The cardiovascular system is a complex network of veins and main artery's that are channels for blood to freely pass through.Each has its own job to do from distributing oxygen to the lungs to preventing diseases and fighting of viruses.

I found this topic very interesting especially this part of the fetal circulation of how a little life can go on without a pulmonary cycle and then once it gives birth the fetal is changed normal.. Very interesting introduction !

Module 1 Introduction to the Cardiovascular System Topic Introduction to the Cardiovascular System Today on the 17th November 2014 @ 2:47pm i started this course in the beginning of the Module i learnt that the Cardiovascular System is the primary circulatory of the human body. it comprimises three things 1 The Heart 2 Blood 3. Blood Vessels this information im studying seems to be easy enough i guess its when these scientific big names come up that ill have the problem and also processing information as i suffer with fibromalgyia hense "fibro fog" which is harder for me to process but im giving it a go as i just completed a diploma course and i recieved an over all mark of 27 modules 85% out of 100% and passed it as 70% was a pass through to not just completion but a diploma certificate with the MOOC in The University of Tansmania in Australia and so i know i can do it and im extremely happy with myself it was in dementia health science

again today @ 3:15pm i studied further and learnt more this time about the direction flow of arteries and veins and how it works Blood Vessels are the conduits of the Cardiovascular System. they consist and make up a closed system since there is no place in the System where whole blood can leave. ARTERIES generally carry blood from its chambers of the heart to the tissue of the body VEINS carry blood from the tissues to the chambers of the Heart. CORONARY ARTERIES Carry blood from the chambers of the heart inside to the walls of the Heart outside.

THE CIRCULATORY SYSTEM its now 3:48pm and im now learning more in detail about the Circulatory system and how it works. Blood circulation is a two cycle system it envolves both the PULMONARY CYCLE and the SYSTOMATIC CYCLE in which the blood circulates through the two circuits. In the Pulmonary Cycle blood circulates from the heart to the lungs and back to the heart, whereas in the Systematic Cycle the blood circulates from the heart to the rest of the body and back to the heart

Essentially fetal blood flows to and from the placenta there are certain bypasses in the heart to avoid the pulmonary cycle at the time of birth the fetal circulation is changed to the normal pattern wow this is so interesting so far im really and truly enjoying studying with you

It says that there is no place in the system where whole blood can leave but what about menstrual cycles? I may have got the wrong idea here but that is to do with blood clots and then the release of the blood clots so how does that happen if there is no place in the system where whole blood can leave?

The cardiovascular system includes the heart, blood and blood vessels. Is the intercellullar fluid and lymph not part of the circulatory system also?

how should i sign i gail to get the exact point

The cardiovascular system comprises the heart and its circulatory network
