Can low hemoglobin affects periods?
Low hemoglobin can affect your period in various ways. It can cause more cramping, more hormone changes which can lead to you being more moody, and it can even give you an irregular menstrual flow. To higher your hemoglobin levels eating eggs is recommended. Eggs have Omega 3 fatty acids which is great for your hemoglobin. good luck.
Why would a baby be born with high white blood count?
There are a great number of reasons that a baby might be born with high white blood count. One reason is that they may have an infection.
Which hormone regulates rate of red blood cell production?
Red blood cells contain hemoglobin which is is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates. The red blood cells also have enzymes that help the cell produce energy. There are many other proteins too.
What gives red blood cells their color and carries oxygen?
Short answer: Blood is red because of hemoglobin, an iron containing material that is able to both absorb and release oxygen and is one of the most essential parts of blood. When it has absorbed oxygen it is bright red in color and when it releases oxygen it is dull red.Long answer:Our blood contains many different materials and cells, each with a different purpose. Plasma, the liquid portion of the blood, comprises more than half of the blood. Plasma is light yellow in color, and is thicker than water, because it contains many substances, in addition to the actual blood cells. These substances include proteins, antibodies, fibrinogen, which helps blood clot, carbohydrates, fats, salts, etc., and when it is returning to the heart from the cells, dissolved carbon dioxide.Red blood cells (also called corpuscles) color the blood. Since there are actually trillions of them circulating in one's body at any one time, their great amount is what gives blood the red color.As a red blood cell matures, and takes on an adult form in the marrow of the bone, it loses its nucleus and increases its production of hemoglobin. Hemoglobin is the red pigment, or color of blood, and contains iron, combined with protein.When blood passes through the lungs, oxygen joins the hemoglobin of the red cells. From there, the red cells carry the oxygen through the arteries and the capillaries to all other cells of the body.Red blood cells stick around for about four months before they are broken up (mostly in the spleen) and then replaced by new red blood cells.On the contrary, horseshoe crabs have blue blood, which, rather than using hemoglobin, uses a copper containing compound to serve the same purpose.
How is oxygen transported in the blood?
Hemoglobin is the compound in red blood cells that carries oxygen from the lungs to body cells. The oxygen combines readily with the ion in hemoglobin, and hemoglobin can carry more than twenty times its own volume in oxygen. After releasing oxygen to the cells, hemoglobin collects carbon dioxide and carries it to the lungs where it is exhaled.
What does elevated hemoglobin means?
Hemoglobin is a protein-based component of red blood cells which primary role is transferring oxygen from the lungs to the rest of the body. Although not many people know about this, hemoglobin is actually the reason red blood cells appear red, although oxygen-rich blood is noticeably brighter than the depleted blood returning to the heart and lungs. Fresh hemoglobin is produced in the bone marrow as needed. Structure of hemoglobin The hemoglobin molecule is a group of four globular protein subunits and each of these subunits is composed of a protein chain tightly associated with a non-protein heme group. It is proven that each individual protein chain arranges in a set of alpha-helix structural segments connected together in a specific arrangement called myoglobin fold. This folding pattern contains a pocket which is perfectly suitable to strongly bind the heme group. What exactly is this heme group? A heme group consists of an iron atom (Fe) held in a heterocyclic ring, known as a porphyrin. This iron atom is the exact site of oxygen binding. The fact is that an iron atom is bonded four nitrogens in the center of the ring and two additional bonds perpendicular to the plane on each side can be formed with the iron to form the fifth and sixth positions, one connected strongly to the protein, the other available for binding of oxygen. Types of hemoglobins in humans In the embryo: Gower 1 (ξ2ε2) Gower 2 (α2ε2) (PDB 1A9W) Hemoglobin Portland (ξ2γ2) In the fetus: Hemoglobin F (α2γ2) (PDB 1FDH) - Hemoglobin F is the predominant hemoglobin during fetal development In adults: Hemoglobin A (α2β2) (PDB 1BZ0) - This is the designation for the normal hemoglobin that exists after birth. Hemoglobin A2 (α2δ2) - This is a minor component of the hemoglobin found in red cells after birth Hemoglobin F (α2γ2) The creation of hemoglobin Like all proteins, the exact copy or blueprint for hemoglobin exists in DNA and normally, every individual has four genes that code for the alpha protein, or alpha chain.Two other genes code for the beta chain. The alpha chain and the beta chain are made in precisely equal amounts, despite the differing number of genes. The protein chains join in developing red blood cells, and remain together for the life of the red cell. The fact is that essentially, hemoglobin develops a hunger for oxygen molecules. Heme synthesis Heme is synthesized in a complex series of steps involving enzymes in the mitochondrion and in the cytosol- two organelles of the cell. First one molecule called 5-aminolevulic acid (ALA) is being transported to the cytosol where a series of reactions produce a ring structure called coproporphyrinogen III which then returns to the mitochondrion where an addition reaction produces protoporhyrin IX. The enzyme ferrochelatase inserts iron into the ring structure of protoporphyrin IX to produce heme. Globin synthesis The fact is that two globin chains combine to form hemoglobin. One of the chains is designated alpha and the second chain is called "non-alpha". This is because there is a number of variables influence the nature of the non-alpha chain in the hemoglobin molecule. For example: The fetus has