macrophage are immune system cells that patrol the blood and body tissues. when a macrophage finds a foreign invader, the macrophage ingests (takes in) the foreign invader and then chemically digests (breaks down) that foreign invader. to perform this frequent chemical digestion, macrophage have more than the average body cell is

Macrophages are immune system cells that are vital to the development of non-specific defense mechanisms that provide the first line of defense against pathogens. These large immune cells are present in nearly all tissues and actively remove dead and damaged cells, bacteria, cancerous cells, and cellular debris from the body.

What is Macrophages?

Macrophages are specialized cells that hunt for, engulf, and kill bacteria and other dangerous organisms. They can also activate other cells by releasing substances known as cytokines, which present antigens to T cells and start an inflammatory response.

Blood monocytes that leave the bloodstream to differentiate in various organs give rise to macrophages. Each macrophage population exhibits significant variety, which most likely reflects the level of specialization necessary for each tissue's environment.

Identify the bone that articulates with the distal end of the femur. view available hint(s) identify the bone that articulates w
MatroZZZ [7]

The correct answer is: <em>tibia</em>

The femur, also known as the thigh bone, is one of the longest bones of the human body. The distal point of the femur refers to the area furthest away from its point of attachment, which in this case is the hip joint (please refer to the attached image). When referring to the image, you can see that the distal end of the femur articulates with the bone known as the tibia or shin bone. The tibia is the larger of the two bones located at the distal end of the femur. The tibia includes the knee and ankle joints. Therefore, the bone that articulates with the distal end of the femur is the tibia.
