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.
What else can I help you with?
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.
What organs do hormones travel from endocrine glands through bloodstream?
Hormones travel from endocrine glands through the bloodstream to reach target organs or tissues where they exert their specific effects. Some of the major endocrine glands that release hormones into the bloodstream include the pituitary gland, thyroid gland, adrenal glands, pancreas, and ovaries/testes.
Which system carries hormones from glands to all tissues?
The endocrine system carries hormones from glands to all tissues in the body. Hormones are chemical messengers that travel through the bloodstream to regulate various physiological processes and maintain homeostasis.
Do hormones travel through the blood stream?
Hormones travel In the blood because they need to travel in the body.
Endocrine glands produce hormones which are secreted directly into the extracellular space?
Yes, endocrine glands are specialized organs that secrete hormones directly into the bloodstream, rather than into ducts or directly outside the body. These hormones then travel through the bloodstream to target organs and tissues throughout the body where they regulate various physiological functions.
How do horomones travel throughout the body?
This depends whether the hormone is an EXOcrine hormone or an ENDOcrine hormone. EXOcrine hormones are secreted into a hollow cavity or the exterior to have a direct effect. I.e gastric hormones being secreted directly into the stomach to digest food. ENDOcrine hormone are secreted directly into the bloodstream to be carried to their target receptors and cells
How are hormones carried around the body?
Hormones are carried around the body through the bloodstream. They are produced by specialized glands and once released into the blood, they travel to target tissues where they exert their effects. Hormones bind to specific receptors on cells, triggering physiological responses.
What is a chemicals travel through the bloodstream and affect the activities of other cells?
I suppose that you think to oxygen.Oxygen is indispensable for life.
Chemicals that travel through the bloodstream and affect the activities of other cells?
Hormones
How do glands and hormones collaborate to regulate bodily functions?
Glands produce hormones that act as chemical messengers in the body. These hormones travel through the bloodstream to target organs and tissues, where they regulate various bodily functions. The glands and hormones work together to maintain balance and control processes such as growth, metabolism, and reproduction.
Are able to travel through the bloodstream and affect cells throughout distant part of the body?
Yes, substances in the bloodstream like hormones, nutrients, oxygen, and medications can travel throughout the body to affect cells in distant parts. This is how the body regulates functions and delivers essential molecules to different tissues and organs.
How fast do hormones travel through your body?
Hormones travel at varying speeds depending on the type of hormone and its mode of transport (bloodstream or nervous system). Generally, hormones can travel through the bloodstream to reach target tissues within seconds to minutes, while those transmitted through nerve pathways can act even more quickly.
