Endocrine system

• Responses in the endocrine system are slower than those in the nervous system
• Endocrine systems have organs known as glands. Glands secret chemical messengers known as hormones
• hormones are released into the blood stream ( transport)
• organs -> glands -> hormones -> bloodstream
• Hormones attach to specific receptors on the cell. Receptors have specific shapes that match up with a specific hormone
• Receptors are called glycoproteins
• Hormones will only work on organs they are specific for
• Cells on organs have receptors on their surface
• Once a hormone binds to the receptor, this causes the organ to respond to the stimulus
• central nervous system (hypothalamus
• The organs involved in the endocrine system are pancreas, hypothalamus, pituitary gland, adrenal gland, ovary, testes

  
• Diabetes is when the pancreas can't produce insulin or can't use it
• insulin helps carry glucose into cells and is produced by the pancreas
• Alpha cells found in the pancreas produce glucagon
