Vessels
The pulmonary artery
Aorta, Superior and Inferior Vena Cava, 4 pulmonary veins and the pulmonary artery
Arteries do not have valves. Veins have valves.The only exceptions are the aortic valve where the aorta leaves the left ventricle of the heart, and the pulmonary valve where the pulmonary artery leaves the right ventricle.
the aorta connects the heart to body.the pulmonary veins and artery connect it to lungs
Pulmonary veins and artery together with their associated capillaries
The pericardial sac (or pericardium) is a dual-walled sac that contains the heart and the roots of the great vessels (vena cavae, pulmonary arteries, pulmonary veins, aorta, brachiocephalic arteries and veins, carotid artery and subclavian artery).
The Aorta, the coronary artery, the coronary vein, the inferior vena cava, the superior vena cava, the pulmonary artery.
The arteries, which are strong, flexible, and resilient, carry blood away from the heart and bear the highest blood pressures THE AORTA...IT THE FIRST "MAJOR" ARTERY THAT LEAVES THE HEART. 2nd would be the Pulmonary Veins (reversed arteries-veins) in the Respiratory system.
The arteries carry blood away from the heart, and the veins to the heart. The main veins connected to the heart are the pulmonary vein and the vena cava, and the main arteries are the aorta and the pulmonary artery.
The systemic arteriole, then the capillaries, the venule, the vein, the vena cava, the heart, the pulmonary artery, the pulmonary arterioles, capillaries, the pulmonary veins, the heart, into the aorta, and back into the artery.
The Aorta is the biggest artery, and the Superior and Inferior Vena Cava are the largest veins.
Arteries and veins are connected to the heart. The aorta and pulmonary artery carry blood away from the heart, and the vena cava and pulmonary vein carry blood to the heart.
