Recent research has helped to solidify the link between the proper function of the vertebral arteries and vertigo. The researchers specifically focused on a rare condition called loop formation. It is a disorder where small loops form in the vertebral arteries, thereby restricting blood flow. When a cross-section of vertigo patients was studied, this condition seemed to be more common. What else can cause kinks in the vertebral arteries leading to reduced blood flow? Does understanding of the conditions that bring vertigo provide information into a natural way to find relief? Read on to learn more. What Can Reduce Vertebral Blood Flow and Lead to Vertigo? The upper cervical vertebrae play a major role in facilitating blood flow to the brain. Misalignment of the C1 and C2 vertebrae can result in reduced blood flow. Vertigo is not the only possible condition that may result from this scenario. Migraines are also common when these circumstances exist. This explains why it is s...

                                What Is Ovulation? Ovulation is the release of an egg from one of a woman's ovaries. After the egg is released, it travels down the fallopian tube, where fertilization by a sperm cell may occur.  Ovulation is the release of an egg from one of a woman's ovaries. After the egg is released, it travels down the fallopian tube, where fertilization by a sperm cell may occur.  Ovulation typically lasts one day and occurs in the middle of a woman's menstrual cycle, about two weeks before she expects to get her period. But the timing of the process varies for each woman, and it may even vary from month to month.  If a woman is hoping to become pregnant, she will want to keep track of when she may be ovulating. Knowing when a woman is ovulating each month is helpful because she is the most fertile — or able to become pregnant —around the time of ovulation....

                                Irregular Periods The normal length of a woman’s menstrual cycle is 28 days, but this varies between individuals. Irregular menstruation is when the length of the cycle is more than 35 days, or if the duration varies. A period, or menstruation, is the part of the menstrual cycle in which the endometrium, which is the lining of the uterus, is shed. This appears as bleeding from the womb that is released through the vagina. Periods usually start during puberty, between the ages of 10 and 16 years, and they continue until menopause, when a woman is 45- to 55-years old. Irregular periods, also called oligomenorrhea, can occur if there is a change in  contraception method, a hormone imbalance, hormonal changes around the time of the menopause, and endurance exercises. Treatment for irregular periods during puberty and around the menopause is not usually necessary, ...

                               Leukocytes              White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. Leukocytes are found throughout the body, including the blood and lymphatic system. Details System Immune system Identifiers Acronym(s) WBC MeSH D007962 TH H2.00.04.1.02001 FMA 62852        All white blood cells have nuclei, which distinguishes them from the other blood cells, the anucleated red blood cells (RBCs) and platelets. The different white blood cell types are classified in standard ways; two pairs of broadest categories classify them either by structure (granulocytes...

                             ERYTHROCYTES       Red blood cells (RBCs), also referred to as red cells red blood corpuscles, haematids, erythroid cells or erythrocytes (from Greek erythros for "red" and kytos for "hollow vessel", with -cyte translated as "cell" in modern usage), are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O2) to the body tissues—via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or gills of fish, and release it into tissues while squeezing through the body's capillaries. Details Function Oxygen  transport Identifiers Acronym(s) RBC MeSH D004912 TH H2.00.04.1.01001 FMA 62845    The cytoplasm of erythrocytes is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells and the blood. Each human re...

     Cholesterol in blood.               Cholesterol is a waxy substance found in your blood. Your body needs cholesterol to build healthy cells, but high levels of cholesterol can increase your risk of heart disease. With high cholesterol, you can develop fatty deposits in your blood vessels. Cholesterol is a fat-like, waxy substance that helps your body make cell membranes, many hormones, and vitamin D. The cholesterol in your blood comes from two sources: the foods you eat and your liver. Your liver makes all the cholesterol your body needs. Cholesterol and other fats are carried in your bloodstream as spherical particles called lipoproteins. The two most commonly known lipoproteins are low-density lipoproteins (LDL) and high-density lipoproteins (HDL). What is LDL (low-density lipoprotein) cholesterol? What is HDL (high-density lipoprotein) cholesterol? LDL (“bad") cholesterol can contribute to the formation of plaque bui...

                               HUMAN BLOOD            Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.           Human body has about 5.6 liters (6 quarts) of  blood . This 5.6 liters of  blood circulates  through the body three times every minute. In one  day , the  blood  travels a total of 19,000 km (12,000 miles)—that's four times the distance across the US from coast to coast. Comment down what you want to read next.
