The partial pressure of carbon dioxide (pCO\u2082<\/strong>) is greatest in the tissues of the body<\/strong>, particularly in metabolically active cells.<\/p>\n\n\n\n Partial pressure refers to the pressure exerted by a specific gas within a mixture of gases. In the human body, carbon dioxide (CO\u2082<\/strong>) is produced as a waste product of cellular respiration. Cells break down glucose and oxygen in the mitochondria to generate ATP, releasing CO\u2082 as a byproduct.<\/p>\n\n\n\n Since metabolism is constant, CO\u2082 accumulates in the tissues, leading to the highest partial pressure of CO\u2082 in body tissues<\/strong>. This creates a pressure gradient that allows CO\u2082 to diffuse from cells into the surrounding capillaries.<\/p>\n\n\n\n In contrast, the partial pressure of CO\u2082 is lower in arterial blood<\/strong> (around 40 mmHg) and even lower in the alveoli of the lungs (about 35-45 mmHg). This pressure difference facilitates the movement of CO\u2082 from the bloodstream into the lungs, where it is expelled during exhalation.<\/p>\n\n\n\n Thus, the order of CO\u2082 partial pressure from highest to lowest is<\/strong>:<\/p>\n\n\n\n This efficient gas exchange process ensures that CO\u2082 does not accumulate dangerously in the body, maintaining homeostasis and proper pH balance.<\/p>\n\n\n\n The partial pressure of carbon dioxide is greatest in The correct answer and explanation is : The partial pressure of carbon dioxide (pCO\u2082) is greatest in the tissues of the body, particularly in metabolically active cells. Explanation (300 words) Partial pressure refers to the pressure exerted by a specific gas within a mixture of gases.
