Endocrine disruptor hormones. The interrelationship between exposures to chemicals and health effects are rather complex. It is hard to definitively link a particular chemical with a specific health effect, and exposed adults may not show any ill effects. But, fetuses and embryos, whose growth and development are highly controlled by the endocrine system, are more vulnerable to exposure and may suffer overt or subtle lifelong health and/or reproductive abnormalities. Prebirth exposure, in some cases, can lead to permanent alterations and adult diseases. Some in the scientific community are concerned that exposure to endocrine disruptors in the womb or early in life may
Exocrine gland glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. Exocrine glands are named apocrine glands, holocrine glands, or merocrine glands based on how their products are secreted.
