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.
Blood passing through the left side of the heart is kept. separate from blood passing through the right side of the. heart. Thus, the human heart is actually a double pump, right. and left. The right heart receives blood from the systemic. veins and pumps the blood into pulmonary arteries going to. the lungs. The left heart receives blood coming from the. lungs by way of the pulmonary veins and pumps the blood to. the rest of the body. Fig.
