2016年10月19日 · The ribs help in the expansion and contraction of the thoracic cavity (though that is primarily the function of the diaphragm) and also protect the lungs and heart. When the diaphragm expands or contracts, the thoracic (chest) cavity expands or contracts, alternately pulling in air (inhalation) or expelling it (exhalation). The ribs, which are flexible, along with the intercostal muscles, help ...

2016年10月16日 · Contraction of the diaphragm flattens it, the volume of thoracic cavity increases, pressure inside lungs diminishes and hence air rushes in: we call it breathing in. During breathing in, the volume of the chest cavity increases due to flattening of diaphragm, and the sternum is also pushed forward due to bucket-handle like movement of ribs.

2016年1月21日 · The sternum and the thoracic vertebrae. The heart and the lungs are protected by the ribcage. The sternum in front, ribs in two side and 12 thoracic vertebrae in the back form the bony cage for protection of these vital organs. Diagram shows the …

2017年12月31日 · Our body would be non functional and we would die if we had no other medical intervention that will keep us alive. The human body without bones is just like an semi-empty sack. Our skeleton is a very rigid structure of bones which provides support for our muscles, skin and its task is also to protect our vital organs.Whithout the bone we would be unable to do anything, beacuse our nerves ...

2016年6月13日 · Probability of at least one correct answer: 1023/1024 Probability of exactly one correct answer: 5/512 The probability of an event occurring can be calculated as "Number of ways the event can occur"/"Total possibilities" As there are two possible results for each of the ten questions, there are 2^10 = 1024 possibilities total. To calculate the probability, then, we only need to know how many ...

2016年5月23日 · There are thirteen organs in the female and twelve organs in the male found underneath the rib cage. The smaller lobe of the liver, spleen, pancreas, stomach, left adrenal gland, left kidney, left ureter, left Fallopian tube (female) left ovary (female), left testis (male), the descending colon, sigmoid colon, rectosigmoid colon, and the rectum are all on the left side of the body underneath ...

2018年5月11日 · True A radical expression is any expression containing a radical sign (sqrt). So the equation: 5 + sqrt(2x) = 18 Is a radical expression.

Mass is conserved rather than created or destroyed so when a chemical equation is written, it must be balanced so that there is the same amount of reactants going in as yielded product. The equation is balanced by changing the scalar numbers that precede each part of the equation.

In this case, two of our statements from the definition are true: specifically, the third and the sixth. Therefore, we say that: #f(x) = 1/x# has a vertical asymptote at #x=0#. See image below. Sources: Stewart, James. Calculus. #6^(th)# ed. Belmont: …

2014年4月27日 · Rutherford's experiment showed that the atom does not contain a uniform distribution of charge. > Thomson's plum pudding model viewed the atom as a massive blob of positive charge dotted with negative charges. A plum pudding was a Christmas cake studded with raisins ("plums"). So think of the model as a spherical Christmas cake. When Rutherford shot α particles through gold foil, he found ...
