The definitions are,
Hormone that stimulates multiple digestive processes.
Enzyme that begins protein digestion.
Produce acid and intrinsic factor.
Liquid produced as a result of stomach churning.
Produce pepsinogen.
Cells in gastric glands that produce hormones.
Controls passage of bolus from esophagus to stomach.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes.
