Solution and Explanation

The average diameter of a Malpighian body (also known as a renal corpuscle or renal glomerulus) in humans is approximately 150-250 micrometers (μm).

The Malpighian body, or renal corpuscle, is a key structure in the kidney that plays a crucial role in the filtration of blood. It consists of two primary components:

  • Glomerulus: A network of capillaries where blood is filtered.
  • Bowman's capsule: The surrounding structure that collects the filtrate from the glomerulus.

Average Size: The average diameter of a renal corpuscle in humans ranges from approximately 150 to 250 micrometers (μm). However, the size can vary based on several factors such as:

  • Age: As a person ages, the size and structure of the renal corpuscle may undergo slight changes.
  • Health Conditions: Certain diseases, such as kidney conditions or hypertension, may cause changes in the size of the renal corpuscle.
  • Species Differences: The diameter of the renal corpuscle may differ between species, reflecting variations in kidney function across organisms.

Significance: The size of the renal corpuscle is important for understanding its efficiency in filtering blood. Changes in the size can affect kidney function and may indicate potential health issues.

Summary: The diameter of the Malpighian body in humans is typically between 150-250 μm, but variations can occur based on age, health status, and species-specific differences.

Excretory products and their elimination

The physiological process of the elimination of metabolic waste from the body is called excretion. The excretory products comprise amino acids, carbon dioxide, urea, uric acid, water, and ammonia. Some of the Molluscs and Echinoderms excrete waste products from the body in the form of amino acids. Ammonia is the foremost excretory product in animals, it is derived from the proteins exists in the food we eat.
