What is the difference between organ and tissue

In animals, there are four different types of tissues: connective, muscle, nervous and epithelial. Organs on the other hand, are structures made up of two or more tissues organized to carry out a particular function.

For example, the heart contains muscle tissue that contracts to pump blood, fibrous tissue that make up the heart valves and special cells that maintain the rate and rhythm of heartbeats. A tissue is a collection of similar cells with similar functions and structures plus the extracellular materials found in-between cells. In contrast, an organ comprises of two or more tissues with one or more functions. Examples of tissues include epithelial tissue, connective tissue, muscular tissue, nerve tissue and ground tissue.

On the other hand, examples of organs include stomach, skin, Brain, penis, heart, intestine, lungs and kidneys. Vascular tissue is involved in transporting water and nutrients throughout the plant body. Ground tissue is involved in photosynthesis and storage of food. An organ is a part of an organism, which performs a set of unique functions in the body. An organ is an incorporation of several types of tissue.

There are five main organs in the animal body, which performs vital functions for the survival of an animal. They are brain, heart, lungs, liver, and kidney.

The brain is a component of the central nervous system of an animal, which coordinate body functions depending on the internal and external stimuli. Heart is the pump of the circulatory system of an animal, which transports both oxygen and nutrients to the cells in the body. Lungs serve as an interface that allows the exchange of respiratory gases between the blood and external environment.

Within the lungs, the blood is saturated with oxygen while carbon dioxide is removed from the blood. Liver serves as the main storage organ in the animal body. It stores glucose as glycogen. Kidney is the main excretory organ in the body, allowing the removal of metabolic wastes and the excess fluid from the circulation. Organs in the animal body are organized into organ systems. The primary organs in plants are stem, root, and leaves.

Flowers, seeds, and spores are considered as reproductive organs in plants. The structures in a flower are shown in figure 2. Tissue: Tissue is any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.

Organ: An organ is a part of an organism, typically self-contained and has a specific vital function in the body. Tissue: A tissue is composed of similar types of cells. The tissue is capable of performing the simple task while organs are known for operating the complex one. Though the size of the organ is greater than the tissue and requires more energy to perform any function.

Being the primary part of every life, the cell varies in their complexities from one organism to other, and this makes every species diverge. The whole biology is studied under two important categories, which are unicellular and multicellular. Unicellular are the single-celled organisms like protozoans, while multicellular is the organisms having two or numerous cells.

We humans and other mammals having the complexed cellular structure with the higher level of multicellularity. Due to which we need a proper organization of the cells to get our body and its internal part work accordingly. So our body also has some levels of systems or configuration according to which it works.

Cells, tissues, organs, and organs systems are part of this system only; these systems work for the body just to maintain the legitimate health. In this article, we will be going through the differences between two of the levels of the human body which are tissue and organs with a brief description.

Basis for Comparison Tissue Organ Meaning Tissues are evenly distributed structures in the body, performing the specific function. These are found in plants and animals, made up of similar cells and function specifically.

Organs are the hollow structure, made up of tissues, and organised to work precisely for the body in animals as well as in plants. Made up of The same type of cells. The same type of tissues. Repairing process If there is some damage in tissue, they can be repaired by regeneration and fibrosis. As tissues make organs, so repair in tissue, will result in repair of the organ. Function Numerous and similar cells make tissue, and this tissue forms organs. They have the certain unique function in the body.

Different organs work for different purpose like breathing, pumping blood, digestion, etc. Examples Nerve tissue, muscles tissue, connective tissue, epithelial tissue.

Stomach, lungs, heart, intestine, bladder, brain, kidney, etc. When the specific and similar type of cells are grouped or organized together constitute the tissue.

These tissues are assigned to perform the specific function. With the invention of the electron microscope, it is observed that the cells present within the tissues shows the morphological similarities and so can be said that they have the common embryonic origin too.
