The correct answer is: C. Both 1 and 2
The kidneys are two bean-shaped organs located in the lower back. They filter waste products from the blood and produce urine. Urine is a waste product that contains water, salt, and other waste products.
The kidneys are responsible for many important functions, including:
- Filtering waste products from the blood
- Regulating blood pressure
- Producing red blood cells
- Maintaining a healthy balance of fluids and electrolytes
- Excreting waste products in the form of urine
The kidneys are made up of millions of tiny units called nephrons. Nephrons are responsible for filtering the blood and producing urine.
The nephron has two main parts:
- The glomerulus
- The tubule
The glomerulus is a ball of capillaries that filters the blood. The tubule is a long, winding tube that reabsorbs water and other nutrients from the filtered blood.
The filtered blood is then sent back to the body through the renal vein. The reabsorbed water and nutrients are sent back to the blood through the renal artery.
Statement 1 is correct because after the waste is removed in the kidney the clean blood is sent back through renal artery.
Statement 2 is correct because from Bowman’s capsule, the filtered liquid passes through tiny tubes where much of the glucose is reabsorbed and sent back to the blood in the renal vein.
Therefore, both statements 1 and 2 are correct.
