An organ system is made of a group of organs that are working to do a specific job. An organ is made up of a group of tissues working together to do a specific job. Tissues are made of a group of cells that are similar and working together to do a specific job.
A tissue is made of cells of a single type, working together. An example is striated muscle tissue which enables us to perform voluntary movements in the body. Another example is epithelial tissue which lines organs inside the body. The lining of the mouth contains epithelial tissue. An organ is composed of several different types of tissue working together to perform a function. An example of an organ is the heart. Tissues that make up the heart include--blood, nerve, connective, muscle, and epithelial tissues. When these tissues work together, the job of the heart can be performed. The heart is able to pump blood to the lungs and to all the systems of the body, constantly throughout a person's life. However, the heart is only one part of the organ system known as the transport or circulatory system. An organ system is composed of several types of organs working together to carry out a life process, in this case transport. The organs in the transport system include the heart, arteries, capillaries and veins. Organ systems work together to maintain homeostasis within an organism.
The difference between an organ and a tissue is that basically tissues are a group of similar cells that works together . Then a group of tissue that works together would make up an organ. Groups of organ working together later makes up an organ system . This is the main difference between an organ and a tissue.
tissue is made up of no. of cells combined together to perform a specefic work given to them. a group of tissues makes an organ. and diffrent organs performing the difrent activities are wholely known as organ system.
A GROUP OF CELLS MAKE A TISSUE ...A GROUP OF TISSUES MAKE AN ORGAN...AND A GROUP OF ORGANS MAKE AN ORGAN SYSTEM ...AS SIMPLE AS THAT! REMEMBER IT THIS WAY,YOU'LL FIND IT EASIER TO UNDERSTAND AND WILL BE ABLE TO WRITE IN EXAMS..:)
