Muscles
Muscle fibers are excitable and carry *BLANK BLANK* along their membrane.
What are action potentials
The partial pressure of a gas in a fluid represents the quantity of gas *BLANK* in the fluid when the gas molecules enter and leave the liquid at the same rate, or when the gas in the state and the liquid state are in equilibrium.
What is dissolved.
The human lung is filled by *BLANK* pressure.
A function of blood includes the transport of *BLANK* and maintenance of body temperature.
What is heat.
*BLANK* are the smallest arteries.
What are arterioles.
When Ca2+ levels increase in the cytosol, Ca2+ binds to *BLANK*
What is troponin (TN).
Respiration using oxygen is known as *BLANK BLANK*, while respiration without oxygen is known as *BLANK BLANK*.
What is aerobic respiration; anaerobic respiration.
The entire lung is filled with tiny circular structure called *BLANK*.
What are alveoli.
Myoglobin consists of only *BLANK* subunit and is found in muscles. It acts as a local store of *BLANK*.
What is one (1); oxygen
Blood is moved throughout the body by *BLANK BLANK*.
A motor unit refers to a group of muscle fibers controlled by *BLANK (number)* motor neurons.
What is one (1).
Atmospheric air mainly consists of *BLANK* and *BLANK* plus small amounts of CO2 and minuscule amounts of other gases.
What are nitrogen and oxygen.
In *BLANK BLANK* a pressure difference causes all molecules to move in the same direction. IN *BLANK* molecules are moving randomly in all directions.
What is bulk flow; diffusion.
Each subunit of hemoglobin contains a *BLANK BLANK* surrounded by Nitrogens and a "globin" protein
Heart muscle cell action potentials are initiated by *BLANK* cells that spontaneously generate action potentials.
What are autorhythmic cells (pacemaker cells).
The time course of a single twitch reflects the time it take Ca2+ to reach the *BLANK* and then to diffuse away.
What are myofibrils.
The difference in *BLANK BLANK* is the driving force that moves gas from one location to another.
The thoracic cavity is covered by a membrane called the *BLANK BLANK* while the lungs are surrounded by *BLANK BLANK*.
What is the thoracic pleura; lung pleura
When CO2 rapidly diffuses out of the blood, *BLANK* is converted to CO2, and CO2 unbinds from Hb. This adds to the CO2 that diffuses out into the alveoli and is removed by the lungs.
What is HCO3-
Action potentials start in the pacemaker on the *BLANK BLANK*.
What is the right atrium.
The contraction of skeletal muscle is much more sustained than in smooth muscle because smooth muscle contraction is controlled by *BLANK BLANK BLANK*.
What is the autonomic nervous system
Diffuse of gas across a sheet of tissue follow the equation Q = KA(P1-P2)(1/d), where Q = *BLANK*, K = *BLANK* and d = *BLNAK*.
What is the rate of diffusion; constant depending on temperature; the thickness of the material.
The*BLANK BLANK* represents the maximum volume of air that can be exchanged with a maximum inhalation and exhalation whereas *BLANK BLANK* is the small amount of air still remaining in the lungs after maximum exhalation.
What is vital capacity; residual volume.
During exercise, increased ventilation seems to be driven by the *BLANK*, which senses the increase in motor impulses to the stimulating muscles.
What is the brain
The aortic valve closes because of the higher *BLANK BLANK* in the aorta.
What is the diastolic pressure.
