The circulatory system

The circulatory system is divided into two sections: pulmonary circulation and systemic circulation. The circulatory system is accountable for the transfer of nutrients and essential items throughout the human body. It has involvement in the import of water, oxygen (which fuels the cells), and nutrients into the cell and the export of wastes, and carbon dioxide (which is a byproduct of the cells) out of the cell via the excretory system.

The circulatory system is composed of the following categories: the heart, the blood, and the blood vessels. The components of the circulatory system work in symbiosis to transfer essential amino acids, electrolytes, lymph, gases, hormones, and blood cells throughout the entire body. Within the cells, the circulatory system allows the human body to expose of wastes, stabilize pH, maintain homeostasis, fight against bacterial infections, and stabilize body temperature.
