PATHOLOGY

Detailed explanation-1: -The cardiovascular system is made up of the heart and blood vessels. It circulates blood throughout the body.

Detailed explanation-2: -Your heart itself is made of muscle nourished by blood vessels. Your heart has four chambers. The chambers are like rooms in the “house” of your heart. If you look at a diagram of a heart, these chambers divide into upper and lower chambers and left and right chambers.

Detailed explanation-3: -The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.

Detailed explanation-4: -Unlike most other organ systems, the function of the cardiovascular system is critical for embryonic survival. Thus, development of the heart and vascular system begins very early, originating from both the embryonic and extra embryonic mesoderm of the embryo. The heart is the first organ to form during embryogenesis.
