Covers: endocrine system and nervous system control the body in different way
pituitary gland as "master gland"
target cells, receptors
thyroid -> thyroxin (widespread receptors)
pituitary -> follicle stimulating hormone (receptors focused in one area)
chemical structure of hormones
water soluble hormones - receptors on membrane
lipid soluble hormones - receptors inside cell
a hormone increases or decreases some functions
pancreas -> insulin -> lowers blood sugar
pancreas -> glucagon -> increases blood sugar
hypersecretion and hyposecretion of hormones leads to illnesses,
hormone cascades
hypothalamic-pituitary-adrenal (HPA) axis:
hypothalamus -> CRH ->
pituitary gland -> ACTH ->
adrenal cortex -> glucocorticoids and mineralocorticoids
-> fight or flight response -> hypothalamus
Animation about diabetes and the body with subtitles and British Sign Language

Covers: digesting carbohydrates yields glucose
body detects rising glucose -> pancreas releases insulin -> insulin helps us get energy from food
insulin helps glucose enter cells
liver releases stored glucose
type 1 diabetes: autoimmune response, no insulin produced, symptoms/complications of type 1 diabetes, type 2 diabetes: not enough insulin or insulin doesn't work properly, symptoms/complications of type 2 diabetes

Covers:
glucose = fuel that powers cells
blood glucose regulation
increase glucose by: food, synthesis, storage
decrease glucose by: transport glucose into cells for energy or storage
insulin released when blood glucose is high
effects of insulin
diabetes mellitus
symptoms/complications of diabetes
glucose movement through kidneys
type 1 diabetes: islets of Langerhans, beta cells, triggers that lead to diabetes, ketone bodies, diabetic ketoacidosis
type 2 diabetes: risk factors, insulin resistance
diabetes medications/treatment: insulin treatment, diabetic drugs, metformin
diabetes prevention
global number of cases

Covers: case study of person with increased energy levels, thyroid, homeostasis, Grave's disease, hypethyroidism, HPA axis, hypothalamus, pituitary, adrenal glands, HPT axis, hypothalamus, pituitary, thyroid, cold temperature --> hypothalamic neurons release TRH (a tropic hormone) --> anterior pituitary --> TSH --> thyroid hormone --> cells "burn" more glucose --> increase ATP production --> increase temperature, other affects of thyroid hormone, negative feedback, autoimmune dysfunction, thyroid glands confused by antibodies

Covers: hypothalamic-pituitary-adrenal (HPA) axis, role in stress response, hypothalamus controls release of hormones from pituitary gland, hormones from pituitary travel to adrenal glands, hypothalamus --> CRH --> pituitary gland --> ACTH --> adrenal cortex --> cortisol --> effects that help body deal with stress --> negative feedback system - high cortisol levels suppress hypothalamus
