THE HUMAN BODY CORPORATION

The Veins By Jackson Cross

5 FACTS ABOUT MY ORGAN

1. Veins are thin walled so they collapse when empty

2. Veins are usually closer to the skin than arteries

3. De-oxygenated blood is transfered to the veins to the heart through venules

4. Vein walls are made up of 3 things, membranous tissue, smooth muscle and connective tissue

5. The veins throughout the body support many systems and are important for cardiovascular health and many functions of blood.

5 FACTS ABOUT MY DEPARTMENT

1. The heart beats around 3 billion time in an average human lifetime

2. Within a small drop of blood there is about 5 million blood cells

3. It takes 20 seconds for a blood cell to circulate the body

4. Blood that is rich in oxygen is red while in poor oxygen it is blue

5. The heart is surrounded by a sack called the pericardium

MAIN PURPOSE OF BODY SYSTEM

To deliver oxygen from the lungs to all cells of the body.
To deliver food (nutrients) from the gut to the cell of the body.
To take CO2 from the cells of the body to the lungs (where it changes from dissolved ions to gas)
To transport hormones and blood proteins (such as platelets).
This is all done by the pumping action of the heart in order to pump blood through the arteries, capillaries and veins, around the body.

MY IMPORTANCE

My importance is that if i wasnt here there would be no circulation to the heart causing blood needed in other systems to not be able to get there making them fail as well as our own system.

IF I WAS REMOVED

If i was removed from the HUMAN BODY CORPORATION the blood would be able to be pumped but not be able to get back to the heart causing the heart to fail or be defective which would then make it not able to pump blood to other systems making them fail too. so pretty much the company would not survive.
