Plasma

The video explains that plasma, the yellowish fluid in blood, makes up 55% of blood volume and is 90% water. Plasma transports red and white blood cells, nutrients, and heat. It contains proteins like albumin, globulin, and fibrinogen, which help in defense and maintaining osmotic pressure. Plasma also carries electrolytes, enzymes, and hormones, and plays a role in waste removal, such as urea, filtered by the kidneys. Overall, plasma is crucial for maintaining blood pressure, water levels, and body temperature.
