Circulatory System 14.36

Front

What is the circulatory system?

Back

The circulatory system is a network that allows blood to flow throughout the body, delivering oxygen and nutrients to cells and removing waste products.

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 high blood viscosity affect blood flow?

Back

High blood viscosity increases resistance in blood vessels, leading to slower blood flow.

Front

What happens to blood pressure when blood vessels narrow?

Back

Narrowing of blood vessels increases blood pressure due to higher resistance against the flow of blood.

Front

What is the primary function of the heart?

Back

The primary function of the heart is to pump blood around the body.

Front

What is the relationship between dehydration and blood viscosity?

Back

Severe dehydration increases blood viscosity, which can lead to increased blood pressure.

Front

What is the effect of low blood pH on blood flow?

Back

Low blood pH can decrease the rate of diffusion through blood vessels, potentially leading to slower blood flow.

Front

What is the role of red blood cells in the circulatory system?

Back

Red blood cells transport oxygen from the lungs to the body's tissues and return carbon dioxide from the tissues back to the lungs.

Front

What is blood pressure?

Back

Blood pressure is the force exerted by circulating blood on the walls of blood vessels.

Front

What factors can affect blood flow in the circulatory system?

Back

Factors include blood viscosity, blood vessel diameter, blood pressure, and overall heart function.
