Questions and Answers

What happens to red blood cells when placed in a high concentration of water?

They maintain their shape due to osmoregulation.
They burst due to excess water intake. (correct)
They become rigid due to salt uptake.
They shrink due to water loss.

How does blood plasma help maintain the balance of concentrations in the blood?

By containing substances like glucose and vitamins. (correct)
By preventing the exchange of gases.
By increasing the blood pressure.
By making blood acidic.

What characterizes the human circulatory system?

It exclusively relies on veins for transportation.
It is a single circulatory system.
It is a double circulatory system. (correct)
It transports blood at constant pressure.

Flashcards

Arteries

Blood vessels that carry blood away from the heart at high pressure.

Veins

Blood vessels that carry blood back to the heart at low pressure.

Double circulatory system

A system where blood passes through the heart twice in one complete circuit.

Osmosis

The movement of water across a cell membrane from high concentration to low concentration.

Study Notes

Blood Circulation

Blood leaves the heart under high pressure in arteries.
Blood returns to the heart under low pressure in veins.
The human circulatory system is a double circulatory system.

Osmosis and Red Blood Cells

Red blood cells placed in a high water concentration will take in water via osmosis.
Without cell walls, red blood cells will burst (lyse).
Blood plasma contains salts and other chemicals to maintain osmotic balance with blood cells.
