An organ is a group of tissues with similar functions. Plant life and animal life rely on many organs that coexist in organ systems. A given organ's tissues can be broadly categorized as parenchyma, the tissue peculiar to the organ and that does the organ's specialized job, and stroma, the tissues with supportive, structural, connective, or ancillary functions. For example, in a gland, the tissue that makes the hormones is the parenchyma, whereas the stroma includes the nerves that innervate the

The organ repertoire is considered to be the largest and oldest repertory of all musical instruments. Because of the organ's prominence in worship in Western Europe from the Middle Ages on, a significant portion of organ repertoire is sacred in nature.

An organ is a self-contained group of tissues that performs a specific function in the body. The heart, liver, and stomach are examples of organs in humans. The word organ comes from the Latin organum, which means “instrument”. This in turn comes from the Greek word ὄργανον (órganon), which refers to a musical instrument or “organ of the body”. Organs are found in most animals and plants.
All animals except for less specialized ones like those in the phylum Porifera (sea sponges) have specialized tissues grouped into organs. The human body has 78 different organs. The largest organ is the skin, while the smallest organ is the pineal gland, which produces the hormone melatonin. Some organs are necessary for survival; these are called vital organs. Humans have five vital organs that they cannot live without: the brain, heart, liver, kidneys, and lungs. (A person can live with on...
There are four different levels of organization in multicellular organisms, and organs make up one of these levels. From simplest to complex, an organism is made up of cells, tissues, organs, and organ systems. Cells make up the most basic level of organization; the cell is the building block of a living organism. This is followed by tissues. Tissues are groups of cells that work together and have a similar structure and function. The four types of tissues in the human body are muscle, epithe...
The body’s organs are grouped into organ systems based on the functions they perform. Humans have 11 different organ systems. Here are all of the organ systems with some examples of organs found in each system:This image depicts parts of the circulatory system, including the heart, arteries, and veins:
1. Tissue – a specialized group of cells that look similar and perform a specific function; groups of similar tissues make up organs. 2. Organ system – a group of organs that works together to carry out a certain function. Humans have 11 organ systems. 3. Vestigial organ – an organ that has evolutionarily lost its original function over time, and presently has little or no function in an organism. The appendix has been widely believed to be vestigial throughout history, although it does have...
