Biology 2.2.2

Question 1

The Human Heart is part of a ___ ___ ___.

Answer 1

Double Circulatory System.

Question 2

What is the ‘Double Circulatory System’?

Answer 2

Oxygenated Blood Leaves the Heart on one Side, & Deoxygenated Blood Enters on the other Side.

Question 3

What are the 4 Chambers of the Heart Called? (4)

Answer 3

-Left Ventricle.
-Left Atrium.
-Right Ventricle.
-Right Atrium.

Question 4

The Right Side of the Heart Pumps Blood to the Lungs for Gas Exchange. This is the ___ Circuit.

Answer 4

Pulmonary.

Question 5

The Left Side of the Heart Pumps Blood under High Pressure to the Body. This is ___ Circulation.

Answer 5

Systemic.

Question 6

What are the Benefits of a Double Circulatory System? (2)

Answer 6

-Blood Travelling through the Small Capillaries in the Lungs Loses a Lot of Pressure, which Reduces the Speed at which it can Flow.

-By Returning Oxygenated Blood to the Heart from the Lungs, the Pressure can be Raised before sending it to the Body, meaning Cells can be Supplied with Oxygenated Blood more Quickly.

Question 7

The Right Side of the Heart Receives ___ Blood from the ___, & Pumps it to the ___. What happens next?

Answer 7

Deoxygenated, Body, Lungs. Oxygen Diffuses into the Blood from the Lungs. Oxyhaemoglobin.

Question 8

The Left Side of the Heart Receives ___ Blood from the ___, & Pumps it to the ___. What happens next?

Answer 8

Oxygenated, Lungs, Body. Oxygen Diffuses into your Body Cells, via the Capillaries.

Question 9

What are the 3 Types of Blood Vessels? (3)

Answer 9

-Artery.
-Vein.
-Capillary.

Question 10

Which Blood Vessels Carry Deoxygenated Blood from the Body to the Heart?

Answer 10

Veins.

Question 11

Which Blood Vessels Carry Oxygenated Blood from the Heart to the Body?

Answer 11

Arteries.

Question 12

Which Heart Chambers are at the Top of the Heart?

Answer 12

Atria.

Question 13

What is the name of the Blood Vessel that Carries Blood from the Heart to the Lungs to get Oxygenated?

Answer 13

Pulmonary Artery.

Question 14

What is the name of the Blood Vessel that Carries Oxygenated Blood out of the Heart, & to the rest of the Body?

Answer 14

Aorta.

Question 15

What is the name of the Blood Vessel that Carries Oxygenated Blood from the Lungs back to the Heart?

Answer 15

Pulmonary Vein.

Question 16

What is the name of the Blood Vessel that Deoxygenated Blood Enters the Heart through?

Answer 16

Vena Cava.

Question 17

What Adaptation does the Heart have that helps it to withstand immense Pressure?

Answer 17

Thick, Muscular, Walls.

Question 18

What is the Group of Cells that Control your Heart Rate Called?

Answer 18

Pacemaker.

Question 19

What are ‘Artificial Pacemakers’?

Answer 19

Electrical Replacements if your Original one stops working correctly.

Question 20

What are the Valves between the Atria & the Ventricles in the Heart Called?

Answer 20

Atrioventricular Valves.

Question 21

What are the Valves in the Middle of the Heart Called?

Answer 21

Semilunar Valves.

Question 22

What Part of the Heart is the Pacemaker Located near?

Answer 22

Right Atria.
