11 Blood Composition Blood is a bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. When it reaches the lungs, gas exchange occurs when carbon dioxide is diffused out of the blood into the pulmonary alveoli and oxygen is diffused into the blood. This oxygenated blood is pumped to the left hand side of the heart in the pulmonary vein and enters the left atrium. From here it passes through the mitral valve, through the ventricle and takes all around the body by the aorta. Blood contains antibodies, nutrients, oxygen and much more to help the body work. In vertebrates, it is composed of blood cells suspended in blood
The heart is a major organ in the body, this organ pumps blood around the body, through veins, capillaries and arteries. The blood carries oxygen to our cells and also carries waste products which include water and carbon dioxide, which are products of respiration. Blood also helps spread out salts, enzymes, urea, nutrients, hormones and heat across the body.
The blood circulates around the body. The heart contract and relax, this mechanism of heart makes the blood to flow in the arteries to the body from heart and come back from body to heart through veins. The arteries carry oxygenated blood or oxygen rich blood and the veins carry deoxygenated blood or oxygen poor blood. This flow creates the pressure on the arterial wall and the pressure that is exerted on the arterial wall is known as blood pressure. Blood pressure is expressed by the
Red and white blood cells are the two types of blood cells in the human body. Red blood cells transport oxygen around the body which is transferred through the bloodstream. It moves oxygen into the body and then removes it. They are absorbed through its haemoglobin.
29. If all the 280 million molecules of hemoglobin contained in RBCs were free in the plasma,
The blood contains the oxygen, platelets, nutrients, red and white blood cells, hormones which are all important materials for metabolism.
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 is a bodily fluid that transports oxygen and nutrients to the cells within the body. Blood has plasma that lets the different types of blood travel round the body. Plasma contains proteins that have different functions for the blood- clotting, transporting and defence organisms and osmotic organisations. The plasma carries the red blood cell which has a elastic membrane so it can fit through the small capillaries within the body. Red blood cells can be also known as erythrocytes they don’t have a nucleus when they are matured which gives a bigger space for oxygen, although as there is no nuclei the red blood cells can’t divide so they only live for around 120 days. Red blood cells gain their colour from haemoglobin, oxygenated blood which is known as arterial blood which flows through the arteries coming from the heart and
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,
a circulatory system which facilitates the exchange of materials for all but the simplest animals
The right atrium is where the process begins. Then, blood travels through the tricuspid valve to the right ventricle, and from there to the pulmonary artery. Once the blood travels through the pulmonary artery, it reaches the lungs. While in the lungs, the blood goes through a gas exchange: deoxygenated blood gets oxygenated (The gas exchange takes place in the alveoli, which are tiny air sacs in the bottom of the lungs
This article indicates how epideictic rhetoric and demonstration may be correlative in a general-interest newspaper framed as onefold address produced by a corporate author. The validity of the approach is dual. In the terms of trope, to detect the flexibility epidemic rhetoric to journalistic discourse; and in the field of journalism studies, the target is to absorb the theory of epideictic rhetoric so that improve the conceptualized of the property of controversy in the newspaper. At the stage of genre, invention and reality find their respective equivalents in the story and the newspaper. Fiction as genre meets its
Chaucer’s “The Wife of Bath’s Prologue and Tale” in The Canterbury Tales appears to be an illustration of feminism, one that showcases a female character’s progression in power in a primarily patriarchal society. However, beneath the simplistic plot of women’s empowerment, lies underlying themes of antifeminism in the character, Alison of Bath. Alison endorses the misogynistic role which she is fighting against with the objectification of her own body, her misinterpreted dictations of religion, and her fascination of sovereignty and dominance. Although Alison sees herself as a feminist, it is unlikely that men in the middle ages saw her the same way. She embodies the stereotypes of women in medieval literature; lustful, irrational, domineering, and a danger to a man’s salvation. Throughout the prologue and the tale, there are inconsistencies with what Alison preaches and how she behaves. That leads to the question, is Chaucer the forward-minded feminist he is often depicted as, or is Alison of Bath a mockery of the ideals of feminism and an illustration of what men thought of women at the time?
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.
Did you know the circulatory system comprises the heart, veins, capillaries and arteries? The system moves pure oxygenated blood in a continuous and controlled way from the lungs and heart so that blood can reaches every cell. Blood travels through a type of network of vessels that include capillaries that permeate every tissue of the body. Once it’s depleted of oxygen, the blood returns to the lungs and heart and the cycle continues.
veins to the tissues of the body. These walls do not let out blood but
