The fresh air that was in the air absorbs into your veins in your lung area and then hooks up to a hemoglobin molecule. The hemoglobin molecule carries the oxygen. The blood that was saturated with oxygen inside the lungs then simply travels towards the heart which is pumped out from the body through the aorta. In the event blood actually reaches an area that is certainly low in o2 the hemoglobin molecule emits oxygen.
2 . Trace the way of food from ingestion to defecation. Briefly describe what happens at each stop for the journey. (See figs 18. 11 and fig 14. 13 inside your text for some hints! )
You gnaw your food, after this you swallow. The meals travels through the esophagus, through your esophagus that goes down to your stomach.
