<u>Answer</u>:
Different type of the same procedure that takes the place of the kidneys and cleans the blood are mutually all known as osmoregulation.
<u>Explanation</u>:
Along with kidney there are other organs which helps the body to purify blood. These organs are lungs which exchanges carbon dioxide with oxygen and skin which helps in excreting the extra salt concentration from the body. In invertebrate animals the kidney is not present but osmoregulation takes place with the help of organelles and organs like vacuoles, nephridia, antennal glands, salt glands and malpighian tubules.
Answer: External auditory canal
Explanation: External auditory canal or external acoustic meatus is a passage that leads from the outside head to the eardrum of ear.
The structure of external auditory canal is same in all the mammals, slightly curved tube extending from the outer ear towards eardrum.
This canal is almost 2.5 cm in length with some hairs and sweat glands on the outer side to prevent insects from entering into the ear.
So, the correct answer is external auditory canal.
Answer:
The correct answer is: E) a bruit sound when auscultated with a stethoscope.
Explanation:
Mitral valve regurgitation is a condition in which the mitral valve - <em>responsible for the blood flow from the left atrium to the left ventricle </em>- doesn't close as tightly as it should, which can result in backward blood flow. If the condition worsens, this defect can lead to heart failure.
Mitral valve regurgitation may not have symptoms at first but, as the condition progresses, shortness of breath, fatigue, and palpitations can occur. When auscultated with a stethoscope, a bruit sound can be heard, which corresponds to the abnormal blood flow that is occurring.
