Zona glomerulosa
Adrenal Cortex: Aldosterone
Zona fasciculata
Adrenal Cortex: Cortisol
Zona reticularis
Adrenal Cortex: Androgens
Hypothalamus
-Couples nervous system and endocrine system
-Regulate Pituitary gland
-Produce tropic hormones
Anterior Pituitary
-Stimulates the growth and development of target tissues
-Synthesizes and secretes seven hormones FLATPIG
Posterior Pituitary
-Stores and releases two hormones that are not synthesized in pituitary
-Oxytocin (OT) uterine contractions
-Antidiuretic hormone (ADH) fluid balance
Thyroid Glands
-Increases the metabolic rate of target cells
-Calcium Homeostasis
-Follicle cells of the thyroid gland synthesize thyroglobulin
Hyperthyroidism
Overactive thyroid gland
-Thyroid Hormone
-T3 and T4
-Inhibit TSH via negative feedback
Hypothyroidism
-Thyroid gland does not make enough hormone
Parathyroid gland
Produce parathyroid hormone
-Calcium homeostasis
Adrenal Glands
Adrenal Cortex
Adrenal Medulla
Pancreas
Endocrine (Islet of Langerhans)
Exocrine (Acini cells)
glucagon
A cells of islet of langerhans secrete ---
insulin
B cells of islet of langerhans secrete ---
acini cells
secrete outside through pancreatic duct
ovaries
Produce Estrogen and Progesterone
Testes
Testosterone
alimentary canal
continuous tube that extends from the mouth to the anus
mechanical digestion
Breaking food into smaller pieces
Chemical Digestion
Enzymatic breakdown of large molecules into smaller ones
Peristalsis
A progression of coordinated contractions and relaxations of the circular and longitudinal layers of the muscularis, pushes bolus down to stomach
Segmentation
Localized
Mixing contractions that occur in portions of intestine
-Distended by a large volume of chyme
Salivary glands
Function:
-Secrete saliva
-Lubricate Food
-Dissolve foods
-Begin chemical breakdown
Pancreas
Glucose regulation
Buffer stomach acid
Chemical digestion: pancreatic amlyase, pancreatic lipase
Liver and gallbladder
Make bile: emulsifies lipids
Deliver to gallbladder- storage of bile
Peritoneum
Largest serous membrane in the body
-Parietal peritoneum - peritoneal fluid
-Visceral peritoneum
