â Blood viscosity â Total blood vessel length â Blood vessel diameter Resistance â¢ Factors that remain relatively constant: â Blood viscosity â¢ The stickiness of blood due to formed elements and plasma proteins â¢ Increased viscosity = increased resistance â Blood vessel length â¢ Longer vessel = greater resistance encountered
Jasmonic acid (JA) is derived from the fatty acid linolenic acid. It is a member of the jasmonate class of plant hormones. It is biosynthesized from linolenic acid by the octadecanoid pathway.
Introduction. Parietal cells in the stomach secrete roughly two liters of acid a day in the form of hydrochloric acid. Acid in the stomach functions to kill bacteria, and to aid digestion by solubilizing food.The acid is also important to establish the optimal pH (between 1.8-3.5) for the function of the digestive enzyme pepsin.arietal cells in the stomach secrete roughly two liters of acid a day in the form of hydrochloric acid.
