What else can I help you with?
What allows you to inhale and exhale?
Inhalation requires the contraction of the diaphragm, and exhalation occurs when it relaxes.
Exhalation occurs when what relaxes?
The lungs don't actually contract. all the work is done by muscles in the chest.When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
When nerve impulses pass to the diaphragm the diaphragm relaxes and exhalation occurs is this true or false?
False. When nerve impulses pass to the diaphragm, it contracts, which expands the chest cavity and allows air to enter the lungs (inhalation). The diaphragm relaxes during exhalation, allowing air to be pushed out of the lungs.
What movement occurs when the triceps contract?
The biceps muscle relaxes!!!!!=)
What exhalation occurs when the relaxes causing the lungs to contract?
The lungs do not contract. When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the spacein the chest cavity.As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.Breathing out requires no effort from your body unless you have a lung disease or are doing physical activity. When you're physically active, your abdominal muscles contract and push your diaphragm against your lungs even more than usual. This rapidly pushes air out of your lungs.
What happens when the diaphragm and the rib cage muscles relax?
The diaphragm relaxes during EXHALATION. Your diaphragm flattens when you inhale, creating more space for the lungs to take in more air.
What happens to a muscle when it relaxes?
all the muscle filaments move away from each other
Does exhalation occur when the diaphragm and rib cage muscles relax?
Yes, exhalation occurs when the diaphragm and muscles of the rib cage relax.
What does the diaphragm muscle do when air moves into the lungs?
The diaphragm moves down to make the lungs expand (inhalation)
The greatest water loss per day occurs?
through lungs (exhalation)
Which condition occurs when the muscle between the esophagus and the stomach is weak or relaxes inapropriately?
gastroesophageal reflux disease
When the diaphragm contracts does lung volume increase or decrease?
The downward contraction of the diaphragm (below the lungs) decreases the pressure within the lungs by expanding the thoracic cavity. The lungs sag into the cavity, and outside air flows into the lungs.The contraction of the diaphragm allows the person (or animal) to inhale air. When the diaphragm relaxes, it pushes upward on the lungs and exhalation occurs.
