Osteoid osteoma. Color enhanced axial computed tomography (CT) scan of the thigh showing osteoid osteoma (benign bone tumor) on the femur. The osteoid osteoma is revealed by a thickening of the bone connective tissues (blue) at the surface of the femur (white). A needle introduced until the tumor guides an opticfiber permetting its destruction with laser.

Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. 3D illustration. Protein digestion begins when you first start chewing.

Illustration of cystitis. -Intestinal bacteria (mainly Eschericha coli) from the rectum enter the urethra due to its close proximity in women. This is the reason why women are more subject to this infection than men, and why it can return more easily. -These bacteria are eliminated from the bladder during urination. -These bacteria remain in the rectum when the bladder and urethra are longer infected.
