Considering a polar molecule in a plasma medium, the electron-molecule dipole potential is modified to incorporate the screening effect of the plasma, which is characterised by the inverse Debye-shielding-length ina -1 0. Born differential cross-sections (DCS) for the rotational excitations of target molecules like HCl, H2O and HCN are calculated for various low incident electron energies as well as for various values of . The effect of plasma screening is not only to reduce the DCS but also to alter the angular distribution. In general the DCS near the forward direction are considerably reduced. The present Born results are not expected to be reliable for strongly screening plasmas.
Large Food Molecules in The Small Intestine!
Small, non-polar molecules like oxygen, carbon dioxide, and water can passively diffuse through cell membranes and be absorbed into the blood. Lipid-soluble molecules and small uncharged molecules can also passively cross cell membranes to enter the bloodstream.
Oxygen is primarily transported in the blood bound to hemoglobin molecules within red blood cells. This allows for efficient delivery of oxygen to tissues throughout the body. Additionally, a small amount of oxygen is also dissolved directly in the plasma of the blood.
Red blood cells release oxygen molecules in the capillaries of body tissues where they are needed for cellular respiration. The oxygen diffuses from the red blood cells into the surrounding tissues due to the concentration gradient between the red blood cells and the tissues.
Reabsorption is the process by which molecules move from the proximal convoluted tubule into the blood.
The small, soluble molecules get through the wall of the small intestine and into the blood

From digestion to inter-cellular space through to blood vessels, in which the blood then brings the molecules to rest of the body

One hemoglobin molecule in a red blood cell can bind up to four oxygen molecules. Therefore, one blood cell could potentially carry up to four oxygen molecules at a time.
If human blood is put in salt water, the water molecules in the human blood will lead to the lower concentration of water molecules. This process is called diffusion- water molecules going from high concentration to low concentration.

Blood vessels do not carry air. Blood vessels carry blood, and this blood can carry dissolved gas molecules.
