What is the gradient called that is the driving force for the movement of water and dissolved solutes from the arterial ends of blood capillaries?

The blood pressure in the capillaries at arterial end is about 25 to 30 mm of Mercury. The oncotic pressure of the plasma proteins is about 22 mm of Mercury. So there is net force, which drives out the fluid in the interstitial space. The fluid is sucked back at the venous end of the capillaries by the oncotic pressure of the plasma proteins. It should be called as pressure gradient.

Describe source of lymph and mechanism of lymph transport?
Lymph: fluid within lymphatic vessels 1. Made of water & dissolved substances (that had left blood capillaries by filtration and diffusion) 2.Includes small, dissolved proteins that had also leaked from capillaries Forces that propel lymph through lymphatic vessels: - skeletal muscle contractions - breathing movements - contraction of smooth muscle in walls of lymphatic trunks (movement similar to venous movement)
Contrast the direction of movement of oxygen in lung capillaries and other capillaries in the body?
the direction of movement of oxygen from the air you breathe and to dispose of excess.
A concentration gradient ceases to exist when?
There is no net movement.
Does gradient is very important for mass movement?
yes
The movement of oxygen from the lung into the pulmonary capillaries is by?
diffusion
What defines the movement of material along a concentration gradient through a protein channels?

What is diffusion gradient?
a gradual change in the concentration of solutes in a solution as a function of distance through a solution. 2. the gradual difference in the concentration of solutes in a solution between two regions. In biology, a gradient results from an unequal distribution of ions across the cell membrane. When this happens, solutes move along a concentration gradient. This kind of movement is called diffusion.
Movement of a substance down the substance's concentration gradient?
diffusion
Osmosis is defined as the movement of?
water across a concentration gradient
