How do the kidneys filter the blood?
Answers
When the blood flows into the renal artery, it arrives at a structure inside the kidney called a glomerulus, which is a group of closely packed capillaries. Small molecules (e.g. glucose and salts) pass out of the glomerulus and into the Bowman's capsule, while large molecules (e.g. red blood cells and fibrinogen) stay in the blood.
The glucose, some salts and most of the water are then reabsorbed into the blood capillaries. The fluid, known as urine, containing urea and excess salts dissolved in water flows down the ureter and is stored in the bladder.
Answer:
Explanation:
Each kidney contains up to a million functioning units called nephrons. A nephron consists of a filtering unit of tiny blood vessels called a glomerulus attached to a tubule. When blood enters the glomerulus, it is filtered and the remaining fluid then passes along the tubule.
