When a person exhales what happens to the diaphragm?
The diaphragm muscles contract and relax pulling the diaphragm down and then releasing it. When we inhale, our diaphragm muscles contracts and flattens. When we exhale, they relax and arch upwards.
Do phloem travel up or down?
the xylem transports water upwards and and the phloem transports food downwards in a plant .
When you inhale what direction does the diaphragm move?
Upwards, toward the head.
What are the important laws of physics?
One I know is that all is thrown upwards come back downwards.
What happens when you breathe out air?
When you breathe in, your diaphragm contracts and is pushed upwards. Your lungs expand and fill with air. The pressure within your chest cavity increases, and the body goes through the gas exchange process, providing red blood cells with oxygen. The carbon dioxide within red blood cells is then transferred into the lungs, and is exhaled along with traces of oxygen and other substances within the air. The diaphragm relaxes, lungs deflate, and pressure within the chest decreases.

Movement of the diaphragm during inhalation?
During inhalation, the diaphragm contracts flattening out its usual dome shaped appearance. This has the effect of lengthening the lungs and increasing the intrapulmonary volume. When the volume increases, the pressure drops and air flows into the lungs.
When you breath out which direction does your diaphragm go?
When you breathe out the diaphragm moves upwards to push the air out of the lungs. When you breathe in the diaphragm moves downwards to draw air into the lungs. When you breathe out your diaphragm contract and moves upwards towards your head. when you breathe in too much your diaphragm explodes
How does the diaphragm muscle assist with respiration?
Respiration. The diaphragm is a sheet of muscle separating the chest cavity from the abdominal cavity which, when relaxed, domes upwards; on breathing in the diaphragm contracts & flattens down, thus increasing the capacity of the chest, and causing air to be drawn into the lungs.When the diaphragm contracts that causes the volume of the lungs to increase. When the lung volume increases, the air pressure drops causing air to come in from outside (inhaling). When the diaphragm relaxes, the process is reversed. Lung volume decreases, air pressure builds, and air is forced out (exhaling).
Does a black hole move upwards or downwards?
Downwards
How do the lungs take in and breathe out?
During inspiration the ribs move upwards and outwards and the diaphragm contracts ,thus,increasing the volume of the thoracic cavity.this leads to a decrease in pressure inside the lung.therefore the air from outside rushes in . During expiration the ribs move inwards and downwards and the diaphragm relaxes thus,creating low pressure .this leads to the expulsion of air from our body.
What do you think the diaprhagm does?
First, it's diaphragm. Second, as we breathe in, the chest expands, the diaphragm flattens and the intercostal muscles lift the ribs upwards and outwards to allow the lungs to fill with air. As we breathe out, the intercostal muscles relax and the diaphragm becomes dome shaped. See related link for more details
What is the antonym for downwards?
upwards
Can crabs swim upwards?
yes, crabs can swim left, right, upwards and downwards
How mercury rises in thermometer by rising temp?
The mercury in the thermometer's tube expands and contracts due to the surrounding temperature. As the mercury is inside a narrow tube, it can only expand upwards, and contract downwards.
