Question

Choose the incorrect statement from the following

• A. Growth factors are essential for the normal growth of tissues and their repairing/regeneration
• B. GIP inhibits gastric secretion and motility
• C. The artial wall of our heart secretes atrial natriuretic factor (ANF), which increases blood pressure
• D. CCK acts pancreas and gallbladder stimulating the secretion of pancreatic enzymes and bile juice, respectively

Answer 1

The correct option is C The artial wall of our heart secretes atrial natriuretic factor (ANF), which increases blood pressure

Atrial natriuretic factor (ANF) is a hormone secreted by the atrial wall of the heart when there is an increase in the blood pressure. ANF causes the dilation of the blood vessels. The enlarging of the bood vessels increases blood flow resulting in a decrease in the blood pressure.
Growth factors are hormones that are secreted by non endocrine tissues. Growth factors stimulate normal cell growth and differentiation also promote repair and regeneration.
Gastric inhibitory peptide (GIP) is secreted by endocrine cells of the gastrointestinal tract. It is an inhibitory hormone. It inhibits gastric secretion and motility.
Cholecystokinin (CCK) stimulates the secretion of pancreatic enzymes and bile juice by gallbladder.
