Describe how red blood cells is regulated by the negative feedback system including the hormones?
Red blood cell production is regulated by a negative feedback system:
As the oxygen carrying capacity of red blood cells decreases due to High altitudes for example, the bodies requirements for oxygen increase; thus new Red blood cells need to be produced
the drop in oxygen-carrying capacity is referred to as Hypoxia; which is in turn detected by cells within the KIDNEY; when low oxygen levels are detected these cells within the kidney release a hormone called erythropoietin
Erythropoietin stimulates the RED BONE MARROW to produce more erythrocytes (Red blood cells); a process caller erythropoiesis. This then causes an INCREASE in red blood cell count and thus an INCREASE in oxygen carry capacity of the body
This increase is again detected by cells in the KIDNEY and the release of erythropoietin is decreased; restoring the oxygen carrying capacity back to normal

How is the menstrual cycle an example of the body's use of negative feedback?
The menstrual cycle is regulated by negative feedback involving hormones such as estrogen and progesterone. When hormone levels drop, it triggers the release of other hormones to stimulate the uterine lining shedding (menstruation). Once hormone levels rise again, it signals the end of menstruation and the start of a new cycle, maintaining balance through negative feedback mechanisms.
What is the human reproductive system regulated by?
The human reproductive system is primarily regulated by hormones, which are produced by the endocrine glands such as the hypothalamus, pituitary gland, and gonads (testes in males, ovaries in females). These hormones control the development of sexual characteristics, maturation of germ cells, and the menstrual cycle in females. The release of these hormones is tightly regulated to maintain proper reproductive function.
Hormone production is self regulated by which mechanism?
Hormone production is self-regulated through a negative feedback mechanism. This means that when hormone levels in the blood reach a certain threshold, the body signals the glands to stop producing that hormone until levels drop back down. This helps maintain a balance of hormones in the body.
Is gonadotropin negative feedback or positive feedback?
Gonadotropin release is primarily regulated by negative feedback mechanisms. In both males and females, sex hormones (like testosterone and estrogen) inhibit the secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus and luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. However, during specific phases of the menstrual cycle, estrogen can induce a positive feedback loop leading to a surge in LH, which triggers ovulation. Overall, the predominant regulatory mechanism for gonadotropin is negative feedback.
What is the body's metabolism regulated by?
The body's metabolism is mainly regulated by hormones such as insulin, cortisol, and thyroid hormones. These hormones control processes like energy storage, breakdown of nutrients, and overall metabolic rate. Other factors that can influence metabolism include genetics, muscle mass, and physical activity levels.
How is hormones secreation regulated?
mainly by feedback mechanism
What is the production of hormones from the pituitary gland regulated by?
The production of hormones from the pituitary gland is regulated by the hypothalamus, which secretes releasing and inhibiting hormones that control the release of hormones from the pituitary gland. Feedback loops involving target organs also help regulate hormone production by providing information on hormone levels in the body.
Is menstrual cycle a feedback mechanism?
Yes.The Menstrual cycle is a feedback mechanism because it is regulated by hormones which are controlled by negative feedback mechanisms. This mechanism includes hormones that are interacted with tissues in the menstrual cycle.
Positive feedback differs from negative feedback in that?
Most of the mechanisms in our body are regulated by negative feedback inhibition. In this type of process, the end product shuts off or reduces the intensity of the original stimulus. Production of certain hormones when mother is giving birth to a child is regulated by positive feedback inhibition. In this type of process, response leads to an even greater response.
Do most hormones regulate by negative feedback mechanisms?
Yes and most biochemical path ways are regulated by negative feedback. Enough of the product made inhibits the enzyme, or biochemical pathway, from making more product/reactions.
The reproductive cycle of a human is usually regulated by?
hormones
Bone growth during childhood and in adults is regulated and directed by?
Growth Hormones, Thyroid Hormones, Sex Hormones and Mechanical Stress
What hormones are regulated by positive feedback under certain circumstances?
Oxytocin in the process of giving birth. Oxytocin causes uterine contraction, which causes the baby to push up against the cervix, which causes more oxytocin to be released. And the cycle continues until the baby is born.
The human reproductive system is regulated by?
hormones
What hormones is regulated by a neuroendocrine reflex?
oxytocin
What are the hormonal responses and describe them?
The hormonal responses are basically responses or reactions given by the hormones. This response is triggered by either negative or positive feedback mechanism. When the hormone level is too low, the gland (usually endocrine) releases the hormones into the bloodstreams where it travels until it reaches the target organ. When there are too much hormones, the gland is triggered to stop the release of hormones. This mechanism of maintaining the balance without giving excess amount of hormone is known as negative feedback. In a positive feedback, the gland is triggered to release more hormones when excess amount of hormones is present.
Which hormones is regulated by a neuroendocrine (letdown) reflex?
The neuroendocrine "letdown" reflex is regulated by oxytocin.
