The circulatory system carries nutrients and waste throughout the body using the heart and blood vessels. The heart pumps deoxygenated blood to the lungs and oxygenated blood to the rest of the body via a double circulatory system. Arteries take blood away from the heart, and veins carry blood towards the heart and also have valves. The capillaries link arteries and veins and have a one cell thick wall to exchange materials between blood and body cells.
hey this is VEDIKA AGRAWAL
This topic is to explain you basics of cardiovascular system mainly focusing on circulatory system i.e. systemic circulation pulmonary circulation and also portal circulation of all types.
some tricks and also there to aid learning
also there is video for easy understanding
the reference of this ppt is essentials of medical physiology by sembulingam

Biology Project [Circulatory System] Vijay Raja Std Vii Navdeep With Soundvijayaswathy
My project was to prepare a presentation on human circulatory system.
This is what it finally looked like .
Hope it comes of some use to you all .

circulatory system, their parts, three kinds of circulation, heart, how does it works, artery, vein, capillary, what is in blood, RBC, function summary
3. The Heart and blood vessels together make up theCirculatory System.
4. How does this system work? lungs pulmonary artery pulmonary vein head & arms aorta main vein Left Right liver digestive system kidneys legs Circulatory System
5. Lungs Body cells Our circulatory system is a double circulatory system. This means it has two parts parts. the right side of the system deals with deoxygenated blood. the left side of the system deals with oxygenated blood.
6. The Heart Artery to Head and Body Artery to Lungs Vein from Head and Body Vein from Lungs Right Atrium Left Atrium valve valve Left Ventricle Right Ventricle
7. The heart beat begins when the heart muscles relax and blood flows into the atria. How does the Heart work? STEP ONE
8. The atria then contract and the valves open to allow blood into the ventricles. How does the Heart work? STEP TWO
9. The valves close to stop blood flowing backwards. The ventricles contractejecting blood from the heart. At the same time, the atria are Relaxing again and filling with blood. How does the Heart work? STEP THREE The cycle then repeats.
10. The ARTERY -carry blood away from the heart. the elastic fibres allow the artery to stretch under pressure thick muscle and elastic fibres the thick muscle can contract to push the blood along.
11. The VEIN Veins carry blood towards the heart. veins have valves to stop the blood from going in the wrong direction. thin muscle and elastic fibres body muscles surround the veins so that when they contract they squeeze the veins and push the blood along the vessel.
12. The CAPILLARY Capillaries link Arteries with Veins they exchange materials between the blood and other body cells. the wall of a capillary is only one cell thick
13. SUMMARY Arteries take blood ______ from the heart. The walls of an artery are made up of thick _________ walls and elastic fibres. Veins carry blood ________ the heart and also have valves. The _________ link arteries and veins, and have a one cell thick wall. away muscular towards capillaries
14. Heart Beat Measure in bpm, beats per minute. Specialised tissues produce electrical signals which flow down through the heart, causing the atria to contract, then the ventricles.
20. Atrial Fibrillation Erratic electrical signals prevent the atria from relaxing (filling) and contracting (ejecting)
21. Ventricular Fibrillation Erratic electrical signals prevent the ventricles from relaxing and contracting. Can be lethal in minutes! An electric shock is required to restore normal rhythm.
23. Implantable Defibrillator Sends an electric shock directly into the heart. Restores normal sinus rhythm if in ventricular tachycardia or ventricular fibrillation.
