Digestion
Digestion is the process which food is mechanically broken down and chemically converted so cells are able to absorb the nutrients that the food holds. In order to live, all organisms need to obtain nutrients from their environment. There are two types of digestion. There is mechanical digestion and chemical digestion. All unicellular organisms (except for plants) go through mechanical and chemical digestion. Mechanical digestion is the process where food is physically broken down into smaller pieces. In humans the most recognizable form of mechanical digestion is chewing. When humans chew they physically grind food with their teeth so it breaks down into smaller pieces. Other places that mechanical digestion occurs is in the esophagus by peristalsis and the stomach by churning food. These examples are only a few areas where mechanical digestion occurs. Chemical digestion is where food is chemically broken down into smaller pieces by acids and enzymes. In humans chemical digestion first occurs in the mouth where saliva is released and breaks down food even further. The enzyme in saliva that breaks down food is amylase. Once the food reaches the stomach it gets churned (mechanical digestion) and HCI acid and Pepsin break it down even further. After this process the food is now a gruesome thick creamy substance called chyme. The chyme then enters the small intestine where it goes through receptors and villi that line the wall and take out the nutrients with bile an enzyme that dissolves fats. The villi disperse the nutrients into your blood stream where cells accumulate the nutrients. Once your cells have the nutrients, the nutrients go to the mitochondria an another process occurs called cellular respiration. Cellular respiration is the process where oxygen and glucose is converted into ATP, while excess water and carbon dioxide is produced. The formula for cellular respiration is C6H12O6 + 6O2 = ATP + 6CO2 + 6H20 and it is stored in the mitochondria of the cell and is used when ever needed. They way it is used is ATP is made up of 3 phosphates groups. Then 1 phosphate groups breaks off and converts into ADP. To make the ADP back to ATP the cells go through cellular respiration again completing the cycle of cellular respiration.

Pink Dolphin Diet
The Pink Dolphin has an unusual diet compared to most other salt water Dolphins. Pink Dolphins eat crustaceans, over 50 different types of river fish, occasional turtles and other small crabs found on the bottom of the river[1]. Regular salt water Dolphins diet consist of small fish and squids and nothing with a shell or hard exterior. Pink Dolphins hunt by using echolocation or sonar. Echolocation is when a Pink Dolphin send out high-frequency sound pulses from the top of their head. The sound wave travels through the water hits a fish or another organism in the water then bounces back to the Dolphin. When the sound bounces back their long jaw bone catches the sound wave and the Dolphin knows where the fish are. Dolphins use this method of hunting because the rivers they live in are very muddy hence making it hard for them to see its prey.[2]

Pink Dolphins Internal Anatomy
Inside Pink Dolphins long beaks there are approximately 24-34 conical and molar shaped teeth. In the front of the beak are the conical teeth. Conical teeth are used for holding prey the Dolphin catches. In the back of the beak are the molars. The molars help grind food with hard shells or outside such as occasional turtles. When a dolphin first eats an organism it travels through the esophagus where it can go into three compartments. Most organisms such as humans only have one compartment known as the stomach. But when the organism meets the first compartment it churns the food to break it down, this is mechanical digestion and the food is now a thick liquid called chyme that squirts into the second compartment by a sphincter. The second compartment is the main "stomach" where chemical digestion occurs. The walls of the second compartment then shoot out hydrochloric acid which breaks the ph and protein in the food. The third compartment shoots out fat-digesting enzymes, and alkaline fluid which neutralizes the acid juice in the stomach. The chyme then goes through the duodenum where a juice called bile mixes with the chyme. Bile has different proteins, fats, carbohydrates, and salt in it which breaks up the fats in the food making it smaller and easier to digest. The chyme then hits the small intestine goes through and meets the large intestine where the chyme mixes with excess water and is disposed through the anus. The kidneys take all the salt from blood stream re-filters the blood and the salt is mixed with urine to be disposed.
