Week 9 Vocabulary

Nose, Pharynx, larynx, bronchi, lungs

Opening into the nose (coarse hair lines vestibule to filter large dust particles)

located in the superior meatus

Warm and moisturize air, smell, and speech tone

passageway for food and air, resonating chamber for speech

internal nares and eustachian tubes

connection to the mouth

connects esophagus with the larynx

Prevents food and liquid from entering the trechia

largest supporting cartilidge, Adams apple

Connects with first trachial ring

Opening above true vocal chords. Speech caused by air vibrating vocal chords

Tubular passage for air - Anterior to esophagus - extends fro cricoid to first thoracic vertebrae

A procedure to allow breathing if the throat is blocked

trachea branches into L & R - Into secondary bronchi - into tertiary bronchi - into bronchioles into terminal bronchioles

Encloses and protects lungs

Outer

Inner

between pleaura prevents friction

surrounds the alveolar ducts - grape like, surrounded by capillary network

Breathing

Diaphragm and intercoastals contract - Pressure decreases in lungs, air rushes in

Diaphragm and inercoastals relax - Pressure in lungs increases, air rushes out.

Maintains homeostasis by removing and restoring solutes and fluids. Kidney is primary filtering

nitrogenus waste, drugs and toxins

maintained by urinary system

regulation

maintained by producing renin

Produces erythrepoietin, which stimulates red blood cell production

Producing calicferol, a Vitamin D precursor

Kidneys, about the size of a closed fist

Passage area for ureters, vessels, and nerves

Surrounding Layer

Inner area - Renal pyramids: tips point inward

Outer area - cortical material between pyramids - Cortex and renal pyramids contain nephron

Functional units in kidneys

Funnel shaped, collects urine from pyramid ducts

Formed from minor calyx - join to form renal pelvis - Narrows to for ureters

Double walled globe

filter

Proximal convoluted tube - descending limb, loops and ascending limb of Henle - Distal convoluted tubule

moves urine to the outlet

transports 1200mL of blood per minute, interlodal arteries

Drains the cleaned blood out of kidneys

controls blood concentration and volume - Regulates pH - Removes toxins from blood - Stimulates RBC production

glumerular filtration - tubular reabsorbtion - tubular secretion

95% water, urea, uric acid, electrolytes. 56mL and Hour is normal. 30mL an hour might signify kidney failure

Extensions of renal pelvis

Peristolsis, gravity, hydrostatic pressure

Held in position by peritoneum, Detinsor muscle, three-layered smooth muscle.

involuntary control

Expulsion of urine from bladder

Voluntary control

700-800 mL -200-400mL: conscious of need to urinate - stretch receptors

Connects bladder to the outside

tip of penis

Process in where genetic material is passed

Produces sex cells, sperm to egg to form zygote - Zygote develops embryo

Prduces sperm and male hormones

Accessory Organ - Elevates and descends depending on temperature

Transporting and supporting structure

Transport sperm cells

Network of ducts

Site of sperm cell maturation

Located on posterior border of the testes

ejects spermotazoa into urethra

Terminal duct (urethra orifice of meatus)

Produces viscous part of semen

Produces fluid/liquid part

Produces mucous

Mixture of sperm cells and other secretion - Fructose -Neutralizes acidity in vagina - Acts as transport medium -2.5-6mL (Average volume)

End of the shaft

Loose skin covering glans penis -circumcision: removal of prepuce

Primary sex organ - held in place with ligaments - covered by garminal epithelieum

Begins in developing female fetus (700,000 produced) -Developing eggs

Uterine tube

site of menstration, egg implantation and labor -pear shaped -Uterine cavity -cervicle canal (interior of cervix)

(2-8 days)

4-7 days

~10 days

or secretory phase (~14 days) -corpus luteum develops

Development of female secondary sex characteristics

Passageway for menstrual flow

External genetalia

Majora/Minora

erectile tissue

Vaginal and Urethral orifaces
