Cardiovascular System

Cardiovascular System

The heart uses four valves to ensure that the blood flows in only one direction, healthy valves close and open in coordination of the action of your hearts atria and ventricles.

The vascular system can redistribute blood to parts of your body that are in immediate demand of blood and it can also avoid parts of the body that are not in that much demand of blood. 

During my investigation of my heart and my breathing rate, I measured my resting heart rate which was 68 as well as my resting breathing rate which was 28 after that we then went on to play some sports for a couple of minutes to see what would happen after I moved my body around a lot I took my heart rate measurements again but this time I 80 and my breathing rate was 34.

My measurements for my heart rate increased because my body was under constant movement and my body was in demand of more oxygen also my breathing rate increased because my muscles where performing heavy work, when receptors in the brain stem become aware of this they will send signals to the lungs and associated muscles to increase the rate of breathing.

During the exercise our blood pressures increased because of the demand of blood in the muscles without the right amount of blood in the body or the muscles they may seize to function properly.

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.
