Focus Question: What are the structures and functions of the male and female reproductive systems?.

Vocabulary. Review Vocabulary hypothalamus: portion of the brain that connects the endocrine and nervous systems; controls the pituitary gland.

Identify the main functions of the human reproductive system as: to reproduce and continue the existence of humans, to produce the next generations, and to produce egg and sperm cells Identify the structures and their functions of the male reproductive systems to include testes, epididymis, scrotum, seminal vesicle, vas deferens, and prostate gland Explain that the origin of semen includes the seminal vesicles, the prostate gland and the bulbourethral gland Explain the importance of substances found in semen Sequence the structures which sperm cells travel through as they exit the body Identify the structures and their functions of the female reproductive systems to include ovaries, uterus, vagina, and oviduct Describe the structure of the sperm cell and the egg cell Describe the effects of male and female hormones on the development of secondary characteristics in males and females Explain how hormones regulate the male reproductive system to include testosterone, GnRH, FSH and LH Explain how hormones regulate the female reproductive system to include: estrogen, progesteron, LH and FSH Explain the major phases that take place during the menstrual cycle Describe the negative feedback mechanism of menstruation and the positive feedback mechanism of ovulation Describe the negative feedback mechanism used to regulate the male reproductive system Define the terms gamete and gonad Define meiosis as the process during which gametes are produced with half the chromosome number.

Reproduction is necessary to ensure the continuation of a species. Main things involved in reproduction are the organs, glands, and hormones of the male and female reproductive systems The processes that happen in reproduction are union of an egg cell and a sperm cell development of the fetus the birth of an infant..

Male reproductive cells are called sperm. Sperms develop in seminiferous tubules of the testes. These tubules produce 100–200 million sperm each day..

EPIDIDYMIS- a structure located on top of each testis. Maturation and storage of sperm..

SEMINAL VESICLES contribute over half of the semen It secrete sugar (provides energy), other nutrients, proteins, and enzymes for the sperm..

Anterior pituitary Capillary FSH and LH released to general circulation Hypothalamus produces GnRH Capillary Posterior pituitary.

Negative feedback system starts with the hypothalamus. Increased levels of testosterone in the blood are detected by cells in the hypothalamus and anterior pituitary, and the production of LH and FSH is decreased. When testosterone levels in the blood drop, the body responds by making more LH and FSH..

OVARY - Site of production of egg cell/ovum. OVIDUCT - tube which connect ovary to uterus through which the egg travel.

Egg Corpus Egg Follicle Egg develops. Each ovary is about the size of an almond. each ovary contains immature eggs called OOCYTES. Approximately once every 28 days, oocyte development is stimulated to form EGG CELL/ OVUM. The ovum is surrounded by FOLLICLE CELLS that provide protection and nourishment..

Female hormones. Ovaries produce 2 steroid hormones- ESTROGEN and PROGESTERONE Anterior pituitary produce FSH and LH which influence the level of estrogen and progesterone in a negative feedback loop..

Sex Cell Production. Through meiosis, cells in the testes or ovaries gives rise to sex cells called gametes. Male gametes are sperm, produced by spermatocytes. Sperm produced daily when puberty starts and continue throughout his life..

Sex Cell Production. Egg production differs from sperm production..

What condition is necessary in order for the seminiferous tubules in the testes to produce sperm cells?.

The two meiotic divisions of egg production yield how many eggs?.

Which hormone influences the development of male secondary sex characteristics at puberty?.

Which hormones secreted by the anterior pituitary gland regulate the levels of testosterone in males and estrogen in females?.

Testosterone and progesterone are the female hormones produced in the ovaries. True False.

The Menstrual Cycle. The length of the menstrual cycle can vary, but it typically lasts about 28 days. The cycle can be divided into three phases: Flow phase Follicular phase Luteal phase.

The Menstrual Cycle. Flow phase Follicular phase 6-14 Luteal phase 15-28 Days Hormone levels FSH Estrogen Progesterone Ovarian activity Endometrium.

Endometrium. Endometrium. Lining of uterus is called endometrium. It is the site of implantation (attachment of embryo) It has good supply of blood vessels which give the embryo nutrients and oxygen..

Day 1 – beginning of menstrual flow- Shedding of blood, tissue fluid, mucus, epithelial cells tear from endometrium Bleeding occurs due to tearing of endometrium and rupturing of blood vessels. Day 5 – Repair of endometrial lining, cycle continues.

2. Follicular phase. Changes in ovaries occur Low estrogen level at beginning of cycle and increased level of FSH and LH which stimulates maturation of few follicle cells Developing follicle cells produce estrogen and less progesterone which keep FSH and LH levels low (negative feedback). Only one follicle containing egg matured fully. Day- 14- high amount of LH release by anterior pituitary – LH surge- cause the rupture of follicle and OVULATION occurs..

Which hormone causes ovulation to occur at the end of the follicular phase?.

Luteal phase. After ovulation, the cells of the follicle changed into a structure called the CORPUS LUTEUM Corpus luteum produces high amounts of progesterone and some estrogen, which reduce the levels of LH and FSH (negative feedback) Toward the end of the cycle, the corpus luteum breaks down, and no production of progesterone and estrogen. This results in a rapid decrease in progesterone and estrogen levels which triggers detachment of the endometrium, and the flow phase of a new menstrual cycle will begin..

If the egg is fertilized, a different chain of events occurs, and a new menstrual cycle does not begin. The progesterone levels remain high and increase the blood supply to the endometrium. The corpus luteum does not degenerate and hormone levels do not drop. The endometrium accumulates lipids and begins secreting a fluid rich in nutrients for the developing embryo.

What triggers a new menstrual cycle and the beginning of menstrual flow?.

What prevents the menstrual cycle from continuing once an egg has been fertilized?.
