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.
By Laura Klappenbach. Monotremes (Monotremata) are a unique group of mammals that lay eggs instead of giving birth to live young like other mammals (such as placental mammals and marsupials). Monotremes include several species of echidnas and the platypus.Monotremes differ from other mammals in that they have a singoe opening for their urinary, digestive and reproductive tracts (this single opening is known as a cloaca and is similar to the anatomy of reptiles).onotremes lay eggs and like other mammals lactate (produce milk) but instead of having nipples like other mammals, monotremes secrete milk through mammary gland openings in the skin. Adult monotremes do not have any teeth. Monotremes are long-lived mammals.
