Blood: The Four Major Components

From the start of independence, the question of the process of career selection has stumbled teens across the globe. Whether the outcome be based on the amount of money, the location, or even the very few who find their true passion, no one has a definitive idea on what they will pursue. Richard Van Camp’s main character, Leo, is faced with the same dilemma. Van Camp's short story, “The Strongest Blood”, explores the use of symbolism, brought through by money, the conflicts in which influence career decision, and the use of pathos to evoke an emotional connection to the reality of the world.

As the concentration of hemoglobin in the Red Blood Cells falls below normal, the total Red Blood Cell count consequently decreases. Therefore, oxygen cannot be adequately carried. (http://www.mayohealth.org/mayo/pted/htm/iron.htm).

“Erythrocytes contain haemoglobin, an important respiratory pigment that is essential for human life” (Strech, Beryl; Whitehouse, Mary;, 2010) Haemoglobin is very important because it is an iron-containing protein.

The blood contains the oxygen, platelets, nutrients, red and white blood cells, hormones which are all important materials for metabolism.

The general charactertics of blood are color, composition, and pH. The composition of blood is determined by collecting blood from a person then it’s placed in a centrifuge which shows plasma is 55% of whole blood and 45 % is erythrocytes. Another name for red blood cells is erythrocytes which are small sacs of blood that carry oxygen and

 Once the oxygen-depleted cells are in the lungs, they travel into the alveoli where they lose their CO2 and trade it for oxygen. The oxygen is able to stay with the red blood cells because the cell have hemoglobin which is a protein which binds with oxygen.

To name the two major components of blood and state their average percentages in whole blood.

Blood is a mixture of liquids and solids. Blood contains plasma, serum, red blood cells, white blood cells proteins and more. Blood does not stay in liquid form for a long time after being exposed from your body, due to clotting. It clots a few minutes forming a dark red, gel-like substance that becomes more solid time passes. Blood clots can tell an attack was prolonged or the victim was bleeding for a significant period after being injured.

Blood has many functions and is a complex structure of cells and fluid. It helps fight bacteria, protect the body from infection, carry valuable sources of minerals and nutrients around the body, dispose of waste materials, keeps the body temperature regulated and helps with glandular distribution of hormones and enzymes.

Explanation: A). Blood carries oxygen from the lungs to the cells of organs and tissues and carbon dioxide from those organs and tissues to the lungs inside our body.

Blood is made up of straw coloured plasma, the matrix, in which various types of blood are carried. Plasma is mainly water where substances are carried such as oxygen and carbon dioxide, nutrients such as glucose and amino acids, salts, enzymes and hormones. Also there is a combination of important proteins which help with blood clotting, transport,

Haemoglobin is a protein molecule found in red blood cells (RBC). Its role in the body is to transport oxygen from the lungs to the body 's tissues and then returns carbon dioxide from the tissues back to the lungs. The transportation of oxygen is only possible when haemoglobin (Hb) within the RBC binds to oxygen. (Martini & Nath, 2006)

The second crucial function of hemoglobin according to Keohane et al. (2016) together with McPherson & Pincus (2017) is the transport of carbon dioxide (Figure 9). They stated that: “In venous blood, the carbon dioxide diffuses into the red blood cells and combines with water to form carbonic acid (H2CO3). This reaction is facilitated by the RBC enzyme carbonic anhydrase. Carbonic acid then dissociates to release H+ and bicarbonate (HCO3-).

Red blood cells (also referred to as erythrocytes) are the most common type of blood cell and the vertebrateorganism's principal means of delivering oxygen (O2) to the body tissues via the blood flow through thecirculatory system. They take up oxygen in the lungs or gills and release it while squeezing through the body'scapillaries.

The other components of the blood such as the erythrocytes and leukocytes occupy the remaining 1% of the total blood volume in the entire circulatory system.
