Carbon monoxide is a toxic gas for the heart and arteries. Affinity between carbon monoxide and hemoglobin is 200 times stronger than between oxygen and hemoglobin. This lessens the blood's capacity to transport oxygen.

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 skins elasticity, producing elastin and collagen -Bottom right illustrates wrinkles due to the deterioration of collagen (white vertical) and elastin (pink horizontal) fibers.

Top left, a healthy bronchiole, bottom, two asthmatic bronchioles. An allergen (green star) triggers an asthma attack by the activation of lymphocytes producing IgE (green Y) leading to the degranulation of mast cells (purple) which release leukotrienes (black beads) and cytokines (blue beads) mediators of inflammation of the mucosa which leads to bronchoconstriction of smooth muscle fibers, hypersecretion of mucus and obstruction of the airways.

Epithelia continually renews itself due to differentiating stem cells. Here, culture of bronchial stem cells destined for transplant and multiplication in the pulmonary alveoli. For the following reasons, adult stem cells may eventually prove to be better for cell therapy than embryonic stem cells: their greater availability in adult tissue, the absence of immune-response rejection, their decreased disposition for tumors. Removed from the patient, stem cells can be cultured and multiplied to attain a quantity that is sufficient to treat sickness or injuries.

This illustration explains the process of metastasis. Once metastatic cells are attached to the basement membrane (a physical barrier that seperates tissue components), they break through with the help of an enzyme called type IV collagenase. Cancer cells then move through the blood stream enabling them to spread to other parts of the body. A secondary tumor may form at another site in the body. Illustration by Jane Hurd.
