Lymphatic System

The Lymphatic System

V F Murphy< a> Friday 10th April 2009

Structure, distribution, function The lymphatic system forms a one way flow system towards the heart. Through this system flows lymph, which starts from blind ended capillaries. The capillaries are very permeable, and feature a loose overlap feature, where with the aid of small anchoring filaments the vessel can take large particles and stay open where the external pressure is greater. This causes problems however, as the vessel also carries large particles, such as viruses, pathogens, and cell…

Pancreatic tissue engineering

V F Murphy< a> Tuesday 27th May 2003

Define the design requirements and constraints for an immuno-isolation membrane to encapsulate isolated islets of Langerhans for pancreatic tissue engineering.

The design requirements and constraints must spring from the function of the immuno-isolation membrane. The membrane serves to isolate the islets without exposing them to the immune system, but still permitting them to work with certain other nutrients within the bloodstream.

The function we are concerned with is the detection of g…
