Question

which body cavity contains the organs of digestion and excretion?
○ spinal cavity
○ thoracic cavity
○ pelvic cavity
○ abdominal cavity

Explanation:

• The spinal cavity holds the spinal cord, not digestive/excretory organs.
• The thoracic cavity contains heart and lungs, not related to digestion/excretion.
• The pelvic cavity holds reproductive and some excretory (like bladder) but not main digestive organs.
• The abdominal cavity contains organs like stomach, intestines, liver (digestion) and kidneys (excretion - though kidneys are also in retroperitoneal space, the abdominal cavity houses many digestive organs and is the primary cavity for digestion - related organs and some excretory - associated structures in the abdominal region).

Answer:

D. Abdominal cavity
