Understanding Blood Plasma

The video explains that blood is not blue or red but yellow due to plasma, which makes up 55% of blood and is 90% water. Plasma transports red and white blood cells, nutrients, and heat. It contains proteins like albumin, which maintain osmotic pressure, and electrolytes crucial for nerve function. Plasma also removes waste like urea, filtered by the kidneys. The video concludes by summarizing plasma's roles in maintaining blood pressure, water levels, and body temperature.
