"Heart" - what is it, definition of the term
The heart is a vital organ responsible for pumping blood throughout the body, ensuring the delivery of oxygen and nutrients to all tissues while removing waste products such as carbon dioxide. This complex muscular structure consists of four chambers—two atria and two ventricles—which work in coordination through electrical impulses to maintain a constant flow of blood. In dogs, the heart plays a critical role in sustaining life by regulating cardiac output based on the animal's activity level and metabolic demands.
Detailed information
The heart is a complex and vital organ in dogs, functioning as the central component of the circulatory system. It is responsible for pumping blood throughout the body, ensuring that all tissues receive necessary nutrients and oxygen. Located within the chest cavity, protected by the rib cage, the canine heart has a distinct four-chambered structure consisting of two atria and two ventricles.
The right atrium receives deoxygenated blood from the body, which is then pumped into the right ventricle. From there, it is directed to the lungs via the pulmonary artery for reoxygenation. The left atrium collects oxygen-rich blood from the lungs and passes it to the left ventricle, which pumps it out through the aorta to supply the rest of the body with oxygenated blood.
Heart rate in dogs varies based on size and age, typically ranging from 60 to 120 beats per minute at rest. However, during physical activity or periods of excitement, this rate can significantly increase to meet the heightened demand for oxygen and nutrients. Proper heart function is crucial for maintaining overall health and well-being in dogs, making regular veterinary check-ups essential for early detection of any potential issues.
