Cardiac and skeletal myocytes are occasionally known as muscle fibers because of their lengthy and fibrous form. White blood cells provide the basis for the innate immune system as well as interacting with specific immune processes. Figure 1. One specific function is the ability of a neutrophil white blood cell to form neutrophil extracellular traps (NETs). This iron-containing molecule binds oxygen as oxygen molecules enter blood vessels in the lungs. The blood and other tissues contain high numbers of neutrophils and these relocate to areas of infection. Monocytes patrol the body looking for damaged cells and pathogens. High white blood cell count causes include the presence of infection, tissue necrosis, tissue inflammation (acute or chronic), stress, immune system disorders, lifestyle factors such as smoking and being sedentary, and cancer. The common lymphoid progenitor produces either natural killer cells (granular lymphocytes) or small lymphocytes. Leukocytes migrate to areas of infection and injury when circulating antigen-presenting cells (APCs) some types of white blood cells recognize abnormal surface membrane molecular patterns. The common myeloid progenitor is responsible for the production of all other blood cell types erythrocytes, thrombocytes, and myeloid leukocytes. When released, their granules act as lysosomes to digest cellular macromolecules, destroying the neutrophil in the process. Arterioles direct blood flow to the capillaries surrounding lung alveoli. When white blood cells detect pathogens in your body, they quickly attack them so that you can stay healthy and safe. They carry out their functions of engulfing dead cells, cellular debris, and bacteria only after migrating into body tissues. These can self-renew.
