There are two major types of blood vessels-those that bring blood towards the heart are called veins and those that carry blood from the heart towards other tissues and organs are called arteries

The thing that gives blood to keep everything alive.

a four-chambered organ, containing two atria and two ventricles. The atria are the receiving chambers, and receive blood from veins. On the other hand ventricles are designed to be efficient pumps, sending blood into arteries

None of the above

Detailed explanation-1: -A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings.
Detailed explanation-2: -Heart Chambers. Your heart chambers are four hollow spaces within your heart. Your upper chambers are called your right atrium and left atrium. Your lower chambers are called your right ventricle and left ventricle. Your chambers work together to manage your heartbeat.
Detailed explanation-3: -What is the heart? The heart is a fist-sized organ that pumps blood throughout your body. It’s the primary organ of your circulatory system. Your heart contains four main sections (chambers) made of muscle and powered by electrical impulses. Your brain and nervous system direct your heart’s function.
Detailed explanation-4: -The four chambers of the heart On each side of the wall, there is a small collecting chamber called an ‘atrium’, which leads into a large pumping chamber called a ‘ventricle’. There are four chambers: the left atrium and right atrium (upper chambers), and the left ventricle and right ventricle (lower chambers).
Detailed explanation-5: -The four-chambered heart provides an efficient solution by keeping oxygenated and non-oxygenated blood separate. The supply of oxygen to the body can also be improved by increasing how often the heart contracts.
