Red blood cell From Wikipedia‚ the free encyclopedia [pic] Human red blood cells (6-8μm) 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. These cells’ cytoplasm is rich in hemoglobin‚ an iron-containing biomolecule that

the brain denied blood and oxygen that is required and damage is done to a part of the cells. The effect of the patient depends upon where the damage occurs and the severity of the stroke. Each year alone about 150‚000 people in America die from a stroke or are seriously disabled. Stroke is among the top five causes of death. It generally happens very suddenly and it can take up to five to seven days to completely effect the patient. Depending on how many of the brain cells die during the stroke

Question: Describe the path taken by a red blood cell as it passes from the left atrium to the cells in the cell kidneys and back to the left atrium Answer: The red blood cells enter through the right atrium and there the blood color is blue. Next‚ it goes through the right ventricles‚ and then to the pulmonary artery. After goes through those valves‚ it then goes through the lungs‚ and the lungs turn the blood into red‚ thus stating that it contains oxygen. Pass the lungs‚ and then into the pulmonary

Hi! My name is Rafael‚ the Red Blood Cell‚ doctors call me erythrocyte and born in the bone marrow. My shape is bi-concave disk. Also do not possess a nucleus. I am one of trillions of red blood cells that live inside and travel through your body. I deliver oxygen to all the organs and tissues and transport wastes as carbon dioxide out of your body. Oxygen helps keep the body running and healthy. I tend to jump aboard the train inside the heart. The trip around the body only takes 45 seconds

SYNTHETIC BLOOD This is an artificial blood made up of synthetic blood products. 1. The two main types of non-cellular blood products are hemoglobin based and Perfluorocarbon (PFC) based. a. Hemoglobin The hemoglobin-based substitutes use hemoglobin from several different sources: human‚ animal‚ and recombinant. Human hemoglobin is obtained from donated blood that has reached its expiration date and from the small amount of red cells collected as a by-product during plasma donation.

Task 1a: Erythrocytes: These are also known as red blood cells and contain haemoglobin with their primary function being to carry oxygen from the lungs then disperse it into the tissues throughout the body through a series of capillaries. The distinctive red colour of the erythrocytes or red blood cells is due to their contents of haemoglobin. In order to facilitate its purpose the erythrocytes can be described as biconcave in shape therefore enabling them to diffuse oxygen around the body with

My Journey Through the Human Body My name is Ruby; I am a red blood cell. I am a dazzling ruby red color (hence my name) with a small area of inner pallor and I am very small: only about 6 µm in diameter. I get my red color from a protein chemical called hemoglobin‚ which is bright red. Hemoglobin not only gives me my beautiful color‚ it also contains the element iron‚ which makes it a good vehicle for transporting oxygen and carbon dioxide. I have a very important role in the circulatory system

In solution hypotonic to the sheep’s red blood cells‚ the red blood cells will lyse‚ as a result of the water entering the cell via osmosis. First‚ a stock solution of NaCl was prepared at concentration 1.0M. Working solutions were made ranging from hypotonic to hypertonic with a negative control at isotonic solution (150mM). The solutions were diluted up to 4 mL into 5 test tubes‚ (0mM‚ 0.13mM‚ 0.15mM‚ 0.17mM‚ 0.3mM 0.5mM) using distilled water to dilute the stock solution. The working solutions
