Fungal infections can be acquired by inhalation, ingestion, or through the skin (for example, through a cut or wound). Some fungal infections can cause disease in otherwise healthy animals, while others require a host that is sick, weakened, or immunocompromised to establish infection.
The heart is at the center of your circulatory system, which is a network of blood vessels that delivers blood to every part of your body. Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly. Your heart is a muscle, and its job is to pump blood throughout your circulatory system.
The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels. Veins are blood vessels that carry blood from the body to the heart. Arteries are blood vessels that carry blood away from the heart to the body. A Healthy Heart Cross-Section
