Arthritis is painfull swelling in the body's joints, and is a greek word meaning 'joint'. arthritis is an umbrells term which looks over more than 100 different medical conditions. The most common type of arthritis is osteoarthritis. 8 million people in the UK have arthritis. Owl pellets are the indigestable parts(bones and teeth) of and owl's prey as the owl is a bird of prey and eats its food whole. What is in an owl pellet shows what kind of prey the owl has caught this commenly includes prey like mice,rodents,rabbits,squirrels,voles and many more small animals, in some owl pellets they find insects and fish. Owl's give put owl pellets around 20 hours after eating. Owl pellets are a good way for scientists to find out the structure of a skeleton of a mouse or what ever is in the owl pellet as the bones in an owl pellet are usually whole.(Lucy)

Arthritis is a common condition that causes pain and inflammation (Swelling) of the joints and bones. The main symptoms of arthritis include: Pain, stiffness, restricted movements of the joints and swelling. Over 9 million people in the UK suffer from arthritis. Arthritis is usually associated with older people but it can affect children aswell. This type of arthritis is known as Juvenille idopathic arthritis **(JIA).** JIA is uncommon affecting about 1 in 1,000 children. The main types of JIA are-

Owls swallow their food whole like many other birds. Birds don't have teeth so can't chew their food. Instead they use their strong, sharp beaks to rip their prey apart and swallow the food in large chunks. The Owl slowly digests its meal by seperating the meat and bones. The Owl then regurgitates the harder bits it can't swallow such as feathers and fur in the form of a pellet**.** Owl pellets are a good way for scientists to find out the structure of a skeleton of whatever is in the owl pellet as the bones in the owl pellet are usually whole. **(Iona)**

Arthritis causes a certain joint to swell up. A joint is where two or more bones meet for example the hip or knee. The bones of a joint have a smooth, elastic material called cartilage. The cartilage is basically a cushion to the bones which enables the joint to move about without pain. The joint also has a thin bit of tissue called synovium that makes a slippery liquid called synovial fluid that helps the joint and assists less friction between the bones. When any part in and around the joint becomes heated, it can lead to pain, puffiness and even determined mobility. __**(Lewis)**__
 * What exactly is Arthritis?**

Owls like most birds are not able to chew their food. But unlike other birds owls have an organ called a crop, which is used to store swallowed food to be digested later. Owls have a unique way of getting rid of any parts of their prey that cannot be digested. The indigestible parts are expelled from the owl 's body in an owl pellet. An Owl pellet usually has fur and feathers **__(Lewis)__**
