This is a deeply peculiar question. Glands do not classify chemicals, they secrete chemicals, and the circulatory system does not disrupt chemicals, it distributes them.
Endocrine glands release chemicals directly into the bloodstream. These hormones are then carried by the circulatory system to their target tissues.
a hormone.
Endocrine glands secrete chemical messengers called hormones. These chemicals are secreted directly into the bloodstream, where they are carried by the circulatory system to target tissues throughout the body.
Endocrine glands secrete chemical messengers called hormones. These chemicals are secreted directly into the bloodstream, where they are carried by the circulatory system to target tissues throughout the body.
the circulatory system can deliver these chemicals (hormones) from one organ to another. for example, the hypothalamus and pituitary glands secrete hormones that work in other parts of the body
The circulatory system is responsible for transporting hormones from endocrine glands to target tissues.
The hormones produced by the endocrine glands are secreted directly into the bloodstream. The circulatory system then distributes these chemical messengers to target tissues throughout the body.
Ductless glands are part of the endocrine system. The endocrine glands secrete hormones. Because they have no ducts they secrete their hormones directly into the circulatory system.
mammary glands
The neurons responsible for communicating with glands to release chemicals are called motor neurons. These neurons transmit signals from the central nervous system to the glands to stimulate the release of various hormones or other chemicals into the blood stream.
Nerves tell glands when to release chemicals. Nerves send messages to glands. Apex- Nerves instruct glands to send out hormones.
