Functions of the Heart Parts
100
This system is responsible for bringing oxygen and nutrients to all of the cells in the body, and removes carbon dioxide and waste.
What is the cardiovascular system?
100
These two systems interact closely to deliver oxygen to all of the cells in the body and remove carbon dioxide.
What are the respiratory system AND the cardiovascular system?
100
This organ squeezes and relaxes to move blood through the body.
What is the heart?
100
This is the largest artery that carries blood away from the heart to the body.
What is the aorta?
100
The heart muscles know to contract and beat because of this type of signal.
What is an electric signal?
200
The most important organ in this body system is the lungs.
What is the respiratory system?
200
The urinary system interacts closely with this system to remove waste from the body and create urine.
What is the cardiovascular system? (Blood).
200
These blood vessels carry blood away from the heart.
What are arteries?
200
Several of these structures exist in the heart. They are responsible for opening and closing to let blood flow through the parts of the heart and keep blood from flowing backwards in the wrong direction.
What are valves?
200
The heart is relaxed and filling with blood during this phase of the cardiac cycle.
What is diastole?
300
This system is responsible for protecting the body from external pathogens and fights infections inside the body.
What is the immune system?
300
The blood in the cardiovascular system interacts with this system to obtain nutrients and energy for all the body cells.
What is the digestive system?
300
These blood vessels carry blood towards the heart.
What are veins?
300
This part of the heart is responsible for pumping blood out of the heart to the lungs.
What is the right ventricle?
300
The heart is contracted or squeezed in during this phase of the cardiac cycle?
What is systole?
400
This system contains they kidneys and is responsible for filtering waste out of the blood.
What is the urinary system?
400
White blood cells are considered a part of these two systems.
What are the cardiovascular system and the immune system?
400
These blood vessels bring oxygenated blood from the lungs back to the heart.
What are the pulmonary veins?
400
The valve is located in between the right atrium and the right ventricle. It is made of three flaps.
What is the tricuspid valve?
400
The walls of the left ventricle are much thicker than the walls of the right ventricle for this reason.
The left ventricle must pump blood all over the body, which takes lots of muscle and strength. The right ventricle only needs to pump blood next door to the lungs, so it does not need to be as thick or strong.
500
These molecules are the chemical signals sent by the endocrine system through the body.
What are hormones?
500
The pancreas is a part of these two systems.
What are the endocrine system and the digestive system?
500
These types of signals tell the heart when to contract and squeeze blood.
What are electrical signals?
500
This part of the heart is located in between the left atrium and the left ventricle and is made of two flaps.
What is the mitral valve?
500
There are two separate loops that blood takes as it moves through the heart. Explain these two loops.
Loop one = Blood from the body goes into the right atrium through the superior and inferior vena cava. It then passes through the tricuspid valve into the right ventricle. The right ventricle pumps it out through the pulmonary arteries to the lungs (where it will get oxygenated). Loop two = Blood from the lungs goes into the left atrium through the pulmonary veins. It then passes through the mitral valve into the left ventricle. The left ventricle pumps it out of the heart to the body through the aorta.
