8. What is MAP? Why is it important?
a. Mean Arterial pressure
i. Average pressure over entire cardiac cycle
ii. MAP= ⅔ DPB + ⅓ SBP
b. Can be used to calculate overall blood flow
c. Important- Needed to supply oxygen for brain and heart
9. Explain blood pressure. 10. What happens to blood flow when it’s hot outside? 11. Know the components and function of blood.

d. Plasma (55-60% of blood volume)
i. Can decrease by 10% with dehydration in the heat
ii. Can increase by 10% with training, heat acclimation
iii. 90% water, 7% protein, 3% nutrients/ions/etc
iv. Albumin- most proficient protein in blood plasma
e. Formed elements (40-45% of blood volume)
i. Red blood cells (erythrocytes: 99%)
ii. White blood cells (leukocytes <1%)
iii. Platelets (<1%)
1. Oxygen carrying capacity: 20 mL O2/100 mL blood *** KNOW IT
12. Review the anatomy of the heart.

13. What happens during systole and diastole?
