Factors that affect Blood Flow

Front

What is blood viscosity?

Back

Blood viscosity refers to the thickness and stickiness of blood, which affects how easily it flows through blood vessels.

Front

How does dehydration affect blood flow?

Back

Dehydration decreases blood flow and increases blood viscosity.

Front

What is blood pressure?

Back

Blood pressure is the amount of force exerted on the walls of arteries as the heart pumps blood.

Front

What happens to blood vessels during vasodilation?

Back

During vasodilation, blood vessels widen, allowing for increased blood flow.

Front

What is the relationship between blood viscosity and resistance in blood vessels?

Back

An increase in blood viscosity leads to an increase in resistance within blood vessels.

Front

What effect does losing a lot of blood have on blood pressure?

Back

Losing a lot of blood decreases blood volume, which in turn decreases blood pressure.

Front

What is the primary function of blood?

Back

The primary function of blood is to transport oxygen, nutrients, hormones, and waste products throughout the body.

Front

What role does heart rate play in blood flow?

Back

An increase in heart rate typically increases blood flow to meet the body's demands, especially during exercise.

Front

What is the significance of maintaining proper hydration for blood flow?

Back

Proper hydration helps maintain optimal blood viscosity and flow, ensuring efficient circulation.

Front

How does exercise affect blood vessels?

Back

During exercise, blood vessels undergo vasodilation to increase blood flow to muscles.
