(ii) Name the chamber of the heart through which blood in structure A last passed.​

Answer 1

Answer:

The kidneys are bilateral organs placed retroperitoneally in the upper left and right abdominal quadrants and are part of the urinary system. Their shape resembles a bean, where we can describe the superior and inferior poles, as well as the major convexity pointed laterally, and the minor concavity pointed medially.

Explanation:

The main function of the kidney is to eliminate excess bodily fluid, salts and byproducts of metabolism – this makes kidneys key in the regulation of acid-base balance, blood pressure, and many other homeostatic parameters.
