Malpighian Body: Glomerulus and Bowman's Capsule

Biology · Excretory Products and Their Elimination · NEET

The Malpighian body (also called the renal corpuscle) is the filtration head of a nephron. It has two parts working together: the glomerulus, a tuft of capillaries, sits inside a double-walled cup called Bowman's capsule. Memory hook: think "Ball in a Cup" - the glomerulus is the ball of blood vessels, Bowman's capsule is the cup that catches the filtered fluid.

The Malpighian body (renal corpuscle): the glomerulus (capillary "ball" fed by the afferent arteriole) sits inside Bowman's capsule (the "cup"). Blood is filtered here in the kidney cortex, and the filtrate passes into the renal tubule.

Your doubts, answered

Is the Malpighian body the same as the renal corpuscle?

Yes. NCERT gives them as two names for the same structure: "Glomerulus alongwith Bowman's capsule, is called the malpighian body or renal corpuscle." So Malpighian body = renal corpuscle = glomerulus + Bowman's capsule. NEET can use either name in a question, so treat them as identical.

What is the difference between the glomerulus and Bowman's capsule?

The glomerulus is a tuft (bunch) of capillaries formed by the afferent arteriole; blood is filtered here. Bowman's capsule is the double-walled, cup-like start of the renal tubule that encloses the glomerulus and collects the filtrate. Simple way: glomerulus = the blood vessels that leak fluid; Bowman's capsule = the container that catches that fluid. Together they form the Malpighian body.

Is the Malpighian body the same as the Malpighian tubule?

No, and this is a common NEET trap. The Malpighian body (renal corpuscle) is part of the human nephron in the kidney. Malpighian tubules are excretory organs of insects like the cockroach. The names sound alike but the structures and animals are totally different. Watch the wording in the question.

What does the Malpighian body do in urine formation?

It carries out the first step of urine formation: glomerular filtration (ultrafiltration). Blood under pressure in the glomerulus is filtered through three layers into Bowman's capsule, forming a protein-free filtrate. Reabsorption and secretion happen later in the tubule, not here.

Where is the Malpighian body located in the kidney?

In the cortex (outer region) of the kidney. NCERT states the Malpighian corpuscle, PCT and DCT lie in the cortical region, while the loop of Henle dips into the medulla. So if a question asks which nephron parts are cortical, the Malpighian body is one of them.

⚠️ The NEET trap
Students mark that the glomerulus is formed by the efferent arteriole and blood leaves it through the afferent arteriole.
The glomerulus is FORMED by the afferent arteriole (blood enters), and blood LEAVES through the efferent arteriole. Afferent = arrives, Efferent = exits.
🧠 Afferent Arrives, Efferent Exits - the glomerulus is a capillary tuft made by the incoming afferent arteriole.

Real NEET questions

2018

Match the items given in Column I with those in Column II and select the correct option. Column I (Function): a. Ultrafiltration, b. Concentration of urine, c. Transport of urine, d. Storage of urine. Column II (Part): i. Henle's loop, ii. Ureter, iii. Urinary bladder, iv. Malpighian corpuscle, v. Proximal convoluted tubule.

A · a-v, b-iv, c-i, d-ii
B · a-iv, b-i, c-ii, d-iii
C · a-iv, b-v, c-ii, d-iii
D · a-v, b-iv, c-i, d-iii
Solution: Ultrafiltration happens in the Malpighian corpuscle (renal corpuscle), so a-iv. Concentration of urine is done by Henle's loop (b-i), transport of urine by the ureter (c-ii), and storage by the urinary bladder (d-iii). This gives a-iv, b-i, c-ii, d-iii, which is option B. Note the direct link: Malpighian body = site of ultrafiltration.

Frequently asked

Why is it called the Malpighian body?

It is named after Marcello Malpighi, the scientist who first described these microscopic kidney structures. NCERT also lists renal corpuscle as an equal alternative name.

How many layers filter the blood in the Malpighian body?

Three layers: the endothelium of the glomerular capillaries, the epithelium of Bowman's capsule (podocytes), and a basement membrane between them. Blood is filtered so finely that the filtrate is almost protein-free.

Does the Malpighian body reabsorb anything?

No. The Malpighian body only performs filtration. Reabsorption of useful substances happens later in the PCT, loop of Henle, DCT and collecting duct.

Is the filtrate in Bowman's capsule the same as urine?

No. The fluid entering Bowman's capsule is glomerular filtrate, not final urine. Around 99% of it is reabsorbed as it flows through the tubule. Final urine is only about 1.5 litres from 180 litres of filtrate per day.

Why is the Malpighian body important for NEET?

It is a high-frequency topic. NEET repeatedly tests that Malpighian body = glomerulus + Bowman's capsule, that it is the ultrafiltration site, that it lies in the cortex, and it confuses students with Malpighian tubules of insects.
