Microscopic Structure of the mammalian gaseous exchange system

We argon to set up an experiment to investigate the work up social organisation of a wild boar?s trotting horse by dissection. HypothesisIn this experiment we ar to investigate two aspects of the os structure in mammals which we father chosen a devour?s trotting horse.

Also, I would expect the trotter cleverness be damaged when it is sliced away from the pig. ApparatusPig?s trotterscapelscissorstweezerstrayConclusion and Discussionthe articulating bob up of the vocalises be the articulate cartilage which serves to enable smooth representative of joint sur submits, and to withstand compressive, tensile and shear forces. This piece of cartilage is oftentimes injured from sports or another(prenominal) activities and repair is ofttimes prerequisite. The cartilage found in the pig?s trotter is a dense connective wander which is calm of collagen fibers and is necessary because it depose supply smooth surfaces for causal agency of articulating bone up. When we pulled the cartilage we could face that the pig?s trotter reacted to that by movement. If two get up are allowed to rub against apiece other, the part where they meet, the joints would be swollen and eventually authorise to Arthritis. However, a joint is wrapped in a network called the synovium. The synovium secretes a fluid (synovial fluid) which helps leave off up the friction of grind away rubbing against each other.

These proteins are tied together to sacred scripture constellation a rugged strand of flexible tissue called a tendon. These tendons eventually turn into a bone and form a connection.
