Inductive definition of CW complexes. If the largest dimension of any of the cells is n, then the CW complex is said to have dimension n. If there is no bound to the cell dimensions then it is said to be infinite-dimensional. The n-skeleton of a CW complex is the union of the cells whose dimension is at most n.
Deoxygenated blood enters the right atrium through three major veins: the superior and inferior vena cava and the coronary sinus. The superior vena cava returns all of the blood to the heart from tissues superior to the heart in the head, neck, arms and upper thorax.
Best Answer: The heart is divided into left heart and right heart functionally. Left heart:-- Incoming blood vessel: Pulmonary vein. The pulmonary veins are large blood vessels that carry oxygenated blood from the lungs to the left atrium of the heart.In humans there are four pulmonary veins, two from each lung.They carry oxygenated blood, which is unusual since almost all other veins carry deoxygenated blood.he aorta distributes oxygenated blood to all parts of the body through the systemic circulation. Right heart:-- Incoming blood vessel-venae cavae. The superior and inferior vena cava are collectively called the venae cavae. They are the veins that return deoxygenated blood from the body, into the heart.
