Lymphatic Fluid Pressures

In resting tissues after general anesthesia, the fluid pressures in initial lymphatics are close to zero and tend to be similar to the fluid pressure measured in the interstitial space. There are currently no direct measurements of fluid pressure in pumping initial lymphatics. In contractile lymphatics, the fluid pressures rises during each contraction. The pressure may also rise from one lymphangion to the next if there is an outflow resistance in proximal segments of the lymphatics. Plasma oncotic pressures are lower in lymphatic fluid compared with blood plasma.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
