Which federal assistance program is specifically designed to provide nutritious, low-cost or free meals to children during the school day?

A. Gestational hypertension involves elevated blood pressure during pregnancy but does not include protein in the urine or the characteristic swelling seen in preeclampsia.

B. Preeclampsia is a pregnancy-specific condition characterized by high blood pressure, proteinuria (protein in the urine), and often edema (swelling), particularly in the hands, feet, and face. It usually develops after 20 weeks of gestation and can lead to serious complications for both mother and baby if untreated, including organ damage, seizures (eclampsia), and preterm birth. Early detection and monitoring are essential, and management may include antihypertensive medications, close fetal monitoring, and sometimes early delivery.

C. Premature birth refers to delivery before 37 weeks of gestation and is an outcome rather than a disease with these specific symptoms.

D. Gestational diabetes involves elevated blood glucose levels during pregnancy but does not typically cause protein in the urine or the characteristic swelling associated with preeclampsia.

A. The small intestine is the primary site of nutrient absorption in the digestive system. After food is mechanically broken down in the mouth and chemically digested in the stomach, it moves into the small intestine, where most nutrients are absorbed into the bloodstream or lymph. The inner lining of the small intestine contains finger-like projections called villi, which are covered by even smaller microvilli, forming the brush border. This structure greatly increases the surface area for absorption. Carbohydrates are broken down into simple sugars, proteins into amino acids, and fats into fatty acids and glycerol, all of which are absorbed here. Additionally, vitamins, minerals, and water are also absorbed in the small intestine, making it essential for overall nutrition and energy supply.

B. The gall bladder stores and concentrates bile produced by the liver. Bile is released into the small intestine to emulsify fats and aid in their digestion, but the gall bladder itself does not participate in nutrient absorption.

C. The bile duct is a conduit that transports bile from the liver and gall bladder to the small intestine. While it plays an important role in fat digestion, it does not directly absorb nutrients from food.

D. The oropharynx is part of the throat located behind the mouth, responsible for swallowing and directing food from the mouth to the esophagus. It has no role in nutrient absorption, which occurs further along in the digestive tract.
