8
New cards

How does the skeleton allow movement?

Bones provide surfaces for the attachement of muscles.

Three functions: create movement, maintain posture, produce heat.

16

Muscles pull on bones.

17
New cards

What are the keys to maintaining proper posture?

Flexibility and strength.

18
New cards

They generate heat.

19

Connect muscles to bones.

22
New cards

What is the difference between ligaments and tendons?

Ligaments connect bone to bone; tendons connect muscles to bones.

23
New cards

What is flexion?

A movement that decreases the angle between the bones at a joint.

24
New cards

What is extension?

A movement that increases the angle between two body parts.

25
New cards

What is reciprocal inhibition?

When one muscle contracts, its pair relaxes.

26
New cards

What is an agonist?

The muscle that contracts (shortens).

27
New cards

What is an antagonist?

The muscle that relaxes (lengthens).

28
New cards

What does C.A.r.e.F.u.L stand for?

Stands for Command term, Allocated marks, Focus of question, and Limiting terms. It is a technique to follow when answering questions.

29
New cards

What does the cardiovascular system consist of?

Heart and blood vessels working together to transport gases and nutrients around the body.

30
New cards

What are the four functions of the cardiovascular system?

Circulates blood, transports oxygen and nutrients, transports wastes, maintains stable body temperature.

31
New cards

What are the different types of blood vessels?

Arteries, Capillaries, and Veins.

32
New cards

What is the function of arteries?

Carry oxygen-rich blood from the heart to the body.

33
New cards

What is the aorta?

Largest artery in the body.

34
New cards

What are capillaries?

The smallest type of blood vessel; the site where nutrients and waste are exchanged.

35
New cards

What is the function of veins?

Carry blood with lower oxygen content back to the heart.

36
New cards

What is the size of the adult heart?

The adult heart is about the size of a large fist.

37
New cards

What are the atria?

The upper chambers that receive blood.

38
New cards

The septum divides the heart into two sides.

40
New cards

What is heart rate?

Number of times your heart beats in a given time.

41
New cards

What is the average resting heart rate?

Approximately 72 beats per minute (bpm).

42
New cards

What are the two parts of Vena cava?

Superior vena cava and Inferior vena cava.

43
New cards

Where does the blood move from and what valve is responsible?

Blood moves from the right atrium to the right ventricle and through valve between the atrium and ventricle opens to allow blood to to move into the ventricle.

44
New cards

What happens to the blood during gas exchange?

At the lungs, carbon dioxide is removed from the blood and oxygen is added.

45
New cards

Where does Oxygenated blood travel through via the blood vessel to?

Returns to the heart via the pulmonary vein and into the left atrium.

46
New cards

What happens in body?

Oxygenated blood is transported around the body delivering oxygen and nutrients to the bodies cells and collecting waste.

47
New cards

Where gas exchange takes place and what is the process called?

The exchange of CO2 and O2 between the blood and body cells occurs in capillaries and is called gas exchange.

48
New cards

What does the respiratory system include?

Nose, mouth, throat, voicebox, windpipe, and lungs.

49
New cards

What are the functions of the respiratory system?

Five Functions: Brings air Atmosphere into the lungs, Transfers oxygen from the air into the blood, Removes carbon dioxide form the blood, Expels heat in the air exhaled, Allows the vocal cords to create speech as air is exhaled.

50
New cards

Where are the lungs located?

Located in the chest cavity behind the ribs.

51
New cards

What are alveoli?

What are the two phases of breathing?

Inspiration and Expiration.

54
New cards

Where would high concentration air particles move?

Air particles move where high amount of them (high pressure) to areas where there is a lower amount of them (low pressure).

55
New cards

What happens during inspiration (inhalation)?

Diaphragm contracts, intercostal muscles contract, chest cavity size increases, lung pressure decreases, drawing air into the lungs.

56
New cards

What is Expiration?

Also known as exhalation, air is expelled from the lungs.

57
New cards

What is gaseous exchange?

The process where gases move across a surface without the use of energy.

58
New cards

What is the difference between Inspiration/expiration and gaseous exchange?

Breathing is taking air into the lungs and expelling it from the lungs. Gaseous exchange involves the movement of gases across a surface.
