Answer:
Secretion of pancreatic fluid can be divided into three phases which correspond to the different stages of food ingestion. Each phase tends to induce a slightly different composition of pancreatic secretion with slightly different regulatory mechanisms. Cephalic Phase
This phase is initiated by the sensory experience of seeing and eating food and primarily involves vagus nerve stimulation of acinar cells to produce digestive enzymes. Because little aqueous sodium bicarbonate solution by ductal cells these enzymes lie inactive within the pancreatic acini and ducts.
Gastric Phase
This phase is initiated by the presence of food within the stomach and is once again primarily involves vagus nerve stimulation of acinar cells to produce digestive enzymes. By the end of the cephalic and gastric phases, the pancreatic ducts are filled with inactive digestive zymogens ready for washing out into the intestinal lumen by aquous sodium bicarbonate solution.
Intestinal Phase
This phase is initiated by emptying of stomach contents into the small Intestine and involves release of both secretin and cholecystokinin which stimulate pancreatic ductal cells to synthesize aqueous sodium bicarbonate solution. The generation of aqueous sodium bicarbonate solution washes out all of the inactive pancreatic enzymes waiting within the pancreatic ducts into the duodenum where they activated as discussed previously.
Explanation:
The exocrine pancreas secretes an aqueous mixture into the duodenum composed of digestive enzymes, which aid in further degradation of ingested food, and bicarbonate which helps neutralize stomach acid. Neutralization of gastric acid is a critical function of the pancreas as the small intestine mucosa is specialized for nutrient absorption and thus cannot possess a thick protective mucous layer similar to that of the stomach. Furthermore, pancreatic digestive enzymes are optimally active at basic pHs and thus pancreatic bicarbonate secretion is a key requirement for proper digestion.

Q.162.A 10 years old girl presented with fever and bruises for last 2 weeks. On examination she is pale; however there is no evidence of lymphadenopathy or hepatosplenomegaly. Her Hb is 6g/dl, TLC is 2700 and platelets are 90000. The most appropriate investigation to clinch the diagnosis is:
a)Bone marrow aspiration
b)Retics count
c)Bleeding time
d)PT and APTT
e)Factor VIII assay
Answer:
In a bone marrow aspiration, a health care provider uses a thin needle to remove a small amount of liquid bone marrow, usually from a spot in the back of your hipbone (pelvis).
A normal PT with an abnormal aPTT means that the defect lies within the intrinsic pathway, and a deficiency of factor VIII, IX, X, or XIII is suggested. A normal aPTT with an abnormal PT means that the defect lies within the extrinsic pathway and suggests a possible factor VII deficiency
Bleeding time is a medical test done on someone to assess their platelets function. It involves making a patient bleed, then timing how long it takes for them to stop bleeding using a stopwatch or other suitable devices.
The organ that is the first site of chemical digestion.
Answer:
The stomach
Explanation:
The stomach is the first place because your mouth and saliva do not do a chemical digestion, it only primes it for the chemical digestion in the stomach, plus the mouth is not a organ, it is a body part, for example the tongue or esophages are organs.
