Write the functions of the following structures in heart-Septum, Aorta, Vena cava
Answers
Answer:
The septum separates the atria and ventricles in such a way that it forms a barrier between the heart chambers and this prevents mixing of oxygenated and deoxygenated blood.
The aorta is the main artery that carries blood away from your heart to the rest of your body. After the blood leaves the heart through the aortic valve, it travels through the aorta, making a cane-shaped curve that connects with other major arteries to deliver oxygen-rich blood to the brain, muscles, and other cells.
vein which returns blood to the heart from the head, neck and both upper limbs. The inferior vena cava returns blood to the heart from the lower part of the body. The return of blood via the vena cava can be compromised and cause disease.
Answer:
Septum :- The atrioventricular septum is the middle portion of the cardiac wall that divides the heart into left and right sides. This division takes place over just 10 days in the 4th and 5th week of an embryo's development. Its job is to prevent mixing of oxygenated and unoxygenated blood.
Aorta :- The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle, the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve .Its small branches supply blood to the ribs and some chest structures.
Vena Cava :- The superior vena cava is the large vein which returns blood to the heart from the head, neck and both upper limbs. The inferior vena cava returns blood to the heart from the lower part of the body.
