TPT Cardiovascular System

What is the main function of the cardiovascular system?

• Regulating body temperature.

• Producing red and white blood cells.

• Filtering waste products from the blood.

• Transporting oxygen, nutrients, hormones, and waste products throughout the body.

Which organ is responsible for pumping blood throughout the body?

• The heart is responsible for pumping blood throughout the body.

• The kidneys are responsible for pumping blood throughout the body.

• The lungs are responsible for pumping blood throughout the body.

• The liver is responsible for pumping blood throughout the body.

What are the four chambers of the heart called?

• left atrium, right atrium, left ventricle, and right ventricle

• left chamber, right chamber, upper chamber, lower chamber

• front chamber, back chamber, upper chamber, lower chamber

• main chamber, side chamber, upper chamber, lower chamber

What is the purpose of valves in the heart?

• To filter impurities from the blood

• To produce red blood cells

• To regulate blood pressure

• To prevent backflow of blood and ensure one-directional flow

What is the cardiac cycle?

• The cardiac cycle is the term used to describe the electrical activity of the heart.

• The cardiac cycle is the movement of blood through the arteries and veins.

• The cardiac cycle is the process of blood clotting in the heart.

• The cardiac cycle is the sequence of events that occur during one complete heartbeat.

What is systolic blood pressure?

• Systolic blood pressure is the lowest level of pressure in the arteries when the heart beats and pumps blood.

• Systolic blood pressure is the average level of pressure in the arteries when the heart beats and pumps blood.

• Systolic blood pressure is the highest level of pressure in the arteries when the heart beats and pumps blood.

• Systolic blood pressure is the level of pressure in the veins when the heart beats and pumps blood.

What is diastolic blood pressure?

• Diastolic blood pressure is the measure of the pressure in the arteries when the heart is contracting.

• Diastolic blood pressure is the measure of the pressure in the arteries when the heart is contracting and pumping blood.

• Diastolic blood pressure is the measure of the pressure in the veins when the heart is at rest.

• Diastolic blood pressure is the measure of the pressure in the arteries when the heart is at rest between beats.

What are some common heart diseases?

• Asthma, kidney disease, and stroke.

• Lung cancer, diabetes, and arthritis.

• Coronary artery disease, heart failure, arrhythmia, and heart valve disease.

• High blood pressure, pneumonia, and osteoporosis.

What is the function of red blood cells in the circulatory system?

• The function of red blood cells in the circulatory system is to transport oxygen and remove carbon dioxide.

• The function of red blood cells in the circulatory system is to produce hormones.

• The function of red blood cells in the circulatory system is to fight infections.

• The function of red blood cells in the circulatory system is to regulate body temperature.

How does blood flow through the circulatory system?

• Blood flows through the circulatory system by osmosis, absorbing nutrients from the surrounding tissues.

• Blood flows through the circulatory system in a closed loop, pumped by the heart and traveling through arteries, arterioles, capillaries, venules, and veins.

• Blood flows through the circulatory system by gravity, moving from the feet to the head.

• Blood flows through the circulatory system by diffusion, spreading from the heart to the rest of the body.
