Why is the blood pressure lower in lung capillaries than body capillaries?
Because if blood pressure in lung capillaries was as high as it is in body capillaries, the hydrostatic pressure caused by this blood pressure would force blood plasma out of the capillaries into intracellular spaces (as is done in body capillaries) or into the alveoli. This would reduce the efficiency of gas exchange.
Why do capillaries have spaces between endothelial cells?
Capillaries have spaces between endothelial cells to allow for the exchange of gases, nutrients, and waste products between the blood and surrounding tissues. This structure, known as intercellular clefts, facilitates the transfer of substances through the capillary wall.
What are the spaces between the ribs called?
Intercostal spaces
What causes interstitial tissue fluid?
Interstitial fluid (or tissue fluid) is a solution that surrounds the cells of animals. It is the main component of the extracellular fluid, it includes plasma and transcellular fluid. The interstitial fluid is found in the interstitial spaces, also known as the tissue spaces.
What are the spaces called in between a pile of soil?
pore spaces
Certain capillaries in the brain including the choroid plexus do not have spaces between the cells effectively creating a?
blood-brain barrier (!)
What are the spaces between rocks and soil called?
The spaces between rocks and soil are called pore spaces or interstitial spaces. These spaces are important for water infiltration, aeration, and root penetration in the soil.
What are the spaces in a comb called?
the spaces between the teeth of a comb are called umpernaters :) that's their scientific name.
What are the spaces in between particles called?
cementation
What causes the fluid part of the blood to be forced through the walls of the capillaries into the space inside the capsule?
This process, known as filtration, is driven by the pressure difference between the blood inside the capillaries (hydrostatic pressure) and the fluid in the tissue spaces outside the capillaries (osmotic pressure). The hydrostatic pressure pushes fluid out of the capillaries, while the osmotic pressure in the tissue spaces helps to prevent excessive fluid loss by drawing fluid back in.
What is the placental barrier made up of?
Chorionic Villi with Fetal capillaries Intervillous Spaces Decidua basalis with maternal capillaries
What are the spaces between the topographic lines called?
The spaces between the topographic lines are called contour intervals. They represent the difference in elevation between each line on a topographic map.
