Final answer:
The false statement about blood is that it has a neutral pH of 7.0, when in fact, it typically ranges between 7.35 and 7.45, slightly basic. Blood is thicker than water due to its cellular and protein content and makes up approximately 4-6 liters of the human body.
Step-by-step explanation:
The false statement about blood is b. Blood normally has a neutral pH of 7.0. In reality, blood has a pH that ranges between 7.35 and 7.45, which makes it slightly basic (alkaline), compared to neutral water which has a pH of 7.0.
Blood plasma constitutes more than half of the blood's volume and contains about 92 percent water, along with proteins and dissolved substances. Blood indeed is thicker than water due to these proteins and formed elements, such as erythrocytes (red blood cells), leukocytes (white blood cells), and platelets, making it slightly more viscous. An adult human body typically holds about 4-6 liters of blood, and the average temperature of blood is lower than 100.4oF, usually close to the normal body temperature of approximately 98.6oF.
