Here are the directions for my science homework: Respond to questions a and b as your conclusion from this investigation. Please create a visual model in each response by coming diagrams/graphics with writing - full paragraphs are not required. The of specific organs from different systems must be identified and explained in your response.Please help!!!! Since you can't make a diagram on here, just tell me in order how they work to fuel oxygen and food molecules!!! Oh and also, this was for our pig dissection. So yeah. It's most likely about a pig! PLEASE HELP! Thanks! :)
Well for oxygen, you breath in oxygen and it travels through your trachea into your lungs into your alveolis. In your alveolis, oxygen is exchanged for CO2 with your blood as it passes by in the capillaries. Then it takes the oxygenated blood from the capillary of your alveolis to your pulmonary veins to your left atrium--left ventricle--aorta--vena cava--rest of your body (cells) For food: Mouth--esophagus--stomach--duodenum intestine--Large intestine okay the actual absorption of food (sugar) occurs in the small intestine. These disaccharides were broken down by the pancreas and mouth (amylase). Small intestine has fold which are called villi which have hexose transporters. These sugar transporters bind to the monosaccharides and take then across the cell membrane to the interior of the intestinal cell. Once inside the cell, the sugars move to the other side of the cell, where different hexose transporters deposit them into the capillaries abutting the intestinal cell. From there, sugar is in your blood which carries it to cells that take up the sugar molecules for energy based on the homeostatic glucagon/insulin cycle. I hope this is what you were looking for or atleast helped
