|---|---|---|---|---|---|
| heart rate and force | in general, if heart rate and force increase, blood pressure increases; this is what happens during exercise.
🗑
|
||||
| peripheral resistance | the resistance of the blood vessels to the flow of blood; changes the diameter of arteries have effects on blood pressure.
🗑
|
||||
| elasticity of the large arteries | when the left ventricle contracts, the blood that enters the large arteries stretches the arteries' walls.
🗑
|
||||
| viscosity of the blood | normal blood viscosity depends upon the presence of red blood cells and plasma proteins, especially albumin.
🗑
|
||||
| viscosity of the blood (continue)... | a decreased number of red blood cells, as is seen with severe anemia, or decreased albumin, as may occur in liver or kidney disease, will decrease blood viscosity and blood pressure.
🗑
|
||||
| loss of blood | a small loss of blood, as when donating a pint of blood, will cause a temporary drop in blood pressure followed by rapid compensation in the form of a more rapid heart rate and greater vasoconstriction.
🗑
|
||||
| pulmonary circulation | begins at the right ventricle.
🗑
|
||||
| systemic circulation | begins at the left ventricle.
🗑
|
||||
| renin-angiotensin mechanism | a series of chemical reactions initiated by a decrease in blood pressure that stimulates the kidneys to secrete the enzyme renin; culminates in the formation of angiotensin 2.
🗑
|
||||
| angiotensin 2 | the final product of the renin-angiotensin mechanism; stimulates vasoconstriction and increased secretion of aldosterone, both of which help raise blood pressure.
🗑
|
||||
| vasomotor center | consists of a vasoconstrictor area and a vasodilator area.
