What can diffuse through the intestinal wall?
Nutrients such as glucose, amino acids, and fatty acids can diffuse through the intestinal wall for absorption into the bloodstream. Water and electrolytes can also diffuse through the intestinal wall to maintain fluid and electrolyte balance in the body.
Will O2 diffuse from air to blood or from blood to the alveolar air?
It will be absorbed from the air into your lungs. Then when it reachs the alveolus it will diffuse from the alveolus into the blood capillaries down an oxygen concentration through diffusion where it will combine with the heamoglobin in the Red Blood Cells.
How do monosaccharides exit the intestinal cell wall into the capillaries?
Injested carbohydrates are broken down through saliva and the stomach into smaller fragments called mono saccharides, or simple sugars. These sugars are transported to the absorptive cells in the lining of the stomach, where they are in, exit, then passively diffuse into the adjoining capillaries.
What happens to most of the digested food carried by the capillaries?
the capillaries diffuse the digested food to every cell in the body
Molecules diffuse from capillaries to body cells by moving through the?
veins
What are the two things that diffuse from body cells to capillaries?
Oxygen and carbon dioxide
How does alveoli help two gases diffuse quickly into and out of the blood?
They have capillaries close to their surfaces.
Exchange of nutrients and gases between the blood and tissue cells?
This process occurs through the capillaries. Nutrients and oxygen diffuse from the blood into the tissues, while waste products and carbon dioxide diffuse from the tissues into the blood. This exchange is facilitated by the thin walls of the capillaries and the high surface area for diffusion.
From the maternal capillaries nutrients diffuse into the capillaries of the chorionic villi and go to the fetus via the?
Umbilical cord or if old enough put on a mirror and snort it
What substance sugar or starch is more likely to diffuse through the small intestine and into the blood stream?
Sugars are more likely to diffuse through the small intestine and into the bloodstream compared to starch. This is because sugars, such as glucose and fructose, are simple carbohydrates that can be directly absorbed by the intestinal lining. In contrast, starches are complex carbohydrates that must first be broken down into simpler sugars by enzymes before absorption can occur. As a result, sugars can enter the bloodstream more readily than starches.
What does the alveoli and blood capillaries have in common?
they are both one cell thick to let the gases diffuse
What are blood vessels called that surround the nephron loop?
Renal capillaries, aka the glomerulus, where nitrogenous wastes and excess water in the blood plasma diffuse over to the nephron to be filtered and excreted.
