Oxygen (binded to haemoglobin to form oxyhaemoglobin)
Carbon dioxide (in the form of bicarbonate ions dissolved in the plasma and forming carbaminohaemoglobin with haemoglobin in the red blood cell)
Glucose and amino acids (Digested food substances)
Mineral salts and vitamins
Urea and uric acid
Water
Large Food Molecules in The Small Intestine!
3 or 4
Absorption is the process
Absorption.
Yes.
Starch molecules are too large to pass through the pores of a partially permeable membrane. The size exclusion limit of the membrane restricts the passage of larger molecules like starch while allowing smaller molecules like water to pass through via osmosis.
oxygen from lungs pass to the blood capilleries in which it enter in red blood cells which carry 4 molecules of oxygen by combinig with one molecule of Hb Oxygen from blood transfer to cells where it helps in metabolic reaction and cellular respiration.
The phrase "some molecules pass" best describes the property of selective permeability.
The area where chemicals pass between cells and blood is called the interstitial space. This space contains fluid that surrounds the cells and allows for the exchange of nutrients, waste products, and signaling molecules between the blood and the cells.
The reason why red blood cells don't pass through the dialysis tube is because red blood cells are too large to fit through the pores in the membranes but urea and salt flow through membranes into the sterile solution and are removed.
Yes, protein can be found in the blood of the glomerulus, but normally it should not pass through the filtration barrier into the urine. The glomerulus filters blood, allowing water, electrolytes, and small molecules to pass while retaining larger molecules like proteins in the bloodstream. If proteins are detected in urine, it may indicate a problem with kidney function, such as glomerular damage.
Gases, All small molecules (food, structural materials, minerals); hormones, and antibodies.
