Answer 1

Plasma, Red Blood Cells (RBC), White Blood Cells (WBC) and Platelets

Question 2

What is the main function of plasma?

Answer 2

Plasma is the liquid component of the blood, it transports blood cells (WBC,RBC,platelets), nutrients, antibodies, hormones and waste produced during cellular respiration.

Question 3

True or False? The plasma is included in the formed elements of the blood.

Answer 3

False. The RBC, WBC and Platelets make up the formed elements of the blood.

Question 4

Describe the function of the RBC

Answer 4

The red blood cells help to transport oxygen throughout the body and to pick up cell waste (CO2). When it reaches the alveoli in the lungs, it releases the CO2 and picks up a fresh load of oxygen.

Question 5

Describe the function of the Platelets

Answer 5

Platelets help in the process of forming scabs and to heal injuries.

Question 6

Describe the function of the WBC

Answer 6

White Blood cells protect the body; some neutralize pathogens (bacteria, viruses) and others get rid of dead or damages cells.

Question 7

Name the main parts of the circulatory system.

Answer 7

Heart, Arteries, Capillaries, and veins.

Question 8

Name the two types of circulation that occur in the circulatory system.

Answer 8

Systemic circulation and Pulmonary circulation

Question 9

Explain the role of Pulmonary Circulation.

Answer 9

This type of circulation carries blood that contains carbon dioxide to the lungs to get rid of it and reload it with oxygen.

Question 10

Explain the role of Systemic Circulation.

Answer 10

Systemic circulation carries oxygenated blood to the cells of the body to supply them with oxygen and nutrients. It also collects their waste products: carbon dioxide and water.

Question 11

Describe the function of a main part of the circulatory system: The Heart

Answer 11

The heart is a muscle that acts like a pump and pushes blood by contracting over 60 times per minute.

Question 12

Describe the function of a main part of the circulatory system: The Arteries

Answer 12

Arteries take blood out of the heart. The aorta is the largest artery of the body.

Question 13

Describe the function of a main part of the circulatory system: The Capillaries

Answer 13

Capillaries are small blood vessels where exchanges occur by diffusion between the blood and the cells.

Question 14

Describe the function of a main part of the circulatory system: The Veins

Answer 14

Veins take blood to the heart.

Question 15

What are two ways your body can make antibodies?

Answer 15

By getting the disease or by getting a vaccine.
