Question

I am a straw-colored liquid and I make up 55% of your blood. I am mostly made of water. What am I?

Answer 1

Hint: Humans, animals, and many invertebrates rely on haemoglobin to transport oxygen and, to a lesser extent, carbon dioxide throughout their circulatory systems. However, blood is more than just proteins. Blood is a term that refers to the liquid that circulates through the vessels and comprises plasma (the liquid portion, which contains water, proteins, salts, lipids, and glucose) as well blood cells (red and white cells) and platelets (cell fragments).

Complete answer:
Plasma, the straw-colored liquid that transports your red, white, and platelets, makes about 55 percent of your blood. Antibodies and other crucial proteins are also found in plasma.
Plasma and cells combine to form blood.
Erythrocytes (red blood corpuscles), leucocytes (white blood corpuscles), and thrombocytes (platelets) are three different types of cells with diverse activities.
Plasma is the straw-colored liquid in which all cells float. Plasma is almost entirely made up of water, with dissolved proteins, glucose, clotting factors, and carbon dioxide dissolved in it.
It can be isolated from whole blood via centrifugation, which involves spinning whole blood in a centrifuge with an anticoagulant. The lighter plasma forms the upper yellowish layer, while the denser blood cells create the bottom layer. To retain the functionality of the various clotting factors and immunoglobulins, the plasma is frozen within 24 hours.
It must be thawed before use and has a one-year shelf life. Interestingly, while O- is the ideal universal blood donor, AB blood group plasma is the most desired since it contains no antibodies, making it suitable for everyone without risk of an unfavourable reaction.

Note:-
Adults between the ages of 18 and 75 who match the donation eligibility criteria can donate blood. The process is relatively painless and safe. You will donate approximately 470ml of whole blood during a normal donation. This represents around 8% of the average adult's blood volume. This volume is replaced in 24 to 48 hours, and red blood cells are replenished in 10 to 12 weeks.
