Pregnancy Hormones
Hormones during pregnancy are the result of an intricate interaction between hormones generated by different glands and Organ (biology), organs. The primary hormones involved comprise Human chorionic gonadotropin, human chorionic gonadotropin (hCG), progesterone, estrogen, Human placental lactogen, human placental lactogen (hPL), and oxytocin. Hormones are synthesized in certain organs, including the Ovary, ovaries, placenta, and pituitary gland. These hormones have essential functions in pregnancy test, maintaining the uterine lining, fetal development, preventing Preterm birth, premature labor, and the initiation and support of labor. Subsequently, the hormones are stored and released into the Circulatory system, circulation to be conveyed to the specific cells they are intended for. Once they reach the target cells, they are recognized by associated cell membrane or Receptor proteins, intracellular receptor proteins, leading to a cellular response. There are disorders related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gland
A gland is a Cell (biology), cell or an Organ (biology), organ in an animal's body that produces and secretes different substances that the organism needs, either into the bloodstream or into a body cavity or outer surface. A gland may also function to remove unwanted substances such as urine from the body. There are two types of gland, each with a different method of secretion. Endocrine glands are ductless and secrete their products, hormones, directly into interstitial spaces to be taken up into the bloodstream. Exocrine glands secrete their products through a duct into a body cavity or outer surface. Glands are mostly composed of epithelium, epithelial tissue, and typically have a supporting framework of connective tissue, and a capsule. Structure Development Every gland is formed by an ingrowth from an epithelium, epithelial surface. This ingrowth may in the beginning possess a tubular structure, but in other instances glands may start as a solid column of cells which ...
