What else can I help you with?
Water passes from the tissue fluids into the blood capillaries mainly because?
lymph blood has a higher protein concentration than the tissue fluids
Oxygen diffuses into the capillaries of the lungs because there is?
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
What makes oxygen pass into the capillaries that surround these sacs?
Diffusion. O2 moves from an area of higher concentration to a lower concentration.
What does the oxygen pass out from the bloodstream?
Oxygen diffuses from red blood cells in the bloodstream into body tissues through capillaries. It moves from areas of higher concentration in the blood to areas of lower concentration in the tissues, where it is used for cellular respiration.
Is gluten higher in level in protein flour?
Yes, gluten concentration would be higher in high protein flower because the gluten is the main protein in flour.
Would the concentration of a diluted protein shake with an absorbance value of 70mg ml be darker than a protein concentration of 15mg ml?
Yes, the diluted protein shake with an absorbance value of 70mg/ml would appear darker than the protein concentration of 15mg/ml. Higher absorbance values indicate a higher concentration of solute present in the solution, leading to a darker appearance.
How do water molecules move through the cell membrane during omosis?
With a specific channel protein called aquaporins.
Why does oxygen diffuse in and carbon dioxide diffuse out?
In the alveoli, oxygen diffuses into the blood that the capillaries carry due to a concentration gradient that exists there as oxygen conc is higher in the alveolar sacs than in the blood capillaries. Similarly carbon dioxide diffuses out of the blood capillaries into the alveolar sacs down the concentration gradient. The constant flow of blood is there to ensure this concentration gradient is established at all times.
How can blood diffuse into and out of capillaries?
Blood diffuses into and out of capillaries through a process called diffusion, which occurs due to the concentration gradients of oxygen, carbon dioxide, nutrients, and waste products. As blood flows through capillaries, oxygen and nutrients move from areas of higher concentration in the blood to lower concentrations in surrounding tissues, while carbon dioxide and waste products move in the opposite direction. The thin walls of capillaries, composed of a single layer of endothelial cells, facilitate this exchange. Additionally, factors such as blood pressure and osmotic pressure also play a role in regulating the movement of fluids and solutes across the capillary walls.
What is the driving force that pulls interstitial fluid back into the capillaries?
The driving force that pulls interstitial fluid back into the capillaries is primarily osmotic pressure created by proteins in the blood, such as albumin. This osmotic pressure causes water to move from areas of lower solute concentration (interstitial fluid) to areas of higher solute concentration (capillaries), helping to maintain fluid balance in the body.
In materials move from an area of higher concentration to an area of lower concentration through a cell membrane.?
Through the process of mitosis.
What is the pathway of movement for substances traveling across a capillary wall?
Capillaries have very thin walls which are semi-permeable.
