Endocrine System

• Endocrine system - is responsible for the changes that you see or feel in your body. regulates, coordinates, and controls growth and development
• Endocrine glands - organs of edocrine system that produce and secretes (releases) hormones. Its effects takes longer time to process unlike nervous system.
• Hormones - Chemical messengers that are secreted from glands into blood stream and affect cells in other parts of the body.
• Target cells - hormonrd that work on certain cells
• Receptor - part of target cells that "recognize" the hormones and allow them to influence that cells
• External Stimuli - by way of nerves from sensory organs in the nervous system
• Internal stimuli - by way of nerves and other hormones from inside the body
• nerve cells travel throught neurons
• hormones travel through blood stream
• Pituary - also called as master's gland and located at the base of the brain
• pituary - regulates all other endocrine glands and releases growth hormones
• thyroid - gland that is located below the voice box/trachea that regulates metabolism, body heat, and bone growth
• thyroid - cause storage of calcium in bones
• Parathyroid -gland that is located in the neck/back of thyroid, regulates use of calcium and phosphorus
• parathyroid - controls calcium level and normalizes bone growth
• hypothalamus - located above pituary/brain and links nervous system to endocrine system,
• adrenal - located on top of kidneys, regulates response through emergency and stressful situations
• adrenal - regulates metabolism, blood pressure, and salt balance, and prepares body for action
• pancreas - located between kidneys/below of stomach and regulates blood sugar levels
• ovaries - located at lower abdomen, regulates production of eggs, influence female traits
• testes - located at lower abdomen, regulates production of sperms and controls maturation and male characteristics
• thymus - located infront of the heart, regulates parts of the immune system, produces body's antibodies
• pineal gland - modulates sleep patterns and produces melatonin
• placenta - for keeping the baby safe in times of pregnancy
• Hypothalamus - antidiuretic hormone
• hypothalamus - oxytocin
• what is the target organ of antidiuretic hormone?

  kidney
• what is the target organ of oxytocin?

  uterus
• What hormone regulates water reabsorption of the cells?

  antidiuretic hormone
• what hormone is for the contraction of uterus in giving birth?

  oxytocin
• Pituary - growth hormone
• pituary - thyroid stimulating hormone
• pituary - adrenocorticotropic hormone
• pituary - follicle stimulating hormone
• pituary - luteinizing hormone
• what is the target organ of growth hormone?
