The respiratory tract is lined with respiratory mucosa or respiratory epithelium. Tubuloalveolar serous secreting glands lying in the lamina propria of the olfactory mucosa. Grapefruit inhibits the metabolism of albendazole within the intestinal mucosa. The stimulation of the mechanical receptors located in the gastric mucosa stimulates the vagus afferents. Symptoms often include constipation, toxic and allergic reactions, irritation of the intestinal mucosa, and malnutrition. The trachea and bronchi have plexuses of lymph capillaries in their mucosa and submucosa. They are absorbed well from the stomach and intestinal mucosa. These host cells are generally M cells and Peyer's patches of the intestinal mucosa. Findings on gastroscopy may include edematous gastric mucosa, and hyperperistalsis. The vaginal mucosa is absent of glands. It is a large hydrophilic molecule that partitions poorly across the gastrointestinal mucosa. It is a superficial cyst in the alveolar mucosa. The nasal congestion is due to dilation of vessels in the nasal mucosa. For nasal mucosa, sinuses, bronchi, and lungs. It may also result from inflammation or congestion of the vaginal mucosa.
