Questions: Which of the following statements is NOT TRUE? The temperature of blood is typically higher. The salt concentration of blood is about 0.85% to maintain osmotic pressure. Blood is a liquid connective tissue and constitutes a significant portion of a person's overall body weight. The homeostatic range for blood pH is 7.35 to 7.45, making it slightly alkaline. Blood is 4-5 times more viscous than water, making it harder for the heart to pump than water.

The answer is the second one: "The salt concentration of blood is about . $85 \%$ maintain osmotic pressure."

Explanation for each option:

1. "The temperature of blood is typically higher" - This statement is true. The temperature of blood is generally around 38°C (100.4°F), which is slightly higher than the average body temperature.

2. "The salt concentration of blood is about . $85 \%$ maintain osmotic pressure." - This statement is NOT TRUE. The salt concentration of blood is actually about 0.85% (or 0.9%) to maintain osmotic pressure, not 85%.

3. "Blood is a liquid connective tissue and consti person's overall body weight." - This statement is true. Blood is indeed a liquid connective tissue and constitutes about 7-8% of a person's overall body weight.

4. "The homeostatic range for blood pH is 7.35 t slightly alkaline." - This statement is true. The normal pH range for blood is between 7.35 and 7.45, which is slightly alkaline.

5. "Blood is 4-5 times more viscous than water a pump than water." - This statement is true. Blood is indeed 4-5 times more viscous than water, making it more challenging for the heart to pump.

Summary: The statement that is NOT TRUE is the second one regarding the salt concentration of blood. The correct salt concentration is about 0.85%, not 85%.
