The Cardiovascular System Flashcards
Parts of a heart? (16)
Super Vena Cava
Inferior Vena Cava
Left Pulmonary Artery
Semi Lunar Valve
Bicuspid Valve
Aorta
Right Pulmonary Vein
Tricuspid Valve
Left Ventricle
Right Atrium
Semi Lunar Valve
Right Ventricle
Left Atrium
Right Pulmonary Artery
Left Pulmonary Vein
Septum
How blood travels through the heart? (8)
- Right atrium
Deoxygenated blood flows into the RA through the VENA CAVA. - Right ventricle
Blood is pumped into the right ventricle.
Right ventricle contracts and pumps the blood to the lungs. - Left and right Pulmonary Artery
These arteries transport deoxygenated blood to the lungs. - Left and right lungs
Gaseous exchange occurs at the left and right lungs. - Pulmonary Vein
Transports oxygenated blood to the left atrium. - Left atrium
Receives oxygenated blood and pumps it into the left ventricle. - Left ventricle
The heart contracts and the left ventricle pumps oxygenated blood to the body’s organs and tissues via the AORTA. - Organs and tissues
Gaseous exchange occurs and the organs and tissues.
Functions of the Cardiovascular System (5)
Transport of oxygen
Transport of carbon dioxide
Transport of nutrients
Control of body temp
Clotting of blood
Where is oxygen transported to the body and how does it effect your body and relate to sports? (sprint in rugby)
Moves oxygen (O2) to the working muscles and organs.
Increased rate of oxygen (O2) during exercise
As you begin to sprint in rugby the blood delivers the extra oxygen needed to the muscles/organs
Where is carbon dioxide transported to the body and how does it effect your body and relate to sports? (2000m row)
Removes Carbon Dioxide (CO2) waste product
During a 2000m row the carbon dioxide is removed from the body through breathing, this enables the body to speed up the oxygenation of the blood.
Transport of Nutrients - where and how does it help you body and improve your performance?
Nutrients are moved around in the blood
The nutrients enable the body to recover after exercise or training. Therefore, you can train more which will aid improvements in performance.
Controlling body temperature.
making sure body temp is at the right level
Clotting of blood and an example? (boxer)
Platelets in the blood clot together to stop bleeding
A boxer who takes a hit to the face may get a cut, however, the platelets will clot the wound therefore they are able to continue to perform.
Types of blood vessels (3)
Arteries
Veins
Capillaries
Arteries (3)
Arteries transport the oxygenated blood away from the left side of the heart.
The largest artery in the body, connected directly to the heart, is the Aorta
Arteries carry blood under a high pressure
Veins (3)
Veins transport blood from all over the body back to the heart and lungs for re-oxygenation.
They are blue because they carry blood that is full of waste products, and are low in oxygen.
Veins carry blood under a low pressure
What is unique about veins?
An unique feature of veins is that they have valves.
Like the valves in the heart, they are there to prevent a backflow of blood.
Capillaries (2)
Capillaries are small blood vessels that carries blood to and from the body’s cells.
They are one cell thick and are exchange points where oxygen and carbon dioxide cross into the tissue cells (muscles) from the arterioles.
Systolic blood pressure (SBP) =
highest pressure within the vascular system during cardiac contraction (contracting/emptying)
Diastolic blood pressure (DBP) =
lowest pressure within the vascular system & when heart is relaxed (relaxing/refilling)
