Which of the following is not true about the anatomy of the urinary system?

A. Lipid absorption: Absorption occurs in the small intestine after fats have been digested into smaller molecules. Bile salts do not absorb lipids directly.
B. Lipid emulsification: Bile salts break large fat globules into smaller droplets in a process called emulsification, which increases the surface area for digestive enzymes like lipase to act.
C. Lipid ingestion: Ingestion refers to eating, not the chemical processing of fats.
D. Lipid digestion: Digestion is primarily performed by lipase, not bile salts. Bile salts prepare fats for digestion.

A. Terminal sulcus: This is a V-shaped groove on the tongue that marks the division between the anterior and posterior tongue-not related to tongue mobility.
B. Lingual frenulum: This is a fold of mucous membrane under the tongue that may be too short or tight in some children (ankyloglossia or “tongue-tie”), limiting movement. Surgery may involve cutting this to free the tongue.
C. Uvula: The uvula is part of the soft palate and plays a role in speech and swallowing, not tongue movement.
D. Palatine tonsils: These are lymphatic tissues in the oropharynx and have no role in tongue movement.
