Thoracic volume has somthing to do with heart and lungs. I don't know the exact definition but i hope this will helpThe overall Thoracic volume of Apatosaurus has been estimated at 1,700 liters allowing for a 500-liter, four-chambered heart (like birds, not three-chambered like reptiles) and a 900-liter lung capacity. An Apatosaurus is the biggest of a long neck dinosaur.

What happens to the pressure and volume inside the thoracic cavity when you pull the rubber diaphragm down the lung model?
When the diaphragm is pulled down, the volume of the thoracic cavity increases, and the air pressure in the thoracic cavity decreases. This causes inhalation.
What happens to the thoracic cavity when the diaphragm relaxes?
When the diaphragm relaxes, the volume of the thoracic cavity decreases. The resultant decrease in thoracic cavity leads to an increase in the pressure. This increase in pressure leads to the exhalation of air out of the lungs into the atmosphere.
How do you find thoracic gas volume?
they die of heat stroke
Thoracic volume is increased during normal breathing by the?
diaphragm
When the volume of the thoracic cage decreases what pressure increases?
your dick will shrink
Do intercostal muscles change the volume of the thoracic cavity?
Yes. Along with the diaphram.
What is the dome-shaped muscle under the thoracic cavity and what are its functions?
The dome-shaped muscle under the thoracic cavity is the diaphragm. Its function is to contract to increase the volume of the thoracic cavity, thereby decreasing pressure in the lungs and causing inspiration.
When air moves into the lungs when the diaphragm muscle?
Descends. When you inspire, the diaphragm descends, the thoracic volume inreases, the intra-thoracic pressure drops. The difference in the environmental pressure and the intra-thoracic pressure causes air to flow into the lungs.
How is the thoracic pressure decreased during inspiration?
Inspiration causes a drop in thoracic pressure, so the blood pressure in the area may drop, so the feeling of the pulse may feel weaker (though this would have to be an extreme case). It also can cause splitting of the second heart sound as the lungs take in more blood.
What does thoracic mean?
It pertains to the thorax... But you can use it as a thoracic spine, thoracic surgery, thoracic cavity, thoracic outlet syndrome, thoracic spine pain, thoracic vertebrae, thoracic medicine, thoracic surgeons, thoracic strains, sprain thoracic, or thoracic spine disorder; it's pretty self explanatory.
Which body cavity is bounded by the ribs?
The Thoracic Cavity
The order or events that occur during expiration when the lungs are filled with air.?
four movements 1 inspirator muscles relax 2 thoracic volume decreases 3 thoracic pressure increases 4 air flows out of lungs
