Transcript of What are the Similarities and Differences Between Lungs and Gills?

Lungs VS. Gills Our Question:
How are Lungs Different from Gills? By Devin,
Nora, & Tammy
Period 1 Lungs In the lung when a 12 year old breaths the oxygen goes into the blood really well and after your 12 the oxygen doesnt go into your blood quite as well. CO2 doen't change as much. The diffusion would be greatest in a young teenager. The more heavier your body mass is, the more area your lungs take up. Alveoli are little air sacks located in your lung. Gills
Your lungs keep your body’s cells full of oxygen and gets rid of the carbon dioxide waste. When you breathe in the air, the blood leaves the lungs and gets carried to the heart, and then pumps through your body to provide oxygen to the cells of your tissues and organs. The outer wall of the vessel acts a semi-permeable membrane across which osmosis can take place
While lungs breathe in oxygen from the air, gills get oxygen from water. Gills are external while lungs are internal. Since fish live in water it’s obvious their lungs are structured different and work differently than human lungs. Gills are located on each side of a fish’s body just behind the head. Gills are thin and leafy, and each gill has 2 rows of a thread-like gill filaments covered with a thin membrane. The capillaries are small blood vessels which supplies blood to the gills. CO2 waste is taken out and back into the water. Lungs and gills are very important for the human and fish. Without it, we wouldn’t be able to breath, or have blood pumped to our heart. Osmosis is the diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane. A fluid can be liquid or gas. So, what the fish releases after it breathes in the water, that solution is a higher concentration than water. CO2 is produced and transferred to the blood, and it carries the CO2 back to your lungs and removes it as you exhale. It’s an important repetition. You breathe without even thinking of breathing. the tiny little air sacs are held in high pressure. The concentration inside the sacs is greater than the concentration of the vessels around the sacs.
