Heartworm disease is a serious and potentially fatal condition that affects dogs, cats, and up to 30 other species of mammals. It is caused by parasitic worms (heartworms) living in the major vessels of the lungs and, occasionally, in the heart. The scientific name for the heartworm parasite is Dirofilaria immitis.
During the birthing and nursing processes, puppies and kittens ingest bacteria that make themselves at home in the intestines. Some of these bacteria are beneficial to the pet, and some are potentially harmful. The beneficial bacteria help digest food, produce energy for the cells lining the digestive tract, and help with immune function. They also help keep the potentially harmful bacteria to a minimum.
Roundworms, hookworms, and tapeworms are extremely common parasites that spend their adult lives in the intestines of pets. There are several ways for cats and kittens to become infected with these intestinal parasites.

Most lung tissue is made up of tiny clusters of air “balloons,” called alveoli. Each air balloon is lined by a thin layer of cells in contact with very small blood vessels. When you breathe, air fills the alveoli, and the cells lining the alveoli and the small vessels next to them take in oxygen from inhaled air and release carbon dioxide into the exhaled air.
