which of the following receives
0:01
oxygenated blood from the lungs option a
0:04
pulmonary artery option b pulmonary vein
0:07
option C Iota option D tricuspid valve
0:19
now the answer is pulmonary vean and
0:22
this is the pulmonary vean that carries
0:25
oxygenated blood from the lungs to the
0:27
left atrium of the heart this is your
0:29
score card heart you can watch our 7
0:31
Minute video on heart structure and
0:33
function before attempting this quiz or
0:35
let us move to the second question what
0:38
is the function of the mital valve
0:40
option A prevent back flow option b pump
0:43
blood option C carry oxygen option D
0:54
nutrients the answer is it prevents back
0:56
flow so this is a metal valve that
1:00
into the left atrium from the left
1:02
ventricle during ventricular
1:04
contraction question number three which
1:07
chamber pumps deoxygenated blood to the
1:09
lenss option a left ventricle B right
1:13
ventricle C left atrium d right
1:26
atrium the answer is right ventricle so
1:29
this is a right ventricle that pumps
1:31
deoxygenated blood to the lungs through
1:34
this pulmonary artery for
1:37
oxygenation question number four what is
1:39
the largest artery in the body option A
1:42
Iota B pulmonary artery C mital valve D
1:48
veka your time starts
1:56
now answer is Iota so this is iota it is
2:00
the largest artery carrying oxyrich
2:02
blood from the left ventricle to all
2:04
parts of the body question number five
2:07
which valve is located between the right
2:10
atrium and right ventricle option a
2:13
iotic valve B TripIt valve c metral
2:26
valve the answer is stri aspit valve
2:29
TripIt valve is situated between this
2:32
right atrium and right ventricle that
2:35
prevents back flow of blood from right
2:37
ventricle to this right atrium so this
2:40
is a TripIt valve question number six
2:43
left ventricle is involved in a pumping
2:46
deoxygenated blood B pumping oxygenated
2:49
blood C receiving blood D filtering
2:52
blood your time starts now
3:02
answer is pumping oxygenated blood and
3:04
this is a left ventricle that pumps
3:06
oxygenated blood to the body through
3:09
this Iota question number seven which
3:12
structure carries deoxy blood from the
3:15
upper part of the body option A inferior
3:17
vena B superior vena C Iota D pulmonary
3:31
the answer is superior veneka superior
3:33
vena carries deoxy blood from the upper
3:36
part of the body to the right
3:39
atrium question number eight what is the
3:41
function of the pulmonary arteries
3:44
option a carry oated blood option b
3:47
carry deoxygenated blood option C filter
3:50
waste option D regulate pressure
4:01
the answer is carry De oxinate Blood so
4:04
this is a pulmonary artery that carries
4:06
de oxinate blood from the right
4:08
ventricle to the length for
4:12
oxygenation question number nine which
4:14
chamber receives deoxygenated blood from
4:16
the body option a left atrium option b
4:20
right atrium option C left ventricle
4:22
option D right ventricle
4:33
the answer is right atrium so this is a
4:36
right atrium that receiv receives de
4:38
oxinate blood from the body via Superior
4:44
vena question number 10 what prevents
4:47
backflow of blood into the left
4:49
ventricle option a iotic valve B metral
4:52
valve c pulmonary valve D tricuspid
5:05
the answer is the ioic W so this is
5:08
iotic valve that prevents back flow of
5:10
blood into the left ventricle during
5:15
relaxation question number 11 which
5:17
structure carries oxygen rich blood to
5:19
all parts of the body option A Iota
5:23
option b pulmonary artery option C
5:25
inferior vena option D right ventricle
5:35
now the answer is Iota so this is the
5:39
Iota that carry oxygen rich blood from
5:42
the left ventricle and circulates it to
5:45
all part of the body through systemic
5:47
circulation question number 12 what is
5:50
unique about the walls of the left
5:52
ventricle option a thinner than right B
5:55
thicker muscular walls C no walls d elas
6:08
walls the answer is thick muscular walls
6:11
so this is a left ventricle left
6:13
ventricle has thick muscular walls to
6:16
generate high pressure for pumping
6:18
oxidated blood to the
6:21
body question number 13 which vean
6:24
carries de oxinate blood from lower
6:27
parts of the body option A superior vena
6:30
B inferior vena C pulmonary ve D
6:42
Iota the answer is inferior
6:45
vena inferior vena carries de oxinate
6:49
blood from lower parts of the body to
6:52
atrium question number 14 what structure
6:55
allows blood to flow from right
6:57
ventricle to pulmonary artery option a
7:00
iotic valve B TripIt valve c mitral
7:15
valve the answer is pulmonary valve
7:18
pulmonary valve so this is a pulmonary
7:20
valve this valve opens to allow blood to
7:24
be pumped from the right ventricle to
7:26
the lungs for oxygenation
7:29
question number 15 which chamber pumps
7:32
oxygenated blood into systemic
7:34
circulation option A right atrium option
7:37
b left atrium option C right ventricle
7:50
ventricle the answer is left ventricle
7:52
so this is a left ventricle that pumps
7:55
oxygenated blood into systemic
7:57
circulation through this iot
8:00
question number 16 the middle layer of
8:02
the heart wall that enable heart
8:04
contractions is option A pericardium
8:07
option b epicardium option C myocardium
8:18
endocardium the answer is myocardium
8:21
myocardium is a middle thickest layer of
8:23
heartfall composed of cardiac muscle
8:25
fibers that enable heart contractions
8:29
question number 17 one systo and one
8:32
diol constitute one heartbeat which
8:36
about option A 1 second B9 second C8
8:50
second the answer is8 second the heart
8:54
rate of the adult is normally 70 to 75
9:01
question number 18 the rate of heartbeat
9:03
is called by the activ of option a AV
9:06
node B sod the a bundle D parin
9:17
fibers the answer is s a no sinoatrial
9:21
node is a cluster of basemaker cells in
9:24
the right atrium that controls the rate
9:27
of heartbeat question number 19 the test
9:30
that records the electrical activity of
9:33
the heart over a period of time is
9:37
electrocardiogram option b Electro enam
9:50
scan ECG provides information about the
9:53
heart's Rhythm and function and also
9:55
helps to diagnose various cardiac
9:59
and the final question the P wve of ECG
10:02
represents the option A ventricular
10:05
repolarization option b ventricular
10:08
depolarization option C paring
10:10
repolarization option D atrial
10:22
depolarization this is a b wve it
10:25
represents atrial depolarization which
10:28
is electrical activity
10:29
associated with the contraction of the
10:34
Atria hope you are benefited from this
