Filtration of the blood in nephrons allows blood plasma to pass through without ____
A
blood cells and proteins
B
macro molecules
C
Glucose
D
Ammonia
Explanation: 

Detailed explanation-1: -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. Each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes.

Detailed explanation-2: -Blood enters the glomerulus under high pressure, forcing substances across the leaky endothelial-capsular membrane into the nephron. This membrane acts like a sieve allowing small substances to be filtered into the nephron, whilst large molecules such as plasma proteins remain within the blood.

Detailed explanation-3: -Each of the nephrons contain a filter called the glomerulus (pronounced: gluh-MER-yuh-lus). The fluid that is filtered out from the blood then travels down a tiny tube-like structure called a tubule (pronounced: TOO-byool). The tubule adjusts the level of salts, water, and wastes that will leave the body in the urine.

Detailed explanation-4: -The kidneys remove waste products called urea from the blood through tiny filtering units called nephrons.
