Verejooksuna

Verejooksuna is an Estonian term that translates to "blood circulation" or "hemocirculatory system." It refers to the continuous movement of blood through the body, driven by the heart. This vital process ensures that oxygen and nutrients are delivered to all tissues and organs, while waste products are removed for elimination.

The circulatory system is composed of the heart, blood vessels, and blood. The heart acts as a pump, forcefully ejecting blood into a network of arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart, branching into smaller arterioles and then into tiny capillaries, where the exchange of gases and nutrients with the body's cells occurs. Deoxygenated blood then returns to the heart through venules and larger veins.

The blood itself is a fluid connective tissue containing red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen, while white blood cells are part of the immune system. Platelets aid in blood clotting, and plasma carries nutrients, hormones, and waste products.

Disruptions to verejooksuna can have serious health consequences. Conditions affecting the heart, such as heart disease, or problems with blood vessels, like atherosclerosis, can impair blood flow. Bleeding, or hemorrhage, is also a significant disruption to the circulatory system, leading to a loss of blood volume and potentially life-threatening situations. Maintaining healthy circulation through diet, exercise, and appropriate medical care is crucial for overall well-being.
