Homeostasis is the state at which equilibrium is maintained within the body. The body withholds a stable internal environment. This enables it to perform desirably. A chain of organs and organ systems maintain this equilibrium. Almost all Organs in the body are involved in maintaining homeostasis. The circulatory system is a perfect example.
Circulatory system transports nutrients and gaseous substances around the body. The major functional components include the heart blood and blood vessels. The blood vessels include arteries, veins and capillaries. Arteries carry blood to all parts of the body. Blood from arteries is channeled towards blood capillaries. Capillaries are networked within body tissues. Thereafter, veins carry blood back to the heart.
The heart is the central point within the circulatory system. It pumps blood towards all parts of the body via the arteries. The arteries are distributed all over the body for sufficient supply of blood. This blood transports digested food substances and gases to and from body tissues. Veins carry blood back to the heart. Conclusively, the circulatory system is strategically situated in the body. Its position enhances efficient maintenance internal balance.
There are several ways through which circulatory system enhances homeostasis. They include; transportation, temperature control, acid and base control and defense. First, transportation maintains homeostasis. This is done by making sure that substance concentration in body cells is kept at a steady level. Blood acts as a carrier for substances entering the body. These substances are gases and digested food. Besides that, cells manufacture hormones, which are transported via the circulatory system. A balance within the body is encountered.
Secondly, the circulatory system regulates temperature. Blood capillaries can regulate body temperature in at least two ways. One, they may surface towards the skin hence encouraging loss of heat. Second, blood may transmit heat from tissues that are hotter towards those that are cooler including the skin. This enables spread of heat from hotter tissues to cooler ones. Temperature balance contributes to homeostasis balance.
Third, the circulatory system stabilizes the level of acidic and base property in the body. Unstable level of PH as a result of cell activity may occur. The circulatory system chips in. Plasma and red blood cells play a role of a reservoir. They absorb acids and release bases when the basic levels are high. It is sometimes difficult for the circulatory system to regulate PH levels. Activities within the urinary and respiratory systems intervene.
The circulatory system also plays a role in defense within the body. Lymph nodes engulf and demolish hazardous chemicals and microbes. This prevents them from spreading throughout the body. The blood and the lymph vessels have white cells. White blood cells move seeking for microbes in order to destroy them. Destruction and removal of harmful microbes and noxious materials improves internal body balance. Homeostasis is achieved.
The structure and component factors of circulatory system enhance homeostasis. The functions carried out by the circulatory system enable the body maintain a stable internal balance. However, there are some roles that it does not carry our perfectly. Other organ systems chip in. These systems are the respiratory and urinary systems. They merge efforts to maintain homeostatic balance. Blood, blood vessels and the heart play a joint role in maintaining internal body balance. The heart mainly pumps blood and vessels carry blood to all parts of the body. However, blood plays a key role.
