Answer 3

Cells, tissues, organs, organ systems

Question 4

What is the function of a cell wall?

Answer 4

To protect the cells’ organelles, controls what comes in and out of the cell, acts as the main protection barrier

Question 5

What is the function of cell membrane?

Answer 5

Protects the cell, regulates molecules entering and leaving the cell

Question 6

What is the purpose of cytoplasm?

Answer 6

Help hold the cells organelles in place

Question 7

What is the function of nuclear membrane?

Answer 7

Surrounds the nucleus with a double membrane containing multiple pores

Question 8

What is the role of mitochondria?

Answer 8

Convert oxygen and nutrients into energy

Question 9

What does the vacuole do?

Answer 9

Stores waste products and maintains the PH level of the cell

Question 10

What is the purpose of chloroplasts?

Answer 10

To convert sunlight into energy by a process called photosynthesis

Question 11

What do red blood cells do?

Answer 11

Carry oxygen throughout the body and remove carbon dioxide, which it takes to your lungs for you to breathe

Question 12

Function of nerve cells

Answer 12

Transmit electrical impulses from the brain to the rest of the body and are connected by sensory neurons

Question 13

Function of a muscle cell

Answer 13

Contain protein filaments of action and myosin that slide, producing force and motion

Question 14

What is the function of a male reproductive cell?

Answer 14

To produce, maintain and transport sperm and protective fluid

Question 15

Name 3 specialised cells

Answer 15

Red blood cell, nerve cell, muscle cell, male reproductive cell, root hair cell, photosynthetic cell

Question 16

Why is the pulmonary artery special?

Answer 16

It’s the only artery that doesn’t carry oxygen

Question 17

Why is the pulmonary vein special?

Answer 17

It’s the only vein with oxygen

Question 18

Which direction do veins travel?

Answer 18

To the heart

Question 19

Which direction do arteries travel?

Answer 19

Away from the heart

Question 20

What do capillaries do?

Answer 20

Exchange with the cells and take the carbon dioxide from the cells and give them oxygen

Question 21

What is the function of the dual-circulatory system?

Answer 21

Body -> heart -> lungs

Lungs -> heart -> body

Question 22

Why is it called the dual-circulatory system?

Answer 22

Because two things happen at once, blood flows into the heart, while the blood before is pumped out

Question 23

What is the aorta?

Answer 23

The main artery

Question 24

How many chambers of the heart are there?

Answer 24

4

Question 25

What are the four chambers of the heart?

Answer 25

Left and right ventricle, left and right atria

Question 26

Which side of the heart has oxygenated blood?

Answer 26

Left (on paper would be labeled as the right)

Question 27

Which side of the heart has deoxygenated blood?

Answer 27

Right (on paper it’s labeled as left)

Question 28

Which is stronger and why: atria or ventricle walls?

Answer 28

Ventricle, because it has to pump blood out of the heart, which requires more strength

Question 29

Which ventricle is stronger?

Answer 29

Left (on paper right) because it has to pump oxygenated blood throughout the body, whereas the right (left on paper) only has to pump deoxygenated blood to the lungs which is near the heart

Question 30

What purpose do the valves serve?

Answer 30

They make sure the blood continues flowing forward and doesn’t start going backwards

Question 31

What are the four things transported through blood?

Answer 31

Platelets, plasma, red blood cells, white blood cells
