When a person is starving the body compensates for the low intake levels of calories by breaking down muscle. The metabolism increases breaking down high levels of protein found in the muscle. When the liver digests the protein it produces urea as a waste product. The more protein digested the higher the urea levels- so, the longer a person is starved the higher the urea levels will be.
When a person is starving, their body breaks down protein for energy, leading to an increase in urea production as a byproduct of protein metabolism. Urea is then released into the blood and its concentration rises due to the increased breakdown of proteins for energy in the absence of sufficient food intake.
Acidemia (or acidaemia) is a medical condition marked by an abnormally high concentration of hydrogen ions in a person's blood.
oxygen
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.
hypercapnia
Hyperglycemia
diffusion: particles move from a high concentration to a low concentration
Blood sugar test.
Hyperglycemia.
Oxygen diffuses into the blood in the lungs and binds to the hemoglobin since the oxygen concentration is high and the carbon dioxide concentration is low. The blood is pumped to the body. The hemoglobin releases the oxygen to the tissues because here, the concentration of oxygen is low and that of carbon dioxide is high.
the blood plasma carries waste products, including urea.
High Blood Pressure
The kidney is a filter system for the blood. If the concentration of a substance is too high (i.e. there are drugs in the blood), then the kidney filters all of that out of the blood to form urine.
