Blood Vessel Definition Anatomy Function Types Britannica Blood vessel, a vessel in the human or animal body in which blood circulates. the vessels that carry blood away from the heart are called arteries, and their very small branches are arterioles. very small branches that collect the blood from the various organs and parts are called venules, and they unite to form veins, which return the blood to. Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process. blood is both a tissue and a fluid. it is a tissue because it is a collection of similar specialized cells that serve particular functions.

Blood Definition Composition Functions Britannica Capillary, in human physiology, any of the minute blood vessels that form networks throughout the bodily tissues; it is through the capillaries that oxygen, nutrients, and wastes are exchanged between the blood and the tissues. the capillary networks are the ultimate destination of arterial blood from the heart and are the starting point for. The blood supplies them with the oxygen and nutrients they need to function. blood vessels also carry waste products and carbon dioxide away from your organs and tissues. each type of blood vessel serves a different function: arteries: these strong, muscular blood vessels carry oxygen rich blood from your heart to your body. they handle a large. Blood vessels function to transport blood. in general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs. blood vessels also circulate blood throughout the circulatory system. oxygen (bound to hemoglobin in red blood cells. Blood vessel formation occurs via two main mechanisms: (1) vasculogenesis and (2) angiogenesis. vasculogenesis is the process by which blood vessels form in the embryo. interactions between precursor cells and various growth factors drive the cellular differentiation seen with vasculogenesis [2].

The human heart is a pear shaped organ about the size of a fist. it is made up of a special type of muscle called cardiac muscle, which is not found anywhere else in the body. the heart acts as a pump to push the blood throughout the body. the heart is separated into four chambers, or parts. the upper chambers are called atria, and the lower. Figure 20.1.1 – cardiovascular circulation: the pulmonary circuit moves blood from the right side of the heart to the lungs and back to the heart. the systemic circuit moves blood from the left side of the heart to the head and body and returns it to the right side of the heart to repeat the cycle.
