It is from the word "leuk-" means white and "-cyt" means blood. Hence, it means white blood (cells)

What is the flow of oxygen-rich blood?


Enters the heart from the lungs and goes out to the body

200

What is the function of tricuspid valve?

Closes during ventricular systole to prevent backflow of blood from the right ventricle back into the right atrium

When the body doesn't have enough time to adjust to the change in altitude, it will increase in rate/ depth of breath. Leading to dizziness and weakness. Arterioles dilate for more oxygen transport - blood flow into the capillary bed more-oedema. What happens to the brain when there is oedema?

Oedema in the brain can lead to disorientation.

What features transmit the impulse to contract cells at once ?

Intercalated discs

500

This condition is due to increased blood pressure, causing fluid to leak from the blood vessels to lung tissues and into the air sacs. This disease is known as.....
