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 main parts of the heart are the chambers, the valves, and the electrical nodes. Heart Chambers: There are two different types of heart chambers. The first is the atrium (plural is atria), which receives blood returning to the heart through the veins. The right atrium pumps blood to the right ventricle, and the left atrium pumps blood into the left ventricle. This blood is then pumped from the atrium into the second chamber called the ventricle.
