A

receives and delivers O2 and remove CO2

also filters particles, produces sound, role in sense of smell, controls temperature + humidity of air in the lungs

16
Q

What is the function of Arteries?

A

blood vessels that carry blood AWAY from the heart

17
Q

What is the function of Veins?

A

blood vessels that carry blood TOWARDS the heart

18
Q

What is the function of blood?

A

Carry gases, nutrients, and waste throughout the body and are exchanged in capillaries

19
Q

Where are red blood cells generated?

A

Bone Marrow

Constantly being replaced by new cells as they only last about 4 months

20
Q

Where are white blood cells generated?

A

Bone Marrow

21
Q

What is the role of White Blood Cells?

A

Involvement in body’s immune response

22
Q

What is the role of Platelets?

A

Small structures that heal any ruptured vessels by clotting together

23
Q

Oxygen binds to ____ in RBC.

A

Hemoglobin

24
Q

What are the 4 chambers of the heart?

A

R Atrium (upper), L Atrium (upper), R Ventricle (lower), L Ventricle (lower)

25
Q

What is the function of the Atria?

A

General: upper chambers that receive blood
R Atrium: receives blood returning from body
L Atrium: receives blood returning from lungs

26
Q

What is the function of the Ventricles?

A

Lower chambers that are more muscular and pumps blood from heart to the rest of the body.

27
Q

What is the function of the Pulmonary Circuit?

A

Carries deoxygenated blood from heart to lungs

CO2 is removed and remaining O2 binds to Hgb, oxygenated blood is taken back to heart and circulated through Systemic Circuit

28
Q

What is the function of the Systemic Circuit?

A

Delivers oxygenated blood to body

29
Q

What is pulse rate?

A

Number of heart beats per minute

30
Q

What is normal pulse rate?

A

60-100 BPM

31
Q

What is Systolic Blood Pressure?

A

Pressure in the arteries when the heart contracts

NL: 120 mm Hg

32
Q

What is Diastolic Blood Pressure?

A

Pressure in the arteries when the heart relaxes

NL 80 mm Hg

A
