Blood leaves the glomerulus through the ______ after filtration has occurred.

A. Calyx, nephron, collecting duct, urinary bladder, renal pelvis, ureter, urethra: Sequence is wrong -filtrate is formed in nephron, flows into collecting duct, then into calyx → renal pelvis → ureter → bladder → urethra.
B. Nephron, collecting duct, calyx, renal pelvis, ureter, urinary bladder, urethra: Urine forms in nephron → drains into collecting duct → minor/major calyces → renal pelvis → ureter → urinary bladder → urethra for elimination.
C. Nephron, renal pelvis, collecting duct, calyx, urinary bladder, urethra, ureter:Renal pelvis and calyx order is swapped relative to collecting duct; ureter/bladder order is wrong.
D. Collecting duct, nephron, renal pelvis, calyx, urinary bladder, ureter, urethra:Collecting duct follows the nephron (not precedes it); calyx and pelvis ordering is

A. It coordinates sensory perception and integration:That is the primary role of the nervous system (sensory integration, not reproduction).
B. It synthesizes hormones for energy metabolism:Endocrine organs (e.g., thyroid, pancreas) are chiefly responsible for metabolic hormone synthesis; while reproductive organs produce sex hormones, their primary system role is reproduction.
C. It ensures the continuation of the species: The main biological function of the reproductive system is to produce gametes and enable fertilization and development, ensuring species propagation.
D. It regulates fluid balance within the body: Fluid/electrolyte balance is primarily regulated by the renal and endocrine systems (kidneys, ADH, aldosterone).
