Circulatory And Respiratory Flashcards
What does the Aorta do?
Carries oxygen rich blood from the heart to rest of the body
What does the vena cava do?
Brings oxygen poor blood from the upper body Back to the heart
What do the Pulmonary arteries do?
They carry oxygen poor blood from the heart to the lungs to pick up oxygen get rid of Carbon dioxide
What do the Pulmonary veins do?
They bring oxygen rich blood from the lungs back to the heart
What do the atriums do?
Receive blood and pass it to the ventricles
What does the septum do?
Separates the heart into Right and left sides to prevent mixing of oxygen poor and oxygen rich blood
What do the Aortic and pulmonary valves do?
Both aortic and pulmonary valves prevent blood from flowing back into the heart after it’s been pumped out
What do the material valve and tricuspid valve do?
Control the flow of blood between the heart chambers
What does inferior vena cava do?
Carries deoxygenated blood from the lower half of the body back to the heart
What are the important Veins of the body And where are they located
Superior Vena cava- heart, Inferior Vena cava- heart
Functions of the circulatory system
Moves blood, oxygen, nutrients, and waste throughout the body, helping to maintain balance and transport essential substances to cells
What is Atherosclerosis, how does it affect the body, and how can we cure it 
Narrowing of the arteries resulting from plaque buildup, If coronary arteries are blocked, the heart muscle will be deprived of oxygen and nutrients this is what causes heart attacks. Healthy diet can help prevent this along with valve replacement surgery if necessary. 
How does gas exchange occur?
Happens in the lungs where oxygen moves from the air into the blood and carbon dioxide moves from the blood into the air in the tiny air sacs called alveoli 
what do the Bronchi do
They are the main air passages that carry air into the lungs
What does the Epiglottis do?
I flap in your throat the closes when you swallow to prevent your food from entering your windpipe
