In the cardiovascular system CO2 from tissues goes to the lungs, what are the next steps in this cycle?
|
The O2 from the lungs goes to the respiring tissues where it is used and turned into CO2 which is then transported back to the lungs
|
The cardiovascular system transports metabolites to sites of excretion such as...
|
The kidneys
|
What are the three components of the Cardiovascular System?
|
Hear, Blood vessels, Bloo
|
Heart
|
Serves as a pump that establishes the pressure gradient needed for blood to flow to tissues
|
Blood Vessels
|
Passageways through which blood is distributed from the heart to all parts of the body and back to the heart.
|
Blood
|
Transport medium within which materials being transported are dissolved or suspended.
|
What are the three kinds of circulation?
|
Systemis, Pulmonary, Coronary.
|
Systemic circulation
|
This is the circuit of vessels that carries blood between the heart and the other systems of the body.
|
Pulmonary Circulation
|
This is a closed loop of vessels carrying blood between the heart and lungs.
|
Coronary Circulation
|
Vessels that nourish the heart from outside
|
Do arteries carry blood to or away from the heart?
|
Away from the heart
|
Do veins carry blood to or away from the heart?
|
To the heart
|
What is the basic anatomy of the mammalian heart?
|
Four chambers; 2 atria, 2 ventricles. Divided into the left and right side by a septum.
|
Atrioventricular Valves
|
The right is tricuspid and the left is bicuspid. They are located between the atrium and ventricle to prevent backflow of blood from ventricles into the atria during ventricular emptying.
|
Semilunar Valves
|
Aortic and pulmonary valves that are located at the juncture where major arteries leave ventricles
