Answer: 1. Organ system
2. Organ
3. Cell
4. Tissue
Explanation:
1. An organ system is a combination of two or more organs which are responsible for the conduction of a vital function in the body. For example, nose, phyrnx, larynx, and lungs they are responsible for the process of respiration.
2. An organ is a group of specialized tissues that combined and adapted together to perform a specialized function in an organism.
3. A cell is a basic unit of life. It is the small unit which forms the structural basis of the organism. The organisms may vary in complexity depending upon the number of cells and the functions performed by these cells.
4. A tissue is a group of cells. These cells combine together to perform a function that is common to all. The cells in tissues have a common origin.
An ORGAN SYSTEM consists of organs that work together to perform a function, while an ORGAN is a group of tissues that perform a function. A CELL is the basic unit of life, whereas a TISSUE is a group of cells.
- A cell is the basic functional and structural unit of all organisms. All organisms are composed of cells, which derive from an ancestral (preexisting) cell.
- A tissue is a group of cells that perform specific tasks within the organ.
- For example, cardiomyocytes are specialized cells in the heart involved in the generation of the contractile force.
- An organ is a group of tissues that play a specific task in the body.
- For example, the heart is an organ composed of three different tissues (i.e., epicardium, myocardium, and endocardium) that pump blood to all body regions.
- An organs system is a group of organs that are specialized to perform specific functions.
- For example, the circulatory system is an organ system consisting of the heart, arteries, veins, and capillaries that work together to transport oxygen and nutrients to all body cells.
In conclusion, an ORGAN SYSTEM consists of organs that work together to perform a function, while an ORGAN is a group of tissues that perform a function. A CELL is the basic unit of life, whereas a TISSUE is a group of cells.
