Organs within a system may be related in any number of ways, but relationships of function are most commonly used.
The internal organs collectively are often called viscera, the plural of the rarely-used term viscus.
Common animal (including human) organs include the heart, lungs, brain, eye, stomach, spleen, bones, pancreas, thyroid, kidneys, liver, intestines, skin (the largest human organ), uterus, and bladder.
The vegetative organs are essential for maintaining the life of a plant (they do the vegetative, vital functions, like photosynthesis), while the reproductive are essential in the reproduction.
Not only animals, but also plants have tissues and organs, with three fundamental plant organs being the roots, stems, and leaves, and an example of tissue being vascular tissue and ground tissue.
Usually in an organ, there is a main tissue and sporadic tissues.
Animal organs inside the body are often referred to as internal organs.
At a lower level of organization an organ is an aggregation of several tissues that interact to perform a specific function, such as the heart pumping blood or the stomach digesting food.
In biology, an organ (Latin: organum, "instrument, tool") is a group of tissues that perform a specific function or group of functions.
Vegetative plant organs are root, stem and leaf, while reproductive organs are flower, seed, and fruit.
The main tissue is the one that is unique for the specific organ.
Organs, exemplified by such diverse components as brain, eyes, and liver, are one of several levels of organization in living organisms.
The functions of organ systems often share significant overlap.
A tissue, in turn, is an aggregation of interconnected, morphologically, and functionally similar cells, and associated intercellular matter, that together perform one or more specific functions within an organism.
The body, on the other hand, supports the individual cell, tissue, organ, and organ system by providing access to food, oxygen, and shelter, and by disposing of waste materials.
Our body contains 11 organ systems which include:Integumentary.Muscular.Skeletal.Nervous.Circulatory.Lymphatic.Respiratory.Endocrine.More items...
While your heart is a vital organ, the brain and of course the nervous system that attaches to your brain make up the most critical organ system in the human body. The human nervous system is responsible for coordinating every movement or action your body takes.Aug 6, 2013
What Are Human Skeletal System Organs?Bones. The most important organ of the skeletal system is the bones. ... Ligaments and Joints. Another important component, i.e. the ligaments are made of fibrous collagen tissue that attaches one bone to another bone. ... Cartilage.
The Heart. The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body. It usually beats from 60 to 100 times per minute, but can go much faster when it needs to.
The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. The skin is only a few millimeters thick yet is by far the largest organ in the body.
