Rheumatoid arthritis is a chronic inflammatory disease that attacks joints and surrounding tissues. It is characterized by periods of remission and flare-ups. Rheumatoid arthritis is an autoimmune condition where the immune system mistakenly attacks the body's own tissues, causing inflammation,pain, and potential joint damage. This disease commonly affects joints in the hands, wrists, and knees, leading to swelling and deformity over time.

When a patient is bleeding heavily from a wound, the immediate priority is to control the bleeding. The best initial action is to apply direct pressure to the wound using a clean cloth or bandage. This helps to stem the flow of blood and allows time for clotting to begin. Elevating the limb can also help reduce blood flow to the area, but applying direct pressure is the primary and most effective method. Tourniquets are used only as a last resort when direct pressure and elevation do not control the bleeding.

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell. It is essential for growth, development, and tissue repair in multicellular organisms. Mitosis consists of several stages: prophase, metaphase, anaphase, and telophase, followed by cytokinesis, which divides the cytoplasm and organelles into two daughter cells. Unlike meiosis, which produces four genetically diverse gametes (sperm or egg cells), mitosis ensures that each daughter cell receives an identical set of chromosomes.
