Heart

The heart is a muscular organ responsible for pumping blood through the circulatory system. It is crucial for delivering oxygen and nutrients throughout the body. The heart consists of four chambers: two atria and two ventricles. The right side of the heart pumps blood to the lungs to pick up oxygen, while the left side pumps oxygenated blood to the rest of the body. The heart's pumping action is controlled by electrical signals that coordinate the heartbeat. Proper heart function is essential for maintaining overall health. Conditions such as heart disease can significantly impact an animal's quality of life and require medical intervention.
