Cardiovascular System
Cards (27)
- Heart - pumps blood in the body, surrounded by the pericardium, and divided into 4 chambers by the septa
- The upper chambers of the heart receives blood (right and left Atrium)
- The lower chambers of the heart pumps (right and left ventricle)
- Right Atrium - receives deoxy. blood, pumps blood to right ventricle
- Right ventricle - receives deoxy. blood from the right atrium, pumps blood to the lungs
- Left atrium - receives oxy. blood from the lungs and pumps it to the left ventricle
- left ventricle - receives oxy. blood from the lungs and pumps it to the body
- Arteries - blood vessel that carries blood away from the heart
- Aorta - an artery that carries oxy. blood from the heart to the body
- Pulmonary artery - carries oxygenated blood to the heart
- veins - blood vessel that carries blood back to the heart, generally parallel to the arteries
- superior vena cava - veins that carry deoxy. blood FROM the upper body
- inferior vena cava - carries deoxygenated blood from the lower body
- pulmonary vein - carries oxy. blood from the lungs to the heart
- Capillaries - connects arteries and veins, essential for gas nutrient exchange in the blood
- Heart Valves - ensures one-way of blood
- Pulmonary Valve - right ventricle to pulmonary artery
- Tricuspid valve - right atrium to right ventricle
- Aortic valve - left ventricle to aorta
- Mitral valve - lungs to left atrium
- Red Blood Cells - erythrocytes, picks up oxygen from lungs and transport it to the body's tissues
- White Blood Cells - leukocytes, protects the body from harmful invasion and body cells
- Platelets - thrombocytes, repairs damaged blood vessels, provides growth factors for healing and repair by forming clots to help stop bleeding
- Plasma - liquid component of blood; delivers hormones, nutrients, and proteins; help exchange oxygen and Carbon Dioxide
- Cardiac cycle begins with Systole (contraction of heart muscle, pumping blood) and ends with diastole (relaxation of heart muscle, filling with blood)
- Sphygmomanometer - instrument to measure blood pressure
- Normal BP is 120/80 mmHg
