[Trachea, monkey; x-section, PTS]. The lumen of the trachea is lined by pseudostratified columnar epithelium. Note that all the surface cells have cilia at their free (apical) surface.(What function do these cilia serve in the trachea?) Mucus-secreting unicellular gland cells (goblet cells) are interspersed among the ciliated cells.Trachea, monkey; x-section, PTS].

Complex Carbs on Restrictive Low-Carb Diets. If you're on a restrictive low-carb diet, you may be limited to just 20 grams of net carbs per day. That excludes virtually any food rich in complex carbohydrates, as a single serving of any of the previously mentioned foods contains more than your daily limit.
In general, how many grams of carbs per day you should consume is probably going to be in between 500 and 800 calories from carbohydrates, and thatâs typically about 150 to 200 grams of carbohydrates per day â 200 is an upper amount and goes as low as 120, which may be ideal for many trying to trim down.
