The body consists of 9 main organ methods, Every made up of a variety of organs and tissues that do the job collectively as being a functional device. The chief constituents and key functions of each method are:
Group of numerous very similar cells (even though occasionally composed of several connected forms) that do the job jointly to accomplish a selected purpose.
Digestive SystemThe digestive program is a gaggle of organs Doing the job alongside one another to convert meals into Vitality and standard nutrients to feed the complete body.
