Capitolo 19, Problema 3
Blood temperature is approximately ___, and blood pH averages ___.
(a) 36 °C, 7.0
(b) 39 °C, 7.8
(c) 38 °C, 7.4
(d) 37 °C, 7.0
Guida verificata passo dopo passo1
Step 1: Understand the normal physiological values for blood temperature and pH. Blood temperature is typically close to the body's core temperature, which is around 37 °C in a healthy adult.
Step 2: Recall that blood pH is tightly regulated to maintain homeostasis, usually slightly alkaline, with a normal average value around 7.4.
Step 3: Compare the given options with these known physiological norms: temperature near 37 °C and pH near 7.4.
Step 4: Eliminate options that have blood temperature or pH values significantly different from these normal ranges (e.g., 39 °C or pH 7.8 are outside normal limits).
Step 5: Select the option that best matches the typical blood temperature and pH values, which are approximately 37 °C and 7.4 respectively.

Blood pH and Its Regulation
Blood pH measures the acidity or alkalinity of blood, normally averaging about 7.4, which is slightly alkaline. Maintaining this pH is vital for proper cellular function and is regulated by buffer systems, respiration, and renal function.
