Circulatory system

Circulatory System.
Introduction
All the parts o the body needs constant supply of nutrients, oxygen etc. along with other required minerals for the metabolic activities to take place. For this purpose some extra cellular fluids are are continuously flowinf through the body all the time, this fluid is called blood. And the flow of blood is called circulation and the structures and organs which are involved in theis process are called circulatory system.
This helps in balancing a favourable internal environment inside the body, this process is called homeostatis.
Functions of Circulatory system:
Circulatory system helps in the transport of gases
Transportation of O2 from respiratory surface to tissues and CO2 from the tissues to the respiratory surfaces through circulatory system
Circulatory system transport of metabolic waste products
circulatory system transport various metabolic wastes produced from different tissues from which they are transported to arous organs so that they can be removed out of the body
Circulatory system transport of digested food substances
circulatory system absorps and transports digested food from the site of absorption to the different organs of the body of storage, oxidation or synthesis etc
Circulatory system transport of chemical messengers
circulatory system transports the chemical messengers like hormones from the site of their origin to the target organs
Circulatory system helps in tempreture regulation
circulatory system regulates the body tempreture by distributing the heat produced in one part of the body to different parts there by equalizing the body tempreture
Circulatory system helps in transport of metabolic intermediates
The fluid present in the circulatory system carries the various intermediate compounds produced in metabolic reactions from one tissues to another for further metabolism.
Circulatory system helps in protection against the diseases.
The circulatory system produced phagocytic leucocytes that engulf and kill harmful micro organisms.
