Answer:
This is due to the property of contractility.
Answer: Oxygen gets carried away on the red blood cells, and carbon dioxide is expelled into the air. The exchange of these two gases takes place without much fanfare when the body is at rest.
A rapid rate of breathing can occur normally after exercise. In addition, panic states and high altitude climbs can also raise the respiratory rate. When these conditions occur, individuals may have a variety of symptoms related to pH changes in their bodies caused by the hyperventilation
Your body needs oxygen to breathe, which it takes from the air around you, into your lungs, to your heart - where it is pumped to your muscles and organs. When the oxygen is used by your muscles, carbon dioxide is produced, which needs to be removed. So as the new oxygen goes into your muscles, the carbon dioxide from the last pump is taken out, where it is sent all the way back round to the heart, and then back to your lungs, and out of your mouth, back into the air.
So, rebreathing breathed air increases the carbon dioxide concentration in you blood, triggerring you body's response of increased breathing in an attempt to regain oxygen and get rid of carbon dioxide.
Explanation:
X-ray radiography is the imaging technique uses radiation that is emitted from the material being imaged.
<h3>What is X-ray?</h3>
This is referred to as a penetrating form of high-energy electromagnetic radiation and is used for imaging.
The rays penetrate objects and body parts and create an image which is often used for diagnostics in healthcare centres which makes option A the most appropriate choice.

<span>When light enters the eye, it first passes through the cornea, then the aqueous humor, lens and vitreous humor. Ultimately it reaches the retina, which is the light-sensing structure of the eye. The retina contains two types of cells, called rods and cones. Rods handle vision in low light, and cones handle color vision and detail. When light contacts these two types of cells, a series of complex chemical reactions occurs. The chemicals causes electrical impulses that are transmitted to the brain and interpreted as light.</span>
