Heart and Blood Vessel Disorders Biology Diagrams Blood vessels contain layers of connective tissue, muscle and elastic fibers. Muscles in your blood vessels control how wide they get, which also affects your blood pressure. Vasodilation makes your blood vessels wider and lowers your blood pressure. Vasoconstriction tightens your blood vessels, raising your blood pressure.
With each pulse, blood vessels fluctuate between life-giving roles, making them essential players in our health. Arteries: The Highways of Blood Flow. Arteries are like highways wide, robust, and built for speed. They carry oxygen-rich blood away from the heart to the rest of the body. The Return Path. On the flip side, we have veins, which
Circulatory Pathways Biology Diagrams
The journey might begin and end with the heart, but the blood vessels reach every vital spot along the way. These arteries, veins, and capillaries make for a vast network of pipes. 1. The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries. Blood vessels flow blood throughout the body. Arteries transport blood away from the heart.
Circulatory system. The circulatory system, also called cardiovascular system, is a vital organ system that delivers essential substances to all cells for basic functions to occur. Also commonly known as the cardiovascular system, is a network composed of the heart as a centralised pump, blood vessels that distribute blood throughout the body, and the blood itself, for transportation of
How Your Circulatory System Works Biology Diagrams
Circulatory Pathways. The blood vessels of the body are functionally divided into two distinctive circuits: pulmonary circuit and systemic circuit. The pump for the pulmonary circuit, which circulates blood through the lungs, is the right ventricle.The left ventricle is the pump for the systemic circuit, which provides the blood supply for the tissue cells of the body.
Blood follows a path as it continuously flows through your heart, lungs and the rest of your body. This circulation of blood continues over and over, every second of every day. Your heart and blood vessels make it all happen, and that's why together they're known as your circulatory system. The many parts of your circulatory system work
