In geomorphology, a drainage system is the pattern formed by the streams, rivers, and lakes in a particular watershed.
In a dendritic system there is one main river (like the trunk of a tree), which is joined and formed by many smaller tributary rivers.
Dendritic systems form in V-shaped valleys; as a result, the rock types must be impervious and non-porous.

 Drainage Patterns
Drainage patterns or nets are classified on the basis of their form and texture.
Drainage channels develop where surface runoff is enhanced and earth materials provide the least resistance to erosion.
Fewer drainage channels will develop where the surface is flat and the soil infiltration is high because the water will soak into the surface.

 immunology - system organs III
It is a drainage system taking away excess tissue fluid.
At its simplest the lymphatic system is used to drain excess fluids from organs and tissue.
The lymphatic system has also been utilized by the immune system as a communication and transport network for lymphocytes and antigen presenting cells culminating in regional repositories of immune cells called lymph nodes.

 Dendritic Drainage Pattern, Yemen
These filigree patterns are termed "dendritic drainages" because of their similarity to the way in which trees branch out into progressively finer twigs.
Runoff from the coastal mountains carved the dendritic drainage pattern, which was then "fossilized" when the climate became more arid.

Dendritic drainage systems are the most common form of drainage system in the world.
As rivers flow across the landscape, they generally increase in size, merging with other rivers.
The network of rivers thus formed is a drainage system and is often dendritic, but may adopt other patterns depending on the regional topography and underlying geology.

 Kansas School Naturalist: Stream Ecology
The quality of the water is impacted by the dominating geology of its drainage as well as the surrounding land use.
If one were to view a river drainage basin from above, it would become apparent that the many drainage channels within the basin form a dendritic pattern in which smaller streams join to form progressively larger streams as one moves downstream.
This flow pattern is often revealed along a relatively straight reach of a stream during periods of low discharge by the appearance of sand or gravel bars seemingly evenly spaced and alternating from side to side of the channel.

Drainage patterns often reveal much about the geology of a region, and an important characteristic of drainage pattern is drainage density.
A river exhibiting transverse drainage across a structural feature that would normally impede its flow because the river predates the structure and kept cutting downward as the structure was uplifted around it.
A river exhibiting transverse drainage across a structural feature that would normally impede its flow because the feature was at some point buried beneath the surface on which the river developed; as the feature became exposed, the river kept cutting through it.

After centuries of playing second fiddle to the blood system, our lymphatic circulation is coming into its own as a key player in diseases ranging from cancer to asthma.
Once dismissed as a mere drainage network, the body's 'second circulation' system (see Graphic, below) is emerging as a crucial player in numerous diseases from cancer to asthma, and as a vital part of the normal immune system.
As a result of these discoveries, researchers are trying to intervene in its activities, for example to reduce the spread of tumours, to boost the efficiency of vaccines, or to treat the painful and disfiguring swelling known as lymphoedema.

 Geology of Mars } Hydro
On the Martian highlands there are many channels and valleys that have similar characteristics as the dendritic (or "treelike" pattern of branches and twigs seen in deciduous trees) drainage systems on Earth.
One problem with this scenario is that it is not consistent with many observed channels that do not possess a dendritic structure.
For example, unlike the drainage system on Earth, some Martian channels were isolated and others had large areas between branches that were not dissected.

 T11D-12 High-Resolution Multibeam Survey of the Insular Shelf and Slope of Windward and Southern O   (Site not responding. Last check: 2007-10-28)
The windward slope is characterized by several large dendritic drainage systems composed of slope channels merging into canyons.
The presence of these large drainage networks may reflect erosion and transport processes that followed the large landslide that removed much of the Koolau Range; they also reflect the high sediment yield from the windward basins of the island.
The southern margin is largely blanketed by large volumes of sediment, possibly reflecting long-term drainage from the Koolau and Waianae Ranges through the southern coastal plain.
