The circulatory system is an organ system of the body responsible for delivering....
nutrients, oxygen, and hormones and removing waste from all the cells around the body.
nutrients, CO2, oxygen, and waste.
CO2, hormones, & oxygen.
Oxygen, removing waste, and nutrients.
Another name for this organ system would be the.....
vascular system
pulmonary system
cardiovascular system
cardiac system
The three major circulatory system parts include....
heart
blood
hormones
blood vessels
What are three reasons why the heart is the most important organ in the body?
The heart never stops working unlike other organs of the body.
It is a muscular organ located in the chest that continuously pumps blood around the body through the network of blood vessels.
Blood is fluid tissue composed of different types of cells suspended in a liquid known as plasma.
The heart ensures every cell of the body receives nutrients and oxygen through the blood.
The three major types of cells that circulate in the blood are:
White blood cells (or leukocytes).
Platelets (or thrombocytes).
Red blood cells (or erythrocytes).
Yellow blood cells (or eukarycytes).
Which is NOT a major function of blood?
Transporting oxygen and nutrients.
Removing waste.
Protecting the body through the immune system and maintaining a stable internal environment (or homeostasis).
Transporting mRNA from one organ to another.
True or False? Damaged blood vessels are 'clotted' with the help of platelets in the blood until full repair can be undertaken
True
False
A blood vessel is a vessel or tube-like structure inside of which blood circulates. The 3 major types of blood vessels are:
Capillaries
Atriums
Arteries
Veins
What Makes Up the Circulatory System?
Cardiac circuit and the pulmotive circuit.
Pulmonary circuit and systemic circuit.
Pulmonary circuit and the cardiac circuit.
The systemic circuit and the cardiac circuit.
The pulmonary circuit refers to the part of the circulatory system that circulates blood from which side?
The lower side of the heart to the lungs and back to the right side of the heart.
The upper side of the heart to the lungs and back to the lower side of the heart.
The left side of the heart to the lungs and back to the right side of the heart.
The right side of the heart to the lungs and back to the left side of the heart.
What are two reasons for having the pulmonary circuit?
The deoxygenated blood is sent from the heart to the lungs and is returned as oxygenated blood.
This circuit allows CO2 to be released and be exhaled out of the body.
Transports oxygenated, nutrient-rich blood from the left side of the heart to all the different parts of the body.
Returns the blood in the right side of the heart as deoxygenated blood.
The systemic circuit is responsible for two of the following...
The deoxygenated blood is sent from the heart to the lungs and is returned as oxygenated blood.
Returns the blood in the right side of the heart as deoxygenated blood.
This circuit allows CO2 to be released and be exhaled out of the body.
Transports oxygenated, nutrient-rich blood from the left side of the heart to all the different parts of the body.
The Circulatory System is sometimes referred as the Double Circulatory System...
Because both circuits pass through the left and right side of the heart.
Because the blood passes through two different circuits before returning to the heart.
Because blood passes through the heart twice in one cycle, it is returned to the heart once after each circuit.
Because the circuits are in a repeating loop around the heart.
Pick the right answer to fill in the blanks:
Every minute, the heart pumps between ____ times and pumps around __ liters of blood.
80 to 20; 6
30 to 40; 2
60 to 100; 5
100 to 50; 3
What is the correct path through the circulatory system which describes the passage of blood originating in the left leg?
Vena cava → left atrium → right atrium → lungs → left ventricle → right ventricle → aorta
Vena cava → right atrium → left atrium → lungs → right ventricle → left ventricle → aorta
Vena cava → left atrium → left ventricle → lungs → right atrium → right ventricle → aorta
Vena cava → right atrium → right ventricle → lungs → left atrium → left ventricle → aorta
The functions of the circulatory system are essential for all other organ systems including:
The digestive system
Aqueous system
Reproductive systems
Endocrine system
True or false? A person with type AB blood can donate blood to a person with any blood type
True
False
Which heart valves are NOT actively closed by the contraction of muscular structures?
Mitral valves
Semilunar valves
Atrioventricular valves
Tricuspid valves
True or false? Both coronary arteries and pulmonary arteries carry deoxygenated blood away from the heart
True
False
How are human red blood cells adapted to their function?
They are red.
They have a biconvex shape.
They have no nucleus.
