The superior vena cava brings deoxygenated blood from body parts located above the heart such as the head and arms. The inferior vena cava is the largest vein in the human body. It carries deoxygenated blood from body parts located below the heart, such as the abdomen and legs. The coronary...

What is the purpose of the azygos system of veins? a) To carry deoxygenated blood from the intercostal veins to the superior vena cava. b) To carry deoxygenated blood from the renal veins to the superior vena cava. c) To carry deoxygenated blood from t ...
The lymphatic ducts take the lymph into the right and left subclavian veins, which flow into the superior vena cava. Lymphatic vessels vs. blood vessels The lymphatic vessels should not be confused with blood vessels. First of all, the lymphatic system is a one-way street starting blindly in...
The right side of the heart Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the ope...

The Thorax is an irregularly shaped cylinder with a narrow opening, called as superior thoracic aperture; and inferiorly it is a relatively large opening called as inferior thoracic aperture. The superior thoracic aperture is open from where it enables the continuity of the thorax together with the...
The external structure of the heart has many blood vessels that form a network, with other major vessels emerging from within the structure. The blood vessels typically comprise the following: Veins supply deoxygenated blood to the heart via inferior and superior vena cava, and it eventually ...
These lead to the superior vena cava, which is the endpoint for all of the blood coming from the brain and the upper body, as well as from the arms. In the arms, the radial and ulnar veins come together to form the brachial vein, while in the legs, large veins such as the femoral...
BACKGROUND OF THE INVENTION In the normal human heart, the sinus node, generally located near the junction of the superior vena cava and the right atrium, constitutes the primary natural pacemaker initiating rhythmic electrical excitation of the heart chambers. The cardiac impulse arising from the ...
