What hormones could be implicated in failing to maintain the pregnancy during the first trimester?
Oestrogen, Progesterone and small amounts of Androgen and Testosterone (male hormones) are produced in the Ovaries. Oestrogen: regulates the menstrual cycle and prepares the breasts for milk production. Progesterone: prepares the lining of the uterus, for implantation of a fertilized egg, and helps maintain the pregnancy.
homeostasis is maintained through hormones the circulatory system will send to the brain.
DNA helps maintain homeostasis by the proteins and lipids associated with DNA and RNA. These proteins and fats regulated both hormones and growth.
Hormones belong to the endocrine system, which releases hormones from endocrine glands to maintain homeostasis in the body. There are many different types of hormones travelling through the body but each hormone is only designed to work on specific target cells.
The nervous system, which controls the endocrine glands, telling them when to release hormones The circulatory system, which transports the hormones to target cells You could also include the urinary system; whilst the kidneys are a part of the endocrine system, their other role is to excrete water & salts - the levels of both of which help to maintain homeostasis
Placenta.
One of the major hormones of pregnancy, estrogen helps maintain the endometrial lining of the uterus. Additionally, progesterone will also help to maintain the uterine lining.
produce many hormones which affects the pregnancy and maternal physiology.
The placenta secretes HCG in order to stimulate the production of hormones required to maintain a pregnancy.
Corpus luteum secrets an hormone called Progesterone that maintains the lining of the endometrium and sustains pregnancy
the corpus lutem is the remnant of the ruptured follicle. It lives for 14 days and secretes hormones needed to maintain a pregnancy
Estrogen
Endocrine glands secrete hormones which help maintain homeostasis.
The effect of thyroid hormones on the cells of the body is regulation of metabolism of those cells.
Not until death. All sorts of hormones are used constantly to maintain the body's homeostatic balance.
Pregnancy and lactation increase the BMR because of the high energy required to maintain the pregnancy and lactation.
I am afraid it is unlikely. Ovary swelling is normal as cells in the sac the egg came from grow to provide hormones to maintain a pregnancy but if there is no embryo in the sac you have what is called a blighted ovum which cannot develop into a baby.
