Hormones

Secretin is produced in the small intestine, specifically in the duodenum. It is released in response to acidic chyme entering the duodenum from the stomach, and it helps stimulate the pancreas to release bicarbonate-rich fluids to neutralize the acidity.

Vasopressin is also called antidiuretic hormone (ADH) because it helps regulate water balance in the body by reducing urine production and increasing water reabsorption in the kidneys.

The juxtaglomerular cells located in the walls of the afferent arteriole secrete renin when they sense a drop in blood pressure. Renin is released into the bloodstream in response to decreased blood flow to the kidneys, ultimately leading to the activation of the renin-angiotensin-aldosterone system to help regulate blood pressure and fluid balance.

False. Beta cells of the pancreatic islets secrete insulin in response to high blood sugar levels, not glucagon. Glucagon is secreted by alpha cells in the pancreatic islets in response to low blood sugar levels to raise blood sugar levels.

Atrial natriuretic hormone promotes natriuresis and diuresis, which helps to reduce blood volume and blood pressure. It also inhibits the renin-angiotensin-aldosterone system, leading to vasodilation and decreased sodium reabsorption.

Most potent mineralocorticoid is fludrocortisone

The hormone called as thyroid stimulating hormone stimulates the production of the thyroid hormone. It comes from anterior lobe of the pituitary. There is negative feed back system to regulate the hormone production in your body.

The parathyroid glands produce and secrete parathyroid hormone which regulates calcium levels in the blood. Since it increases blood calcium levels, it promotes the function of osteoclasts, which reduce the calcium in bones and promote its increase in the blood stream.

Prolactin is primarily released from the pituitary gland, which is a small gland located at the base of the brain. It plays a key role in regulating lactation and reproductive functions in both males and females.

Oxytocin release is controlled by a positive-feedback mechanism during childbirth. When contractions of the uterus stimulate oxytocin release, this hormone further intensifies contractions, leading to more oxytocin release. This cycle continues until the baby is delivered.

Oxytocin is typically administered intravenously during labor by healthcare providers. It is delivered through an IV drip to help stimulate contractions and progress labor. The dosage and rate of infusion are carefully monitored to ensure both the safety of the mother and the baby.

Angiotensin-converting enzyme (ACE) inhibitors work by blocking the conversion of angiotensin I to angiotensin II, a powerful vasoconstrictor. By inhibiting this enzyme, ACE inhibitors help dilate blood vessels, reduce blood pressure, and improve blood flow, making them commonly used to treat conditions like hypertension and heart failure.

Growth hormone has more target cells in the body than any of the others listed. It acts on various tissues and organs to regulate growth, metabolism, and cell regeneration throughout the body.

long-term use of androstenedione, which is not in accordance with medical recommendations, may eventually have a negative effect on natural levels of testosterone, due to compensation on the part of the pituitary gland.

Oxytocin is made in the posterior pituitary. Oxytocin prompts the let-down reflex, and stimulates contraction of the uterus during childbirth.

The follicle-stimulating hormone (FSH) test is performed on men to evaluate testicular function. High levels of FSH may indicate primary testicular failure or low sperm production, while low levels may suggest a pituitary disorder affecting FSH production. This test helps diagnose infertility or hormonal imbalances in men.

Angiotensin-converting enzyme (ACE) tests measure the levels of ACE in the blood. Elevated ACE levels can indicate conditions like sarcoidosis, a lung condition that causes inflammation, or other granulomatous disorders. Decreased levels can occur in conditions like cirrhosis or Wilson's disease.

The erythropoietin (EPO) test is used to determine if hormonal secretion is causing changes in the red blood cells. The test has great value in evaluating low hemoglobin (anemia), and another disorder called polycythemia.

Aldosterone measurement is useful in detecting a condition called aldosteronism, which is caused by excess secretion of the hormone from the adrenal glands. There are two types of aldosteronism: primary and secondary.

Adrenocorticotropic hormone is a polypeptide tropic hormone produced and secreted by the anterior pituitary gland. It is an important component of the hypothalamic-pituitary-adrenal axis and is often produced in response to biological stress.

In adult males, the normal range for follicle-stimulating hormone (FSH) levels is typically between 1.5 to 12.4 milli-international units per milliliter (mIU/mL). Levels outside of this range may indicate issues with the reproductive system or hormone imbalance. Consulting with a healthcare provider for interpretation and further evaluation is recommended.

Serum Angiotensin-Converting Enzyme is also known as SACE (Serum Angiotensin-Converting Enzyme). It is an enzyme produced mainly by cells in the lungs and is involved in the regulation of blood pressure and electrolyte balance in the body. Elevated levels of SACE may be seen in conditions such as sarcoidosis.

Angiotensin I is a peptide hormone that is a precursor to Angiotensin II, which plays a role in regulating blood pressure and fluid balance in the body. Angiotensin I is converted to Angiotensin II by the enzyme angiotensin-converting enzyme (ACE).

Antidiuretic hormone (ADH) test, also called the Vasopressin test, is a test for the antidiuretic hormone, which is released from the pituitary gland and acts on the kidneys to increase their reabsorption of water into the blood.

An Angiotensin-Converting Enzyme (ACE) test measures the levels of ACE in the blood. ACE is an enzyme that plays a role in regulating blood pressure and fluid balance in the body. Abnormal levels of ACE can be associated with conditions such as sarcoidosis and other inflammatory diseases.
