Arteries: are large blood vessels that carry blood away from the heart.
Veins: conduct blood, that has given up most of its oxygen, toward the heart from the tissues.
Capillaries: carry nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells]]> 2022-07-19 20:30:18 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246392460 Heart Valves prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246398066 There are 4 valves located inside of the heart: Mitral Valve, Aortic Valve, Tricuspid Valve and Pulmonary Valve.
Mitral Valve: is the valve between the left atrium and the left ventricle.
Aortic Valve: closes to prevent return of aortic blood to the left ventricle.
Tricuspid Valve: is located between the right atrium and the right ventricle.
Pulmonary Valve: is the valve positioned between the right ventricle and the pulmonary artery. ]]> 2022-07-19 20:46:59 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246398066 Chambers of the Heart prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246399967 The heart consists of 4 chambers: Right Atrium, Left Atrium, Right Ventricle and Left Ventricle.
Atrium: one of two upper chambers of the heart. 
Ventricle: one of two lower chambers of the heart.]]> 2022-07-19 20:53:57 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246399967 Septa and Layers of Heart Wall prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246404607 There are 2 septa separating the 4 chambers of the heart: interatrial septum and interventricular septum.
Interatrial septum: separates the two upper chambers, atria.
Interventricular septum: lies between the two lower chambers, ventricles.
There are 3 layers of heart walls: the endocardium, the myocardium and the pericardium.
Endocardium: lines the interior of the heart and heart valves.
Myocardium: the middle, muscular layer of the heart wall and is the thickest layer.
Pericardium: a fibrous and membranous sac that surrounds the heart. Composed of 2 layers: the visceral pericardium and the parietal pericardium. ]]> 2022-07-19 21:11:41 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246404607 Superior Vena Cava prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246415347 2022-07-19 21:52:16 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246415347 Inferior Vena Cava prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246415530 2022-07-19 21:53:04 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246415530 Right Atrium prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246415954 2022-07-19 21:54:57 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246415954 Tricuspid Valve prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416133 2022-07-19 21:55:57 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416133 Right Ventricle prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416441 2022-07-19 21:57:17 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416441 Pulmonary Valve prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416601 2022-07-19 21:58:06 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416601 Pulmonary Artery prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416805 2022-07-19 21:59:06 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416805 Lungs prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416935 2022-07-19 21:59:48 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246416935 Pulmonary Vein prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417154 2022-07-19 22:00:51 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417154 Left Atrium prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417326 2022-07-19 22:01:36 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417326 Mitral Valve prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417512 2022-07-19 22:02:26 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417512 Left Ventricle prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417698 2022-07-19 22:03:19 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417698 Aortic Valve prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417799 2022-07-19 22:03:56 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417799 Aorta prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417990 2022-07-19 22:04:37 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246417990 Arteries all over the body prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246418269 2022-07-19 22:05:52 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246418269 Capillaries prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246418405 2022-07-19 22:06:29 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246418405 Veins prwsk9tgrs https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246418508 2022-07-19 22:06:58 UTC https://padlet.com/prwsk9tgrs/7pclke7l90zeg4ec/wish/2246418508
