A proper kidney diet contains a good amount of protein and other nutrients that are necessary to help keep hair and nails healthy. People with CKD are at high risk for deficiencies in zinc, calcium, iron and B vitamins.
The pharynx is the part of the digestive system situated posterior to the nasal and oral cavities and posterior to the larynx. It is therefore divisible into nasal, oral, and laryngeal parts: the (1) nasopharynx, (2) oropharynx, and (3) laryngopharynx. The pharynx extends from the base of the skull down to the inferior border of the cricoid cartilage (around the C6 vertebral level), where it becomes continuous with the esophagus.
1 The pharynx is a muscular tube that provides a passageway for food and air. 2  The esophagus is a muscular tube that completes the passageway from the pharynx to the stomach. 3  The stomach is a C-shaped organ located on the left side of the abdomen beneath the diaphragm (Figure 14.3).
