Answer the following question given this paragraph: Diabetes mellitus is a disorder of glucose metabolism in which insulin production by the pancreas is impaired. Since insulin helps glucose enter the cells, a decrease of this hormone means that glucose cannot be used in its normal fashion. When this happens, the body begins to break down fats, producing a decrease in blood pH. Chemical systems in the body can balance this pH shift for a while, but excessive acid production can create serious problems if not corrected by administering insulin to restore normal glucose use. Q: What is a disorder of glucose metabolism in which insulin production by the pancreas is impaired? Choices: - cluster mellitus - populations mellitus - sugar mellitus - diabetes mellitus A:
diabetes mellitus
Answer the following question given this paragraph: 19.5 Development of the Heart The heart is the first organ to form and become functional, emphasizing the importance of transport of material to and from the developing infant. It originates about day 18 or 19 from the mesoderm and begins beating and pumping blood about day 21 or 22. It forms from the cardiogenic region near the head and is visible as a prominent heart bulge on the surface of the embryo. Originally, it consists of a pair of strands called cardiogenic cords that quickly form a hollow lumen and are referred to as endocardial tubes. These then fuse into a single heart tube and differentiate into the truncus arteriosus, bulbus cordis, primitive ventricle, primitive atrium, and sinus venosus, starting about day 22. The primitive heart begins to form an S shape within the pericardium between days 23 and 28. The internal septa begin to form about day 28, separating the heart into the atria and ventricles, although the foramen ovale persists until shortly after birth. Between weeks five and eight, the atrioventricular valves form. The semilunar valves form between weeks five and nine. Q: In humans, what is the first organ to form and become functional? Choices: - brain - liver - pancreas - heart A:
heart

*Question*
Answer the following question given this paragraph: Blood from the lungs enters the left atrium of the heart. The left atrium pumps the blood to the left ventricle, which pumps it to the body. This loop is represented by the red arrows in Figure above . Q: Which side of the heart does blood from the lungs enter into? Choices: - right ventricle - left ventricle - right atrium - left atrium A:
**Answer**
left atrium
