Which of the following is a function of blood in maintaining homeostasis?

Transport of oxygen and nutrients

Which component of blood is less than 1% of its composition?

White blood cells and platelets

How does blood help in protection within the body?

By carrying antibodies and white blood cells to infected tissues

How does the shape of a red blood cell contribute to its function?

It is flattened and biconcave, increasing surface area for gas exchange.

It is spherical, allowing it to store more oxygen.

It is cylindrical, helping it move faster through blood vessels.

It is triangular, providing structural support.

What is hematopoiesis?

The destruction of blood cells.

The transportation of nutrients.

The regulation of body temperature.

Which hormone regulates hematopoiesis and where is it made?

Erythropoietin, made by the kidneys and liver.

Adrenaline, made by the adrenal glands.

Thyroxine, made by the thyroid gland.

What role do platelets play in hemostasis?

They form a plug at the damage site

How is blood type determined?

By the presence of A and B agglutinogens

What is the definition of blood flow?

The volume of blood flowing through a blood vessel, organ, or the entire circulation system in a given period

The force per unit area exerted on a vessel wall by the blood inside it

The opposition to flow; the amount of friction the blood encounters as it passes through the blood vessels

Blood vessels that carry blood away from the heart

What does blood pressure refer to?

The force per unit area exerted on a vessel wall by the blood inside it

The volume of blood flowing through a blood vessel, organ, or the entire circulation system in a given period

The opposition to flow; the amount of friction the blood encounters as it passes through the blood vessels

Smaller blood vessels that branch off of arteries and feed into capillary beds in our different organs and tissues

What is resistance in the context of blood flow?

The opposition to flow; the amount of friction the blood encounters as it passes through the blood vessels

The dynamic structures that create pathways that constrict and relax in order to transport blood throughout the body
