Cat Cardiovascular System
Generally speaking, a cardiovascular system or circulatory system in any living being and cat in particular is where the heart is situated. Also, the system contains the arteries, veins and capillaries that make the blood vessels. The chief responsibility of the cardiovascular system is to circulate blood all over the body with the help of blood vessels that spread throughout the cat’s body. |
A cat’s heart, which is the core of its cardiovascular system, is enclosed in the pericardial sac, a very thin sac, and is positioned in the chest right in between the right and left lungs. The approximate length and breadth of the cat’s heart stretches from the third to the fourth rib of its chest.
Just like in humans, the cardiovascular system of the cat plays an important role. Apart from transporting blood and carrying with it the required nutrients and oxygen responsible for the cat’s healthy bodily functions, the system is also responsible for enriching the cat’s immunity, hormonal balances, and maintaining the right body temperature.
Also, the system ensures the supply of other adequate chemicals to the various tissues and organs of the cat’s body and delivering the waste products and carbon dioxide and thus, helping the body to store normal water and electrolyte levels.
The rhythmic contraction and expansion of the heart is responsible for pumping of blood and transportation of the same through the blood vessels. In cats, the average heart beat per minute is 120. However, the normal range could be anywhere between 110 and 140 beats per minute.
The heart has four chambers, namely the right atrium, the right ventricle, the left atrium and the left ventricle. The two sides of the heart, left and right, are separated by a muscular wall called septum. Apart from this, there are the strong muscular blood vessels called arteries that are responsible for supplying oxygen-rich blood to different parts of the cat’s body. The thin blood vessels called veins do the reverse act of bringing back the blood from the different parts of the body to the heart. The smallest of blood vessels walls called capillaries help in the transportation of oxygen, carbon dioxide, water and nutrients between the blood and the tissues.
