digestive system
The digestive system is responsible for producing enzymes that aid in breaking down substances for absorption. These enzymes help to break down food into smaller molecules that can be absorbed by the body for growth and repair.
Digestion
In the body, various organs and systems are responsible for synthesizing and breaking down substances. The liver plays a crucial role in metabolizing nutrients, detoxifying harmful substances, and producing essential proteins. Enzymes, which are biological catalysts, facilitate these processes by speeding up chemical reactions necessary for digestion and metabolism. Additionally, the immune system helps to destroy pathogens and foreign substances, maintaining the body's internal balance.
The liver is primarily responsible for breaking down and destroying substances in the body. It filters the blood and detoxifies harmful substances, such as alcohol and medications, through various metabolic processes.
The digestive system is responsible for breaking down food into nutrients that can be absorbed by cells through the process of digestion. Nutrients are absorbed into the bloodstream from the small intestine and transported to cells throughout the body for energy, growth, and repair.
The stomach belongs to the digestive system of the body. It is responsible for breaking down food into smaller molecules that can be absorbed by the body to provide nutrients and energy.
When substances change state, energy is either absorbed or released. During melting and boiling, energy is absorbed to break the intermolecular forces holding the substance together, while during freezing and condensation, energy is released as these forces are formed. This energy change is due to the breaking or forming of bonds between molecules.
Absorbed nutrients from ingested food passes through the wall of the intestines into blood vessels, which take them throughout the body. The liver, the main organ involved in digestion, is responsible for breaking up, digesting and absorbing fats, and for detoxifying blood.
Enzymes are responsible for breaking down macromolecules in plants. Different enzymes target specific types of macromolecules, such as carbohydrates, proteins, and lipids, breaking them down into smaller units that can be absorbed and utilized by the plant cells.
The digestive system is responsible for breaking down food into smaller molecules that can be absorbed by the body. This process occurs in the stomach and intestines, where nutrients are absorbed into the bloodstream for use by the body.
The enzyme responsible for breaking down starch is called amylase.
The process of breaking down food in the body is called digestion. It begins in the mouth with chewing and mixing food with saliva, which contains enzymes to start breaking down carbohydrates. From there, the food travels through the esophagus to the stomach where it is further broken down by stomach acid and enzymes. Finally, in the small intestine, nutrients are absorbed into the bloodstream for the body to use.
