How do organs get their shape?
Abstract. Organ shape depends on the coordination between cell proliferation and the spatial arrangement of cells during development. Much is known about the mechanisms that regulate cell proliferation, but the processes by which the cells are orderly distributed remain unknown.
(OR-gun) A part of the body that performs a specific function. For example, the heart is an organ.
As we saw above, every organ is made up of two or more tissues, groups of similar cells that work together to perform a specific task. Humans—and other large multicellular animals—are made up of four basic tissue types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
The skeletal system provides a definite shape to the body and protection to the internal organs.
During organ growth, the dimensions in a particular axis can be altered in two main ways. First, cells can be rearranged. Second, the orientation of cell divisions can be controlled. Hence, genes that regulate the orientation of mitotic spindles might also play a role in determining organ shape.
Altogether, there are 10 large organs in the body, which include skin, liver, brain, lungs, heart, kidney, spleen, pancreas, thyroid and joints. A few of them are explained in detail below. Skin is the largest external organ of the human body.
The word organ is derived from the Ancient Greek ὄργανον (órganon), a generic term for an instrument or a tool, via the Latin organum, an instrument similar to a portative organ used in ancient Roman circus games. The Greek engineer Ctesibius of Alexandria is credited with inventing the organ in the 3rd century BC.
organ, in biology, a group of tissues in a living organism that have been adapted to perform a specific function. In higher animals, organs are grouped into organ systems; e.g., the esophagus, stomach, and liver are organs of the digestive system.
The human body contains five organs that are considered vital for survival. They are the heart, brain, kidneys, liver, and lungs.

The 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems.
These 11 major organ systems of our human body are the integumentary system (skin), skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems. Following is a brief review of the functions of our 11 human organ systems.
The skin is the body's largest organ.
Generally, cells are round, spherical or elongated. Some cells are long and pointed at both ends. They exhibit a spindle shape.
Usually, the cells are round, elongated or spherical. There are also some cells which are long and pointed on both the ends. Such cells exhibit spindle shape. In some cases, the cells are very long.
Thus, the 'skeleton' gives a shape and structure to our body.
The shape of the body can change when we exert a force on it.
Whether it's the heart, lung or kidneys, sizes of organs differ from person to person, but the organ size from the donor to recipient must be similar to have the best long-term results.
They grow until you're fully grown, which is usually your late teens and early twenties. But it's hard to generalize, considering you have almost eighty organs, which make up many different organ systems.
How many organs are there?
An organ is a group of tissues that has a unique purpose. They perform vital life-supporting functions, like pumping blood or eliminating toxins. Many resources state that there are 79 known organs in the human body. Together, these structures keep us alive and make us who we are.
Blood is considered a type of connective tissue (sometimes). However, an organ is formed of multiple different tissues. Thus, blood is a tissue, not an organ.
The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature.
In music, the organ is a keyboard instrument of one or more pipe divisions or other means for producing tones, each played from its own manual, with the hands, or pedalboard, with the feet.
Although it is one of the most complex of all musical instruments, the organ has the longest and most involved history and the largest and oldest extant repertoire of any instrument in Western music.
