Question

The functional unit of the kidney is neurons.
(a) True
(b) False

Answer 1

Hint: These are small tube-like projections inside the kidneys. They are the basic filtering units of kidneys. They are present about millions in each human kidney. It assists in blood filtration and the formation of urine.

Complete answer:
The functioning component of the kidney is the nephron. The nephrons are the microscopic structural and located in the cortex and medulla of the kidney. Each kidney consists of many nephrons which play a big role within the filtration and purification of blood. The nephron is separated into two main portions, which are the glomerulus and the renal tubule, and helps in the removal of excess waste from the body. It also regulates the concentration of minerals such as sodium by filtering the blood and reabsorbing the important nutrients.
The mammalian nephron is a long tube-like structure, its length differing from 35 to 55 mm long. At one end, the tube is closed, folded, and lengthened, into a double-walled. The cuplike structure is known as the Bowman’s capsule or renal corpuscular capsule, which encloses a cluster of microscopic blood vessels called the glomerulus. This capsule and glomerulus together constitute the malpighian body.
Whereas neurons are the building blocks of the nervous system. They get and transmit signals to various parts of the body. This is administered in both physical and electrical forms. There are several different types of neurons that facilitate the transmission of data.

So, the correct answer is ‘False’.

Note:
Each kidney possesses a large number of nephrons, approximately 1-1.5 million. The four mechanisms of the kidney are filtration, reabsorption, secretion, and excretion. The urine formed in each kidney enters an extended tube called the ureter. From the ureter, it gets transported to the bladder then into the urethra.
