Perfectly

This law states that at constant temp., gas volume is inverse to pressure

Boyle’s Law

Perfectly

This law states that at constant pressure, gas volume is proportional to absolute temp.

Charles’ Law

Perfectly

This is the minimum interval of time necessary to electrically stimulate a muscle or nerve fiber using twice the minimum current to elicit threshold response

Chronaxie

Perfectly

This law(?) will give the membrane potential on the inside of a membrane when 2 univalent positive ions, Na+ & K+ & 1 univalent negative ion, Cl- are involved

Study These Flashcards

Goldman

This law states that gas solubility in a liquid is proportional to gas pressure

Henri

This law limits respiratory excursion via the Vagus nerve

Hering Breuer

This law states that the tension in an artery will be proportional to the radius of the vessel

LaPlace's Law for arteries

This law states that ventricular pressure depends on muscular tension, size, & shape of the heart

LaPlace's Law for the heart

This law states the potential level across a membrane exactly opposes net diffusion of particles through the membrane

Nernst Law(? don't know if it's a "law")

What is the minimum electrical current of infinite duration to elicit a threshold response called?

Rheobase

This law states that cardiac output is equal to venous return

Starling's law

This is when hemoglobin becomes more acidic binding w/ oxygen. Causes CO2 & H+ protons to be expelled into the aveoli. Part of the Bohr Effect

Haldane Effect

This lung volume is considered normal breathing (500ml). Fires Herring-Breuer reflex

Tidal Volume

This lung volume is forced inspiration (3000ml). Shuts off Herring-Breuer reflex

Inspiratory Reserve Volume

This lung volume is forced expiration (1100ml)

Expiratory Reserve Volume

This lung volume keeps the lungs from collapsing (1200ml)

Residual volume

This is a combination of IRV + TV (3500ml)

Inspiratory Capacity

This is a combination of ERV + RV (2300ml)

Functional Residual Capacity

This is a combination of IRV + TV + ERV or IC + ERV (4600ml)

Vital capacity

This is a combination of IRV + TV + ERV + RV (5800ml)

Total lung volume

What is air in the pulmonary tree not involved w/ gas exchange called?

dead space

Respiration is controlled by what nucleus?

Dorsal motor nucleus of Vagus

Muscle lengthens while it contracts

Eccentric

Muscle shortens while it contracts

Concentric

Muscle contracts w/o joint movement on muscle lengthening

Isometric

Muscle contracts w/ joint movement & constant weight

Isotonic

Muscle contracts w/ joint movement & constant weight/speed

Isokinetic

AKA goblet cells in the lungs. Produce mucus, serves as a defense mechanism in case of noxious air

J cells

What is the apex of lung/cervical pleura called?

Cupola

This creates the potential space for breathing. It's inf. to the root of the lung.

Pulmonary lig.

Fluid in the lungs collects where?

Costodiaphragmatic recess

What is the best test for Glomerular Filtration Rate (GFR)?

Inulin

How many renal pyramids are in one kidney?

8-12

How is the neurohypophysis connected to the hypothalamus?

Infundibulum (neural stalk)

What makes inhibin in females? Males?

Corpus leuteum; Sertoli cells

What is "growth hormone" for cartilage called?

Somatomedin (made in liver)

Which is more powerful, faster acting, & less abundant, T3 or T4?

Where is calcitonin made?

Parafollicular cells of thyroid
