The aim of the female reproductive system is to produce mature oocytes which match with the male spermatocyte to create offspring. Fertilisation most commonly occurs in the fallopian tubes‚ though this can also occur later in a female’s menstrual cycle if the egg has already moved down into the uterus‚ though there is a higher chance of miscarriage as the lining of the womb may continue to shed. The external female reproduction features have two functions; to allow insemination and to also protect

MALE REPRODUCTION MALE REPRODUCTIVE PHYSIOLOGY Testis - 2 compartments: interstitial tissue containing the Leydig cells that synthesize and secrete testosterone and the seminiferous tubules that produce spermatozoa and contain Sertoli cells Leydig cells and testosterone synthesis - Leydig cells mainly produce testosterone - T is a prohormone for synthesis of estradiol (vs. aromatase) and DHT (via. 5-alpha-reductase) - many effects of T are mediated via estradiol (esp in

Anatomy of the Female Reproductive System The reproductive role of the female is far more complex than that of a male. Not only must she produce gametes‚ but her body must prepare to nurture a developing embryo for a period of approximately nine months. Ovaries‚ the female gonads‚ are the primary reproductive organs of a female‚ and like the male testes‚ ovaries serve a dual purpose: They produce the female gametes (ova) and sex hormones‚ the estrogens * and progesterone (pro-ges′tĕ-rōn). The

Female and male pigs share many similarities externally‚ but internally they are quite different. Just as the male does not have an external penis‚ and the scrotum is not well developed until sexual maturity‚ the entrance to the female’s vagina is hidden beneath the tail. In the female reproductive system the primary reproductive organs of the female is the ovaries. They are small kidney- shaped organs that usually cover the fallopian tubes. Next to the ovary lies the funiculum (funnel shaped)

Ovarian Cycle Follicular Phase ↓ Est‚ ↓ Prog → ___ FSH release FSH → granulosa cells secrete ____ The major follicle will secrete the most estrogen and inhibin which will have a negative inhibition on FSH‚ LH and GnRH release (this will allow a greater chance of only one follicle maturing) When Est levels are highest → will switch to a positive feedback and stimulates ↑↑ secretion of LH‚ FSH and GnRH. Meanwhile‚ the follicle is also secreting a little Prog which stimulates GnRH and ↑ LH release

Biological Systems Paper Lisa J Felton PSYCH/626 April 14‚ 2014 Taleshia Chandler Biological Systems Paper There are numerous articles written to explain the issues that can occur in the lungs and the respiratory system from smoking however there seem to be other issues that need to be looked at as well. While we know that smoking can cause a great deal of damage to the lungs and can contribute to the development of COPD (Chronic Obstruction Pulmonary Disease) (Kool & Reneman‚ 1993)‚ there are other

The respiratory system is composed of the nasal cavity‚ nostril‚ oral cavity‚ pharynx‚ larynx‚ trachea‚ carina of trachea‚ right main bronchus‚ right lung‚ left main bronchus‚ left lung‚ and diaphragm. These major organs collectively work together to give the body oxygen and eliminate carbon dioxide as we breathe. In order for the respiratory system to be fully capable of function‚ four procedures (pulmonary ventilation‚ external respiration‚ transport of respiratory gases‚ internal respiration)
