It is called a double circulatory system because blood passes through the heart twice per circuit. The right pump sends deoxygenated blood to the lungs where it becomes oxygenated and returns back to the heart.
The presentation of an 18-month-old with hereditary fructose intolerance (HFI), deficiency of aldolase B and low blood glucose levels is due to accumulation of fructose-1 phosphate and the inhibition of glycolytic-gluconeogenic pathways.
Explanation:
Hereditary fructose intolerance leads to deficiency of fructose-1-phosphate aldolase enzyme. This enzyme deficiency leads to accumulation of fructose-1 phosphate in the liver. Fructose-1 phosphate inhibits the action of phosphorylase enzyme which monitors the glycogen to glucose conversion. Since glucose formation is reduced, hypoglycemia and lactic acidosis takes place accounting for the patient’s low blood sugar.
Answer:
They increase the levels of catecholamines—a family of brain chemicals that includes dopamine.
Explanation:
Stimulants are a class of drugs that “stimulate” the body's central nervous system, which includes the brain and spinal cord. They increase the levels of catecholamines—a family of brain chemicals that includes dopamine. These chemicals are used in the brain processes to signal reward and motivation.
