Endocrine System Review Sheet
Biology exam
Endocrine system:
Hormones: chemical messengers that coordinate the body’s activates. Substances secreted by cells that act to regulate the activity of other cells in the body. They are part of the endocrine system and they are slow acting but have a longer affect than neurotransmitters.
Functions:
* regulate growth, development, behavior, and reproduction. * Maintain homeostasis * Regulate metabolism and water and mineral balance * Respond to external stimuli * Exocrine glands: secrete substances ( water/enzymes/ mucus) through tube like ducts. * The ducts transport the substances to specific locations inside and outside the body.
Ex. Liver, sweat glands, mucus glands, salivary glands, other digestive glands
The endocrine system consists of:
* Endocrine glands: ductless organs …show more content…
* Lymphocytes can provide specific defense because they recognize foreign invaders. * How lymphocytes recognize pathogens: * Has unique receptor proteins all over the surface of its cell membrane * These receptor proteins recognize and bind to antigens that match their three-dimensional shape * All of the receptors on an individual lymphocyte are the same shape or type and thus bind to the same type of antigens. * Body makes a lot of different lymphocytes, with different receptors. * Antigen: any substance that the immune system can recognize and react with.
-pathogens or -parts of pathogens, -bacterial toxins, -insect venom, -pollen
-any molecule that is not a natural part of an individual’s body, such as that from transplanted tissue or transfused blood of an incompatible type, can act as a foreign antigen
Antigens cover pathogens.
* Antigens cause lymphocytes to react.
Lymphocyte recognizes antigen > binds to antigen > specific attack.
This reaction is called immune response.
