Organ (anatomy)

In biology, tissue is a cellular organisational level between cells and a complete organ.
An organ' is a group of Tissues with similar functions.

Histology

histologicalhistologichistologist
The study of human and animal tissues is known as histology or, in connection with disease, histopathology also not forgetting to add, archeology.
also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues.

Histopathology

histopathologicalhistopathologichistopathologist
The study of human and animal tissues is known as histology or, in connection with disease, histopathology also not forgetting to add, archeology.
Histopathology (compound of three Greek words: ἱστός histos "tissue", πάθος pathos "suffering", and -λογία -logia "study of") refers to the microscopic examination of tissue in order to study the manifestations of disease.

Plant anatomy

anatomyanatomy of plantsphytotomy
For plants, the discipline is called plant anatomy. In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue.
Plant anatomy is now frequently investigated at the cellular level, and often involves the sectioning of tissues and microscopy.

Staining

stainstainedstains
The classical tools for studying tissues are the paraffin block in which tissue is embedded and then sectioned, the histological stain, and the optical microscope.
Stains may be used to define biological tissues (highlighting, for example, muscle fibers or connective tissue), cell populations (classifying different blood cells), or organelles within individual cells.

Connective tissue

fibrous tissuefibrous connective tissueconnective
Animal tissues are grouped into four basic types: connective, muscle, nervous, and epithelial.
Connective tissue (CT) is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue.

Nervous tissue

Animal tissues are grouped into four basic types: connective, muscle, nervous, and epithelial.
Nervous tissue, also called neural tissue or nerve tissue, is the main tissue component of the nervous system.

Epithelium

Animal tissues are grouped into four basic types: connective, muscle, nervous, and epithelial.
Epithelium is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue.

Blood vessel

vascularblood vesselsintravascular
The epithelium in all animals is derived from the ectoderm and endoderm, with a small contribution from the mesoderm, forming the endothelium, a specialized type of epithelium that composes the vasculature.
There are five types of blood vessels: the arteries, which carry the blood away from the heart; the arterioles; the capillaries, where the exchange of water and chemicals between the blood and the tissues occurs; the venules; and the veins, which carry blood from the capillaries back towards the heart.

Skin

This tissue covers all organismal surfaces that come in contact with the external environment such as the skin, the airways, and the digestive tract.
In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments and internal organs.

Biology

biologicalBiological Sciencesbiologist
In biology, tissue is a cellular organisational level between cells and a complete organ.
Developmental biology, originated from embryology, studies the genetic control of cell growth, cellular differentiation, and "cellular morphogenesis," which is the process that progressively gives rise to tissues, organs, and anatomy.

Cell (biology)

cellcellscellular
In biology, tissue is a cellular organisational level between cells and a complete organ.
This leads to growth in multicellular organisms (the growth of tissue) and to procreation (vegetative reproduction) in unicellular organisms.

Human body

Muscle cells form the active contractile tissue of the body known as muscle tissue or muscular tissue.
It is composed of many different types of cells that together create tissues and subsequently organ systems.

Endoderm

The epithelium in all animals is derived from the ectoderm and endoderm, with a small contribution from the mesoderm, forming the endothelium, a specialized type of epithelium that composes the vasculature.
The following chart shows the tissues produced by the endoderm.

Extracellular matrix

ECMmatrixextracellular matrices
A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function.
Plant cells are tessellated to form tissues.

Secretion

secretedsecretory pathwaysecrete
It serves functions of protection, secretion, and absorption, and is separated from other tissues below by a basal lamina.
Tissues in humans that produce secretions include the gastrointestinal tract which secretes digestive enzymes and gastric acid, the lung which secretes surfactants, and sebaceous glands which secrete sebum to lubricate the skin and hair.

Vascular tissue

vascularvascular systemplant tissue
In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue.
Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants.

Xylem

Xylem serves as a chief conducting tissue of vascular plants.
Xylem is one of the two types of transport tissue in vascular plants, phloem being the other.

Cellular differentiation

Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.

Meristem

A meristem is the tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place.

Xerophyte

Spindle shape fiber also contained into this cell to support them and known as prosenchyma, succulent parenchyma also noted.In xerophytes, parenchyma tissues store water.
Other species are able to survive long periods of extreme dryness or desiccation of their tissues, during which their metabolic activity may effectively shut down.

Phloem

Phloem (pronunciation: ) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed.

The term was introduced in anatomy by Marie François Xavier Bichat in 1801.
Although he worked without a microscope, Bichat distinguished 21 types of elementary tissues from which the organs of the human body are composed.
