Glomerular filtration of a person, who has been starving for a long time, has increased by 20%. The most likely cause of filtration changes in the given conditions is:

Answer options

1. Increase of renal plasma flow
2. Decrease of blood plasma oncotic pressure
3. Increase of filtration factor
4. Increase of systemic blood pressure
5. Increase of renal filter permeability

Explanation

Glomerular filtration of a person, who has been starving for a long time, has increased by 20%. The most likely cause of filtration changes in the given conditions is:Starvation leads to a use up of carbohydrates, fats, and proteins. Protein deficiency leads to a reduction of substances like albumin (heavy molecules) that are responsible for keeping blood plasma oncotic pressure normal, and lack of these heavy molecules will make filtration faster.
