[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.
It is recommended that your daily caloric intake should be made up of 40-60% carbohydrates. Most people would agree that making carbohydrates around 50% of your daily calorie intake is a good rule of thumb, and has been proven an effective ratio as part of a bodybuilding diet. So, how many grams of carbohydrates is that exactly? This is easy to determine when we know that 1 gram of carbohydrates equals 4 calories. 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. If you are bulking, you will need to consume between 300-500 calories above your maintenance level. If you are cutting, this number will be 300-500 calories below your maintenance level. You can determine your maintenance level by reading my post on how many calories to build muscle.
