Freshwater crocodile the same weight. This allows them to live for a half a year without eating. After the food goes down the throat, it is met in the gizzard by sand and rocks -these elements help break apart the bones, horns, hooves, hide, and flesh. This more broken-down material then enters the hydrochloric acid of the stomach. The hearts of other reptiles are designed to contain three sections including two atriums and ventricle. The right atrium, which collects the returned de-oxygenated blood and the left atrium which collects the oxygenated blood collected from pulmonary arteries of the lung, takes the blood
Extracellular digestion down outside the cell either mechanically or with acid by special molecules called enzymes. Then the newly broken down nutrients can be absorbed by the cells nearby. Humans use extracellular digestion when they eat. Their teeth grind the food, enzymes and acid in the stomach liquefy it, and additional enzymes in the small intestine break the food down into parts their cells can use. Although fungi do not have a digestive tract like humans, they still use extracellular digestion. Fungi and other decomposers utilize nutrients derived from breaking down the substrate they grow on. Another example of extracellular digestion being
