Metabolic acidosis is when the kidneys produce too much hydrogen or retain too much hydrogen which leads to an increase in carbonic acid production. Or the kidneys excrete too much base.
<h3>What is metabolic acidosis?</h3>
- The primary function of the kidney is to purge toxins from the blood and convert waste products into urine.
- Around 160 grams of weight and one to one and a half litres of urine are excreted daily by each kidney.
- When the kidneys do not properly eliminate acids from the blood into the urine, renal tubular acidosis (RTA) ensues.
- The result is an excessively high blood acid level, or acidosis.
- While having some blood acid is natural, having too much acid can cause numerous biological functions to become unbalanced.
- When there is too much acid in the body's fluids, it is called acidosis.
- When your kidneys and lungs are unable to maintain a healthy pH level in your body, acidosis results.
- Acid is created by numerous bodily activities.

Answer:
The correct answer is - tight junctions.
Explanation:
Tight junctions are one of the cell-cell junctions that make a barrier to the passage of material which is a present in epithelia. This barrier is impermeable to most of the materials with soluble molecules. This barrier is made up of the occludin and claudin proteins.
Tight epithelia have tight junctions and examples of such junctions are the distal convoluted tubule or DCT, and the collecting duct of the nephron in the kidney.
Thus, the correct answer is - tight junctions.
Answer:
Explanation:
Bones are organs composed of hard living tissue providing structural support to the body – it's scaffolding. It is a hard matrix of calcium salts deposited around protein fibers. Minerals make bone rigid and proteins (collagen) provide strength and elasticity. ... The outer layer of bone is called Cortical bone.
