How could one or more hormone either fsh lh oestrogen or progesterone be used to treat infertility from a biology gcse paper?

Hormones such as FSH (follicle-stimulating hormone) and LH (luteinizing hormone) can be used to treat infertility by stimulating ovulation in women who have irregular or absent ovulation. FSH promotes the growth and maturation of ovarian follicles, while LH triggers the release of an egg during ovulation. In some cases, estrogen or progesterone may be administered to help prepare the uterine lining for implantation or to support early pregnancy. This hormonal therapy can enhance the chances of conception for individuals experiencing fertility issues.

What does renin activate?

Renin mediates extracellular volume (i.e., that of the blood plasma, lymph and interstitial fluid), and arterial vasoconstriction. Thus, it regulates the body's mean arterial blood pressure.

It activates the renin-angiotensin system by cleaving angiotensinogen, produced by the liver, to yield angiotensin I, which is further converted into angiotensin II by ACE.

Angiotensin II then constricts blood vessels, increases the secretion of ADH and aldosterone, and stimulates the hypothalamus to activate the thirst reflex, each leading to an increase in blood pressure.

Is thyroid stimulating hormone level tested in liver function panel?

No, TSH or thyoroid stimulating hormone is a test of the function of your thyroid gland located below the lymph nodes in your neck. A basic liver panel typically consists of AST, ALT, Alkaline Phosphotase, LDH, and Bilirubin. TSH would be a part of a complete metabolic panel in most laboratories, but not a basicmetabolic panel or basic liver panel screening.

What function does the Ghrelin hormone do?

The Ghrelin hormone is an appetite regulating hormone. It is produced in the pancreas and also functions in helping growth. It also plays a role in adapting to environment change and the learning processes.

Why would I have progesterone in my ovary?

Ovaries make both estrogen and progesterone. Progesterone is released with the eggs and for a while after to help the body prepare for the possibility of pregnancy. If pregnancy doesn't occur, then the lesion on the ovary where the egg cell was released dries up and shrinks, reducing progesterone, and estrogen rises again. If pregnancy does occur, the corpus luteum (literally "yellow body") continues to secrete progesterone for the rest of the month until the growing placenta can take over that job. The placenta also produces a great deal of estriol (a weaker form of estrogen which helps prepare the breasts without harming the fetus or causing any reproductive symptoms).

The prefix "pro-" means "for," "gest" is the same root as in the word gestation, and, "sterone" is a common ending for steroid hormones. So literally, the word progesterone means "a hormone for helping pregnancy."

Is adrenaline a steroid?

How many types of prostaglandins are there?

There are over 16 types falling into 9 structural classes.

What gland secretes seven hormones that all use CAMP as the secondary messenger?

The gland that secretes seven hormones using cyclic AMP (cAMP) as a secondary messenger is the anterior pituitary gland. These hormones include adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), growth hormone (GH), prolactin, and melanocyte-stimulating hormone (MSH). The use of cAMP as a secondary messenger helps amplify the signal and activate various cellular responses.

Is Regular Insulin and NPH insulin the same thing?

NPH is a long acting insulin that peaks 8 hours after administration. Regular insulin is fast acting that peaks 30 minutes after administration. Regular insulin should be taken before meals.

How do insulin and glucagon reach distant cells in the liver?

To understand you need to know the anatomy of the portal vein system. The pancreatic veins drain into the major splenic vein which all drain into the hepatic portal vein. Although the artery supplying the pancreas is directly from the desceding aorta. The hepatic portal vein drains into the Liver. So insulin and glucagon are released into the splenic vein and eventually reach the liver via the portal system.

What is the importance of aldosterone?

It is produced by the adrenal glands. It regulates sodium and potassium levels in the body.
