endocrine system coordinates with _ to integrate activity of body cells
nervous system
_ glands produce hormones but have no ducts
endocrine
_ hormones involve amino acid derivatives, peptides, and proteins
amino acid-based
_ hormones are synthesized from cholesterol; gonadal and adrenocortical hromones
steroid
_ alter plasma membrane permeability, stimulate enzyme synthesis, induce secretion, stimulate mitosis
hormones
hormone action depends on _ nature and _ location
chemical; receptor
_ hormones have extracellular [plasma membrane] receptors; act via G protein second messenger
water-soluble
_ hormones have intracellular receptors that directly activate genes
lipid-soluble
second messengers include _ and _
cAMP; PIP2-Ca
_ signs are polyuria, polydipsia, polyphagia
diabetes mellitus
type 1 DM = _ of insulin; type 2 DM = _ of insulin
hyposecretion; hypoactivity
pituitary gland is connected to hypothalamus via _
infundibulum
_ is directly involved with metabolism (glucose sparing), and indirectly promotes growth
growth hormone (GH)
_ involves gamete (egg-sperm) production
follicle-stimulating hormone (FSH)
_ involves gonadal hormone production which mature egg follicles, triggers ovulation, triggers progesterone-estrogen release or trigger testosterone release
luteinizing hormone (LH)
_ stimulates uterine contraction, milk ejection
oxytocin
_ stimulates water reabsorption in kidneys
antidiuretic hormone (ADH)
_ is most active during pre-pubescence to allow T cells to mature
thymus
blood pH is between 7.35-7.45 so it is _
slightly alkaline
_ is composed of plasma and formed elements (RBC, WBC, platelets)
blood
_ (biconcave disks and no organelles) huge surface area relative to volume for gas exchange; respiratory gas transport
erythrocytes (RBC)
_ (less than 1% blood) involve defense against disease
leukocytes (WBC)
_ (cell fragments of megakaryotes) are involved in blood clotting
platelets
blood type _ has A antigen and B antibody
