Cardiovascular system TEAS A&P

Question 1

How many chamber does the heart contain:

Answer 1

4 chambers
- Left and right atrium
- Left and right ventricle

Question 2

In the heart, what is the Septum?

Answer 2

In the heart, The Septum separates the left and right chambers.

Question 3

What are blood vessels?

Answer 3

The tubes that carry blood throughout the body

Question 4

In the heart, what are the three major types of blood vessel?

Answer 4

1. Arteries : circulate oxygenated blood away from the heart
2. Capillaries : Connect Arteries and Veins
3. Veins : Circulate Deoxygenated blood back to the heart.

Question 5

Blood:

Answer 5

Carries oxygen and nutrients to cells and carbon dioxide and away waste from cells.

Question 6

What are the two different cycles of contractions of the heart?

Answer 6

Systole & Diastole

Question 7

Systole:

Answer 7

Contraction of the heart: blood is being pumped out of the heart INTO THE ARTERIES. The mitral and tricuspid valves close

Question 8

Diastole:

Answer 8

Relaxation of the heart AKA when the heart fills up with blood, the aortic and pulmonary valves close.

Question 9

What are the hearts different types of electrical system?

Answer 9

1. Sinoatrial Node
2. Atrioventricular Node
3. Bundle of His
4. Left and Right Bundle Branch
5. Purkinje Fibers

Question 10

What is the Sinoatrial Node?

Answer 10

It is the “pace maker” of the heart, produce sinus rhythms and beats within the heart. 90-60 BPM

Question 11

What is the Atrioventricular Node?

Answer 11

beats 40-60 BPM

Question 12

If the Sinoatrial Node were to give up, what would be the back up?

Answer 12

Atrioventricular Node

Question 13

If the atrioventricular Node were to give up, what would be back up?

Answer 13

Purkinje Fibers: 20-40 BPM

Question 14

How does OXYGENATED BLOOD flow throughout the Cardiovascular system?

Answer 14

The heart pumps OXYGENATED BLOOD through the Arteries from the Lungs into the LEFT ATRIUM, down into the LEFT VENTRICLE, into the Aorta to the rest of the body. THE BLOOD THEN FLOWS THROUGH THE CAPILLARIES WHERE IT EXCHANGES OXYGEN AND NUTRIENTS IN THE TISSUES FOR CARBON DIOXIDE AND WASTE AND OXYGEN POOR ARE TRANSPORTED THROUGH THE VEINS BACK TO THE HEART

Question 15

How does DEOXYGENATED blood flow throughout the cardiovascular system?

Answer 15

now that the Nutrients, Wastes and POOR BLOOD(deoxygenated) HAS ENTERED through the veins, it then travels through the right atrium, down into the right ventricle and into the lungs where the carbon dioxide and waste material is released Then oxygen is taken in by the Red blood cells and the entire process repeats

Question 16

Functions of the cardiovascular system:

Answer 16

1.Delivers oxygen and nutrients to the cells of the body and removes carbon dioxide and waste.
2. Maintain body’s blood pressure.
3. Maintaining the body’s pH
5. Transporting hormones
6. Fighting infections
7. Aiding in digestion
8. assisting in repair of damaged tissues.
