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.
What else can I help you with?
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.
Is the movement of substances against their concentration gradient an active or passive process?
The movement of substances against their concentration gradient is an active process.
How long does movement occur across a concentration gradient?
Movement across a concentration gradient occurs until equilibrium is reached, where the concentration of a substance is the same on both sides of the gradient. The rate of movement depends on factors such as the size of the gradient, temperature, and properties of the substance.
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.
The movement of oxygen from the lung into the pulmonary capillaries is by?
diffusion
Does gradient is very important for mass movement?
Yes, gradient is an important factor in mass movement as it influences the speed and type of movement. Steeper gradients can increase the likelihood of mass movement events such as landslides, while gentler gradients may still allow movement but at a slower pace. Understanding gradient helps assess the risk of mass movement in a particular area.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
Is the movement of molecules across a membrane down the concentration gradient a passive or active process?
The movement of molecules across a membrane down the concentration gradient is a passive process.
What is the principle force that causes movement of fluid from tissues into capillaries?
The principle force that causes movement of fluid from tissues into capillaries is oncotic pressure. This pressure is generated by the presence of proteins in the blood that draw fluid back into the capillaries by osmosis.
What is the movement of substances from the capillaries into the renal tubules?
Tubular secretion
Movement of leukocytes from capillaries to damaged tissue is called?
Diapedesis
What defines the movement of material along a concentration gradient through a protein channels?
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.
