Q. No.What is coordination?
| 1. | It is the process through which two or more organs interact and complement the functions of one another |
| 2. | It is the process of serving tissues |
| 3. | It is the process of giving blood and masses to other tissue at the level of structure |
| 4. | It is the ratio of functional and non functional organs |
