Answer: it doesn't
Explanation: Why? The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve. Three leaflets on the aortic valve open and close with each heartbeat to allow one-way flow of blood. The aorta is a tube about a foot long and just over an inch in diameter. The aorta is divided into four sections:
• The ascending aorta rises up from the heart and is about 2 inches long. The coronary arteries branch off the ascending aorta to supply the heart with blood.
• The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.
• The descending thoracic aorta travels down through the chest. Its small branches supply blood to the ribs and some chest structures.
• The abdominal aorta begins at the diaphragm, splitting to become the paired iliac arteries in the lower abdomen. Most of the major organs receive blood from branches of the abdominal aorta.
Like all arteries, the aorta's wall has several layers:
• The intima, the innermost layer, provides a smooth surface for blood to flow across.
• The media, the middle layer with muscle and elastic fibers, allows the aorta to expand and contract with each heartbeat.
• The adventitia, the outer layer, provides additional support and structure to the aorta.
<span>The emt is appropriately sizing the airway when she measures <u>the distance from the nose to the earlobe.</u>
These emergency medical technicians are obviously trained when it comes to these medical issues, and know how to properly size the airway. In this case, when it comes to the nose airway, this distance between the nose and the earlobe is the way to go.</span>

Explanation:
During a storm, temperatures can drop to a few degrees. This drop in temperature is enough to make the water unfit for fish. As result, the fish die and get washed up on the shore after a storm. The bodies of fish are acclimated to the right temperature to function normally. An increase or decrease in temperature can disrupt the bodily functions of the fish which can be fatal.<span />
Answer:
The temperature is kept at room temperature and mostly preferred to be constant, so that the temperature does't be a variable factor effecting the accuracy of experiment.
Temperature is kept constant to take it as a control factor, so that experimental results are not effected by such outside factors. Such control variables are important in experiments as they minimize the influences from outside.
