All of the following will increase blood flow except
Damm [24]

Answer:

D. Decreasing vessel diameter

Explanation:

Cardiac output is the amount of blood pumped per unit time by heart. Increased cardiac output corresponds to increased blood pressure which will result in increased blood flow. In vasodilation the smooth muscles within the blood vessels relax making them wide hence decreasing vascular resistance leading to more blood flow. Decreased blood viscosity will also decrease the resistance to blood flow.

Decreasing vessel diameter will not increase the blood flow, it will rather restrict it because there will be more resistance to passage of blood due to small space.

The correct answer is a sense of control.

The study of psychological and behavioral processes in health, illness, and healthcare is known as health psychology. Its focus is on comprehending the roles that cultural, behavioral, and psychological factors play in physical health and illness. Direct psychological influences on health are possible. For instance, cumulative effects of environmental stressors that are present over time and impact the hypothalamic-pituitary-adrenal axis can be detrimental to health. A person's health might also be impacted by behavioral variables. For instance, certain actions over time may either improve or hurt health. A biopsychosocial strategy is used by health psychologists. In other words, health psychologists believe that psychological, behavioral, and social processes as well as biological ones all contribute to our state of health.
