Functions of the circulatory system
Interaction with other body systems
The circulatory system works with the rspiratory system by providing oxygen and nutrients to the body.
The main function of the lymph nodes is to produce lymphocytes to help defend the body against microorganisms and harmful foreign particles and debris.
The main function of the lungs is gas exchange.
The main function of blood vessels if to carry oxygen and nutrients throughout the body.
Functions of the heart
~To Transport nutrients and gases throughout the body
~To protect the body from infection and blood loss
~To help maintain a constant body temperature (thermoregulation)
~To help maintain the fluid balance in the body
Congenital heart disease
Pulmonary heart disease
Rheumatic heart disease
Coronary heart disease-
Causes- Some of the cause of this disease are not enough oxygen rich blood to the heart because of narrowing or blocking of the coronary artery by fatty plaques.
Symptoms- Heart attack
~Death of section of the heart
~Pain or discomfort in chest
Treatments- A stent with a deflated balloon is inserted into the artery through a catheter. The balloon is inflated expanding the stent and widening the artery. Then they take out the balloon and then stent is left in to hold open the artery.
How to keep your circulatory system heathly
~Take vitamin E
~Eat fresh vegetables and fruit to provide your body with lots of antioxidants
~Eat fish instead of red meat because it is better for your heart
~ If you were able to lay all the veins, arteries, and capillaries in an adult body, end-to-end, they would stretch out over 62,500 miles.
~ Due to the heart having its own electrical impulse, it will continue to beat even when removed from the body as long as it has an adequate supply of oxygen.
~On average, the human body has about 5 liters (almost 9 pints) of blood continually traveling through it. A kitchen sink would need to be turned on all the way for at least 45 years to equal the amount of blood pumped by the heart in an average lifetime.
