Does the relaxation of the diaphragm causes a slight vacuum the lungs?

No! When you inhale it does. So contraction not relaxation.

What causes a vacuum leak?
Vacuum hoses dry and brittle bad diaphragm in vacuum operated motors
What is the working principle of vacuum gauge?
There are several types. Perhaps the commonest type involves a flexible diaphragm that is impervious to gases. One side of the diaphragm is in a closed chambre and exposed to air at standard pressure. The other side of the diaphragm is in a chambre that can be connected with hose or tubing to the vacuum whose pressure is to be measured. The degree of deflection of the diaphragm indicates the pressure differential to which it is exposed when it is connected to a vacuum. Please see the link for more information.
How does a diaphragam help in inhalation?
The diaphragm flattens to help inhalation. This creates more space in the chest cavity, so the pressure drops which causes a vacuum. This makes air rush in and inflate the lungs.

check the vacuum diaphragm for leaks. Might be a hole in the vacuum line.
Your heater does not get hot in your 1989 Lincoln town car you changed the themostant and ambient control sensor it will not get hot?
Check the heater/AC controls; they feed vacuum to a diaphragm that controls the heat door within the duct up under/behind the glove box. You will probably find vacuum present all of the time at the diaphragm which keeps the heat turned off. To confirm, disconnect and plug the vacuum line at that diaphragm and see if there is now heat (the engine will have to be warmed up & running for this test). If there is heat with the vacuum line removed from the diaphragm, the heater controls are bad and would have to be replaced (a time consuming & probably expensive job). Or, you may just want to rig that vacuum line to some aquarium air tubing and a small air valve that would allow you to vent the vacuum off of the diaphragm.
Why does your truck idle goes up and down when you press down on the brakes?
Your brake master cylinder uses a vacuum assisted module to increase the hydraulic force on the brakes while reducing the amount of effort the driver has to put on the pedal. When you press down on the brakes, it employs this vacuum-powered diaphragm which "borrows" vacuum from the intake manifold. This initially causes a drop in manifold vacuum and thus you see this with a slight drop in idle speed. It's more pronounced on bigger engines, and prior to computer controls and fuel injection it was actually QUITE pronounced. Smaller engines with fuel injection and computer control do not see this byproduct as much.
Where is the brake booster on a 98 civic?
Mounted between the Master Cylinder & the Firewall on the driver's side. It is the large vacuum diaphragm with the vacuum hose going to it.
What does a automobile vacuum diaphragm do?
It opens /closes heater duct doors and sometimes 4 barrel carburetor secondaries. It is basically a vacuum actuated servo
What moves air from the nose to the bronchi?
The vacuum created by down-ward movement of the diaphram.
How does diaphragm help during the inhaling and exhaling process?
When the diaphragm contracts, it pulls down and creates a vacuum in the lungs, which helps in breathing in.
What is the Large muscle that helps mammals breathe?
The diaphragm is the primary muscle involved with breathing. When you want to take a breath in (inhale) you contract your diaphragm. This makes the thoracic cavity larger, decreasing the pressure in the thoracic cavity and generating a vacuum. Air is drawn into the lungs because of the creation of this intra-thoracic vacuum. When you relax your diaphragm the elasticity of your lungs will force air back out (exhalation).
