Alborosie3 years ago
4 0

The lungs are <em>separated by the mediastinum</em>. This anatomical region is the central compartment o f the thoracic cavity. It is located between the lungs and contains all the principal tissues and organs of the chest such as the heart, trachea, esophagus, thymus etc. The lungs are the only chest organs not contained in this region.

It is surrounded by the breastbone, vertebral column and is bounded laterally by the pericardium as well as being continuous with the loose connectinve tissue of the neck.

Which of the following is the correct sequence of structures that sound waves pass through on the way to the auditory nerve?
8_murik_8 [283]

The option that correctly indicates the sequence of structures that sound waves pass through on the way to the auditory nerve is: "Pinna → Malleus → Incus → Stapes → Auditory canal → Tympanic membrane → Cochlea → Auditory nerve" (Option B)

<h3>What is the function of the Auditory Nerve?</h3>

The auditory nervous system connects the cochlea to a station in the brainstem (known as the nucleus). Neural impulses pass from that station to the brain, notably the temporal lobe, where sound has meaning and we hear.

Auditory function refers to how a person hears and processes information in difficult-to-understand situations on a daily basis. Children with hearing loss or who have difficulty tolerating noises might benefit from an auditory function exam.

(GIVING BRAINLIEST!!!!!!!) JUST FILL IN THE BLANK SPOTS!!
GaryK [48]

Answer:

Here you go!

Explanation:

Grasslands are areas where the vegetation is dominated by grasses. However, sedge and rush can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth.

Temp -20°C to 30° C (-4°F- 86)

Precip 500-900 mm a year

Humidity 50-60%

Mountain precip- more than 20 in

Mountains aren't very humid because they're elevated.

true or false? to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thor
faltersainse [42]

The thorax is a very vital and important organ in the human body.

  • It is a structure that serves as a<u> </u><u>protective covering</u> for organs in the body such as<u> the lungs, the heart, some vital blood vessels</u> e.t.c

It is<u> false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>

  • When a person breathes in,  <u>the chest cavity expands (the volume increases) and the pressure in the thorax decreases.</u>

  • When a person breathes out, <u>the chest cavity decreases in size, and the pressure in the thorax increases. </u>

  • Therefore, we can see that the <u>process of breathing in humans</u>, follows the <u>principle of Boyle's Law.</u>

  • Boyle's law states that as the<u> volume increases there is a decrease in pressure</u> and <u>as the volume decrease there is an increase in pressure. </u>

Therefore, It is <u>false</u> that to <em>make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.</em>

What is potential energy​
Lelu [443]

Answer:

The energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system.

Explanation:

Energy is a delicate notion that is extremely difficult to master. Energy is sometimes described as the ability to accomplish labor, that is, to push anything against a force. That isn't completely correct, since due to the Second Law of Thermodynamics and the fact that much energy is merely mass, there is a lot of energy that isn't accessible to do any work. We're on somewhat better ground with potential energy. When we say there is potential energy, we mean that there is something in a system that, if permitted to alter, has the capacity to accomplish work. Saying that there is potential energy is a form of abbreviation. Consider gravitational potential energy. If two masses are separated by a distance, we might let them fall together and accomplish some work, perhaps by pulling a rope tied to a wheel or whatever. We have the energy to get there. Of course, it is a fraction of the overall energy in the system. When we get to notions like that, we must count a lot more. Nonetheless, some cosmological models require a type of negative gravitational potential energy to make total energy conservation work. According to such views, nearly all of the universe's mass condensed out of the vacuum to offset the negative energy associated with the inflationary epoch. As a result, the universe's total energy is zero. It is not the sole hypothesis, but it is useful in that it answers the issue of why there is something rather than nothing. It would imply that there is nothing completely, but it is unevenly dispersed. One of the two major forms of energy is potential energy. Potential energy is the amount of energy that an object can hold. It is the power that a thing has while it is not in motion. The potential energy of a moving item increases as it slows down. The object's capacity strength reduces as it accelerates. Potential energy is the electricity that occurs as a result of the relative locations (configurations) of the components in a physical machine. This energy form has the capacity to modify the state of other things around it, such as the configuration or movement. Potential energy encompasses a wide range of energy kinds.
