What is a nephron?
A
a network of capillaries and tubules where filtration of blood occours
B
a big tube
C
two big organs
D
a tube that filters wastes out of the body
Explanation: 

Detailed explanation-1: -The nephron is the minute or microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman’s capsule. The renal tubule extends from the capsule.

Detailed explanation-2: -Peritubular capillaries are tiny blood vessels in your kidneys. They filter waste from your blood so the waste can leave your body through urine (pee).

Detailed explanation-3: -Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.

Detailed explanation-4: -The correct option is A Glomerulus. In a nephron, glomerulus is a network of small blood vessels (capillaries) located at the beginning of the nephron in the kidney. It helps in the filtration of blood. It is enclosed by a cup shaped structure called Bowman’s capsule.

Detailed explanation-5: -The filtration of blood is carried out in renal corpuscle. Glomerulus and Bowman’s capsule together form the renal corpuscle. Glomerulus is a group of blood capillaries that is present in the Bowman’s capsule of nephrons and is the seat, where the process of ultrafiltration takes place.
