neutrophil?
Macrophages are white blood cells that locate and phagocytize (eat) bacteria, viruses and dead or injured body cells. They also play a role in alerting the rest of the immune system to the presence of invaders. Macrophages arise from monocytes which are a type of white blood cells. When the monocytes leave the blood they become macrophages.
Macrophages
Neutrophils are the most active phagocytic cells found in circulating blood. They are the first responders to sites of infection or inflammation, where they engulf and destroy pathogens. Monocytes also play a role in phagocytosis but typically differentiate into macrophages once they leave the bloodstream and enter tissues.
monocytes ( a type of defensive white blood cell or leucocyte) are immature when they leave the blood vessels but mature and develop rapidly into active cells called macrophages.
Nutrients leave the gut and enter the bloodstream through the lining of the small intestine.

Oxygen leaves the blood through the process of diffusion across the alveoli in the lungs into the bloodstream. This occurs due to differences in oxygen concentration between the air in the alveoli and the blood in the capillaries surrounding them.
Most chemical drugs are out of your bloodstream and urine in 3-4 days.

In the lungs. This process is called the Gas Exchange.Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
