an organ system for its is made up of cells, which interact with one another to serve a function or purpose
It is called the Cellular Level of Organazation and it ranges from (Atoms, Molecuels,Cells, Tissue, Oragans ,Oragan System and Oraganism). There are ten Oragn systems (Digestive, Integumentary,Bone) for examples. An organ system is a group of cells that make up tissue, that make up an organ like the brain or heart. The Brains organ sytem is called the Central Nervous System (CNS), and the heart is apart of the Respiratory System. So the answer to your question is "Yes" an organ system is more complex compared to an organ. The organ system can explain the function of an organ. Whats a stomach without the intestines and the colon together these three organs make up the Digestive System. Organ systems are simply made up of some organ.
cell
Cell combines to form an Organ and Organs comprise the Organ System which makes up an ORGANISM. A lung is comprised of MORE than ONE CELL that does complex functions. A lung is not a cell alone, it is composed of more than one cell. Our lungs is an organ that is composed with cells, we cannot directly say that a lung is a cell. :-)
the hierarchy of organization for biology in descending order is, the biosphere, ecosystem, population, community, organism, organ system, organ, tissue, cell, organelle, and molecule. hope this helps;)
A system carries on more activities than a organ.
Two or more organs are in an organ system. In addition to organs, an organ system can contain other structures that serve the organ(s) and organ system.
The multicellular organism contains two or more cells. They also own an organ system which contains tissues and organs.
they would have more trouble transplanting an organ system because an organ system is composed of more things than just one organ and blood vessels that go to it.
no an organ system has more than one tissue
Skin is a membrane because it keeps that which is within it contained. There was a cell then more cells which made tissues, so there were tissues and more tissues and this made an organ, when more then one organ works together to perform a function it is then a body system.
organelle → cell → tissue → organ → organ system → organism
The level of organization more complex than a system is the organism. The organism is made up of multiple organ systems working together.
