Unless fertilization occurs, the corpus luteum becomes scar tissue, which is known as the

A. "It is an enzyme released into the duodenum.":Salivary amylase is secreted into the mouth; pancreatic amylase is released into the duodenum.
B. "It is an enzyme that breaks down the fats in breast milk.":Salivary amylase digests starches (carbohydrates); lingual lipase (and gastric/pancreatic lipases) act on fats.
C. "It is an enzyme that initiates the breakdown of carbohydrates.":Salivary amylase begins starch digestion in the oral cavity by cleaving polysaccharides into smaller sugars.
D. "It is an enzyme that breaks down proteins in the stomach.":Proteolysis in the stomach is primarily by pepsin (a gastric enzyme), not salivary amylase.

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