a distinct non-alpha chain called gamma. After birth, a different non-alpha globin chain, called beta, pairs with the alpha chain. The combination of two alpha chains and two non-alpha chains produces a complete hemoglobin molecule Physiology of blood and hemoglobin circulation Whenever the blood is carried into the lungs, these hemoglobin proteins attract whatever oxygen is available and this oxygenated blood then travels throughout the entire bloodstream, releasing oxygen into the various muscles and organs all around the body. When these red blood cells are being spent, they are being transferred to the gastrointestinal system for disposal and new red blood cells with hemoglobin take their place in the bloodstream. How is hemoglobin measured? There are several methods exist for measuring hemoglobin and most of them are done currently by machines designed to perform several different tests on blood. In this machine, the red blood cells are broken down to get the hemoglobin into a solution. The free hemoglobin is exposed to some specific chemicals that are containing cyanide which binds tightly with the hemoglobin molecule to form cyanmethemoglobin. By shining a light through the solution and measuring how much light is absorbed, the amount of hemoglobin can be determined. Normal values of hemoglobin The hemoglobin level is expressed as the amount of hemoglobin in grams per deciliter of blood and the normal ranges for hemoglobin depend on the age and, beginning in adolescence, the sex of the person. The normal ranges are: Newborns: 17-22 gm/dl One (1) week of age: 15-20 gm/dl One (1) month of age: 11-15gm/dl Children: 11-13 gm/dl Adult males: 14-18 gm/dl Adult women: 12-16 gm/dl Men after middle age: 12.4-14.9 gm/dl Women after middle age: 11.7-13.8 gm/dl How the test is performed? Hemoglobin levels are amongst the most commonly performed blood tests, usually as part of a full blood count or complete blood count. The test is rather simple. Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand and the puncture site is cleaned with antiseptic. A small needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation and once the blood has been collected, the needle is removed. Test results Lower-than-normal hemoglobin may indicate: anemia (various types) erythropoietin deficiency (from kidney disease) red blood cell destruction associated with transfusion reaction bleeding lead poisoning malnutrition nutritional deficiencies of iron, folate, vitamin B-12, vitamin B-6 over hydration Higher-than-normal hemoglobin may indicate: congenital heart disease cor pulmonale pulmonary fibrosis polycythemia vera increased RBC formation associated with excess erythropoietin What does a low hemoglobin level mean? Low hemoglobin is referred to the condition called anemia. There are many reasons for anemia. Some of the more common reasons are: loss of blood (traumatic injury, surgery, bleeding colon cancer), nutritional deficiency (iron, vitamin B12, folate), bone marrow problems (replacement of bone marrow by cancer, suppression by chemotherapy drugs, kidney failure), and abnormal hemoglobin (sickle cell anemia) Possible causes of elevated hemoglobin A high hemoglobin count usually suggests that you have too many red blood cells. This condition is also called erythrocytosis. It can lead to a several complications because it can impair circulation and lead to abnormal clotting. An elevated hemoglobin concentration is usually the result of 2 mechanisms: increased red blood cell production as a compensatory mechanism when blood oxygen carrying capacity is compromised to meet the demand of tissue contracted plasma volume resulting in an appearance of greater red cell volume Causes of an elevated hemoglobin count may include: Living at high altitudes- Because the higher the altitude is, the lower oxygen level is in the air- body is producing more hemoglobin to bind as much oxygen as it is possible! Smoking- Several studies done in the past with smokers volunteers have proven that great percentage of the smokers have the elevated hemoglobin level, although the mechanism is still unknown. Some experts believe that it could be because of low level of "pure" oxygen in the smoker's lungs! So, this could be an adoptive mechanism on low oxygen levels! Dehydration - Dehydration produces falsely high hemoglobin which disappears when proper fluid balance is restored. The symptoms and possible complications Although much of the clinical focus has been on anemia as a condition where there is lack of hemoglobin, there are also problems at the high end. The most notable consequence is increased blood viscosity. Several studies have proven that the relation between hemoglobin and blood viscosity is linear when the hematocrit is <0.50 (equivalent to a hemoglobin value of 160 g/L). Above this hemoglobin concentration, the relation becomes exponential, which means that a small increase in hemoglobin or hematocrit results in a large increase in viscosity. Once hemoglobin concentrations reach 180 g/L, the blood viscosity reaches a level that impairs microcirculation and an inadequate amount of oxygen is transported to tissues, similar to the situation with severe anemia. Symptoms Peripheral cyanosis and impaired mental function resulting from compromised cerebral blood circulation are the two most common symptoms of elevated hemoglobin! Additionally, because of the poor blood flow, the risk of thrombo-embolism increases significantly. Treatment Because the high hemoglobin couldn't be considered as a special disorder it could be only treated as a symptom of some other underlying disease. That's why- treating the underlying disease will probably lower the hemoglobin level!

What carries blood and gives blood its color?
Proteins don't give blood its color, the great amount of red blood cells do. Hence the name, they are red and give blood its color.
How does poisonous carbon monoxide affect blood?
Carbon monoxide, which has a higher affinity for hemoglobin in the red blood cell, displaces oxygen from the hemoglobin molecule, thus decreasing the oxygen level in the bloodstream, and reducing its delivery to the bodily tissues and cells.
