Hormones

1. Biochemistry Lecture GBSN ( Unit 12) Hormones by, Miss Areesha Ahmad Lecturer

2. Amine hormones are  synthesized from the amino acids tryptophan or tyrosin Amine hormones are derived from a single amino acid, peptide and protein hormones consist of multiple amino acids that link to form an amino acid chain .

3. ligands released in the endocrine system are called hormones ,

4. Atria  of the heart ; Left atrium, Receives oxygenated blood from the lungs  Ventricles can refer to  the muscular chambers in the heart that pump blood,

5. Diuresis :  An increase in the amount of urine made by the kidney and passed from the body. Natriuresis : excretion of sodium in the urine Systemic vasodilation : increasing blood flow to poorly ventilated alveoli.  Pulmonary vasodilation : increase pulmonary blood flow . Endothelin is a local peptide hormone. Aldosterone is a steroid hormone

6. Melatonin   plays a role in the sleep-wake cycle Serotinin : controls your mood

7. Cholecystokinin is  a hormone produced in your small intestine

8. Gastrin is  a peptide hormone

9. Bicarbonate  : HCO3 Secretin ,  a digestive hormone secreted by the wall of the upper part of the small intestine

10. Endocrine System The endocrine system is a messenger system in organisms that uses hormones to regulate distant organs. Internal glands release hormones into the circulatory system, which then travel through feedback loops to target organs.  Some hormones produced by the endocrine system include: Melatonin: Controls sleep-wake cycles Oxytocin: Manages aspects of the reproductive systems and human behavior, including labor, delivery, and lactation Parathyroid hormone: Controls calcium levels in bones and blood Progesterone: Helps prepare the body for pregnancy Prolactin: Stimulates breast milk production after childbirth Testosterone: Contributes to sex drive and body density, and helps develop male sex characteristics Thyroid hormone: Helps control metabolism and energy levels, and plays a role in growth and development Follicle-stimulating hormone (FSH): Plays a role in sexual development and reproduction in both males and females Corticosteroid: Controls key functions in the body, including blood sugar levels, blood pressure, and muscle strength
