### body part | tissue:

Different tissue
* Most different tissue serves functions.
* are grouped together to form larger functional units, called organs.
* are in turn grouped together to form functional units, called organs
* can tolerate different supersaturation ratios.
* carry different risks of infectivity.
* have a different constellations of hormone receptors.
* have different kinds of cells
* make up an organ, like a lung.
* use different cofactors.
* working together make up an organ.
+ Cell differentiation: Genetics :: Cell biology :: Developmental biology
  * In developmental biology, 'cellular differentiation' is the process by which a less specialized cell becomes a more specialized cell type. Different tissues have different kinds of cells.

Diseased tissue
* become brittle as they dry out.
* becomes black and brittle and contains an abundance of black spore pustules.
* is usually dark gray to brown in color
  - watery, soft, black and deteriorates rapidly
* turns brown to black and dries out in the field or, more commonly, in storage.

Eardrum
* Most eardrums are covered by skin.
* Some eardrums are part of ears
  - heads
* are body parts
  - membranes
  - solid objects
  - sunken into cavities on sides of head
* includes corpi.
* is animal tissue

Elastic tissue
* encompasses the endothelium and basement membrane.
* holds the cushions in place.
* is absent in the angiofibromas
  - connective tissue

Endoderm
* gives rise to internal organs, among others
  - the gut, digestive organs and lungs
* is animal tissue

### body part | tissue | endoderm:

Embryonic endoderm
* is formed by the process of gastrulation.
* lines two tubes within the body.

Endometrial tissue
* is shed each month during menstruation.
* occurs naturally in the endometrium a layer of tissue lining the uterus.

Endometrium
* Some endometriums are part of uteruses
  - wombs
  - facilitate embryo development
* are mucous membranes.
* is another word for the lining of the uterus
  - the Latin name given to the tissue that lines the uterus
* is the lining layer of the uterus which sloughs off with each menstruation
  - technical word used to represent the uterine lining

Epidermal tissue
* contains a waxy water-impermeable coat called the cuticle.
* forms the outermost layer of the leaf.

### body part | tissue:

Epithelium
* Any epithelium can be simple or stratified.
* Epithelia also form the ducts that connect the glands to the surface.
* Epithelia are avascular
  - composed almost entirely of cells bound closely together by cell junctions
  - two-dimensional sheets that subdivide the animal body into different compartments
  - cover the outside of the body and line the spaces and tubes within the body
* Epithelia have a number of important characters
  - an enormous capacity for growth and repair
  - perform a number of important functions throughout the body
* Some epithelia are pseudostratified.
* Some epitheliums contain mucuses
  - have functions
* Some epitheliums lead to infertility
  - male infertility.
  * ' is one of the four main types of tissue in the body of animals. It is made up of one or more layers of cells. Epithelium is found on the surface of organs and many other parts of the body. The main function of epithelium is moving fluids into or out of an organ or body part. It can also help protect organs and sense things. There are many different types of epithelium that do different things in the body, including the excretory system
* are tissue.
* contain receptors.
* continues vacuolar degeneration and replacement.
* includes cell membranes
  - cytoplasm
  - nuclei
  - plasma membranes
  - sections
  - vacuoles
* is always very thin indeed
  - hyperplastic with goblet cell or squamous metaplasia
  - one of four basic tissue types in the body from which all organs are constructed
  - required for bladder mesenchyme to differentiate into bladder smooth muscle
* is the top layer of skin
  - type of tissue that covers all free body surfaces
