Endocrine System 16.1-16.3 Flashcards
how does the endocrine system act with the nervous system
acts with the nervous system to coordinate and integrate activity of body cells.
- influences metabolic activities via hormones transported in blood responses slower but longer lasting than nervous system responses
whats the 5 things the endocrine system controls and integrates
1- Reproduction
2- growth and development
3- maintence of electrolyre,water, and nutrient balance of blood
4- regulation of cellular metabolism and energy balance
5- Mobilization of body defenses
exocrine glands
produce nonhormonal substances (examples:sweat, saliva) have ducts to carry secretion to membrane surface
Endocrine glands function
produces hormones, lacks ducts
list some endocrine glands
pituitary, thyroid, parathyroid, adrenal, pineal glands
whats a neuroendocrine organ
hypothalamus
name the endocrine organs that have both endocrine and exocrine functions
pancreas, gonads, placenta
what are other tissues and organs that produce hormones
adipose cells, thymus, cells in walls of small intestine, stomach, kidneys, and hear
whats the three endocrine chemical messengers of endocrine system
hormones
autocrines
paracrines
hormones
long-distance chemical signals; tavel in blood or lyph
Autocrine
chemicals that exert effects on same cells that secret them
paracrines
locally acting chemicals that affect cells other than those that secrete them
what are autocrines and paracrines
are local chemical messenger; not considered part of the endocrine system
whats the two main classes of hormones
Amino acid-based hormones
steroids
Amino acid-based hormoes
amino acid derivatives, peptides and proteins
