  • 1. By: SaruVaan, ShaHuma, ShaNiya, ShaMila, SaNa, and Iffath Endocrine System Biology
  • 2. Brief Introduction ENDOCRINE SYSTEM Vertebrate hormones regulate such diverse activities as; Growth Development Reproduction Metabolic Rate Fluid Balance Blood Homeostasis And Coping with stress Hormones Regulations 21 Hormones are Regulated by the Glands In this Presentation, Mainly we are going to explain about the Classical Human Endocrine glands
  • 3. ENDOCRINE GLANDS Hypothalamus Pituitary glands 1 2 3 4 5 6 Pineal gland Thyroid gland Parathyroid glands Thymus gland Adrenal gland Pancreas Testes 7 8 9 Ovary10
  • 4. Your Logo  Controls an immense amount of our bodily functions.  Located in the middle of the base of the brain and encapsulates the ventricle portion of the third ventricle. Hypothalamus
  • 5. Your Logo • Located in the center of the skull. • the size of the Pituitary gland is about the size of a pea. • Important link between the nervous system and the endocrine system and releases many hormones which affect • Growth • sexual development • metabolism • system of reproduction • . The pituitary gland has two distinct parts, the anterior and the posterior lobes. • This gland was once believed to be the main controlling gland of the body. • The pituitary gland then makes hormones of its own in answer to the body's needs. Pituitary gland
  • 6.  the "third eye" by ancient people.  The pineal does contain a complete map of the visual field of the eyes, and it plays several significant roles in human functioning.  center for the production of the hormone melatonin.  regulates daily body rhythms, most notably the day/night cycle, prevents jet lag, is implicated in seasonal affective disorder, coordinates fertility, and allows for deep restful sleep patterns  Connect to the brain and nerves system through a complex network of bidirectionnel links. Pineal gland
  • 7.  Shaped like a butterfly.  and usually weighs less than one ounce.  The thyroid cartilage covers the larynx and produces the prominence on the neck known as the "Adam's Apple".  Controls the rate at which the body produces energy from nutrients.  If the body does not get enough iodine, the thyroid gland cannot produce a proper amount of hormones for this conversion process. Thyroid gland
  • 8.  small endocrine glands in the neck that produce parathyroid hormone.  Humans have four parathyroid glands.  located in variable manner on the posterior surface of the thyroid gland, or, in rare cases, within the thyroid gland itself or in the chest (mediastinum) or even the thymus.  control the amount of calcium in the blood and within the bones. Parathyroid gland
  • 9.  Forms in a part of the immune system.  It is situated in the upper part of the chest.  made up of two lobes that join in front of  function is to transform lymphocytes (white blood cells developed in the bone marrow) into T-cells (cells developed in the thymus)  The thymus enlarges from about the 12th week of gestation until puberty.  transported to various lymph glands.  play an important part in fighting infections and disease. Thymus gland
  • 10.  found on top of both of the kidneys.  The center of the adrenal consists of the medulla which produces epinephrine and norepinephrine. Adrenal gland
  • 11. • pancreas has two main functions: • to produce pancreatic endocrine hormones, which help regulate many aspects of our metabolism • to produce pancreatic digestive enzymes Pancreas
  • 12. o produce a female hormone and it called as estrogen. o store female sex cells, or “ova.” Ovary
  • 13. Testes is male gonads. Suspended within a sac of skin called the Scromtum. It is composed of seminiferous tubles. It have two main function:  Formation, Developmet and excretion of sperm.  The secretion of testosteron. Testes
  • 14. Conclusion Hormones are Regulated by the Glands Growth Development Reproduction Metabolic Rate Fluid Balance Blood Homeostasis And Coping with stress Endocrine system is the system of glands that produce endocrine secretions that help to control bodily metabolic activity
