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 circulatory system of the human body is composed of many large and small blood vessels that transport blood throughout the body. The largest artery in the human body is the aorta. This blood vessel is responsible for pumping oxygenated blood from the left side of the heart to the head and body. The aorta is attached to the left ventricle of the heart.
