Cardio A & P

Question 1

1) Left atrium—receives oxygenated blood from lungs via _______ ________
2) Right ventricle—pumps deoxygenated blood to lungs via ________ _______ to release CO2 and receive O2
3) Left ventricle—pumps oxygenated blood via ______ to general circulation

Answer 1

1) pulmonary veins
2) pulmonary artery
3) aorta

Question 2

Blood is pumped from the right side (ventricle) to the lungs via what means?

Answer 2

Pulmonary artery

Question 3

Name the 2 atrioventricular valves & their locations
Name the 2 semilunar valves & their locations

Answer 3

AV valves: PRODUCES S1
Prevents blood from flowing back into atria. Valves open when ventricles relaxes.
Tricuspid- right side between atria and ventricle
Bicuspid (mitral)- left side between atria and ventricle

Semilunar valves: PRODUCES S2
Pulmonary valve- lies between the right ventricle & pulmonary artery
Aortic valve- lies between the left ventricle & aorta

Question 4

What are the (5) areas for listening to the heart?

Answer 4

Aortic- 2nd right intercostal
Pulmonary- 2nd left intercostal
Erb’s Point- 3rd left intercostal
Tricuspid- 4th left intercostal
Mitral- 5th left intercostal

Question 5

What is the Ability of the heart muscle tissue to contract in a rhythmic pattern known as?
1) Where is the heart beat initiated at?
2) The above answer is aka??
3) PACEMAKER are passed to where?
4) What slows impulses to all atrium to complete contraction and allow ventricles to fill?

Answer 5

Electrical Conduction System
1) Sinoatrial valve (SA) located upper part of atrium
2) PACEMAKER
3) (AV) node which is in the lower part of the atrium
4) AV node

Question 6

Blood pressure:
Systole is the Phase of ________– IT is what polarization phase of an EKG?

Answer 6

CONTRACTION
DEPOLARIZATION

Question 7

BLOOD PRESSURE:
DIASTOLE IS WHAT PHASE OF BP? AND ON AN EKG IT IS WHAT POLARIZATION?

What is the period between contraction of the atria or ventricles during which the blood enters the relaxed chambers?

Answer 7

RELAXATION
REPOLARIZATION
DIASTOLE

Question 8

CARDIAC CYCLE- HEART SOUNDS

1st sound = _______ – WHICH IS long duration and low pitch - IT IS heard WHEN?
2nd sound = _______ - WHICH IS short duration and sharp sound – IT IS HEARD WHEN?
WHAT IS AN abnormal condition of ineffective closure of the valves?

Answer 8

LUBB- HEARD WHEN AV VALVES CLOSE
DUBB- HEARD WHEN SEMILUNAR VALVES CLOSE
Murmur

Question 9

+ What are the large vessels in which the heart delivers blood > carries the blood AWAY from the heart?
+ What vessels carry the blood TOWARDS the heart?
+ What smaller vessels deliver blood to the tissues?
+ What vessels allow for an exchange of products between tissues and blood?

Answer 9

Arteries
Veins
Arterioles
Capillaries

Question 10

What circulation system supplies deoxygenated blood to the lungs from the right ventricle and returns oxygenated blood from the lungs to the left atrium?

Answer 10

Pulmonary circulation
(Lungs)

Question 11

What circulation system supplies oxygenated blood from the left ventricle to all parts of the body and returns deoxygenated blood to the right atrium?

Answer 11

Systemic circulation
(The body)
