• The term "glomerular capsule" is used specifically in human anatomy and physiology, particularly in the context of the renal (kidney) system. It is a technical term.
• It is often discussed in relation to the process of blood filtration and urine formation.

Examples

• Noun:
  • The filtrate from the blood passes from the glomerulus into the space within the glomerular capsule.
  • The glomerular capsule is also known as Bowman's capsule.

Advanced Usage

• Histological description: In microscopic anatomy, the glomerular capsule is described as having an inner visceral layer (composed of podocytes) and an outer parietal layer.
  • The visceral layer of the glomerular capsule is intimately associated with the glomerular capillaries.
