State the function of the hormones oxytocin?
Dunno what it does in males (if anything). In females, it stimulates lactation, mostly. If given artificially, it can stimulate contraction of the uterus and parturition (doctors use it to induce labor). But it isn't really clear if the pituitary secretes oxytocin on its own to stimulate labor, or if there is some other mechanism that induces labor.
What effect does the hormone aldosterone have on the pH of blood plasma?
Short answer: In the kidney, aldosterone increases sodium retention, which increases potassium excretion, which increases H+ excretion, so aldosterone will tend to raise blood pH.
Explanation:
Aldosterone directly increases sodium retention in the kidney. ?Since all kidney cells have basolaterally located Na+/K+ ATPases, this will cause these exchangers to go into overdrive and dump more K+ into the cells. ?For those cells that have K+ channels, this will increase potassium excretion.
Finally, certain cells in your collecting ducts have H+/K+ exchangers (either the alpha or beta intercalated cells). ?So if you have more K+ in the lumen, this will cause these exchangers to kick into overdrive and dump H+ into the lumen, which finally raises blood pH.
What stimulates the release of gastrin?
Gastrin is released in response to the presence of food in the stomach. Stretch receptors in the stomach wall detect the presence of food and initiate the release of gastrin. Additionally, the presence of peptides and amino acids in the stomach also stimulate the release of gastrin.
What does parathyroid hormone convert?
parathyroid harmone;secreated by parathyroid glands.these are present on thyriod gland.and these are four in number.placed 2 in one part of thyroid gland and 2 in another part of thyroid gland.
its secreations;secreats paratharmone.
antoginstic to;it is acts antagonistic to calcitonin secreated by parafollicular cells or 'c' shaped cells present in thyroid gland.
- its functions;its main role is to regulate calcium levels in blood.it helps in decresing calcium levels in blood.while calcitonin helps in maitained ionised calcium levels in blood.
- it mainly acts on bones,smallintestine and renal tubules present in kidneys.
- action on bones;it causes bone reabsorption or demineralisation of bone.that means it absorbs calcium from bones .it acts on bones through osteoclasts.while absorbing calcium from bones there will be loss of mucopolysaccharide from bone matrix.
- action on smallintestine;it stimulates absorption of calcium in smallintestine.but ca and P occurs only in presence of vit-D presence.in deficiency of this vitamin ricketsoccurs.it ledas to osteoporosis.
- action on renaltubules;stimulates reabsorption of Ca from glomerular filterate.
- excreation;this harmone also helps in excreating in Ca and P in urine.
disorders;hyposecreation;causes low Ca levels in blood as a result muscular weakness occurs ,tetany also occurs.
hypersecreation;this causes decalcification of bones,and calcium starts get depositing in form of caliculi,in kidneys,pancreas.calcification also occurs in soft tissues even in pericardium.bones becomes weak due to excess demineralisation.
Prolactin is an example of a hormone high level of which causes infertility in women.It regulates milk production
During the first three months of pregnancy, estrogen and progesterone are produced by the corpus luteum in the ovary until the placenta takes over hormone production. These hormones support the growth and maintenance of the uterine lining for the implantation of the fertilized egg and prepare the mammary glands for milk production.
What happens if the body produces too much glucagon?
Glucagon can be given by injection to restore blood glucose lowered by insulin (even in unconscious patients). It can increase glucose release from glycogen stores more than insulin can suppress it. The effect of glucagon is limited, so it is very important to eat a carbohydrate meal once the person has recovered enough to eat safely.
Progesterone is secreted by what gland?
From wikipedia: Progesterone also known as P4(pregn-4-ene-3,20-dione) is a C-21 steroid hormone involved in the female menstrual cycle, pregnancy (supports gestation) and embryogenesis of humans and other species. Progesterone belongs to a class of hormones called progestogens, and is the major naturally occurring human progestogen.
Progesterone is commonly manufactured from the yam family, Dioscorea. Dioscorea produces large amounts of a steroid called diosgenin, which can be converted into progesterone in the laboratory.
False. The hypothalamus produces several hormones that regulate various functions in the body, including ADH (antidiuretic hormone) and oxytocin.
Does insulin has the opposite effect of glucagon?
Yes, insulin and glucagon have opposite effects in the body. Insulin helps lower blood sugar levels by promoting the storage of glucose, while glucagon raises blood sugar levels by stimulating the release of stored glucose from the liver.
Does cortisol has an anti-immunity effect?
Cortisol is known to have immunosuppressive effects as it inhibits the immune response by reducing the activity of immune cells such as T cells and suppressing the production of inflammatory molecules. This can make the body more susceptible to infections and diseases when cortisol levels are chronically elevated.
Aldosterone is a hormone that is produced by the adrenal glands. It works primarily on kidney (renal) cells to help maintain the balance of fluids and electrolytes in our bodies. Its mainly works to control reabsorption of sodium and chloride and secretion of potassium and hydrogen. If aldosterone production is not functioning properly, there can be serious consequences to the heart, kidneys and electrolyte balance.
