Blood Flow Through The Human Body

This paper is submitted in partial fullfillment of the Associate of Science degree in the Medical Assisting program at Southern Technical College
The heart is made up of four chambers the Right Atrium, Left Atrium, Right Ventricle &

Left Ventricle. Blood flows a particular path through the human body. It moves through

the Pulmonary Circulation which is circulation to the lungs and continues through

Systemic Circulation which is circulation to the rest of the body.

This Two part system’s purpose is to bring oxygen bearing blood to all the tissues of the

Body.

During Pulmonary Circulation blood circulates to and from the lungs to release

carbon dioxide and pick up new oxygen. The veins bring waste rich blood back to the

heart entering the Right Atrium through out two large veins Inferior and Superior Vena

Cava. The Right Atrium fills with waste rich blood and contracts pushing blood out

through a one way valve into the right ventricle. These one way valves are to prevent

Any backflow of blood. The ventricle fills and contracts pushing blood into the

Pulmonary Artery leading to the lungs.

Systemic Circulation is a major part of the overall circulatory system the blood vessels

(arteries, veins, & capillaries) are responsible for the delivery of oxygen and nutrients to

the tissue. Oxygen rich blood enters the blood vessels through the hearts main artery

called the Aorta, forceful contraction of the left ventricle forces blood into the Aorta

which branches off into smaller arteries that run throughout the body. The inside layer of

an artery is smooth allowing blood to flow quickly, the outside is very strong so blood

can flow forcefully. Oxygen rich blood enters through capillaries

    The main parts of the cardiovascular system are the heart, blood and the blood vessels (arteries and veins). The function of the heart is to pump blood around the body. The function of the blood is to supply nutrients and oxygen to the cell. The blood vessels (arteries and veins) role is to transport blood to and from the heart. However, the general function of CVS is to remove waste products such as CO2 and protect the body, for example the white blood cells in the body. “It also distributes heat around the body and assists in temperature regulation and helps regulate water.”…

    The myocardium, commonly referred to as the heart, acts as a pump for transporting blood around the body via a collective system, known as the cardiovascular system. This system has various components; blood vessels; mainly arteries, veins and capillaries. The cardiovascular system has four main functions within the body. Firstly to transport dissolved oxygen, hormones, nutrients, salts, enzymes and urea to cells located around various places within the body, whilst at the same time eliminating any waste products such as carbon dioxide and water. Secondly, to protect the body from infection and blood loss. Thirdly, to distribute heat around the body to enable a healthy temperature of 37oc and finally to aid the body to maintain fluid balance. This ‘human pump’ can be regarded as two pumps. The fist sized organ contains two muscular chambers; the upper chamber; the atrium and the lower; the ventricle. The right side of the heart pumps deoxygenated blood from the veins to the lungs for oxygenation, whilst the left side pumps oxygenated blood from the lungs to the body. It is important to note that the two sides are separated by a septum. The blood flows through the heart twice within one cycle, this is known as ‘double circulation’.…

    Right Ventricle- Inferior to the right atrium and it receives deoxygenated blood and ejects it into the pulmonary trunk or pulmonary artery. (Pulmonary trunk branches into right and left pulmonary arteries, which deliver deoxygenated blood to the lungs through a series of vessels called the pulmonary circuit). This is where the blood becomes oxygenated.…

    Moving right along, we now can see the right atria. The right atria is part of the heart, which is the upper chamber, which receives the de-oxygenated blood form our body from the vena cava and is then pumped into the right ventricle of the heart, which is the lower chamber of the heart. After it has done so it will move its way to the lungs under low pressure, which is via the pulmonary artery and there the blood will be turned into oxygenated blood. Between the right atria and the right ventricle…

    Generally, the wall of every vessel is described as being composed of three layers, or tunics. The tunica intima, or tunica interna, a simple squamous endothelium and a small amount of subjacent loose connective tissue, is the innermost layer adjacent to the vessel lumen. Smooth muscle and elastin are the predominant constituents of the middle tunica media, and the outermost tunica adventitia, or tunica externa, is a connective tissue layer of variable thickness that provides support and transmits smaller blood and lymphatic vessels and nerves. The thickness of each tunic varies widely with location and function of the vessel. Arteries, subjected to considerable pressure fluctuations, have thicker walls overall, with the tunica media being thicker than the tunica adventitia. Veins, in contrast, are subjected to much lower pressures and have thinner walls overall, with the tunica adventitia often outsizing the tunica media. Because thinwalled veins conduct blood back to the heart against gravity, valves (not present in arteries) also are present at intervals to…
