explain how the difference in diameter is responsible for the process that occurs in the malpighian body

Malpighian body is made up of the glomerulus and the Bowman's Capsule. The glomerulus is a network of capillaries that receives blood from the afferent arteriole and gives it further to the efferent arteriole. From the glomerulus, the component of blood diffuse into the Bowman's Capsule through the endothelium and basement membrane of the glomerulus and the epithelium of Bowman's Capsule.

The blood comes into the glomerulus through which it is diffused into the Bowman's capsule. Only the smaller solute molecules and water is allowed to pass through the membranes while the blood cells are retained within the glomerulus. Hence, the Malpighian Body allows the filtration of blood so that the waste can be separated from the blood. The filtrate further moves to tubules where fine reabsorption and secretion takes place. Both the kidneys produce approximately 180 liters of filtrate every day.

The difference in diameter is responsible for the process that occurs in the malpighian body as - it forms some obstruction to blood flow, which results in higher pressure in the glomerular cavity.

Malpighian Body is a structure located in Nephron in the urinary system that helps in ultrafiltration of blood. It consists of a glomerulus and its surrounding Bowman's capsule.

There are two main arteries in the Malpighian body of blood vessels

one entered for filtration, called afferent arteriole.
one leaving the structure after filtration called efferent arteriole.

Differences in diameter provide for the increased blood pressure in the glomerulus for ultrafiltration.

The afferent arteriole has a larger diameter, which leads to more blood would flow into the efferent arteriole, which is of a smaller diameter due to this causes more blood pressure or hydrostatic pressure in the glomerulus.

Thus, the correct answer is - it forms some obstruction to blood flow, which results in higher pressure in the glomerular cavity.
