Respiratory + Cardiovascular Systems

Question 1

What is the function of the Respiratory System?

Answer 1

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

Question 2

What is the function of External Respiration?

Answer 2

Brings O2 from environment into the body

Question 3

What is the function of Internal Respiration?

Answer 3

Transports O2 to all tissues and cells in the body through the blood

Question 4

What is the function of Cellular Respiration?

Answer 4

Uses O2 to break down glucose molecules for energy

Question 5

Answer 6

Trachea, bronchi, lungs

Question 7

What muscles enable breathing and enable expansion of the lungs?

Answer 7

Diaphragm - enables breathing
Intercostal and Accessory muscles - enable expansion

Question 8

In the lungs, what is the process of diffusion?

Answer 8

O2 and CO2 exchanged between air and blood

Question 9

Where does diffusion occur in the lungs?

Answer 9

Alveoli

Question 10

What is Ventilation?

Answer 10

The rate gas enters and leaves the lungs

Question 11

What system controls ventilation?

Answer 11

Autonomic Nervous System

specifically medulla oblongata and pons

Question 12

Answer 12

Aorta, carotid artery, and medulla

Question 13

What factors can affect the respiratory system?

Answer 13

Genetic (Cystic Fibrosis), Environmental (pollutants), Pathogens

Question 14

What is the role of the Cardiovascular (Circulatory) System?

Answer 14

Delivers O2 and nutrients to cells in the body and carries away waste products for removal

Question 15

What parts of the body make up the Cardiovascular (Circulatory) System?

Answer 15

Heart, Blood Vessels, Blood

Question 16

What is the function of Arteries?

Answer 16

blood vessels that carry blood AWAY from the heart

Question 17

What is the function of Veins?

Answer 17

blood vessels that carry blood TOWARDS the heart

Question 18

What is the function of blood?

Answer 18

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

Question 19

Where are red blood cells generated?

Answer 19

Bone Marrow

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

Question 20

Where are white blood cells generated?

Answer 20

Bone Marrow

Question 21

What is the role of White Blood Cells?

Answer 21

Involvement in body’s immune response

Question 22

What is the role of Platelets?

Answer 22

Small structures that heal any ruptured vessels by clotting together

Question 23

Oxygen binds to ____ in RBC.

Answer 23

Hemoglobin

Question 24

What are the 4 chambers of the heart?

Answer 24

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

Question 25

What is the function of the Atria?

Answer 25

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

Question 26

What is the function of the Ventricles?

Answer 26

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

Question 27

What is the function of the Pulmonary Circuit?

Answer 27

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

Question 28

What is the function of the Systemic Circuit?

Answer 28

Delivers oxygenated blood to body

Question 29

What is pulse rate?

Answer 29

Number of heart beats per minute

Question 30
