Renal vains
This is when you have a high concentration of solute (ie. Na) in your blood in contrast to a low concentration of water in the blood.
Diffusion, whether of gases or some other substance, is always dependent on a diffusion gradient. Diffusion always occurs from an area of high [H] concentration to an area of low [L] concentration.In the case of the lungs:oxygen moves from a [H] concentration in the lungs/alveoli to a [L] concentration in the bloodcarbon dioxide moves from [H] concentration in the blood to a [L] concentration in the lungs/alveoliWith tissues, the situation is much the same:oxygen moves from a [H] concentration in the blood to a [L] concentration in the tissuescarbon dioxide moves from a [H] concentration in the tissues to a [L] concentration in the blood
Ultra filtration, Absorption and Re absorption
Uremia is the medical term meaning excessive nitrogenous waste in the blood.
Primarily the kidneys produce urine to eliminate nitrogenous wastes. They also play a pivtol role in regulating electrolytes, blood pH and blood pressure.
When a person loses blood plasma, a rise in cellular concentration as well as protein concentration occurs. This is hemoconcentration when this occurs.
Kidneys filter nitrogenous waste from the blood.
Hemoconcentration occurs when there is an increase in the concentration of blood cells as the result of the loss of plasma from the bloodstream. A decrease in volume of plasma and an increase in red blood circulating.

Diastole is the term meaning the period of ventricular relaxation with the lowest blood pressure. The diastolic number is the second or bottom number in the blood pressure reading, and it is always the lowest.
At the level of the capillaries, oxygen will diffuse out of the saturated red blood cells down their concentration gradient into the tissues where their concentration is lowest.
Azotemia or uremia means high blood levels of nitrogenous waste.
Urea is the nitrogenous waste product filtered from the blood and excreted in the form of urine.
Your kidneys filer your blood of nitrogenous wastes. These wastes are then moved to the bladder in the form of urine and expelled.
This is when you have a high concentration of solute (ie. Na) in your blood in contrast to a low concentration of water in the blood.
As it circulates, the oxygen diffuses into the blood via the alveolar wall, this then transfer the oxygen to the red blood cells, as diffusion occurs at this point, oxygen diffuses from a high concentration to a low concentration, so the oxygen diffuses into the blood whereas the CO2 diffuses into the alveoli and then out of the mouth when we expire.
