B	to increase intestinal absorption.
C	to inhibit diffusion of nitrogenous wastes.
D	to create adequate oncotic pressure.

Explanation:

Detailed explanation-1: -The heart pumps blood filled with oxygen through all parts of your body, including the kidneys. The kidneys clean the blood, removing waste products and extra water. Without the kidneys, your blood would have too much waste and water.

Detailed explanation-2: -It’s the muscle at the centre of your circulation system, pumping blood around your body as your heart beats. This blood sends oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.

Detailed explanation-3: -Each day, your heart beats around 100, 000 times. This continuously pumps about five litres (eight pints) of blood around your body through a network of blood vessels called your circulatory system. This blood delivers oxygen and nutrients to all parts of your body to help your organs and muscles work properly.

Detailed explanation-4: -Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine.
