Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart. These systems help each other carry their functions, and the body performs its work.

• Superior vena cava- blood from the head, neck and arms.
• Inferior vena cava- blood from the lower part of the body.

Tricuspid valve will open allowing the blood to enter the right ventricle. Right ventricle contracts while the right atrium relaxes. ]]> 2021-09-21 06:23:58 UTC https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756245540 apstefanierosecea https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756248598 Step 3: right ventricle wiil have high pressure causing the tricuspid valve to close, this closing can be heard as a "lub" sound. Pulmonary arteries that is attached to each lobe of the lungs. ]]> 2021-09-21 06:25:50 UTC https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756248598 apstefanierosecea https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756256738 Step 4: Deoxygenated blood enters the lungs and passes through its capillaries. Oxygen will diffuse from the alveoli to the blood while the carbon dioxide will diffuse from the blood to the alveoli to be released through exhalation. Blood becomes oxygenated blood ad becomes bright red in color. ]]> 2021-09-21 06:30:24 UTC https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756256738 apstefanierosecea https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756259363 Step 5: Oxygenated blood from the lungs passes through the pulmonary veins going to the left atrium. The left atrium will contract allowing the mitral valve to open. ]]> 2021-09-21 06:32:02 UTC https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756259363 apstefanierosecea https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756262295 Step 6: When the mitral valve opens, oxygenated blood will now flow to the left ventricle. The left ventricle contracts and the left atrium relaxes. To prevent backflow of blood the mitral valve will close. This will produce the sound "dib".]]> 2021-09-21 06:33:45 UTC https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756262295 apstefanierosecea https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756265009 Step 7: The left ventricle will contract allowing the oxygenated blood to be pumped to the aorta and leaves the heart. oxygenated blood will be distributed to all parts of the body through the arteris. ]]> 2021-09-21 06:35:29 UTC https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756265009 apstefanierosecea https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756273012 Step 8: Oxygenated blood will pass through the arteries to the capillaries and be defused to the cells. Cells will use the oxygen and will give off carbon dioxide. The blood will become deoxygenated and will pass through the veins back to the heart. ]]> 2021-09-21 06:40:06 UTC https://padlet.com/apallisonmaebalderas/dyxypa265lbhkdne/wish/1756273012
