The digestive system is an example of an organ system in which humans and other mammals exchange substances with the environment. The table shows its main tissues and organs, and their functions:
Monocryl is a synthetic, absorbable suture, manufactured and trademarked by Ethicon. It is composed of poliglecaprone 25, which is a copolymer of glycolide and epsilon-caprolactone.It comes both dyed (violet) and undyed (clear), and is a monofilament suture. It is generally used for soft-tissue approximation and ligation.t 1 week, its in vivo tensile strength is at 50-60% undyed (60-70% dyed), at 2 weeks its 20-30% undyed (30-40% dyed), and is essentially completely hydrolyzed by 91â119 days. When removed from the package, it has a high degree of memory, or coil.
Monoculture is the agricultural practice of producing or growing a single crop, plant, or livestock species, variety, or breed in a field or farming system at a time. Polyculture, where more than one crop is grown in the same space at the same time, is the alternative to monoculture. Monoculture is widely used in both industrial farming and organic farming and has allowed increased efficiency in planting and harvest. Continuous monoculture, or monocropping, where the same species is grown year after year, can lead to the quicker buildup of pests and diseases, and then rapid spread where a uniform crop is susceptible to a pathogen.
