Circulatory/ Cardiovascular System Review

  1. What side of the heart has oxygen-poor blood?

Right

  1. Left What side of the heart has oxygen rich blood?

Left

  1. Which blood vessels take blood to the heart?

Veins

  1. Which blood vessels take blood away from the heart?

Arteries

  1. How many chambers are there in the heart?

4

  1. The lower chambers of the heart are called?

Ventricles (Right & Left Ventricle)

  1. Both upper chambers are called?

Atria (Right & Left Atrium)

  1. Which direction in the heart does blood flow?

Down

  1. What controls the flow of blood from the upper to lower chambers?

Valves

  1. Largest artery?

Aorta

  1. Largest vein?

Vena Cava (Superior/Inferior)

  1. What part of the blood takes oxygen throughout body?

RBC

  1. What part of the body works with your Immune System?

WBC

  1. What connects arteries to veins?

Capillaries

  1. The heart is divided into the left & right sides by a middle wall called?

Septum

  1. What is High Blood pressure & what does the American Heart Association consider high blood pressure?

Blood pressure is the force of blood pushing against the walls of the blood vessels. The AHA considers 140/90 to be high blood pressure that requires medication to help lower.

Blood Pathway

You will not have to know the arteries and veins for the test. You will need to be able to put 1-7 in the proper order.Words in red will be the words know the order for.

  1. Blood leaves the lungs and goes to heart
  • Veintakes to heart
  1. Blood flows into your left atrium
  2. Blood goes into your left ventricle
  3. Blood leaves heart and goes to your body cells
  • Artery takes blood away

Drops off oxygen to cells

  • Vein takes blood back to heart
  1. Blood comes into the right atrium
  2. Blood goes into the right ventricle
  3. Blood leaves the heart and goes to lungs to pick

Short answer: Pick one of the short answer questions to know for the test

  1. Explain one CV disease/disorder, describe the treatment & at least 2 ways to prevent the disease .

ArteriosclerosisAtherosclerosisstroke

Heart AttackHypertension

Easiest to use your group’s CV disease. Information for all CV diseases is also in notes and in the book (Ch14 ,lesson 2)

  1. Give two benefits of a healthy cardiovascular system

Benefits of a Healthy Cardiovascular System

Increased Heart Health

  • The resting heart rate of people who regularly engage in aerobic activity is typically slower.
  • As your cardiovascular conditioning improves, your heart can work efficiently with less effort. This leads to a natural increase in your heart health, which helps protect you from the risk of many heart-related conditions.
  • In fact, the University of Maryland Medical Center notes that those who regularly engage in aerobic activity are 45 percent less likely to develop heart disease than those who are not active.

Weight Loss

  • Weight loss typically accompanies improved cardiovascular conditioning.
  • Aerobic exercise acts as a natural appetite suppressant.
  • Depending upon the combination of your aerobic activity and diet, regular cardio exercise can help you lose weight or maintain a healthy weight.

Increased Energy, Enhanced Mood

  • As you exercise and reap the physical benefits of cardiovascular conditioning, you also receive emotional benefits.
  • The endorphins released during the first 30 minutes of aerobic exercise elevate your mood, and you become calmer as the level of stress hormones in your body is reduced.
  • Additionally, you'll enjoy an increase in energy during and after exercise as your heart pumps oxygen-rich blood throughout your body.
  1. Explain what is a person’s target heart rate for exercising and the purpose of exercising within your target heart rate when doing cardiovascular endurance exercises. Also discuss recovery heart rate and the importance of cool down.

This question is from your heart rate lab in the gym

Resting Heart rate is your heart rate at rest

Target Heart rate is the ideal heart rate to exercise at for cardiovascular exercises (such as running on treadmill, elliptical, jogging) Target Heart Rate is 60%-80% of your maximum heart rate.

Maximum HR is 220 – age (ex: 220- 13 yrs = 207

Target HR would be: 124-166 bpm Meaning if you were 13 yrs old you should try to exercise with your heart rate staying within the 124-166 bpm range.

Recovery Heart Rate is the heart rate slowly returning back to your resting heart rate after exercising. When doing aerobic exercise, it is important to cool down by slowing the pace of your movement and then completing your workout with stretches. This will bring your heart rate down gradually.
