Trematodes generally lack any specialized sense organs, although some ectoparasitic species do possess one or two pairs of simple ocelli. Reproductive system
Most trematodes are simultaneous hermaphrodites, having both male and female organs. Blood flukes are the only form of trematodes that are not hermaphrodites, meaning they have both a male and female sex. Blood flukes are unique in the way that they can reproduce sexually and asexually. In order for the reproduction of blood flukes to occur asexually, infecting a freshwater snail must happen to act as an intermediate host. Acting as an intermediate host, an organism that supports non-reproductive parasites, allows for the blood flukes to gather nourishment to reproduce. The asexual reproduction takes place in the hepatopancreas of the snail. Reproduction of blood flukes sexually involves finding a mammal host to act as an intermediate host to support their nutritional needs.The reproductive system of trematodes usually consist of having two testes, which are found posterior and dorsal to the ventral sucker. Having sperm ducts that join together on the underside of the front half of the animal. This final part of the male system varies considerably in structure between species, but may include sperm storage sacs and accessory glands, in addition to the copulatory organ, which is either eversible, and termed a cirrus, or non-eversible, and termed a penis.There is usually only a single ovary. Eggs pass from it into an oviduct. The distal part of the oviduct, called ootype, is dilated.
The goal is to consume 10-20 grams of a carbohydrate to raise blood glucose levels to a minimum of 70 mg/dL (3.9 mmol/L).Examples of products to consume are:

Glucose tabs or gel (refer to instructions on packet)
Juice containing sugar like apple, grape, or cranberry juice, 4 ounces or 1/2 cup
Soda or a soft-drink, 4 ounces or 1/2 cup (not diet soda)
Candy
Table sugar or honey, 1 tablespoonImprovement in blood sugar levels and symptoms are expected to occur in 15–20 minutes, at which point blood sugar should be measured again. If the repeat blood sugar level is not above 70 mg/dL (3.9 mmol/L), consume another 10-20 grams of a carbohydrate and remeasure blood sugar levels after 15–20 minutes. Repeat until blood glucose levels have returned to normal levels. The greatest improvements in blood glucose will be seen if the carbohydrate chewed or drunk, and then swallowed. This results in the greatest bioavaliablity of glucose, meaning the greatest amount of glucose enters the body producing the best possible improvements in blood glucose levels. The second best way to consume a carbohydrate it to allow it to dissolve under the tongue, also referred to as sublingual administration. For example, a hard candy can be dissolved under the tongue, however the best improvements in blood glucose will occur if the hard candy is chewed and crushed, then swallowed.After correcting blood glucose levels, people may consume a full meal within one hour in order to replenish glycogen stores.
