Metabolic Acidosis: Primary Bicarbonate Deficiency

Source: OpenStax Anatomy and Physiology OpenStax Anatomy and Physiology Metabolic acidosis occurs when the blood is too acidic (pH below 7.35) due to too little bicarbonate, a condition called primary bicarbonate deficiency. At the normal pH of 7.40, the ratio of bicarbonate to carbonic acid buffer is 20:1. If a person’s blood pH drops below … Continue reading Metabolic Acidosis: Primary Bicarbonate Deficiency

What is Ketoacidosis?

Dehydration may be severe in diabetic ketoacidosis, and intravenous fluids are usually needed as part of its treatment. By Harmid - Own work, Public Domain, https://commons.wikimedia.org/w/index.php?curid=4657586 OpenStax Anatomy and Physiology Diabetic acidosis, or ketoacidosis, occurs most frequently in people with poorly controlled diabetes mellitus. When certain tissues in the body cannot get adequate amounts of glucose, they … Continue reading What is Ketoacidosis?

Renal Regulation of Acid-Base Balance

Tubular cells are not permeable to bicarbonate; thus, bicarbonate is conserved rather than reabsorbed. Source: OpenStax Anatomy and Physiology OpenStax Anatomy and Physiology The renal regulation of the body’s acid-base balance addresses the metabolic component of the buffering system. Whereas the respiratory system (together with breathing centers in the brain) controls the blood levels of … Continue reading Renal Regulation of Acid-Base Balance

Respiratory Regulation of Acid-Base Balance

The respiratory system can reduce blood pH by removing CO2 from the blood. Source: OpenStax Anatomy and Physiology OpenStax Anatomy and Physiology The respiratory system contributes to the balance of acids and bases in the body by regulating the blood levels of carbonic acid. CO2 in the blood readily reacts with water to form carbonic … Continue reading Respiratory Regulation of Acid-Base Balance

The Regulation of Sodium and Potassium

Aldosterone, which is released by the adrenal gland, facilitates reabsorption of Na+ and thus the reabsorption of water. Source: OpenStax Anatomy and Physiology OpenStax Anatomy and Physiology Sodium is reabsorbed from the renal filtrate, and potassium is excreted into the filtrate in the renal collecting tubule. The control of this exchange is governed principally by … Continue reading The Regulation of Sodium and Potassium
