Study Notes
Blood Components and Properties
- Blood components, including plasma, red blood cells, white blood cells, and platelets, are found in the circulatory system, specifically in the blood vessels, heart, and lymphoid organs.
Blood Characteristics
- Blood is more viscous and denser than water, with a specific gravity of approximately 1.06, which affects its flow and behavior in the body.
Blood Cell Sedimentation
- Blood cells sediment or settle to the bottom of a tube due to the force of gravity, which causes them to separate from the plasma.
Hematopoiesis
- Hematopoiesis, the process of blood cell production, occurs in the bone marrow, specifically in the red bone marrow of flat bones, such as the sternum, ribs, and pelvis, and in the vertebrae.
Blood Composition
- Blood constitutes approximately 7-8% of an individual's total body weight, which is a significant proportion of the body's total mass.
