Reproductive system Flashcards
1
Q
Respiratory system: 2 portions
A
- Conducting portion
- Respiratory portion
2
Q
Conducting portion of respiratory system: Components
A
- Nose
- Naval cavity
- Pharynx
- Larynx
- Trachea
- Bronchi
3
Q
Respiratory portion of respiratory system: Components
A
- Lungs
4
Q
Respiratory system: Functions
A
- 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
5
Q
Nasal cavity: Components
A
- Nose
- Nasal cavity
- External naris (nostril)
- Olfactory epithelium
- Nasal meatuses
- Internal naris
6
Q
Nasal cavity: Functions
A
- 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
7
Q
Pharynx: Components
A
- Pharyngeal tonsil
- Nasopharynx
- Oropharynx
- Epiglottis
- Hyoid bone
- Laryngopharynx
- Esophagus
- Trachea
8
Q
Pharynx: Functions
A
- Part of conducting portion of the system providing a passageway for air
- Provides a resonating chamber for speech sounds
9
Q
Larynx: Components
A
- Hyoid bone
- Epiglottis
- Ventricular fold (false vocal cord)
- Vocal fold (true vocal cord)
- Trachea
10
Q
Larynx: Functions
A
- 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
11
Q
Trachea and Bronchi: Components
A
- Larynx
- Trachea
- Primary bronchi
- Secondary bronchi
- Tertiary bronchi
- Bronchioles
- Terminal bronchioles
- Diaphragm
12
Q
Trachea and bronchi: Function
A
- 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
13
Q
Lungs: Functions
A
- 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
14
Q
Lungs: Components
A
- Pulmonary venule
- Pulmonary arteriole
- Pulmonary (alveolar) capillary
- Alveolus
- Alveolar ducts
- Alveolar sac
- Bronchiole
- Right lung
- Middle lobe
- Superior lobe
- Inferior lobe
- Left lung
15
Q
Male reproductive system: Functions
A
- Produces, stores and transports sperm for fertilization of female oocyte
- Produces the hormone testosterone in the testes
16
Q
Male reproductive system: Components
A
- Epididymis
- Testes
- Ductus (vas) deferens
- Penis
17
Q
Female reproductive system: Functions
A
- 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
18
Q
The female reproductive system: Components
A
- Uterus
- Uterine (fallopian) tube
- Ovary
- Cervix
- Vagina
- Mammary gland
- Nipple
19
Q
Uterus: Components
A
- Uterine (fallopian) tubes
- Uterus
- Vagina
- Endometrium
- Myometrium
- Perimetrium
20
Q
Uterus: Functions
A
- Site of implantation of fertilized ovum (mature egg)
- Site of development during pregnancy and labor
- Site of menstration
- Passageway for sperm to fertilize oocytes
21
Q
Fallopian tubes: Components
A
- Uterine (fallopian) tubes
- Fimbriae of uterine tube
22
Q
Fallopian tubes: Functions
A
- Transports oocytes from ovaries to the uterus
- Usual site of fertilization of female oocyte by male sperm
- Transports fertilized ovum to uterus for implantation
23
Q
Ovaries: Components
A
- Ovaries
- Uterine (Fallopian) tubes
- Uterus
24
Q
Ovaries: Functions
A
- Oocytes are formed and developed and transported to uterine tubes
- Produces and secretes hormones - estrogen, progesterone, inhibin, and relaxin
25
Mammary gland: Components
- Nipple
- Mammary duct
- Lactiferous duct
- Lobule containing alveoli
26
Mammary gland: Functions
- Synthesizes, secretes and ejects milk for a newborn
27
Epididymis: Composition
- Spermatic cord
- Ductus (vas) deferens
- Epididymis
28
Epididymis: Functions
1. Epididymis is site of sperm maturation
2. Ductus deferens transports and stores sperm
29
Testes: Components
- Testicular blood vessels, Lymphatic vessels, and nerves
- Testis
30
Testes: Functions
1. Produces sperm
2. Produces testosterone
31
Epididymis and Ductus (vas) deferens: Components
- Spermatic cord
- Ductus (van) deferens
- Epididymis
32
Epididymis and Ductus (vas) deferens: Functions
1. Epididymis is site of sperm maturation
2. Ductus deferens transports and stores sperm
33
Penis: Composition
