Introduction The erythrocytes (red blood cells) are flat, nucleusless discs with a size of about 8 micrometers and are the main representatives in the blood of vertebrates. Their biconcave shape (wider at the edges than in the center) and size allow optimal flow properties in narrow capillaries. Inside the dented center is the red blood … Erythrocytes
Carotenoids are found in various fruits and vegetables and have many health-promoting properties. Probably the best known carotenoid is beta-carotene. What are carotenoids? Carotenoids are secondary plant compounds. Since the body cannot produce them itself, they must be supplied through the daily diet. Scientists have identified about 600 carotenoids to date. The health-promoting substances are … Carotenoids: Function & Diseases
Acute disseminated encephalomyelitis (ADEM) is a disease of the central nervous system (CNS). It is also known as perivenous encephalomyelitis or Hurst encephalitis and predominantly affects children. What is acute disseminated encephalomyelitis? Acute disseminated encephalomyelitis (ADEM) is a disease of the central nervous system (CNS). ADEM belongs to the group of acquired demyelinating diseases of … Acute Disseminated Encephalomyelitis: Causes, Symptoms & Treatment
Urine time volume (also urinary time volume) includes the amount of urine that is excreted in a specified period of time. In all cases, this time period is 24 hours. The measured volume of urine is used primarily to assess kidney disease. Normally, about 1.5 to two liters of urine are passed daily. The paired … Urine Time Volume: Function, Tasks, Role & Diseases
Alpha-1-fetoprotein (AFP) is formed mainly in embryonic tissues, where it serves as a transport protein. After birth, very little AFP is formed. Elevated serum or blood levels in children and adults indicate tumors, among other things. What is alpha-1 fetoprotein? Alpha-1 fetoprotein is a protein that is produced in the entodermal tissue during embryogenesis. The … Alpha-1 Fetoprotein: Function & Diseases
The ultralong feedback mechanism is a feedback process in the human body that is particularly important for hormone balance. One such self-regulating feedback loop is, for example, the interplay between the thyroid hormone and the thyrotropin (TSH) it releases. If this feedback loop is disturbed, it results in diseases such as Graves’ disease, an autoimmune … Ultralong Feedback Mechanism: Function, Tasks, Role & Diseases
If toxins enter the human organism through diet or other environmental influences and cannot be eliminated, inflammation occurs. The inflammatory process can be stopped by regenerating the intestinal mucosa, because if the intestinal mucosa no longer releases the inflammatory substances into the body, the inflammatory metabolism is stopped. What is inflammatory metabolism? Toxic substances are … Inflammation Metabolism: Function, Role & Diseases
Albumins are blood proteins that belong to the globular protein group. Their most important function in the human body is to maintain colloid osmotic pressure. What is albumin? Albumins are proteins that belong to the plasma protein group. Human albumins are also known as human albumin. The blood proteins have a molecular mass of approximately … Albumin: Function & Diseases
During filtration, low-molecular-weight blood components are sorted out in the kidney. This produces the so-called primary urine, part of which is later excreted. In this process, the first stage of filtration takes place in the renal corpuscles. There, after special cross-flow filtration, the smaller parts of the blood plasma remain in an ultrafiltrate. In addition … Filtration: Function, Tasks, Role & Diseases
Even though blood plasma is needed everywhere and donors of plasma are basically wanted, there are still some selection criteria with regard to donors. This is because only healthy people who meet certain criteria are allowed to donate blood plasma. Who qualifies as a donor and what should you look out for? You can find … Plasma Donation: Suitable Donors
Lactic acid is one of the hydroxycarboxylic acids. It forms an important product of metabolism. What is lactic acid? Lactic acid (Acidum lacticum) is an organic acid. It belongs to the hydroxycarboxylic acids and is thus an alkanoic acid. It has both a hydroxy group and a carboxy group. Lactic acid is also known as … Lactic Acid: Function & Diseases
Lopinavir is a drug used in the therapy of HIV infection, acting as a protease inhibitor. The HIV protease inhibitor is used in combination with AbbVie’s product ritonavir and is known on the market by the trade name Kaletra. The drug received approval from the relevant EU Commission in 2001. What is lopinavir? Lopinavir is … Lopinavir: Effects, Uses & Risks
