Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The Bowman’s capsule, glomerulus, and collecting tubule are all part of the
A
nervous system
B
kidney
C
nephron
D
excretory system
Explanation: 

Detailed explanation-1: -Bowman’s capsule is a part of the nephron which is a part of your kidney. The nephron is the filtering unit of your kidney. There are about 1 million nephrons in each kidney. Every nephron has a glomerulus, which is a group of tiny blood vessels and the starting point for filtering waste products out of your blood.

Detailed explanation-2: -Each nephron is composed of a renal corpuscle (glomerulus within Bowman’s capsule), a proximal tubule (convoluted and straight components), an intermediate tubule (loop of Henle), a distal convoluted tubule, a connecting tubule, and cortical, outer medullary, and inner medullary collecting ducts.

Detailed explanation-3: -The basic physiology of a nephron within a kidney: The labels are: 1. Glomerulus, 2. Efferent arteriole, 3. Bowman’s capsule, 4.

Detailed explanation-4: -Collecting tubules are not part of the nephron. The epithelium of these tubules consist of cuboidal or columnar cells. They empty into collecting ducts that are easy to recognise, because they have large lumens, with pale staining columnar epithelium.

Detailed explanation-5: -The nephron’s primary function is to filter waste from the blood. The nephron has three major parts: the glomerulus, the Bowman’s Capsule, and the tubules, which consist of the promimal and distal tubule and the Loop of Henle.
