The Human Heart

It is the strongest part of the bones of the heart and can accommodate mitral valve, aorta and right atrioventricular valve. The fibrous cardiac skeleton has many uses. Probably the most remarkable is protection of heart valves and protection against excessive dilation of heart holes. In addition, the bone of the heart provides many places for the origin and insertion of myocardial fibers. Finally, it electrically isolates the atrium from the atrium. This is necessary for normal heart function.

The heart of the human cardiovascular system is the heart. The size of the fist becomes narrower and the human heart is protected under the chest. It consists of a special and unique myocardium that pumps blood into the body and the heart. Cardiac contraction is caused by intrinsic electrical stimulation that brain and endocrine hormones help regulate. Understanding the basic anatomy and function of the heart is important for understanding the circulatory and respiratory systems of the body. Gas exchange is an important function of circulatory system. Since oxygen and carbon dioxide diffuse directly between their body tissues and the external environment, there is no need for a circulatory system in organisms that do not have specialized respiratory organs such as unicellular organisms. However, in organisms with lungs or sputum, oxygen must be transported from these specialized respiratory organs through the circulatory system to body tissues.

How do you explain the structure and function of the circulatory system of this animal? Unique features are included. The human circulation system is like a recycling system. The heart is the main part of the cardiovascular system. The heart pump helps blood move through the whole body of blood vessels. Blood vessels, including arteries, transport blood from the heart to tissues in the body to make them survive. Veins carry blood from tissues and capillaries to the heart, and capillaries are small veins connecting arteries and veins. The main role of blood in the cardiovascular system is to deliver the substance to all parts of the body, or to transport the substance from all parts of the body.
