Study Notes
The Endocrine System
- The endocrine system is made up of glands that release hormones into the bloodstream
- Hormones affect almost all cells, organs, and bodily functions
- Hormones regulate growth, development, metabolism, and reproductive processes
- Endocrine glands secrete hormones
- Hormones travel throughout the body
- Hormones trigger a response in target organs
- Endocrine responses can take a few hours or even weeks
Endocrine Glands and Their Hormones
- The endocrine system consists of glands that release hormones into the body
- Each gland has specific functions, locations, and hormones produced
- Pituitary gland: Located at the base of the brain; stimulates growth, controls functions of other glands; releases oxytocin, vasopressin, growth hormone, ACTH, prolactin, FSH
- Thyroid gland: Located below the voice box; regulates body metabolism and calcium storage in bones; releases thyroxine, calcitonin
- Parathyroid gland: Located in the neck; controls calcium levels and normalizes bone growth; releases parathyroid hormone
- Thymus gland: Located in front of the heart; enables the body to produce certain antibodies; releases thymosin
- Adrenal glands: Located on top of the kidneys; prepares the body for action by controlling heart rate, breathing; releases adrenaline
- Pancreas: Located between the kidneys; regulates blood sugar levels; releases insulin, glucagon
- Reproductive glands (Testes): Located in the lower abdomen of males; controls male characteristics, maturation; releases androgens, testosterone, estrogen
- Reproductive glands (Ovaries): Located in the lower abdomen of females; influences female traits, supports reproductive function; releases progesterone
Effects of Hormones on the Body
- Hormones coordinate body processes
- Hormones regulate organ, tissue, and cell function
- Hormones impact growth, appearance, emotions and reproductive functions
- Hormones have both short-term and long-term effects
- Hormonal changes occur during puberty
- Hormonal imbalance can cause health problems
The Reproductive System
- The reproductive system is controlled by hormones
- Reproduction is essential for species survival
- Human reproduction is complex
- Males and females have different reproductive systems, but they use similar structures sometimes
- Hormones regulate reproductive functions in both males and females.
Male Reproductive System Parts and Functions
- Testes: Produce sperm
- Scrotum: Holds the testes
- Penis: Deposits sperm
- Vas deferens/Urethra: Carry sperm
- Glands: Provide liquid for sperm
Female Reproductive System Parts and Functions
- Ovaries: Produce egg cells
- Oviducts (Fallopian tubes): Passageway for eggs
- Uterus: Site of implantation and fetal development
- Vagina: Receives the penis
- Hormones regulate reproductive functions in both males and females
The Menstrual Cycle
- The monthly cycle in females
- Ovaries release eggs
- Hormones control egg release, uterine lining changes
- Cycle involves maturation of the egg, releasing of the mature egg, and uterine lining preparation.
- If the egg is not fertilized, the uterine lining is shed.