Does insulin suppressed gluconeogenesis?
Yes, insulin suppresses gluconeogenesis. When insulin levels are high, it signals the body to use glucose for energy rather than create new glucose from non-carbohydrate sources like amino acids or fats. This helps regulate blood sugar levels and promotes storage of excess glucose for future energy needs.
What is the target organ for progesterone?
The target organ for progesterone is the ovary and the embryo
Function of inhibin hormones in males?
In males, inhibin hormones are produced by the testes and act to regulate the production of follicle-stimulating hormone (FSH) from the pituitary gland. Inhibin helps to provide negative feedback to the pituitary gland to reduce FSH secretion, which in turn helps to regulate the production of sperm in the testes.
What hormone inhibits osteoclast activity when blood calcium levels rise above normal?
Calcitonin is the hormone that inhibits osteoclast activity when blood calcium levels rise above normal. It helps regulate calcium levels in the blood by promoting calcium deposition in bones, thus decreasing blood calcium levels.
What gland secretes antidiuretic hormone?
The posterior pituitary gland secretes antidiuretic hormone (ADH), also known as vasopressin. ADH plays a key role in regulating water balance in the body by controlling the reabsorption of water by the kidneys.
How is adrenaline related to chemistry?
Adrenaline is a known chemical with a certain formula and structure. Its effects and actions are well known as part of biological chemistry, and can be readily predicted, reversed or duplicated.
When glucose levels in the blood drop below normal the pancreas releases a hormone called glucagon.?
Glucagon signals the liver to break down stored glycogen into glucose and release it into the bloodstream to raise blood glucose levels. This helps to maintain a stable level of glucose in the blood when levels are low.
What does the hormone Atrial natriuretic peptide do?
It inhibits release of renin from the kidneys and of aldosterone from the adrenal cortex.
The result is increased excretion of sodium ions and water from the kidneys and lowered blood volume and blood pressure. Or what you might be looking for is all of the above. :)
What is the role of FSH in female reproductive system?
FSH (Follicle Stimulating Hormone) is responsible for stimulating the growth and maturation of ovarian follicles in the female reproductive system. These follicles contain the eggs that will be released during ovulation. FSH also plays a role in the production of estrogen by the developing follicles.
What gland releases androgens?
In men, luteinizing hormone stimulates the production of male sex hormones called androgens by the inerstitial cells of the testes. Testosterone is the most important androgen.

Adrenaline has no withdrawal effects, but often the energy spent as a result of the fight-or-flight response can cause the tiring. However, because adrenaline increases blood flow to skeletal muscle, other organs may have impaired functioning for a period of time, but it probably isn't enough to cause any long-term impairments.
Somatostatin is also known as growth hormone inhibiting hormone (GHIH), which means that it inhibits, or reduces the production of growth hormone. This affects the development of muscle and bone.
By cleaning Amino Acids in the and dieing cells it reverts cells back to there original form. This process is only 3 minutes long from its time of release.
By cleaning broken & Damaged cells it restores the body of all forms of life back to its adult level. This definition is described as the fountain of youth.However in children this causes ailments and diseases due to them already being young.
Example: An teenager reaches maturity at age 21-30.This person is introduced to Somatostatin. This person will remain within that age. Not growing older no wrinkles no bone reduction or fat cell growth within bone or otherwise.
The body will balance this around with its natural HGH (Human Growth Hormone)
level.
Example 2:A 70 year old man or woman introduced to Somatostatin will be reverted back to there default age of 21-30. Some Abnormalities will occur. They will some changes with;
- hair coloring reverting to there original hair coloring
- Skin color will restore to there original blood cell count
- Reduction of unnecessary cells.(increased Fat loss)
- Massive increases in Metabolism
- Wrinkle receding
- Increased Energy
- Massive Increase of Vitality
- Vision increased
- Slight Increase in white blood cells
- Stabilization of nutrients in the body(less vomiting)
- Vocal an systemic muscles control
- Sexual Vitality restoration (Note:This does not cure Heavy Metal poison)
- Less Sleep
- Increased Memory & Awareness
- Physical Reaction increased
- Physical Strength Stabilized
- Bowl movements Normalized
(Note this was dated in 1984 and Currently Through the Use of rBST in all foods and drugs this age group now varies from adulthood from ages 8-12.)
The normal function of anti-cGH is balanced with HGH naturally in the body. Outside sources can disable this balance. Increases of HGH destabilizes this in Adults an will cause increases to Age. HGH that overwhelms GHIH.
This causes premature puberty this has been tested on millions of school children since 1984 through GMO food now avaible in all foods produced in the United States.Proving the benefit of HGH on children which almost instantly cause 8 year old girls to go into puberty and effectively become pregnant.An allow for a more mature youth force and reduction in matured Adults.
This test was proven very effective by the FDA & Monsanto Project To increase aging in children to prevent Autism & Dwarfisim. Which is caused by increased amounts of Somatostain in children.
