B. At the same level
C. Left kidney at a higher level than the right one
D. Right kidney at a higher level than the left one

Answer 1

Kidneys are a pair of bean-shaped organs that are present on either side of the spine. It helps in the removal of wastes and maintains the levels of electrolytes. It turns waste materials into urine that collects in the kidney pelvis that drains into the bladder through ureters.

Complete answer: A pair of kidneys is a part of the excretory system that is located on either side of the spine. It helps in blood filtration and removes the waste produced. They are found along the posterior muscular wall of the abdominal cavity in the retroperitoneal space of the body. The right kidney is located inferior to the left kidney due to the larger size of the liver on the right side of the human body. They are bean-shaped organs that help in blood filtration before it sends to the heart. It performs many crucial functions such as maintaining overall fluid balance. Each kidney has millions of nephrons. Nephrons are the cells of the kidney which are composed of the renal corpuscle and a renal tubule. The renal corpuscle is also known as the Malpighian body. It consists of a cup-like double-walled structure known as Bowman’s capsule and the bunch of capillaries is known as the glomerulus.
Hence, the correct option is (C)-Left kidney at a higher level than the right one.

Note: The kidney can become damaged from a physical injury or any disease such as diabetes, high blood pressure, and other disorders. They are the common causes of kidney failure. It can be treated with temporary and permanent methods. Dialysis is a temporary method that helps to remove water and waste substances by circulating blood through an external filter known as a dialyzer. The dialyzer contains a semi-permeable membrane. It is also known as hemodialysis. It is effective only for a short time.
