The Role of Plasma in the Circulatory System
What is the matrix of blood called?
A. Buffy coat
B. Plasma
C. Erythrocyte
D. Lymphocyte
E. Formed Elements
Answer:
The matrix of blood, which is fluid, is called plasma.
Plasma is the liquid component of blood that carries the formed elements throughout the body within the cardiovascular system. It is primarily made up of water and serves as a medium for the transportation of nutrients, gases, waste products, hormones, and proteins.
The formed elements of blood, including red blood cells (erythrocytes), white blood cells (leukocytes), and platelets, are suspended in the plasma. Each of these elements plays a crucial role in various bodily functions.
Red blood cells, or erythrocytes, are responsible for transporting oxygen from the lungs to tissues throughout the body and carrying carbon dioxide back to the lungs for exhalation. White blood cells, or leukocytes, are key components of the immune system and help the body fight off infections and diseases. Platelets are essential for blood clotting, preventing excessive bleeding when a blood vessel is injured.
In summary, plasma is vital for maintaining proper blood circulation and supporting the functions of the formed elements in the circulatory system.
