Create a flowchart that traces a drop of water from the time it enters the mouth until it is voided in urine of a mammal. You will have to list structures from the digestive, circulatory and excretory systems.
Mouth→(stomach) duodenum →small intestine→large intestine→ water gets absorbed and enters into blood→ and then enters into the body cells
Water gets eliminated by the cells, after that it enters into the blood circulation→ then to the Kidneys→urinary bladder→excrete out via the urethra in the form of urine.
The ingested water is absorbed in the duodenum, the 1st part of the small intestine. The adult duodenum normally soaks up 7 to 8 liters of water into the bloodstream every day, from both solid food and liquids. It has even greater absorptive capacity if called upon; more than 20 liters of water absorbable per day, and this along a stretch of the small intestine only 25 - 35 cm. in length. Further down the alimentary canal, on a typical day, about 1500 ml. of chime, which is mostly water enters the colon (large intestine). Most (~90% or more) of this remaining water is absorbed by the colon, leaving about 100 ml. daily remaining in the stool for excretion.
