Q

Sinoatrial (SA) node

A

A specialized area of cardiac tissue, located in the right atrium of the heart, which initiates the electrical impulses that determine the heart rate often termed the pacemaker for the heart.

Q

Atrioventricular (AV) node

A

A small mass of specialized cardiac muscle fibers, located in the wall of the right atrium of the heart, that receives heartbeat impulses from the sinoatrial node and directs them to the walls of the ventricles.

Q

Right vs Left side function in the heart.

A

The right side is “pulmonic” it receives deoxygenated blood and pumps it to the lungs.

The left side is “systemic” because it receives oxygenated blood from the lungs and pumps it to the rest of the body.

Q

Blood

A

Fluid that circulates in the heart, arteries, capillaries, and veins, carries nutrients and oxygen to all parts of the body, and also rids the body of waste products.

16
Q

What are the three types of cell in the blood

A

Red blood cells, white blood cells, and platelets

17
Q

Support Mechanisms of blood

A

Transportation
- oxygen and nutrients around body
- waste products away from tissues
- hormones to organs and tissues
- carries heat throughout the body
Regulation
- Regulates body temperature and pH balance in the body
Protection
- Protects the body from excessive bleeding by clotting
- Contains specialized immune cells to help fight disease and sickness

18
Q

Blood Vessels

A

Network of hollow tubes that circulate blood throughout the body.

19
Q

What are the three types of blood vessels?

A

Arteries, Veins, and Capillaries.

20
Q

Arteries

A

Blood vessels that carry blood away from the heart

21
Q

Capillaries

A

The smallest blood vessels, and the site of exchange of chemicals and water between the blood and the tissues.

22
Q

Veins

A

Blood vessels that transport blood from the capillaries toward the heart.

23
Q

Arterioles

A

Small terminal branches of an artery, which end in capillaries.

24
Q

What is the largest artery in the body

A

The Aorta.

25
Q

Venules

A

The very small veins that connect capillaries to the larger veins.

26
Q

The Respiratory System

A

A system of organs (the lungs and respiratory passageways) that collects oxygen from the external environment and transports it to the bloodstream.

27
Q

.Function of the Pulmonary System

A

To bring oxygen into the lungs and remove carbon dioxide from the lungs to the outside air. It odes this to ensure proper cell function.

28
Q

Respiratory Pump

A

Composed of skeletal structures (bones) and soft tissues (muscles) that work together to allow proper respiratory mechanics to occur and help pump blood back to the heart during inspiration.

29
Q

Respiratory Pump Skeletal Structures

A

Sternum
Ribs
Vertebrae

30
Q

Inspirational Muscular Structures of the Respiratory Pump

A

Diaphragm
External intercostals
Scalenes
Sternocleidomastoid
Pectoralis minor

31
Q

Expirational Muscular Structures of the Repiratory Pump

A

Internal intercostals
Abdominals

32
Q

Inspiration

A

The process of breathing air in.

33
Q

Exspiration

A

The process of releasing air from the lungs and body

34
Q

Function of respiratory airways

A

Allow incoming air to be purified, humidified, and warmed or cooled to match body temperature.

35
Q

Conducting Airways of Respiratory Passages

A

Nasal Cavity
Oral Cavity
Pharynx
Larynx
Trachea
Right and left pulmonary bronchi
Bronchioles

36
Q

Respiratory Airways

A

Alveoli
Alveolar sacs

37
Q

Diffusion

A

The process of getting oxygen from the environment to the tissues of the body. This process happens in the alveolar sacs
