### cell:

Endocrine cell
* appear to be very important in the local regulation of the laryngeal mucosa.
* are the cells that secrete hormones.
* produce hormones that travel through the blood to reach all parts of the body.

### cell:

Endothelial cell
* -These cells form the lining of the blood vessels.
* are cells that line internal cavities including blood vessels and glands
  - fairly flat and pancake-shaped
  - important targets for a variety of treatment strategies
  - responsible for corneal clarity and appropriate hydration of the cornea
  - vital in preventing the clogging and hardening of the arteries
* can release NO to dilate local blood vessels or endothelin to constrict vessels.
* grow and divide toward organ-forming regions secreting angiogenesis factors.
* have a cobble stone appearance
  - many complex functions essential to health
* internalize monoclonal antibody to angiotensin -converting enzyme.
* line the vessel wall and form a tight overlapping barrier to macromolecules.
* make new blood vessels in a process called angiogenesis.
* possess carrier systems to actively transport certain substances into the brain.
* prevent accumulation of lipid hydroperoxides in low-density lipoprotein.
* produce buds off existing blood vessel near the tumor.
* seem to be more affected than neutrophils.
* swelling is another histological feature of capillaritis.
* vary in their organization of TJs.

Erythroblast
* appear mainly during the early fetal period.
* are a source of angiogenic factors.

### cell:

Erythrocyte
* also contain substantial amounts of the enzyme carbonic anhydrase
  - lack all other subcellular organelles such as mitochondria
* antigens and their normal and abnormal immunology.
* are also the carriers of the properties that define blood groups
  - ingested
  - more numerous than leukocytes
  - the red blood cells in a hummingbird's blood
  - very flexible and change shape when flowing through capillaries
* can move passively to the extravascular space during emigration by diapedesis.
* contain no DNA, however, having lost their nuclei during maturation.
* fill the lumen of the arteriole.
* have an increased passive permeability to sodium ions.
* includes cell membranes
  - chromosomes
  - corpi
  - cytoskeletons
  - lobes
  - plasma membranes
  - sections
  - vacuoles
* lack nuclei and mitochondria, critical elements in the machinery of apoptosis.
* maintain regular shape and size.
* possess an intrinsic barrier to nitric oxide consumption.
* protect cultured endothelial cells from neutrophil-mediated damage.
* pyruvate kinase deficiency resulting in congenital non-spherocytic hemolytic anemia.
* synthesize large amounts of hemoglobin, which carries oxygen.
* transport oxygen and carbon dioxide between the lungs and the tissues of the body.

### cell | erythrocyte:

Mature erythrocyte
* are released into the capillaries
  - visible in most pictures
* lack a nucleus.

Eucaryotic cell
* Some eucaryotic cells are very small.
* understand the signals preceding the synthetase genes of octopine and nopaline.

### cell:

Eukaryote cell
* have many different internal membranes and structures , called organelles.
+ Eukaryote, Structure: Cell biology :: Protista :: Taxonomy :: Evolutionary biology
  * Eukaryotic cells are usually much bigger than prokaryotes. They can be up to 10 times bigger. Eukaryote cells have many different internal membranes and structures, called organelles. They also have a cytoskeleton. The cytoskeleton is made up of microtubules and microfilaments. Those parts are very important in the cell's shape. Eukaryotic DNA is put in bundles called chromosomes, which are separated by a microtubular spindle during cell division. Most eukaryotes have some sort of sexual reproduction through fertilisation, which prokaryotes do not use.
