2.2 what goes around comes around

the circulatory system (heart, arteries, veins, capillaries)

Goals

- you will know the difference between veins and arteries

- you will know the three parts of the circulatory system and their organs

- you will know the order of the bloodflow through these three parts

- you will know which parts of the circulatory system are oxygenated and deoxygenated

Thanks to the artery valves, the blood doesn't flow back into the...

1. Ventricles
2. Atriums

The right order in heartbeat is

1. Ventricles - atriums - pause
2. Atriums-Ventricles - pause
3. Pause - atriums - ventricles
4. Pause - ventricles- atriums

Tricuspid valve

Aortic valve

Pulmonary valve

Mitral valve

three types of muscle tissue

voluntary (skeletal) - strong but tires quickly, you control them

involuntary  (smooth) - weaker, but doesn't tire quickly, you can't control them

cardiac muscle - muscle tissue in your heart, combination of the two, doesn't tire quickly, but is strong

muscle tissue
