When air moves into the lungs when the diaphragm muscles do what?
The diaphragm moves down to make the lungs expand (inhalation)
Do lungs have musles?
yes because organs are made up of tissues and so are muscles and for the lungs to move they need the muscle. So yes your lungs do have muscles.
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.
Which respiratory tubes are primarily composed of smooth muscle and affect the flow of air to the alveoli?
There are no smooth muscle lined tubes in the respiratory system. The air is pulled into the lungs when the rib cage expands. The lungs are attached to the inside of the rib cage and move as it moves. Now there are skeletal muscles between the ribs called intercostal muscles. These muscles affect the rise and fall of the ribs during respiration.
Moving muscles in order to make air flow into and out of the lungs?
The term for moving muscles in order to make air flow into and out of the lungs is breathing. The main muscle that moves is the diaphragm, which sits just below the lungs and causes air to flow in and out as it contracts and expands.
What structure is primarily responsible for keeping us breathing?
the lungs fill with air because the diaphragm (a muscle that runs underneat the ribcage) moves and causes the lungs to inflate
When Air moves out of the lungs the pressure inside the lungs is?
when air moves out of the lungs, the air pressure decreases
What is able to move up and down from moving air in and out of lungs?
the diaphragm is a muscle located below the lungs. When the muscle tissue of the diaphragm contracts, it moves down, creating a vacuum inside the lungs, and pulling air into them. To breathe out, the diaphragm simply relaxes, springs back up, and the air is expelled. Not all of the air ever comes out of the lungs during an exhale.
What is the movement when your muscles move your ribs to make the lungs bigger and smaller?
It is air that does it, as well as the rib muscles themselves. The diaphragm contracts, expanding the internal area of the thoracic (chest) cavity, causing a drop in pressure. Air is then drawn through the nose into the lungs, which expand, causing the ribs to move to accomodate this.
Air moves from the outside into the lungs through?
The air moves from the outside into the lungs through the windpipe.
Where does the force that moves oxygen into the lungs originate from?
The diaphragm is a sheath of muscle that separates the organs of the chest and abdomen. When you take a breath, you're flexing the diaphragm and a number of smaller muscles in your chest. This inflates the lungs, creating a partial vacuum, drawing air into your nose and mouth and into your lungs.
What makes air moves into and out the lungs?
Pulmonary ventilation or breathing has two phases. Inspiration or inhalation moves air into the lungs and expiration or exhalation moves air out of the lungs. The lungs are enclosed within the thoracic cavity. Thus changes in the shape and size of the thoracic cavity result in changes in the air pressure within that cavity and in the lungs. This difference in air pressure causes the movement of air into the lungs. Air moves from an area where pressure is high to an area where pressure is low. Respiratory muscles are responsible for the changes in the shape of the thoracic cavity that cause the air movements involved in breathing.The abdominal diaphragm is (or should be) the major muscle driving respiration.Source(s):Structure and function of the body
