The gastric cells that secrete hydrochloric acid and intrinsic factor are the

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. Vocal cords: The vocal cords (vocal folds) are mucosal folds that lie within the larynx and produce sound when they vibrate
B. Thyroid cartilage: The thyroid cartilage is the largest laryngeal cartilage (forms the “Adam’s apple”) and provides structural support to the larynx
C. Cricoid cartilage: The cricoid cartilage is a complete ring of cartilage inferior to the thyroid cartilage that forms part of the laryngeal skeleton
D. Laryngopharynx: The laryngopharynx is the lower part of the pharynx (shared passageway for food and air) that lies posterior to the larynx; it is pharyngeal tissue, not a structural component of the larynx itself
E. Epiglottis:The epiglottis is a flap of elastic cartilage attached to the entrance of the larynx that prevents aspiration during swallowing
F. C-rings: “C-rings” typically refer to the incomplete C-shaped cartilaginous rings of the trachea, not the larynx
