Reproductive system Flashcards
Respiratory system: 2 portions
- Conducting portion
- Respiratory portion
Conducting portion of respiratory system: Components
- Nose
- Naval cavity
- Pharynx
- Larynx
- Trachea
- Bronchi
Respiratory portion of respiratory system: Components
- Lungs
Respiratory system: Functions
- Primary responsibility for the exchange of the gases - oxygen and carbon dioxide - between the atmospheric air, blood, and tissues
- Also has an important role in regulating body fluid pH
- System can be divided into conducting portion and the respiratory portion
Nasal cavity: Components
- Nose
- Nasal cavity
- External naris (nostril)
- Olfactory epithelium
- Nasal meatuses
- Internal naris
Nasal cavity: Functions
- The respiratory epithelium filters, warms, and moistens inspired air
- The conducting portion of the respiratory system moves air into the lungs
- Contains chemoreceptors for the sense of smell
Pharynx: Components
- Pharyngeal tonsil
- Nasopharynx
- Oropharynx
- Epiglottis
- Hyoid bone
- Laryngopharynx
- Esophagus
- Trachea
Pharynx: Functions
- Part of conducting portion of the system providing a passageway for air
- Provides a resonating chamber for speech sounds
Larynx: Components
- Hyoid bone
- Epiglottis
- Ventricular fold (false vocal cord)
- Vocal fold (true vocal cord)
- Trachea
Larynx: Functions
- A connecting passageway between the pharynx and the trachea
- Epiglottis works as a “trap door” to prevent food and liquid from entering inferior airways
- Vocal cords vibrate to produce sound
Trachea and Bronchi: Components
- Larynx
- Trachea
- Primary bronchi
- Secondary bronchi
- Tertiary bronchi
- Bronchioles
- Terminal bronchioles
- Diaphragm
Trachea and bronchi: Function
- Trachea is a passageway for air between the larynx and where it branches into the bronchi in the lungs
- The bronchial tree continues to branch in the lungs to ultimately provide for passage of air to the alveolar ducts
Lungs: Functions
- The alveolus is the site of gas exchange - the intake of oxygen for delivery to cells and the elimination of carbon dioxide produced by cells
- The bronchiole regulates the flow of air to the alevoli
Lungs: Components
- Pulmonary venule
- Pulmonary arteriole
- Pulmonary (alveolar) capillary
- Alveolus
- Alveolar ducts
- Alveolar sac
- Bronchiole
- Right lung
- Middle lobe
- Superior lobe
- Inferior lobe
- Left lung
Male reproductive system: Functions
- Produces, stores and transports sperm for fertilization of female oocyte
- Produces the hormone testosterone in the testes
Male reproductive system: Components
- Epididymis
- Testes
- Ductus (vas) deferens
- Penis
Female reproductive system: Functions
- Ovary produces and transports oocytes (immature eggs) for fertilization by male sperm
- Ovary provides the hormones progesterone and estrogen
- Uterus provides for development of fetus during pregnancy and delivery of baby during labor and childbirth
- Breast synthesizes, secretes and ejects milk for newborn
The female reproductive system: Components
- Uterus
- Uterine (fallopian) tube
- Ovary
- Cervix
- Vagina
- Mammary gland
- Nipple
Uterus: Components
- Uterine (fallopian) tubes
- Uterus
- Vagina
- Endometrium
- Myometrium
- Perimetrium
Uterus: Functions
- Site of implantation of fertilized ovum (mature egg)
- Site of development during pregnancy and labor
- Site of menstration
- Passageway for sperm to fertilize oocytes
Fallopian tubes: Components
- Uterine (fallopian) tubes
- Fimbriae of uterine tube
Fallopian tubes: Functions
- Transports oocytes from ovaries to the uterus
- Usual site of fertilization of female oocyte by male sperm
- Transports fertilized ovum to uterus for implantation
Ovaries: Components
- Ovaries
- Uterine (Fallopian) tubes
- Uterus
Ovaries: Functions
- Oocytes are formed and developed and transported to uterine tubes
- Produces and secretes hormones - estrogen, progesterone, inhibin, and relaxin
Mammary gland: Components
- Nipple
- Mammary duct
- Lactiferous duct
- Lobule containing alveoli
Mammary gland: Functions
- Synthesizes, secretes and ejects milk for a newborn
Epididymis: Composition
- Spermatic cord
- Ductus (vas) deferens
- Epididymis
Epididymis: Functions
- Epididymis is site of sperm maturation
- Ductus deferens transports and stores sperm
Testes: Components
- Testicular blood vessels, Lymphatic vessels, and nerves
- Testis
Testes: Functions
- Produces sperm
- Produces testosterone
Epididymis and Ductus (vas) deferens: Components
- Spermatic cord
- Ductus (van) deferens
- Epididymis
Epididymis and Ductus (vas) deferens: Functions
- Epididymis is site of sperm maturation
- Ductus deferens transports and stores sperm
Penis: Composition
- Ejaculatory ducts
- Internal urethral orifice
- External urethral orifice
- Urethra
- Penis
- Glans penis
Penis: Functions
- The passageway for the ejaculation of semen through the urethra
