The cardiovascular system plays a vital role in circulating blood throughout the body to maintain human life. The system consists of a heart and blood vessels that help delivers blood containing oxygen and nutrients to the body organs and tissues for function. The heart is a muscular body organ located on the left side of a human chest. The heart has four chambers are known as the right atrium‚ right ventricle‚ left atrium and the left ventricle. Blood travels through the four chambers by the heart

CARDIOVASCULAR SYSTEM OF THE HEAD NECK The cardiovascular system consists of the heart‚ blood vessels‚ and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygen‚ nutrients‚ hormones‚ and cellular waste products throughout the body‚ the cardiovascular system is powered by the body’s hardest-working organ — the heart‚ which is only about the size of a closed fist. Even at rest‚ the average heart easily pumps over 5 liters of blood throughout

The Cardiovascular System The heart is one the primary organs in our body. The cardiovascular (CV) system is made up of the heart‚ the blood and the vessels through which blood travels. The CV system works in sequence with the respiratory system to maintain homeostasis. The heart acts as a pump which move the blood through the blood vessels to the tissues and organs of the body. This allows the CV system to help maintain homeostasis by enabling it to carry out its four major functions

OBJECTIVES: 1. List the organs that compose the cardiovascular system and discuss the general functions of this system. 2. Describe the location‚ size‚ and orientation of the human heart. 3. Define the term cardiology. 4. Describe the structure of the heart in terms of its coverings‚ layers‚ chambers‚ valves‚ and blood vessels. 5. Name the function of serous fluid around the heart. 6. Give another name for epicardium. 7. Describe the structure and function of the interventricular septum.

1. Why do we need a cardiovascular system? Because we need to get oxygen through our system. 2. Make sure you know which circuits the left and right heart pump into (pulmonary or systemic). Also know the status of blood (fully oxygenated or not) at -the aorta: Left‚systematic‚ and fully oxygenated. -a pulmonary vein: Left side‚ pulmonary‚ and fully oxygenated. Goes from the right side of the body(heart) into the (left) pulmonary veins then goes to the left atrium then to the left ventricle then

of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates light energy which hits

Discuss the role of energy in the body and analyse how those two body systems interrelate to perform a named functions. For distinction analyse Energy it is the ability to do work. Energy cannot be destroyed but it can be changed to another form. Without energy we would not be able to growth or move. To stay alive we need regular and permanent supply of energy or else we would die
