At maturity, there are roughly 30 [4]–37 [5] [6] trillion cells in the body, an estimate arrived at by totaling the cell numbers of all the organs of the body and cell types. The skin is the body's largest organ, and it plays a vital role in protecting us from external elements. Urine passes into the ureters, tubes of smooth muscle that convey urine from the kidneys to the urinary bladder.

The subcostal muscles are strips of muscle located on the internal surface of the lower ribs, sharing a plane with the innermost intercostals. In addition, it extends, rotates (contralateral) and laterally flexes (ipsilateral) the head and neck. The pectoralis major forms the anterior wall of the axillary region, or the armpit (see this page), which becomes apparent when the upper arm is positioned away from the torso. It removes waste materials from the blood through urine, which carries a variety of waste molecules and excess ions and water out of the body.For example, the nervous system and the endocrine system operate together as the neuroendocrine system.

The gray matter is where the instructions generate, while the white matter is the path through which the instructions travel toward the organs.That range of motion will be covered in future tutorials but for now, we will do an exercise using these tilted boxes and a line that connects them to get comfortable with drawing these proportions. The immune system consists of the white blood cells, the thymus, lymph nodes and lymph channels, which are also part of the lymphatic system. Quadratus lumborum is involved in extending the trunk and flexing it laterally to the ipsilateral side.

The breast form, a combination of glandular and fatty tissue forms, is attached to the fascia (a sheathing layer) that is situated over the pectoralis major muscle. The torso also harbours many of the main groups of muscles in the tetrapod body, including the pectoral, abdominal, lateral and epaxial muscles.Having gallstones is a risk factor for gallbladder cancer which although quite uncommon is rapidly fatal if not diagnosed early. They support the intercostal spaces and thoracic cage, and depress the ribs during forced expiration. For descriptive purposes, the muscles of the back are divided into two groups; superficial (extrinsic) muscles which move the upper limb and deep (intrinsic) muscles which act on the trunk. Third, the muscles of the torso do not move just the torso (vertebral column and rib cage) but also the shoulder girdle, which includes the scapula bones and clavicles, as well as the upper arms (humerus bones).
