  • Malaria: Mosquito Host

    Malaria: Mosquito Host

    Animations

    (3 min 59 sec) A mosquito becomes infected with malaria when it sucks the blood from an infected human. Once inside the mosquito, the parasites reproduce in the gut and accumulate in the salivary glands, ready to infect another human host with the next bite.

  • Malaria: Human Host

    Malaria: Human Host

    Animations

    (4 min 18 sec) When a malaria-carrying mosquito bites a human host, the malaria parasite enters the bloodstream, multiplies in the liver cells, and is then released back into the bloodstream, where it infects and destroys red blood cells.

  • Cloning an Army of T Cells for Immune Defense

    Cloning an Army of T Cells for Immune Defense

    Animations

    (4 min 21 sec) View the animation to see how one type of immune cell—the helper T cell—interprets a message presented at the surface of the cell membrane. The message is an antigen, a protein fragment taken from an invading microbe. A series of events unfolds that results in the production of many clones of the helper T cell. These identical T cells can serve as a brigade forming an essential communication network to activate B cells, which make antibodies that will specifically attack the activating antigen.

  • Lactose Digestion in Infants

    Lactose Digestion in Infants

    Animations

    (53 sec) The lactase enzyme is produced in the small intestine of infants. It digests lactose by breaking it into glucose and galactose.
