The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium. The other system, the systemic vessels, carries blood…
The brain is protected by the skull (cranium), cerebrospinal fluid and 3 protective membranes (Meninges). The spinal cord is protected similarly but with vertebrae instead of the cranium. The brain is first protected by the skull (cranium). This offers physical protection and so naturally is one of the hardest bones…
