[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]. The lumen of the trachea is lined by pseudostratified columnar epithelium. Note that all the surface cells have cilia at their free (apical) surface.
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.
Letâs say you need to consume 3,000 calories per day to build muscle. If carbohydrates make up 50% of your diet, you will need to consume 1,500 calories worth of carbohydrates. At 4 calories per gram, 1,500 divided by 4 would equal about 375 grams of carbohydrates every day. Your own caloric intake will vary a lot based on your own personal goal and BMR.
