parasites areparasite|ˈparəˌsīt|nounan organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense.•derogatorya person who habitually relies on or exploits others and gives nothing in return.Parasites exist in huge variety, including animals, plants, and microorganisms. They may live as ectoparasites on the surface of the host (e.g., arthropods such as ticks, mites, lice, fleas, and many insects infesting plants) or as endoparasites in the gut or tissues (e.g., many kinds of worm), and cause varying degrees of damage or disease to the host.

What Stabilizes the wall of capillaries?
Pericytes stabilize the wall of capillaries.
What are three types of contractile cells in the body?
Myoepithelial Cells,Pericytes,Myofibroblasts
What is a pericyte?
Pericytes consist of contractile cells that interact with the endothelial cells by covering them. The endolethial cell holds capillaries and venules.
What is Hemangioma Pericytoma?
a vascular tumor composed of spindle cells that are held to be derived from pericytes -- called also perithelioma www.virtualtrials.com/dictionary.cfm
What has the author Andrew Bryan Sutton written?
Andrew Bryan Sutton has written: 'The response of endothelial cells and pericytes to transforming growth factor beta'
What has the author Mikhail S Davidov written?
Mikhail S. Davidov has written: 'The neuroendocrine Leydig cells and their stem cell progenitors, the pericytes' -- subject(s): Leydig cells, Stem cells, Paraneurons
What tissues are found in the liver?
Many tissues form blood vessel walls, including endothelium, pericytes, smooth muscle, and fibroblasts.
How thick is a capillary wall?
Capillaries are the smallest of all the blood vessels, they have extremely thin walls - just one cell thick. There are some spider-like cells (called pericytes) dotted along the outer wall of capillaries which help to stabilize them.
What is spindle cell sarcoma?
Spindle Cell Sarcoma (hemangiopericytoma) Hemangiopericytoma a tumor composed of spindle cells with a rich vascular network, which apparently arises from pericytes. Above retrieved from Answers.com Viper1
What is the structure of the capillaries wall?
very thin, often a cell thick
How many types of cells are there in your heart?
There are at least 6-7 different types of cells (myocytes, smooth muscle, pericytes, endothelial cells, fibroblasts, nerve cells, stem cells) in your heart, excluding transient cells that infiltrate from the blood (i.e. macrophages and other immune cells).
What is the blood brain brain barrier?
The blood-brain barrier (BBB) is a diffusion barrier, which impedes influx of most compounds from blood to brain. Three cellular elements of the brain microvasculature compose the BBB-endothelial cells, astrocyte end-feet, and pericytes (PCs). Tight junctions (TJs), present between the cerebral endothelial cells, form a diffusion barrier, which selectively excludes most blood-borne substances from entering the brain. Astrocytic end-feet tightly ensheath the vessel wall and appear to be critical for the induction and maintenance of the TJ barrier, but astrocytes are not believed to have a barrier function in the mammalian brain.
