The cardiovascular system is composed of blood, blood vessels, and heart. It is a closed system where the blood is pumped by the heart into the arteries through the capillaries to the veins. The heart pumps the oxygenated blood to the circulatory system of the body in order to provide oxygen and remove carbon dioxide from the body. The heart comprises of three main blood vessels, namely, the arteries, veins, and the aorta. The arteries carry oxygenated blood from the heart to the tissues of the body. The veins carry deoxygenated blood to the heart to purify the blood.

(This is a 2-part work, Part 1 is done, only Part 2 is to be worked on at the bottom)Part 1 (Done): Describe the levels of structural hierarchy for the human body, starting with the organismal level and ending with the chemical level. In addition, you should make sure you link each level to the previous level, emphasizing the structural relationships. The human body is organized into a structural hierarchy that progresses from the macroscopic organismal level down to the microscopic chemical level. Each level builds upon the previous one, creating increasingly complex structures. Below is the hierarchy, from largest to smallest, with explanations linking each level to its predecessor: 1. Organismal Level The entire living human body.Relationship: All lower levels work together to sustain life at this highest level. 2. Organ System Level Groups of organs working together to perform major functions.Examples: circulatory, nervous, digestive systems.Relationship: The organismal…
