A group of organ systems is called what ... Please Help?

there are many different body systems that contain different organs you need to give us information.

If you're referring to a group of organs, then that is a "system". whereas a group of systems would be a "Body".

It's an organism

tissues make up an organ, organs make up a system, and systems make up an organism.

The Body.

Brain, spinal cord and peripheral nerves.
Heart, blood vessels and blood.
Skeletal muscles and smooth muscles.
Bones, cartilage, tendons and ligaments.
Nose, trachea and lungs.
Mouth, esophagus, stomach, small and large intestines.
Kidneys, ureters, bladder and urethra.
Female: ovaries, oviducts, uterus, vagina and mammary glands.
Male: testes, seminal vesicles and penis.
Lymph, lymph nodes and vessels, white blood cells, T- and B- cells.

An organ system is an organ system. Do you want the biological hierarchy where it goes from a molecule to a cell to a tissue to an organ to an organ system to an organism( just one of the species) to a population(the entire species in the community) to the community(everything that breathes air) to finally the ecosystem which is all things biotic and abiotic? is that what you want?
