Testes
In males, the testes, located in the scrotum, secrete hormones called androgens; the most important of which is testosterone
Ovaries
In females, the ovaries, located on both sides of the uterus, produce estrogen and progesterone as well as eggs.
- Hypothalamus
The hypothalamus is located in the lower central part of the brain. This part of the brain is important in regulation of satiety, metabolism, and body temperature. In addition, it secretes hormones that stimulate or suppress the release of hormones in the pituitary gland.
What is Endocrine system?
The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs.
-
Exocrine glands are glands that produce and secrete substances onto an epithelial surface by way of a duct.
sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous.
to regulate body temperature, lubricate, nurture newborns (lactation), aid in digestion, and aid in reproduction.
Exocrine Gland Structure
ductal portion
The tubular duct can be simple in structure (unbranched) or complex with many duct branches. The tubular duct can also be observed in a simple coiled structure.
glandular portion
called acinus or acini (plural)) or elongated cluster of cells that produce the secreted substance. There are different types of cells found in the glandular portion depending on the substance secreted. Some common cell types include serous cells (protein excretion) and mucous cells (mucus/fluid excretion).
