Are target tissues close to the glands that affect them?
most endocrine hormones are circulating hormones not local hormones.
Hormones affect specific tissues called?
Hormones work by affecting Target Organs
What does the organs influenced by hormones are called?
They are the target organs. Hormones act on the target organs
How do your hormones travel?
The endocrine glands secrete hormones directly into the bloodstream. The hormones then travel to target tissues via the circulatory system.
Which system is responsible for transporting hormones from endocrine glands to various body tissues?
The circulatory system is responsible for transporting hormones from endocrine glands to target tissues.
Do Major hormones circulate to virtually all tissues?
Yes, all hormones are released into the blood stream and then circulate to all tissues; only those target tissues that are designed to react to specific hormones will react to the presence of the hormone. Hormones are chemical messengers that are released into the blood stream, designed to cause changes in only certain tissues.
What are target tissues?
when the chemicals arrive in the right places, the target tissues, they start to do their work. a group of cells that have receptors embedded in the plasma membrane that are complementary in shape to specific hormone molecules. Only these cells will respond to that specific hormone.
Endocrine glands release chemicals directly to what?
Endocrine glands release chemicals directly into the bloodstream. These hormones are then carried by the circulatory system to their target tissues.
What are the chemicals secreted by the endocrine system?
The chemicals secreted by the endocrine system are known as hormones. These chemical messengers are carried by the circulatory system to their target tissues.
If hormones travel in the bloodstream why don't all tissues respond to all hormones?
The tissue/cells need a receptor that can interact with that hormone in order to respond to it. This receptor may be on a cell membrane, inside the cell, or even inside the nucleus (in the case of steroid hormones, for example.) Like many organic chemicals in the body, they have structures which result in certain parts of the molecule being presented to cells (active sites). Because cells and tissue have different structures as well, only certain cells will react to the presence of a particular hormone. Many hormones have antagonist hormones that cause an opposite effect. This helps control negative feedback when the target organ's hormone levels are too high.
Do Endocrine hormones act as chemical messengers?
Yes, endocrine hormones act as chemical messengers. The circulatory system carries them to target tissues, where they carry messages to regulate body processes.
What is the difference between plant hormones and animal hormones?
The plant hormones different parts of the plants in a different way while the animal hormones affect the target cells in more than one organ.
