Blood pressure within the veins is much lower than within the arteries describe describe the three mechanisms that facilitate the blood to return to the heart and what is considered normal healthy adult red blood pressure at rest and how many Americans have have high blood pressure what are two modifiable risk factors for heart disease what are two non-modified risk factors for heart disease what's the difference between heart attack stroke and peripheral artery disease and what are some common symptoms of those conditions

Describe how Blood Pressure is taken and how it relates to the function of the Heart. List 2 examples of causes for either High or Low Blood Pressure and the treatment used to correct it.
Madhur L.
Describe the following: - Describe all types of arteries and veins in terms of diameter, structure, and their roles. - Differentiate between blood pressure and blood flow. - Briefly describe the four factors that influence peripheral resistance and how this affects hemodynamics. - Briefly describe the two factors that influence heart rate, their influence on cardiac output, and hemodynamics. - Briefly describe the factors that influence blood volume and their influence on hemodynamics.

Blood pressure is involved in which of the following? (Multiple) - the difference between the composition of the tunica media (muscle layer) in veins versus arteries - capillary filtrations and gas exchange in capillaries between the blood and intercellular fluid - regulates the release of epinephrine and norepinephrine in the body - causes the "lub" and "dub" sounds of the heart 2. Which of these answers are true about systole? (Multiple) - ventricle contraction that only moves blood to the systemic circulation - systole contractions only push blood into arteries - it is the top number in a blood pressure reading - when it is complete, the sound of the valves closing makes a "dub" sound 3. Cardiomyocytes are responsible for the beating of the heart, which happens independently of the brain. True/False 4. Chemical interventions, such as vasodilators and vasoconstrictors, can regulate the pace of the heart directly. True/False
