Hormones are the chemicals which are produced by glands. By definition they pour there secretion/secretions in blood. Blood carry the secretion through circulation to target organ/ organs for desired effect. Usually target organ sends back the message to reduce the secretion of the hormone producing gland. This is called as negative feed back effect. (Like thyroid stimulating orAdrenocorticotrophic hormone by anterior pituitary gland.) Sometimes hormone like Follicle stimulating hormone stimulates ovarian follicle. Which in turn produces hormone estrogen. Main female hormone. Thyroid hormones increase the 'basal metabolic rate' of body.

What female reproductive organ that produce hormones that develops in the secondary sex characteristic?
The ovaries are the female reproductive organs that produce hormones such as estrogen and progesterone. These hormones play a role in the development of secondary sex characteristics like breast development and regulation of the menstrual cycle.
What is the hormone responsible for the development and maintenance of female secondary sexual characteristic?
There are two hormones. For males it is testosterone and for females it is mainly estrogen.
What is a characteristic of hormones 1 act as a messanger molecule 2 act as a buffer in the bloodstream 3 inactivate bacteria or 4 coordinate visual responses?
Act as messenger molecules
Is a hormone a steroid?
Not all hormones are steroids. Steroids are a specific type of hormone that have a characteristic structure with four interconnected carbon rings. Other types of hormones, such as peptides and catecholamines, do not have this structure.
What are topic hormones?
These hormones stimulate the secretion of other hormones. Many hormones of hypothalamus are topic hormones.
The chemical secretions of the endocrine glands are called?
i think is hormones
What are hormones made from cholesterol called?
Steroid Hormones
Are capillaries permeable to proteins and if so, how does this characteristic impact the movement of substances within the circulatory system?
Yes, capillaries are permeable to proteins. This characteristic allows for the exchange of substances between the blood and surrounding tissues. Proteins can move in and out of capillaries, facilitating the transport of nutrients, hormones, and waste products throughout the circulatory system.
What is characteristic of steroid hormones such as estrogen?
Steroid hormones like estrogen are lipid-soluble molecules derived from cholesterol, allowing them to easily pass through cell membranes. Once inside the cell, they bind to specific intracellular receptors, leading to changes in gene expression and protein synthesis. This mechanism allows steroid hormones to exert long-lasting effects on various physiological processes, including development, metabolism, and reproductive functions. Additionally, they have a relatively slow onset of action compared to peptide hormones.
