Explain organ and organ system level.
Answers
An organ system is a group of organs that work together to perform a certain function in an organism's body. Most animals and plants have organs, which are self-contained groups of tissues such as the heart that work together to perform one function. ... The human body has 11 different organ systems.
Required Answer
Organ:
In higher multicellular organisms more than
one type of tissue having related functions are organized together and make a unit, called organ.Different tissues of an organ perform their specific functions and these functions collectively become the functions of that organ.
Example:
For example stomach is an organ specialized for the digestion of proteins and for storing food. Two major types of tissue are present in its structure. Epithelial (glandular). tissue secretes gastric juice for the digestion of proteins. Muscular tissue performs contractions of stomach walls for grinding of food and moving food to posterior end. So two tissues perform their specific functions, which collectively become the function of stomach,

Organ system level:
The next level of organization in multicellular organisms is the organ system level.
Different organs performing related functions are organized together in the form of an organ system. In an organ system, each organ carries out its specific function and the functions of all organs appear as the function of the organ system.
Example:
For example, digestive system is an organ system that carries out the process of digestion. Major organs in its framework are oral cavity, stomach, small intestine, large intestine, liver, and pancreas. All these organs help in the process of digestion.
