Detailed explanation-1: -Without blood, the body’s organs couldn’t get the oxygen and nutrients they need to survive, we couldn’t keep warm or cool off, fight infections, or get rid of our own waste products. Without enough blood, we’d weaken and die.
Detailed explanation-2: -Blood delivers oxygen to all the body’s cells. To stay alive, a person needs healthy, living cells. Without oxygen, these cells would die. If that oxygen-rich blood doesn’t circulate as it should, a person could die.
Detailed explanation-3: -If the circulatory system fails or stops functioning it leads to necrosis and eventually death of an individual caused due to the lack of oxygen, nutrients and build of toxins within the body.
Detailed explanation-4: -The body cells need a continuous supply of oxygen for the metabolic processes that are necessary to maintain life. The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism.
Detailed explanation-5: -The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
