Phagocytosis of a pathogen during contamination, rapid immune response. Phagocytes are cells of the immune system of the leucocyte category. In particular, monocytes/macrophages, neutrophils, dendritic cells are distinguished. They intervene during a rapid immune reaction. It responds to the invasion of the body by pathogens (bacteria or virus). These immune cells migrate to the site of infection, absorb (phagocyte) pathogens and destroy them. Then they reject the fragments of these agents. This is the first reaction of the immune system during a bacterial or viral invasion. This scientific illustration shows this principle of phagocytosis in four stages: adhesion, internalization, digestion, rejection.

Illustration of the signs of ageing in skin, dulling of the epidermis, brown spots, skin slackening and wrinkles. In the centre of the image: a cross-section illustration of young skin enabling a comparison with different types of ageing: -Top left illustrates the dulling of the epidermis, the skin is dry and cutaneous microrelief is irregular, causing the skin to become permeable to pollutants and dehydration. Superficial microcirculation is less good; skin cells become less oxygenated. -Top right illustrates spots. If they are brown it is due to melanin deposits, when red it is due to superficial microcirculation vessels, which are dilated. -Bottom left illustrates the loss of firmness due to diminished activity of the fibroblasts (blue). Fibroblasts are responsible for skin's elasticity, producing elastin and collagen -Bottom right illustrates wrinkles due to the deterioration of collagen (white vertical) and elastin (pink horizontal) fibers.

Adult trachea, horizontal section healthy and crowded trachea. Simplified horizontal section through the trachea of an adult. This illustration compares the diameter of the tracheal lumen on a healthy trachea and on a congested or edematous trachea. To the left of the drawing, the tracheal lumen of a healthy adult trachea measures approximately 25 mm. The cartilaginous part of the trachea is shown in purple. The pink part represents the mucous membrane. We can clearly see on the right section of an edematous trachea that the tracheal lumen is narrowed. Nevertheless, it remains open enough to let air through. In the event of inflammation, the respiratory resistance is increased in a more moderate way compared to that of a child.

Illustration of lipids : triglyceride, LDL and HDL. Triglycerides are lipid molecules which form in the small intestine from the fat we eat. They are also produced in the liver from the sugar excess in our food. They need lipoproteins to be carried through the body. LDLs (low density lipoproteins) are responsible for carrying cholesterol in the blood to the bodys cells. LDLs are produced by the liver from very low density lipoproteins (VLDL). LDLs are responsible for the formation of atheromatous plaques and are called bad cholesterol (LDL related cholesterol). HDLs (high density lipoproteins), are responsible for carrying excess cholesterol to the liver where it can be eliminated. This allows an accumulation of cholesterol in the blood vessels to be avoided thus avoiding the risk of atheroma. HDLs are qualified as good cholesterol (HDL related cholesterol).
