Intro Circulatory System Postless

What is the main function of circulatory system?

• Regulating body temperature
• Producing hormones
• Digesting food
• Transport substances

What is single circulatory system?

• Blood flows through two separate hearts in the body

• Blood flows through the heart once in each complete circuit of the body

• Blood flows through the heart twice in each complete circuit of the body

• Blood flows in opposite direction in the body

What is double circulatory system?

• Blood passes through the heart twice in one complete circuit of the body

• Blood passes through the lungs twice in one complete circuit of the body

• Blood passes through the heart once in one complete circuit of the body

• Blood passes through the lungs once in one complete circuit of the body

What are the two circulation in the double circulatory system?

• Pulmonary circulation and systemic circulation
• Pulmonary circulation and lymphatic circulation
• Arterial circulation and capillary circulation
• Cardiac circulation and venous circulation

What is pulmonary circulation?

• Circulation of blood between the heart and the lungs

• Circulation of blood between the heart and the brain

• Circulation of blood between the lungs and the liver

• Circulation of air in the body

What is systemic circulation?

• Circulation of blood from the heart to the rest of the body and back to the heart

• Circulation of blood from the heart to the brain and back to the heart

• Circulation of blood from the lungs to the heart

• Circulation of blood within the heart only

Why double circulatory system is more efficient than single circulatory system?

• It requires more energy to function

• It delivers blood slower because of lower blood pressure

• It delivers blood faster because of higher blood pressure

• It leads to mixing of oxygenated and deoxygenated blood

What is human circulatory system consists of?

• lungs, veins, arteries
• brain, spinal cord, nerves
• stomach, intestines, liver
• heart, blood vessels, blood

What are the types of blood vessels?

i) arteries

ii) lymph

iii) veins

iv) capillaries

v) vessels

• i, ii and iii

• i, iii and iv

• ii, iii and v

• iii, iv and v

• All of the above

True or false: Blood leaving the lungs are low in oxygen

• False
• True
