- Cardiovascular System
- Cardiac values
- Cardiac output(l)
- Quantity of blood leaving the left ventricle per minute
- Stroke volume(ml)
- Quantity of blood leaving the left ventricle per contraction
- Heart rate (BPM)
- Beats per minute
- Cardiac output(l)
- Cardiac cycle
- Superior/ inferior vena cava
- Right Atrium
- AV valve
- Right Ventricle
- Pulmonary artery
- Lungs (gaseous exchange)
- Pulmonary vein
- Left atrium
- Av valve
- Left ventricle
- Aortic valve
- Aorta
- Body
- Semi-lumar valve
- Pulmonary valve
- Aorta
- Aortic valve
- Left ventricle
- Av valve
- Left atrium
- Pulmonary vein
- Lungs (gaseous exchange)
- Pulmonary artery
- Artio-ventricular
- Av valve
- Left ventricle
- Aortic valve
- Aorta
- Body
- Semi-lumar valve
- Pulmonary valve
- Aorta
- Aortic valve
- Left ventricle
- Av valve
- Right Ventricle
- AV valve
- Right Atrium
- Atrial diastole
- Atria fill will blood
- Ventricular diastle
- Ventricles fill with blood
- Atrial systole
- Atria contract
- Ventricular systole
- Ventricles contract
- Superior/ inferior vena cava
- Conduction system
- SA node
- AV node
- bundle of his
- purkinjie fibre
- bundle of his
- AV node
- SA node
- Vasomotor control
- Stimulates the sympathetic nervous system to either vasoconstrict or vasodialate the pre-capillary sphincetrs
- Recieves information from chemorecptors and the baroreceptors
- Oragns
- At rest
- Vasodialation of arteioles ans pre-capillary sphicters
- increases blod flow to the organs
- Duringn exercise
- VCC increases sympathetic simultaion whihc vasoconsricts artioles and pre-acpilary sphncters
- Decreases blood flo to the organs
- At rest
- Vascular Shunt Mechanism
- Process of redistributing the blood suppl in the body during exercse
- At rest
- 15-20% of cardiac output is supplied to muscles
- 80-85% of cardiac output is suppplied to organs
- During exercise
- 80-85% of cardiac outputis supplied to the muscles
- Decrease blood flow to organs
- Same blod supply to the brain
- Increased blood supply to the skin surface during lighter work, but decreased as intensity increases
- At rest
- Process of redistributing the blood suppl in the body during exercse
- Venous Return
- The transport of blood from the capillaries through veins, and then through the vena cava back to the heart
- Arteries - thick muscular wall, oxygenated blood
- Veins - thick muscle, deoxygenated blood
- Capillaries - 1 cell thick, gaseous exchange
- Pre-capillary sphincters - slows blood for gaseous exchange
- Capillaries - 1 cell thick, gaseous exchange
- Veins - thick muscle, deoxygenated blood
- Arteries - thick muscular wall, oxygenated blood
- Muscle pump
- Muscle contraction squeezes blood to the heart
- Pocket valves
- valves that prevent backflow
- Smooth muscle
- walls of the viens
- Respiratory pump
- deeper breathing forces blood tothe heart
- Gravity
- upper body blood flow is sided by gravity
- The transport of blood from the capillaries through veins, and then through the vena cava back to the heart
- Vascular Shunt Mechanism
- Process of redistributing the blood suppl in the body during exercse
- At rest
