What are the 4 components of Blood and their percentages?
Plasma constitutes 55% of total blood volume.
White Blood Cells.
There are between 6,000 and 8,000 white cells per cubic millimetre of blood.
Platelets, or thrombocytes, are smaller than the red and white blood cells.
Red Blood Cells..
What are the 3 types of blood?
Blood is made mostly of plasma, but 3 main types of blood cells circulate with the plasma:Platelets help the blood to clot. Clotting stops the blood from flowing out of the body when a vein or artery is broken. … Red blood cells carry oxygen. … White blood cells ward off infection.
What are the 2 parts of blood?
Blood is classified as a connective tissue and consists of two main components:Plasma, which is a clear extracellular fluid.Formed elements, which are made up of the blood cells and platelets.
What is the largest artery in the body?
All arteries of the systemic circulation branch from the aorta (this is the largest artery of the body, with a diameter of 2-3 cm), and divide into progressively smaller vessels.
What are the 7 formed elements of blood?
The three classes of formed elements are the erythrocytes (red blood cells), leukocytes (white blood cells), and the thrombocytes (platelets).Erythrocytes (red blood cells) Erythrocytes, or red blood cells, are the most numerous of the formed elements. … Leukocytes (white blood cells) … Thrombocytes (platelets)
What are the 7 types of blood cells?
Blood cells. Blood contains many types of cells: white blood cells (monocytes, lymphocytes, neutrophils, eosinophils, basophils, and macrophages), red blood cells (erythrocytes), and platelets. Blood circulates through the body in the arteries and veins.
What is the function of RBC?
What Is the Function of Red Blood Cells? Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.

What are the five major components of blood?
The different components that make up blood. Plasma, white blood cells, red blood cells, platelets.
Which blood component has the shortest lifespan?
White blood cells are made in the bone marrow. They are stored in your blood and lymph tissues. Because some white blood cells have a short life of 1 to 3 days, your bone marrow is always making them.

What is the lifespan of blood?
approximately 120 daysHuman red blood cells are formed mainly in the bone marrow and are believed to have an average life span of approximately 120 days.
What is the shortest living cell in the human body?
white blood cellsThe shortest living cells are some of the white blood cells, which are the like the sentry system in the blood, looking out for disease and helping the body fight infection. Some of these will only last a few hours, certainly less than a day.
Which blood cells are the largest?
Monocytes are the largest cells of the blood (averaging 15–18 μm in diameter), and they make up about 7 percent of the leukocytes. The nucleus is relatively big and tends to be indented or folded rather than multilobed.
What is the main function for blood in the body?
transporting oxygen and nutrients to the lungs and tissues. forming blood clots to prevent excess blood loss. carrying cells and antibodies that fight infection. bringing waste products to the kidneys and liver, which filter and clean the blood.
What are the major components of whole blood?
Whole blood contains red cells, white cells, and platelets (~45% of volume) suspended in blood plasma (~55% of volume). Whole Blood is the simplest, most common type of blood donation.
What makes the blood look red?
