmonary artery and its branches deliver blood to the capillaries that surround the alveoli. This blood is rich in carbon dioxide and low in oxygen.]]> 2022-09-14 02:58:15 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295545124 Respiratory and Circulatory System https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295545477 The respiratory and circulatory systems work together in that the respiratory system introduces oxygen to the body and transfers it into the blood stream while the circulatory system transports the oxygenated blood to the other organs.]]> 2022-09-14 02:58:32 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295545477 Oxygen flows into your blood apprincessasianamacalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295546626 Carbon dioxide moves from the blood into the air inside the alveoli. At the same time, oxygen moves from the air into the blood in the capillaries. ]]> 2022-09-14 02:59:22 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295546626 The pleura apprincessasianamacalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295547325 The lungs are surrounded by the pleura, a membrane with two layers. The space between these two layers is called the pleural cavity. A slippery liquid called pleural fluid acts as a lubricant to reduce friction during breathing. ]]> 2022-09-14 02:59:54 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295547325 Circulatory System Summary apprincessasianamacalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295578553 The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.]]> 2022-09-14 03:22:59 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295578553 What are the 7 steps of the circulatory system? apprincessasianamacalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295580320 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) aorta –> 14) body.]]> 2022-09-14 03:24:31 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295580320 What are the 5 major parts of the circulatory system? apprincessasianamacalindong https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295582874 The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells]]> 2022-09-14 03:26:37 UTC https://padlet.com/apprincessasianamacalindong/meicrsq8iwoac7d4/wish/2295582874
