Stress has been linked to heart disease in part because the is not activated when the sympathetic nervous system is aroused, and therefore it does not clear the fat and cholesterol from the bloodstream, leading to clogged arteries.

Liver

Explanation:

Liver are part of the organ of the body which is at the right side of a human belly and they can be found in the vertebrates in which they help to detoxifies various metabolites as well as synthesizes proteins leading to them producing biochemicals which are essential for digestion and growth.

Clogged arteries can be defines as the way in which fats and cholesterol are build up on the artery walls which causes obstruction of blood flow or disrupt the flow of blood already exist within their arteries and to the heart muscle by physically clogging the artery.

Heart disease can seen as a disease that affect the heart such as coronary artery disease which is why Stress has been linked to heart disease in part because the LIVER was not activated when the sympathetic nervous system is aroused and as well does not clear the fat and cholesterol from the bloodstream, leading to CLOGGED ARTERIES in humans.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
