= = Bones: 1. ** Long bones ** – Long bones are the longest bones in the body. Examples are the femur, the Humerus and Tibia. Both ends of the bone are covered in cartilage to help protect the bone and aid shock absorption. 2. ** Short bones ** – Short bones are defined as bones with a primary function of support and stability with limited movement. Examples are the Carpals and Tarsals – the wrist and foot bones. They have a relatively large amount of bone marrow 3. ** Flat bones ** – Flat bones are exactly as they sound. Strong, flat bones with the main function of providing protection to the body’s vital organs and being the base of muscles. The main example of a flat bone is the scapula, the sternum and the cranium. In adults, the highest numbers of red blood cells are formed in flat bones. 4. ** Irregular bones ** ­– These are bones in the body which do not fall into any other category, due to their shape. Good examples of these are the Vertebrae, Sacrum and Mandible (lower jaw). They primarily consist of cancellous bone, with a thin outer layer of compact bone.

=Mechanical Digestion:= Mechanical Digestion is the first step of digestion and begins when you swallow your food. Mechanical digestion is the process of chewing the food by teeth to break the ingested food into smaller pieces that can be more easily digested through chemical digestion =Chemical Digestion:= Most chemical digestion happens in the stomach. The food moves through your digestive system and is broken down into compounds and nutrients which your small intestine absorbs into the blood stream. The particles you don't absorb continue to move into the large intestine where water is removed.
