The circulatory system is an internal transport system used by living beings to transport nutritive elements into their organism. In the human being the
circulatory system is constituted by a fluid called blood, a set of
conduits (arteries, veins, capillaries) and a driving pump that is the heart.
PARTS:
- · Superior vena cava
- · Pulmonary veins
- · Aorta
- · Pulmonary arteries
- · Inferior vena cava
- · Descending aorta
- · Femoral vein
- · Femoral artery
HOW DOES IT WORK?
The heart pumps blood and sends it all over the body through the veins
arteries and capillaries.
The heart is a muscular structure that contracts regularly and keeps
blood in constant movement within the blood vessels. The blood contains red
blood cells rich in hemoglobin that transports oxygen to all the cells in the
body.
ILNESES:
Diseases and conditions of the respiratory system fall into two
categories: viruses, such as influenza, bacterial pneumonia, enterovirus
respiratory virus; and chronic diseases, such as asthma and chronic obstructive
pulmonary disease (COPD)
DISIES THAT AFFECT THE CIRCULATORY SYSTEM:
ANEURYSM:
An aneurysm is a small bulge shaped balloon and filled with blood that
forms on the walls of blood vessels.
TUMORS:
In a restricted sense, a tumor is any mass or lump that is due to an
increase in the number of cells that make it up. If this cell growth has its
origin in several cells (polyclonal) we speak of hyperplasia and if it is a
cell neoformation that has its origin in a single cell (monoclonal) we call it
neoplasia regardless of whether they are benign or malignant in function of his
ability or not to infiltrate the tissues that surround him.
