endocrine system and neurotransmitters in the nervous system. The nervous system plays a role in certain sustained responses—controlling day/night cycles and reproductive cycles in many animals‚ for example—often by increasing or decreasing secretions from endocrine glands. The fundamental concepts of biological control systems are important in regulation by hormones. A receptor‚ or sensor‚ detects a stimulus and sends information to a control center. After comparing the incoming information

The article that I read discussed the two main types and most common forms of diabetes‚ but it also discussed gestational diabetes. Gestational diabetes generally occurs in women who are older in age‚ a personal or family related health history‚ or are more obese.

dart frog. The Choco’ tribe in Colombia‚ South America uses the skin secretions to poison their dart tips. One technique used to treat darts requires that a sharp stick to be forced into the frog’s mouth and down its throat. While on the stick‚ the frog is held over a fire. This causes the animal much stress and it begins to release the toxic alkaloids and produces a white bubble. Darts that are dipped or rolled in this secretion and

Two types of sweat glands can be found in humans: eccrine glands and apocrine glands. The eccrine sweat glands are distributed over much of the body. In humans‚ sweating is primarily a means of thermoregulation which is achieved by the water-rich secretion of the eccrine glands. Maximum sweat rates of an adult can be up to 2-4 liters per hour or 10-14 liters per day‚ but is less in children prior to puberty. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling

genital secretions that can serve as targets for HIV (e.g.‚ CD4+ cells). Increased infectiousness. STDs also appear to increase the risk of an HIV-infected person transmitting the virus to his or her sex partners. Studies have shown that HIV-infected individuals who are also infected with other STDs are particularly likely to shed HIV in their genital secretions. For example‚ men who are infected with both gonorrhea and HIV are more than twice as likely to have HIV in their genital secretions than
