CIRCULATORY SYSTEM: PULSE RATE ACTIVITY October 14, 2016

Heart: Pulse Rate? PEOE Activity Exit Card AGENDA

HEART

HEART = A BIG, WET, MUSCLY PUMP

HEART TRANSPORTS nutrients oxygen waste heat hormones immune cells

generates HIGH HYDROSTATIC PRESSURE to pump blood out of the heart, while also generating LOW PRESSURE to bring it back in

WHAT IS A PULSE? Change in the diameter of the arteries following heart contractions (p. 241)

WHAT IS A PULSE RATE? 60-100 beats per minute (bpm)

PULSE RATE ACTIVITY

FOCUS QUESTION What happens to the pulse rate after a physical activity? OR How does physical activity affect pulse rate?

PREDICT

EXPLAIN

OBSERVE

GOALS Observe pulse rate Compare pulse rate to rate after physical activity GOALS

RADIAL ARTERIES CARTOID ARTERIES

1 min 15 sec 1 min 15 sec 3 mins Sit down quietly Exercise * jumping jacks * running up stairs * running on spot * walking Reverse roles with your partner and repeat 1 min 15 sec 1 min 15 sec 3 mins Count your resting pulse Count your new pulse and calculate pulse rate

EXIT CARD Why do you think regular aerobic exercise (training) is important? OR What do you think will happen to the pulse rate after a yoga?
