Reproduction And Heredity Flashcards
Secrete chemicals through ducts to outside of body(External)
Exocrine
Secrete hormones directly into blood stream(no ducts to exit) that signal changes in other parts of the body(Internal)
Endocrine
Chemical substance, or message, released by an endocrine gland that has a specific function in the body
Hormone
Period of sexual development during which a person becomes sexually mature and physically able to reproduce
Puberty
How dose Puberty start?
1produce Sex Hormones
- Produce/Store sperm
- Deliver sperm to female reproductive system
Sexual organ through which sperm leave the body. The tip is covered with with loose skin, called the foreskin. Foreskin removal=Circumcision
Penis
Male reproductive glands (2functions=production of Testosterone and sperm)
Testes
Reproductive sells(male)
Sperm
Sperm cell joins with an egg
Fertilization
Semen
Mixture of sperm cells and fluids
Ejaculation
Ejection of semen from the penis
Female reproductive system
- Produce Sex Hormones
- Produce Eggs
- Provide a nourishing environment in which a fertilization egg can develop into a baby
Reproductive cells/eggs(in females)
Ova
Reproductive glands in which eggs are produced (2 Functions=produce hormones estrogen and progesterone and release mature egg sells)
Ovaries
Activities certain physical changes at puberty
Estrogen
Activities changes to a woman’s reproductive system before and during pregnancy
Progesterone
One of the ovaries releases a ripened egg about once every month
Ovulation
Passages that carry eggs away from ovaries
Fallopian Tubes
Hollow, muscular organ where egg can grow and develop
Uterus
Hollow, muscular passage leading from the uterus to the outside of the body
Vagina
Process by which a female produces one mature egg each month
Menstrual Cycle
On average, Menstrual Cycles usually last about_______days
28
Factors affecting menstrual cycle
- Diet
- Stress
- Exercise
- Weight gain/loss
Ovaries slow down hormone production and no longer release eggs
Menopause
Daily washing
Cleanliness
Eliminate infections, diseases, etc. until God approves
Sexual Abstinence
Learn how to monitor for medical problems
Self exams
Yearly check-ups should be done by a professional
Medical Check-ups
Endocrine System
Hypothalamus, pituitary gland, thymus gland, adrenal gland, thyroid gland, parathyroid glands, pancreas, ovaries, testes
Filled in blanks
Self abuse, blinded, sin, destroying, brain
Causes of self ‘pleasure’
Brain weekend, head decay, insanity, memory loss, liver/kidney damage, headache
Hypothalamus
Links nervous system, endocrine system, and controls some pituitary gland functions
Pituitary gland
Controls other endocrine glands…
Thymus gland
Hormones released by the thymus gland
Adrenal glands
Triggers the body to respond in sudden stress
Thyroid gland
Regulates overall metabolic rate and controls calcium
Parathyroid glands
4 parathyroid glands regulate calcium and phosphorus(tooth formation)
Pancreas
Behind the stomach, controls sugar levels in the blood
Ovaries
He male reproductive glands(egg maturation and control)
Testes
Male reproductive glands (regulates sperm production)
Sperm Pathway>travels through the vas deferents to seminal vesicles>Produced in the testes/mature-stored in epididymis>prostates gland protects the sperm with fluid>seminal vesicles add fluids produce energy for the sperm>bulbourethral glands fluid protecting the perm from the urethra
