  1. Cardiovascular System By: Kanwal Malik, Seireen Hammad, Lemia Essa, Danya & Ferdous Daoud

  2. Introduction • The cardiovascular system is one of the major body systems that makes sure that the muscles and bones are supplied with the proper amount of oxygen and blood.

  3. Why is it important? • The cardiovascular system is important because it carries all of the oxygen, nutrients, hormones, etc to the cells and carries away all the toxins and carbon dioxide away from the cells. Cardiovascular disease is the leading cause of death in the United States. Without the cardiovascular system's functions, we would die in a matter of minutes (in fact, for humans, death is determined by when the heart stops beating).

  4. Organs • The main organs are the heart, arteries, veins, capillaries, and the blood..

  5. Heart • The heart is a muscular cone-shaped organ about the size of a clenched fist of the same person. It is located in the upper body (chest area) between the lungs, and with its pointed end (called the apex) downwards, forwards, and pointing towards the left. The main purpose of the heart is to pump blood around the body.

  6. Arteries • The heart pumps blood out through one main artery called the dorsal aorta. The main artery then divides and branches out into many smaller arteries so that each region of your body has its own system of arteries supplying it with fresh, oxygen-rich blood.

  7. Veins • A vein is an elastic blood vessel that transports blood from various regions of the body to the heart. Veins can be categorized into four main types: pulmonary, systemic, superficial, and deep veins.

  8. Capillaries • A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins. Capillaries are most abundant in tissues and organs that are metabolically active. For example, muscle tissues and the kidneys have a greater amount of capillary networks than do connective tissue.

  9. The Lungs • The lung is a magnificent organ that performs a multitude of vital functions every second of our lives. Breathing is the most essential of these functions. With each breath, the lungs take in oxygen and remove carbon dioxide
