Question: Buffer salts present in blood are:
Options:
A) Potassium is an essential mineral that plays a key role in maintaining fluid balance, nerve signaling, and muscle contractions. It also helps regulate blood pressure and supports proper functioning of the heart. A deficiency in potassium can lead to symptoms such as muscle weakness, cramps, and irregular heartbeats. Good dietary sources of potassium include bananas, oranges, spinach, potatoes, and tomatoes. The recommended daily intake for adults is approximately 2,600-3,400 milligrams, which can typically be achieved through a balanced diet.
B) Sodium is an essential mineral that plays a key role in maintaining fluid balance, nerve function, and muscle contractions. It is also necessary for the proper functioning of the heart and is involved in the transport of nutrients across cell membranes. A deficiency in sodium can lead to hyponatremia, while excessive intake may contribute to hypertension. The recommended daily intake varies by age, sex, and activity level, with athletes and individuals in hot climates often requiring higher amounts. Sodium is commonly found in table salt (sodium chloride) and is also present in various foods such as processed meats, dairy products, and vegetables.
