Why does your blood pressure go up as we age quizlet?

Why does our blood pressure generally go up as we age? Lung tissue receives nourishment and waste removal from the pulmonary circuit.

Why does blood pressure generally go up as we age?

The increase in blood pressure with age is mostly associated with structural changes in the arteries and especially with large artery stiffness. It is known from various studies that rising blood pressure is associated with increased cardiovascular risk.

What factors are known to cause increases in blood pressure quizlet?

What are the 4 main factors affecting blood pressure? Peripheral resistance, Vessel elasticity, Blood volume and cardiac output. Blood cells and plasma encounter resistance when they contact blood vessel walls.

What is the most important force driving reabsorption at the venous end of a capillary?

The primary force driving fluid transport between the capillaries and tissues is hydrostatic pressure, which can be defined as the pressure of any fluid enclosed in a space. Blood hydrostatic pressure is the force exerted by the blood confined within blood vessels or heart chambers.

What are the new blood pressure guidelines for seniors?

New Blood Pressure Standards for Seniors

The ideal blood pressure for seniors is now considered 120/80 (systolic/diastolic), which is the same for younger adults. The high blood pressure range for seniors starts at hypertension stage 1, spanning between 130-139/80-89.

What are two main factors that determine blood pressure?

The most important factor affecting BP is the diameter of the blood vessel, but vessel length and the viscosity of the blood are also factors. In addition, the greater the blood volume in the vessels, the greater the blood pressure.

What are two factors that determine the degree of blood pressure?

Five factors influence blood pressure:

  • Cardiac output.
  • Peripheral vascular resistance.
  • Volume of circulating blood.
  • Viscosity of blood.
  • Elasticity of vessels walls.

How does position affect blood pressure?

Results: The blood pressure tended to drop in the standing position compared with the sitting, supine and supine with crossed legs. Systolic and diastolic blood pressure was the highest in supine position when compared the other positions.

What is one possible path of blood from the heart?

The blood enters the heart from the body through the superior vena cava and the inferior vena cava. Then the blood enters the right atrium chamber of the heart. The blood then moves through the tricuspid valve (shown as two white flaps) into the right ventricle chamber of the heart.

Why does exercise increase venous return quizlet?

Exercise increases venous return because: the increase in respiratory rate and depth inhibits the action of the thoracic pump. muscle contractions decrease venous return by means of the skeletal muscle pump. blood vessels of the skeletal muscles, lungs, and coronary circulation dilate, increasing flow.

Where is the greatest volume of blood found in the body?

Regarding the distribution of blood volume within the circulation, the greatest volume resides in the venous vasculature, where 70-80% of the blood volume is found. For this reason, veins are referred to as capacitance vessels.
