organs
All organs from all other body systems are not part of the gastrointestinal tract. As some examples, these are not involved with digestion: heart, lung, skin, reproductive organs.
The difference between cells, tissues, organs, and body systems are that many cells make tissues, many tissues make organs, and many organs make body systems.
Other sections include cells, plants, invertebrates, and vertebrates. ... in your body and the final level of the progression from cells to tissues to organs and then systems. ... We just explained how organs could be a part of several systems.
The endoderm of the gastrula turns into internal organs such as the liver and pancreas, and into the lining of some systems.
Cell make up tissues,tissues make up organs and organs make up organ systems, and organ systems make a whole organism
The human anatomy is categorized into separate "systems" depending on the type of function each organ or structure performs. For example, the penis is part of the Reproductive System but is also part of the Urinary System because the penis has two distinct functions. The kidneys and urinary bladder are two organs of the Urinary System because they have a similar function. When we view the entire body, with each of its separate organ systems, we can say the entire body is a holistic system which strives to maintain "homeostasis", which is a word that generally means "a normal state". But only with the separate organ systems can the entire body be considered a unit of systems.
Organs in your body are all part of a diffrent system called organ systems. Theres circulitory system, respitory, digestive and skeletal. The heart for example is in the circulitory system.
An organism is a living thing, such as a human or an oak tree. Organ systems make up the organism to achieve the processes it requires. Examples are the respiratory and circulatory systems. Organs are individual parts of the organ systems, e.g. the kidney is part of the excretory system, and the heart is part of the circulatory system. Tissues make up the organs, and are masses of cells of the same type. Muscle tissue makes up part of many organs. Cells are the basic units of life, for instance muscle cells make muscle tissue, and nerve cells make nerve tissue.
