THE ENDOCRINE SYSTEM - Regulates long-term changes in the body
such as growth and development (controls many of your bodys
functions) - Endocrine glands produce and release chemical
substances that signal changes in other parts of the body -
Hormones chemical substances produced by an endocrine gland
FUNCTIONS OF GLANDS: - Hypothalamus - body temperature and
sleep/hunger, water levels - Pituitary growth, reproduction,
metabolism (master gland) - Thyroid, Parathyroid, thymus, adrenal,
pancreas, ovaries, testes - Puberty the period of sexual
development during which a person becomes sexually mature and
physically able to reproduce
Slide 3
THE MALE REPRODUCTIVE SYSTEM Structure and Function: - Sperm
male reproductive cells - Fertilization process where a sperm cell
may join with an egg to produce a baby - Testes 2 ovalshaped male
reproductive cells stored in the Scrotum - Production of
testosterone - Production of sperm - Penis the external sexual
organ through which sperm leave the body Sperm Production: hormones
in brain signal two hormones (LH and FSH) to make testosterone and
Semen (mixture of sperm cells and fluids from other glands) -
Ejaculation ejection of semen from the penis
Slide 4
Cleanliness Sexual Abstinence Protection from Trauma Self-Exams
Medical Checkups - Infertility the condition of being unable to
reproduce KEEPING HEALTHY
Slide 5
THE FEMALE REPRODUCTIVE SYSTEM Structure and Function: - Ova
female reproduction cell - Ovaries glands in which eggs are
produced and stored Estrogen hormone that activates certain
physical changes (breast development and maturation of eggsk)
Progesterone activates changes to a womans reproductive system
before and during pregnancy Ovulation release of a ripened egg once
a month - Fallopian tubes passageways that carry eggs away from the
ovaries (where fertilization usually takes place) - Uterus hollow,
muscular, pear-shaped organ where a fertilized egg can develop and
grow - Vagina birth canal, hollow muscular passage leading from the
uterus to the outside of the body
Slide 6
THE MENSTRUAL CYCLE - an ovary releases a mature egg. The egg
travels to the uterus. If the egg is not fertilized, the uterine
lining is shed and a new cycle begins
Slide 7
THE MENSTRUAL CYCLE
Slide 8
KEEPING HEALTHY - Cleanliness - Sexual Abstinence - Prompt
Treatment for Infections - Self-Exams - Medical Checkups - Pap
smear - Mammogram - Ovarian cysts - Endometriosis -
Infertility
Slide 9
HEREDITY - the passing on, or transmission, of biological
traits from parent to child - chromosomes - genes Heredity
information passes from one generation to the next through genes
contained on the two sets of chromosomes that a person receives
from their parents Genetic Disorder caused by the inheritance of an
abnormal gene or chromosome For most diseases, your environment and
your behavior affect your risk as much as or even more than your
genes. - Genetic Testing - Gene Therapy
