E7: The Respiratory and Circulatory System Flashcards
It pull in oxygen for body’s cells and get rid of carbon dioxide, a waste product.
Respiratory sytem
Other functions of the respiratory system
- Warms and adds moisture to the air being breathe in
- Protects the body from particles you breathe in
- Allows the ability to talk
- Helps in the sense of smell
- Balances level of acidity in the body
It is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body
Circulatory system
A type of system that consists of the heart and blood vessels
Cardiovascular system or Vascular system
The circulatory system has two divisions
- Systemic circulation or circuit
- Pulmonary circulation or circuit.
The network of blood vessels are the great vessels of the heart including
- Large elastic arteries
- Large veins
- Other arteries
- Smaller arterioles
- Capillaries that join with venules (small veins)
- Other veins.
The circulatory system is closed in _______, which means that the blood never leaves the network of blood vessels
Vertebrates
It is a fluid consisting of plasma, red blood cells, white blood cells, and platelets; it is circulated around the body carrying oxygen and nutrients to the tissues and collecting and disposing of waste materials
Blood
It is a circuit loop from the right heart taking deoxygenated blood to the lungs where it is oxygenated and returned to the left heart
Pulmonary circulation
It is a circuit loop that delivers oxygenated blood from the left heart to the rest of the body, and returns deoxygenated blood back to the right heart via large veins known as the venae cavae.
Systemic circulation
An average adult contains __________ or _______ of blood, accounting for approximately 7% of their total body weight
5 to 6 quarts or roughly 4.7 to 5.7 liters
Blood consists of ?
- Plasma
- Red blood cells
- White blood cells
- Platelets.
What type of system that also works with the circulatory system to provide the nutrients the system needs to keep the heart pumping.
Digestive system
It pumps blood to all parts of the body providing nutrients and oxygen to every cell, and removing waste products.
Heart
Which part of the heart pumps oxygenated blood returned from the lungs to the rest of the body in the systemic circulation
The left heart
Which part of the heart pumps deoxygenated blood to the lungs in the pulmonary circulation.
The right heart
What are the four chambers of the heart
- Left atrium
- Left ventricle
- Right atrium
- Right ventricle
The ______ is the upper chamber of the right side of the heart where the deoxygenated blood returns
Right atrium
The deoxygenated is passed into the _______ to be pumped through the pulmonary artery to the lungs for re-oxygenation and removal of carbon dioxide.
Right ventricle
The _______ receives newly oxygenated blood from the lungs as well as the pulmonary vein
Left atrium
The oxygenated blood is passed into the strong ______ to be pumped through the aorta to the different organs of the body.
Left ventricle
It is the part of the circulatory system in which oxygen-depleted blood is pumped away from the heart, via the pulmonary artery, to the lungs and returned, oxygenated, to the heart via the pulmonary vein
Pulmonary circulation
Oxygen-deprived blood from the ______ and ______ enters the ______ of the heart and flows through the ______ into the _______, from which it is then pumped through the ______ into the ______ to the
lungs.
- Superior and Inferior vena cava
- Right atrium
- Tricuspid valve
- Right ventricle
- Pulmonary semilunar valve
- Pulmonary artery
Gas exchange occurs in the _____, whereby CO2 is released from the blood, and oxygen is
absorbed.
Lungs
The ________ returns the now oxygen-rich blood to the left atrium.
Pulmonary vein
It is a circuit loop that delivers oxygenated blood from the left heart to the rest of the body through the aorta
Systemic circulation
It returns in the systemic circulation to the right
heart via two large veins, the inferior vena cava and superior vena cava, where it is pumped from the right atrium into the pulmonary circulation for oxygenation
Deoxygenated blood
What are the Steps of blood flow?
Steps of blood flow
- Right atrium
- Right ventricle
- Lungs
- Left atrium
- Left ventricle
- Arteries
- Capillaries
- Veins
