Under what internal condition does air tend to flow out of the lungs?
Air tends to flow out of the lungs when the internal pressure of the lungs is higher than the atmospheric pressure. This pressure difference is created by the contraction of the diaphragm and intercostal muscles during exhalation, which reduces the volume of the lungs and forces air out.
Under what internal condition does air flow out of the lungs?
Air flows out of the lungs when the internal pressure is higher than the atmospheric pressure, causing expiration to occur. This pressure gradient is established by the contraction of the diaphragm and intercostal muscles during exhalation.
What is diaphragm caustic soda?
Diaphragm caustic soda is a type of caustic soda produced using an electrolysis process that involves the use of a diaphragm to separate the anode and cathode compartments. The diaphragm prevents the mixing of chlorine gas (produced at the anode) with the sodium hydroxide solution (produced at the cathode), ensuring higher purity of the final product. This method is commonly used in chemical industries for the production of caustic soda.
What voltage produced maximal contraction of the muscle?
The voltage that produces maximal contraction of a muscle is called the maximal stimulus voltage. This voltage is typically higher than the threshold voltage required to elicit a muscle contraction and ensures that all muscle fibers within a motor unit are stimulated to contract simultaneously, leading to a stronger contraction.
How does inhalation occur in the human body?
Inhalation is the process of taking air into the lungs. For this to occur, the air pressure inside the lungs must be lower than that of the external atmosphere as air flows from areas of higher pressure to lower pressure. This is achieved by the contraction of the external intercostal muscles and the relaxation of the internal intercostals which acts to pull the ribcage upwards and outwards, hence, increasing the volume of the thoracic cavity. The diaphragm also contracts to extend the cavity further downwards. Due to the function of the pleural membrane, the size of the lungs is increased which, in turn, creates an area of lower air pressure inside the lungs; hence, air is drawn into the lungs.Read more: What_happens_during_inhalation_and_exhalation

How does the action of the external intercostal and diaphragm muscles draw air up your nose?
External intercostal and diaphragm increase the volume of the lungs, this action dicreases the pressure of the lungs. (we know pressure moves from the region of higher region to lower, in this case pressure is high in atmosphere and low in lungs). So air gets drew up in our nose.
What is the difference between men and women respiration?
Men tend to have larger lung volumes and higher respiratory rates compared to women. Additionally, women have higher tendency to have stronger diaphragm muscles, which can affect the breathing patterns. However, on average, there is no significant difference in the efficiency of respiration between men and women.
What causes air to flow out of the lung during expiration?
Relaxation of the diaphragm and intracostal muscles causes the pressure inside the thorax to be higher than that outside the body. the contraction and relaxation of these things change the volume of lungs and thus the air pressure in the lungs. Air moves from high pressure to low pressure, so during inspiration, the external intercostal muscles contract (the internal intercostals relax) which brings the rib cage upwards and outwards, the diagphram contracts and goes downwards which all increases the size of the thoracic cavity (and due to the plueral membrane) and thus that of the lungs. This creates an area of lower pressure in the lungs and therefore air is cause to flow in. The opposite occurs in expiration. the intercostal muscles work to pull the ribcage inwards and diaphragm bulges upwards making the lungs smaller. this then creates an area of high pressure in the lungs and air is drawn out " what way does it goes? high to low. "
What kind of nerves control skeletal muscle contraction?
The muscle spindle helps to control the contraction of muscles. It is a special sensory organ that uses sensory neuronal fibers to find how long the intrafusal muscle fibers are.
Does the diaphragm contract during inhalation?
Yes.Contraction of the diaphragm causes it to flatten, lowering its dome. This increases volume in the thoracic cavity and creates a vacuum. This vacuum inflates the lungs by drawing air into the body.Boyle's Law - If the size of a closed container is increased, the pressure of the gas inside the closed container decreases.In this scenario, the thoracic cavity is the "closed container" that became bigger in size with the diaphragm contracting and flattening. With the increase in size, the pressure decreases.For air to flow into the lungs, the pressure in the lungs must become lower than the atmospheric pressure. The diaphragm is the mechanism that achieves this process.During exhalation, the diaphragm relaxes and raises, returning to its dome-shape. This causes the volume to decrease and the pressure to increase to a level greater than atmospheric pressure, making it impossible to receive any air.No, the diaphragm is contracted during inspiration, becoming flattened.It is relaxed during expiration, becoming dome-shaped.
Why is the ventricular wave higher?
Assuming you are talking about Electrocardiogram readings, the ventricular contraction is represented by the 'R' wave. The R wave is so much higher because the left and right ventricles are made up of the largest and strongest muscles of the heart and show the largest electrical energies on the ECG when they are contracted.
Why do athletes have a higher cardiac output?
regular aerobic exercise strengthens heart muscles which increases stroke volume (the volume of blood ejected with each contraction). since cardiac output = stroke volume * heart rate, this ultimately increases cardiac output.
Do men have a higher amount of muscles than women?
Naturaly, yes. But if women exirsize they can achieve a higher amount of muscles. -Lagasu ---- Check out the link for more information:
A muscle is stimulated and exhibits a contraction twitch Before this twitch is over it is stimulated again and a second twitch occurs piggyback on the first one and causes a higher contraction?
summation
Do slow twitch muscles have a higher concentration of mitochondria compared to fast twitch muscles?
Yes, slow twitch muscles generally have a higher concentration of mitochondria compared to fast twitch muscles. Mitochondria are responsible for producing energy in cells, and slow twitch muscles require more energy for sustained, endurance activities.
