Question

The fluid part of blood is called as
A. Pulse
B. Plasma
C. Haemoglobin
D. Platelets

Answer 1

Blood is a constantly flowing liquid that provides sustenance, oxygen, and waste removal to the body. Blood is mostly fluid, but it contains numerous cells and proteins that make it "thicker" than pure water. The heart's pumping activity circulates blood throughout the body through veins. Venous blood delivers carbon dioxide, a waste product of digestion created by cells, from the tissues to the lungs to be exhaled, whereas vascular blood transports oxygen from breathed air to the body's tissues.

Complete answer:
Option A: The heart rate, or the number of times the heart beats in one minute, is called pulse. Pulse rates differ from one person to the next. As a person is at rest, their pulse is lower, and when they exercise, their pulse rises (more oxygen-rich blood is needed by the body when you exercise).
So, option A is not correct.
Option B: One half of blood is made up of red blood cells, white blood cells, and platelets, which are solid parts of blood, and the other half is made up of water, salts, and proteins, which are fluid parts of blood. Plasma is the liquid component of blood.
So, option B is correct.
Option C: Hemoglobin is an iron-containing oxygen-transport metalloprotein found in practically all vertebrates' red blood cells as well as some invertebrates' tissues. Blood contains haemoglobin, which transports oxygen from the lungs or gills to the rest of the body.
So, option C is not correct.
Option D: Red blood cells, white blood cells, and platelets make up the solid part of your blood. When you have a cut or a wound, platelets assist the blood clot.
So, option D is not correct.

So, option B is the correct answer.

Additional information:
It's important to understand that serum is plasma without the clotting components. There are a total of thirteen identified clotting factors, with factor six no longer being considered. Fibrinogen is the first clotting factor. It's worth noting that these clotting factors are only seen in our blood plasma, but they're all made in the liver.

Note:
Plasma refers to the fluid portion of the blood. It is a moderately viscous fluid that makes up $55 - 58$ percent of total blood volume. The following are the characteristics of fluid plasma:
1. Aesthetically, it has a straw-colored appearance.
2. $91.5$ percent of it is made up of water.
3. Dissolved solutes, such as clotting factors and plasma proteins, are present in $- 8.5$ percent.
