Brief description of the cardiovascular system: The cardiovascular system consists of blood, arteries,
the heart, capillaries, and veins. The heart pumps the blood through the body via the blood vessels
which transports water, oxygen and other nutrients to the other organs and parts of the body. Waste is
then transported away as the blood travels from the organs, back to the heart (Colbert, Ankney & Lee,
2013).
Brief description of the respiratory system: The respiratory system is made of the nose, nasal cavity,
sinuses, mouth, throat (pharynx), voice box (larynx), windpipe (trachea), diaphragm, lungs, bronchial
tubes/bronchi, bronchioles, air sacs (alveoli) and capillaries. Air is brought into the body through the
nose and mouth and enters the lungs. The oxygen is then transported into the blood stream (Colbert,
Ankney & Lee, 2013).
The cardiovascular and respiratory system work together by: providing oxygen to the organs of the
body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in
and out of the lungs through the pulmonary arteries and veins that connect to the heart (Smith, C. 2012)
The cardiovascular system adjusts to meet the demands of exercise by (be sure to include
appropriate terminology such as stroke volume, respiration, and pulse): When a person partakes in
physical activity, the demand for oxygen becomes higher. The heart must then speed up in order to
accommodate the body’s increased need for blood and oxygen (Colbert, Ankney & Lee, 2013).
An untrained person’s heart rate and breathing rate would take longer to return to a resting rate
compared to a person who is in good physical condition because their heart has had less time under
tension to build up the stamina. Similar to other muscles in the body, it does not have to work as hard
when it is in good shape and used the training.
Brief explanation of the relationship between heart rate and breathing rate during physical activity:
During physical activity the heart rate and breathing rate increases to make sure that more oxygen is
absorbed into the blood, and more carbon dioxide is removed from it.
, Three contributing factors to coronary artery disease (CAD):
a. Excess Weight
b. Tobacco Use
c. High Cholesterol
CAD leads to dysfunction of the cardiovascular system by constricting blood vessels that supply the
heart with oxygen. When the blood vessels are narrowed it can cause SOB and CP during exercise.
Three contributing factors of chronic obstructive pulmonary disease (COPD)
a. Smoking or second hand smoke
b. Genetics
c. Exposure to smoke, chemicals or other harmful fumes.
COPD leads to dysfunction of the respiratory system by causing inflammation and narrowing of the
lungs, which makes it difficult for air to move in and out of the lungs.
