During exhaling, air out of lungs, diaphragm is pushed upward and hence partial pressure in the ribs increases and the pressure outside the body is little less so air goes out of the body. During inhalation exact opposite of exhalation occurs
Total pressure = partial pressure outside our body + partial pressure inside our body
What else can I help you with?
How does air pressure vary with temperature changes?
Air pressure decreases as temperature increases, and air pressure increases as temperature decreases. This is because warmer air is less dense and exerts less pressure, while cooler air is denser and exerts more pressure.
What is a easy sentence for exerts?
A human exerts energy, while doing work
Which is true about intrapulmonary pressure and intrapleural pressure?
Intrapulmonary pressure is the pressure inside the lung alveoli, while intrapleural pressure is the pressure in the pleural cavity. During normal breathing, intrapleural pressure is lower than intrapulmonary pressure, creating a pressure gradient that helps keep the lungs inflated.
Who exerts more pressure on the ground a 500N woman standing in 0.005m high heels or a 500N woman standing in 0.05m work boots?
The woman in high heels exerts more pressure on the ground because the pressure exerted is force divided by area; the smaller contact area of the heels concentrates the force, resulting in higher pressure. So, a 500N woman standing in 0.005m high heels exerts more pressure than a 500N woman standing in 0.05m work boots.
Three examples of force pairs that happen when homework is being done?
The hand exerts a force on the pen to write on paper, while the pen exerts an equal but opposite force back on the hand. The book exerts a force on the table due to gravity, while the table exerts an equal but opposite force upwards on the book. The foot exerts a force on the ground to stay balanced while sitting on a chair, and the ground exerts an equal but opposite force upwards on the foot.
Is gauge pressure the same as absolute pressure?
No, gauge pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the total pressure including atmospheric pressure.
What is the difference between static and total pressure in fluid dynamics?
In fluid dynamics, static pressure is the pressure exerted by a fluid when it is not in motion, while total pressure includes both the static pressure and the pressure caused by the fluid's motion.
What is the difference between gage pressure and absolute pressure?
Gage pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the total pressure including atmospheric pressure.
What is the difference between persuit diving and deep plunging?
Pursuit diving exerts greater pressure on the seabirds while deep plunging refers to going deep in the sea in search of the seabirds.
What is blood pressure used to evaluate?
Your systole and diastole (or systolic and diastolic pressure). Systolic pressure is the pressure your blood exerts on blood vessels when your heart pumps out blood while diastolic pressure is the pressure your blood exerts on blood vessels when your heart is at rest(in between pumps). Blood pressure is stated as systolic pressure/diastolic pressure. The normal BP is 120/80 mmHg.
What is the difference between gauge pressure and atmospheric pressure?
Gauge pressure is the pressure measured relative to atmospheric pressure, while atmospheric pressure is the pressure exerted by the Earth's atmosphere on a surface. Gauge pressure accounts for atmospheric pressure, while atmospheric pressure is the total pressure exerted by the atmosphere.
If a drug dilates blood vessels does it raise or lower blood pressure?
When nicotine exerts its effect on the heart, the pulse rate of the smoker will increase while smoking the cigarette. A consequence of the pulse rate increasing is that the nicotine will raise the smoker's blood pressure.
