The cluster of capillaries that forms a glomerulus arises from an afferent arteriole. After passing through the glomerular capillaries, blood (minus any filtered fluid) enters an efferent arteriole whose diameter is smaller than that of the afferent vessel. This is instead of entering a venule, the usual circulatory route. The efferent arteriole resists blood flow to some extent, which backs up blood into the glomerulus, increasing pressure in the glomerular capillary.

The lamina densa is a component of the glomerular basement membrane (GBM) in the renal corpuscle. It provides structural support and acts as a filtration barrier, preventing the passage of large molecules like proteins from the blood into the glomerular filtrate. It also helps maintain the integrity and function of the renal corpuscle by separating the glomerular endothelial cells and podocytes.

Homeostasis.
Homestatasis is a relatively constant internal physical and chemical conditions that organisms maintain. It is a branch of biology in science.

Homeostasis is the term that describes an organism's ability to regulate and maintain a relatively constant internal temperature, regardless of external conditions.
DNA helps maintain homeostasis by the proteins and lipids associated with DNA and RNA. These proteins and fats regulated both hormones and growth.

The 'hoplites' of Archaic Age Greece were armed as spearmen, and therefore relatively easy to equip and maintain.
