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.
The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.
