no an organ system has more than one tissue
The levels or organization are: cells -->tissues--->organs--->organ systems--->organism. The heart is an organ of the organ system called the cardiovascular system. This includes the heart, veins and arteries and blood.
A tissue (not the kind you sneeze into) is a similar group of cells that perform the same function. a tissue. and a group of tissues working together is called an organ. and a group of organs working together is called an organ system.
it is an organ
Connective tissue does not belong to any one system, rather, it refers to one of the four types of tissue that make up nearly every organ in the human body. For example, the connective tissue found in ligaments and tendons are a part of the musculoskeletal system, but connective tissue also surrounds the stomach, anchoring the epidermal tissue of the stomach lining to the body.
Organs. But one organ may contain several different types of tissue with different functions.
A fact about organs is that you need cells and tissue to make up organs. because cells make up tissue and tissue makes up organs and organs make up organ system and an organ system makes up organism which are how humans are made up by.
An organ is a group of tissue that works together to perform similar functions.
It is an organ. A tongue is an organ because a group of tissues makes up an organ. A tongue is more than a tissue, so it must be an organ. Each type of tissue in the tongue performs an essential task to help the tongue function properly.
The pancreas is an organ. It is one of the unique organs that have both endocrine and exocrine functions.
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.
Cells make up tissues, which make up organs, which make up organ systems.
