During human digestion, ingested food travels sequentially through the organs of the gastrointestinal tract for mechanical breakdown, chemical digestion, and nutrient absorption. Arrange the following anatomical structures in the correct order that food passes through after leaving the pharynx.

  1. 1Esophagus
  2. 2Stomach
  3. 3Small intestine
  4. 4Large intestine
  5. 5Rectum

Cevap

Esophagus → Stomach → Small intestine → Large intestine → Rectum
The digestive pathway begins when food moves from the oral cavity and pharynx down the esophagus. It enters the stomach for acid digestion and mechanical churning, flows into the small intestine for enzyme breakdown and nutrient uptake, passes into the large intestine for water reabsorption, and finally gathers in the rectum prior to elimination.

Adım Adım Çözüm

1
Identify the initial conduit from the throat
The esophagus receives the bolus after swallowing.
The esophagus is the primary muscular tube connecting the pharynx to the gastric compartment.
2
Identify the primary gastric breakdown site
The stomach receives food from the esophagus.
Gastric acids and enzymes churn the food bolus into semi-liquid chyme.
3
Identify the primary nutrient absorption site
The small intestine receives chyme from the stomach.
The duodenum, jejunum, and ileum absorb amino acids, sugars, and fatty acids into the bloodstream.
4
Identify the water reabsorption and consolidation site
The large intestine receives remaining material from the ileum.
The colon compacts waste by reabsorbing residual water and mineral salts.
5
Identify the terminal storage structure before excretion
The rectum stores solid waste prior to defecation.
The rectum acts as the final reservoir before stool exits through the anus.
