Cardio- vascular System

Challenge ? Name a mechanical system (other than the CV system) that requires a pump and closed-circuit circulation. ______________________ Tell its function - ______________________ Describe/diagram how it works – (this may require research on your part)

Connection - Lab How does activity affect blood pressure? Hypothesis: ___________________________________________ Data Conclusion BPLayingSittingMathStandingWalking (3 min) Running (3 min) Syst olic Dias tolic

Connection The average human heart beats 72 times per minute. How many heart beats in a day? Show your work. The average human heart pumps 7571 liters of blood a day. How many liters is that per minute? Show your work.

Vocabulary - Describe structure/function Blood – Red blood cells – White blood cells – Platelets – plasma Blood Vessels – Arteries – Veins – Capillaries Heart – Ventricle – Atrium – valve Blood Pressure – Systolic – diastolic

ObjectivesNotes 1. Describe the functions of the cardiovascular system Delivers - Removes - 2. Describe the parts and functions of blood 3. Trace the path that blood takes through the heart & body See circulation worksheet 4. Identify and describe blood vessels See Blood Vessel worksheet
