White blood cell

Components & Function of Blood. The four major Blood Components are •Plasma •red cells •white cells •platelet •Plasma is the liquid part of the blood that is made up of 55% fluid, this is the blood’s liquid medium, by itself is straw-yellow in colour. The total volume of blood plasma is about 2.7-3.0 litres in human. The plasma carries carbon dioxide , hormones and waste. •Red blood cells •The red blood cells are called erythrocytes, the red blood cells contain hemoglobin which…

system works to protect the body to stop it getting an infection or a virus it does this with the help of cells such as lymphocytes which travels in between the nodes through channels called lymphatic, which meet ducts that empty into blood vessels this is how the lymphocytes enter the blood. There are 3 types of lymphocytes; B-lymphocytes (B-cells), T-lymphocytes (T-cells), Natural killer (NK) cells each of these react differently to kill and remove microbes. The lymphatic system is responsible…

Hippocrates is considered the father of medicine, and it turns out the guy was right about a lot of things. For instance, he is known for having claimed that “All disease begins in the gut.” These words were spoken 2,500 years ago, and today’s scientists are just beginning to understand how right he was. As it turns out, poor gut health can absolutely hinder thyroid function and trigger autoimmune diseases such as Hashimoto’s disease. Leaky Gut and Autoimmune Response The human GI tract…

reported high incidence of depression and loss of trust in their treatment team (Weigle, 2013). Psoriasis can be difficult to treat because the causative factor for the skin lesions is a malfunctional immune response. Many medications that target T cells in the body affect the entire immune system and have dangerous side effects. This is why it is especially important for the psoriasis patients to have individualized treatment that addresses nondermatological manifestations as well as the…

cases of HAT are due to Trypanosoma brucei gambiense. (1) The tsetse fly acts as the vector for the transmission of this protozoan parasite between mammalian hosts. Both the male and female flies are able to transmit the parasite since they are both blood-feeders. However, a fly needs to first feed on an infected mammalian host in order to become infected with trypanosomes. (1) Trypanosomes are protozoa (unicellular…

For over 55 years, humans have been flying in space. With an understanding of evolution, it has always been assumed that human bodies have adapted to the gravitational force found here on Earth. The space station and the shuttle that most NASA astronauts will stay in orbits 350 km above Earth, with a gravitational pull 90% stronger than it is on the ground (NASA Space Bones). Giancoli describes objects orbiting the Earth as feeling weightless because they are, in essence, free falling towards…

or DAT. This test is used for the detection of IgG or C3 antibodies which are attached to the RBC’s surface. These antibodies are important to be detected because they might sometimes cause anemia due to destruction of RBCs. DAT is mainly done on blood samples of newborns, especially when a newborn is suffering from jaundice. • Procedure: 1. Place the sample of RBCs to be tested in a 5 % suspension of isotonic saline. 2. Using a clean pipette, add 1 drop of the RBCs suspension prepared…

situations, prolonged activation of immune cells can lead to tissue destruction, fibrosis, and uncontrolled angiogenesis. Despite the eyes are immune-privileged sites, deposition of inflammatory proteins in the drusen and observation of multiple types of immune cells in AMD eyes[9] indicate that this privilege is likely revoked. The immune-privileged of retina is achieved by formation of vascular barrier and secretion of immunosuppressive molecules[10]. RPE cells can modulate retinal immune…

made of dead skin cells, natural oils (sebum) and sweat that your pores secretes. Although we agree that this sounds like the things you should be washing off your skin, but this delicate combination helps your skin maintain the correct pH5.5 balance.…

When injury occurs, the first step your body does to stop the blood flow involves the first step of wound healing, homeostasis (Valls,…
