Cardiovascular System

The Short Term Effects On The Cardiovascular System


In today's lesson we looked at the short term effects of the Cardiovascular system and how the changes effected your body also how it made you feel after the chosen exercise you did, we also looked at the effects it had on your heart. 

Short Term Effects : 

- One of the short term effects of the Cardiovascular system is the increase of your heart rate during exercise also the increase of heart rate before exercise, this increase is normal it caused by a physiological response from the body, this increase is caused due to the demand of body wanting more oxygen and carbon dioxide and the around the body also wanting to remove carbon dioxide.

- Another one is the amount of blood pumped around the body increases, due to the cause of so much movement of the body during strenuous exercise.

- Oxygenated blood gets pumped around the body during, exercise quickly and carbon dioxide-rich blood gets pumped back into your lungs for exhalation .

- Cardiac Output, the amount of blood the heart pumps out in a minute, during exercise cardiac out put increases depending on the exercise also due to an increase in your heart rate.

- The respiratory System controls the breathing within the body it begins when you draw in air through your nose and mouth. air travels through your wind pipes into both of your lungs giving the lungs a sufficient amount of air to breath in and out.

- During exercise your lungs will start to become exposed to a stronger rush of airflow aerobic exercises in particular expose your lungs to the stronger rush of airflow, aerobic exercise can help clear mucus with in your lungs, mucus build up with in your lungs can decrease the performance of your lungs causing bacterial infections.

  1. You have provided sufficient evidence to describe and explain the short term effects of exercise on he cardiovascular system. However to achieve P1 and M1 you must also describe and explain the changes to the respiratory system.
