a tissue organ is an organ containing tissue
A tissue is an organ!
Cells are the basic functional units of living things. A groups of cells together forms a tissue. A group of tissues together forms an organ.
Parenchyma is the functional part of an organ (while stroma is the supporting tissue). Echogenicity means ability to produce an echo. So parenchymal echogenicity means the ability of the functional part of an organ to produce an echo (for ultrasound examination for example).
Cells are the basic functional units of living things. A groups of cells together forms a tissue. A group of tissues together forms an organ.
A thing or event that evokes a specific functional reaction in an organ or tissue: "areas of the brain which respond to auditory stimuli".
Cell is a structural and functional unit of an organism. When two or more cells join together we get a tissue. Two or more similar tissue fuse to form a organ. Different organs function together to make a organ system.
Its a tissue organ
according to McGraw-Hill, an organ is more complex, learned from my anatomy homework
tissue- a group of like cells organ- like tissues organ system- organs with related function (cell-> tissue -> organ -> organ system)
An organism is made of organ systems. An organ system is made of organs. An organ is made of tissue. Tissue is made of cells.
