Vesiekosysteemi

Vesiekosysteemi, also known as the circulatory system, is a vital network of organs and blood vessels that transports nutrients, oxygen, and hormones to cells throughout the body, while also removing waste products. It consists of the heart, blood vessels, and blood. The heart acts as a pump, pushing blood through the arteries to the rest of the body, and then returning it to the heart through veins. The circulatory system is divided into two main circuits: the systemic circuit, which delivers oxygenated blood to the body tissues, and the pulmonary circuit, which carries deoxygenated blood from the body to the lungs for oxygenation. The primary function of the circulatory system is to maintain homeostasis by ensuring that all cells receive the necessary nutrients and oxygen while removing waste products. It also plays a crucial role in immune function, temperature regulation, and the transport of hormones. The circulatory system is supported by a network of blood vessels, including arteries, veins, and capillaries, which vary in size and function to efficiently distribute blood throughout the body.
