Digestion is the process in which molecules are broken down to be able to go into cells- or in simpler terms in which molecules are made smaller. There are two types of digestion: mechanical digestion and chemical digestion. Mechanical digestion is the physical break down of food. Chemical digestion is when our food is chemically broken down. Digestion is necessary in order to gain energy and nutrients. The digestive system is different in all kinds of animals. Products of digestion ,in humans, is absorbed in the small intestines through small villi, in which nutrients can enter. Our cells help transfer the nutrients in our body. Our nutrients are transported through our blood stream, through our red blood cells. The last destination for these nutrients (mostly glucose), in humans, is the Liver. Glucose is diffused into the liver and is converted to glycogen. Any excess is stored. This is very closely related to the process of cellular respiration. Cellular respiration is the process in which the chemical energy stored in glucose is used to make ATP. ATP is a molecule that stores all energy that comes from what one has digested, also called the energy of life.
Passion Flower Feather Star Diet
A Passion Flower Feather Star's diet consists of plankton, detritus (1), and any easily digested/small sea creatures, for example, very small snails (5). Feather star's obtain their food through their arms. Their arm's have a sticky substance, mucus, covering them. This mucus helps them grab any food that may float around them. Feather star's then push the food towards their mouth to being digestion. They do not have stomachs so they digest their food through their intestines (5).
