Which of the following contains deoxygenated blood?

Option 2 : Pulmonary artery

Concept:

• Pulmonary artery -> carries deoxygenated blood from the right ventricle of the heart to the lungs
• The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration
• The right ventricle mainly receives blood from the right atrium. The right atrium receives deoxygenated blood from all over the body through the superior vena cava, inferior vena cava, and coronary sinus.
• The damage to the Pulmonary artery slows blood flow through the lungs, and blood pressure in the lung arteries rises. The heart must work harder to pump blood through the lungs. The extra effort eventually causes the heart muscle to become weak and fail.

• Subclavian artery -> is one of the large artery that supplies blood to the upper limbs, as well as parts of the head and neck. Further during the blood supply the subclavian artery is divided into three parts which are described relative to the anterior scalene muscle.
• Pulmonary veins -> main function is to transport oxygenated blood from the lung alveoli into the left atria. Other veins also exist in the pulmonary system. The bronchial arteries and veins are the vessels responsible for delivering oxygen and carrying away carbon dioxide to the lung tissue itself.
• Aorta -> is the main artery that carries blood away from the heart to the rest of other body. The blood leaves the heart through the aortic valve. Then it travels through the aorta, making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles and other cells.
