Erythrocytes
A Red blood cell also known as an erythrocytes are a vital part of your body that helps you live. The red blood cell is a disk shaped cell that caries oxygen to tissues like you brain. Erythrocytes are one of the smallest cells in your body. And red blood cells make up over 99% of blood cells. Also, there are many different types of disease that affect erythrocytes.
The red blood cell is a disk shaped cell that is compressed in the center, unlike a normal human cell the red blood cell does not have a nucleus which means that they do not have any DNA. The red blood cell contains hemoglobin, hemoglobin is made of iron and protein. In one red blood cell about 280 hemoglobin. The color of your erythrocytes is due to hemoglobin, when hemoglobin has oxygen it appears scarlet which a red-orange color is. When oxygen has just left the cell it appears a slightly darker color. The red blood cell carries oxygen to your tissues the red blood cell does this so well because oxygen moves so well through the membrane. Also erythrocytes are very flexible so they can move so they can move through narrow capillaries.

The circulatory system is a system of organs that pump blood, using your heart. The right and left side of your heart are two different pumps but they both move blood through your body. Erythrocytes are carried through a liquid in the blood called plasma. Other cells are also carries through the blood like leukocytes and thrombocytes. Although red blood cell are 99 percent of all the blood cells in blood. Each average adult has 20-30 trillion red blood cells in their body, those who live in higher altitude tend to have more erythrocytes than those living in lower altitudes, the reason why people living in higher altitude have more erythrocytes is, because in higher altitudes air is thinner, so you need more
In this experiment, we determined the isotonic and hemolytic molar concentrations of non-penetrating moles for sheep red blood cells and measured the absorbance levels from each concentration. The results concluded that as the concentration increased the absorbance reading increased as well. A higher absorbance signifies higher amounts of intact RBCs. The isotonic molar concentration for NaCl and glucose is 0.3 M. The hemolysis molar concentration for NaCl and glucose is 0.05 M. Adding red blood cells to an isotonic solution, there will be no isotonic pressure and no net movement. The isotonic solution leaves the red blood cells intact. RBC contain hemoglobin which absorbs light, hemoglobin falls to the bottom of the tube and no light is absorbed. Determining the isotonic concentration of NaCl and glucose by finding the lowest molar concentration. In contrast to isotonic molar concentration, hemolysis can be determined by finding the
The body is composed of cells, which form the basic unit of life. Unique cells found in the body are the stem cells. These cells are biological cells that are not specialized for particular functioning in organisms. They can be distinguished since they have the ability to differentiate or divide into multiple body cells, and their ability to replicate self. They are unique in the way they can renew themselves by undergoing cell division when inactive for a long period. It is also possible to induce stem cells to organs or tissue cells under some conditions. When the cells divide, they replenish the cells in a living organism. They serve as an internal system that repairs and replaces the tissues that are worn out.1 Dividing cells may remain as stem cells or become specialized in their functions, for instance red blood cells, brain or muscle cells.
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
Red blood cells deliver the oxygen to the muscles and organs of the body.
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
The process by which Erythropoietin regulates red blood cell production is called Erythropoiesis. When the kidneys and liver detects hypoxia in the blood Erythropoietin is released which stimulates red bone marrow to increase red blood cell production allowing for greater oxygen transport throughout the bloodstream(Martini, Ober & Nath 2014). The following diagram illustrates the cycle of Erythropoiesis when oxygen levels in the blood stream increase and decrease.
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.

The body's blood consists of many components, red blood cells, white blood cells, plasma, and platelets. Red blood cells deliver oxygen to your body and remove waste. Without them, your body would slowly die. They contain a protein chemical called hemoglobin, which gives it it’s red color. Also, hemoglobin contains Iron, making oxygen molecules attach to it so as the blood passes through tissue...
Leukemia is a form of cancer that starts in the stem cells of the bone marrow that make blood cells. A bone marrow is the material that fills the center of most bones which is where blood cells are made. Leukemia is basically a blood cancer where the cells do not form properly. Leukemia is found in blood cells and since blood cells do not have chromosomes or DNA then they cannot divide or reproduce like somatic cells do. Blood cells form in the bone marrow and when too many blood cells form in the human body then Leukemia cancer is developed. There are three different types of blood cells that increase out of control and are produced in the bone marrow which are White blood cells [leukocytes], Red blood cells [erythrocytes] and Platelets. White blood cells are part of the immune system and help fight off infections. They too aid in the curing of sores, wounds and cuts. Red blood cells hold haemoglobin which carries oxygen and takes out carbon dioxide to and from the cells throughout different organs of the body. Platelets help poke holes in the blood vessels and form clots just as blood vessels are corrupted or damaged (What is Leukemia? par. 4 & 5).
Bacteria exist everywhere in the environment and have continuous access to the body through the mouth, nose and pores of skin. Further more, many cells age and die daily and their remains must be removed, this is where the white blood cell plays its role.
Red blood cells are carriers of oxygen. A percentage of these cells contain hemoglobin, which has the capacity to combine with iron. It's the iron-hemoglobin molecular structure that helps carry oxygen-rich blood from the lungs to your tissues and in return, delivers carbon dioxide back to the lungs to be expelled. A CBC with Differential that shows low red blood cell levels can indicate anemia. RBCs comprise about 40% of total blood volume; the RBC count is the number of red blood cells per cubic millimeter of blood (Rauen, 2012). Normal red blood cells values vary a...
Red Blood Cells contain hemoglobin molecules to help bind to oxygen to bring to other tissues. Without this function, cells would not be able to go through the process of cellular respiration and can only survive a short time. Red Blood Cells are also able to carry bicarbonate as a waste product and carry a variety of hormones to communicate between organs.
Leukemia is a disease in which the bone marrow and other cells are not functioning properly which produce the numbers abnormal cells. Scientist do not know the exact cause of leukemia. Some scientist say that leukemia can be cause by a DNA mutated by some blood cells. There are 4 types of leukemia, leukemia is a cancer that’s start in the blood forming cells of the bone marrow. When one of these cells changes and become a leukemia cell (cancer.org). Red blood cells and white blood cells are completely different. They both are needed for the body to function properly. The red blood carry oxygen while the white blood cells do not (wisgeek.org). If there are too much white blood cells in the body and less red blood cells in the body can led to
In the cardiovascular system, the heart has a big responsibility. The heart is responsible for transporting the nutrients and oxygen to the tissues in the body. The heart is also responsible for transporting waste to its rightful location and carbon dioxide back to the lungs. The heart manages to do this by pumping blood at 40 miles per an hour and beating or pumping 60 to 100 times a minute.
