Question 9

activitatea cardiaca

Answer 9

inima prezinta in peretele sau miocardul = muschi striat, de tip cardiac

Question 10

in miocard, cel musculare sunt

Answer 10

a) pot genera impulsuri electric, pot conduce impusuri la celul vecine

b) pot raspunde prin contractii si pot conduce impulsuri la cel vecine

Question 11

a) cele care generez impuls el

Answer 11

formeaza tesut excito-conductor = NODAL (electric)

Question 12

b) cele care pot raspunde prin contractii

Answer 12

formeaz tes mecanic (de lucru)

Question 13

tes NODAL are centrii automatismului

Answer 13

nodul sinoatrial
n. atrioventricular
Fasciculul His + reteaua Purkinje

Question 14

nodul sinoatrial loc

Answer 14

in peretele Ad, in apropierea orificiului de varsare al VCs (venei cave superioare)

Question 15

nodul sinoatrial rol

Answer 15

descarca 70-80 de impulsuri el pe min, ce vor fi urmate de 70-80 contractii mecanice

+ cand inima functioneaz sub coord lui, fct in ritm SINUSAL - normal

Question 16

n. atrioventricular loc

Answer 16

in septul inter-atrial , aproape de cel interventriculare

Question 17

n. atrioventricular rol

Answer 17

poate descarca 40 de impulsuri el/min
+ 40 de contractii mecanice
daca inima fct in ritm NODAL sau JONCTIONAL

Question 18

Fasciculul His + reteaua Purkinje rol

Answer 18

25 impulsuri el/min
daca inima fct in ritm IDOVENTRICULOAR

Question 19

Tes mec al inimii =
consta in

Answer 19

ciclul cardiac format dintr-o succesiune sistola + diastola

Question 20

ciclul cardiac formula

Answer 20

1 C.C. = S + D

Question 21

durata 1 C.C.

Answer 21

= 0,8 sec

Question 22

zgomotele inimii

Answer 22

Z1= sistolic= inchid valvelor atrio-ventriculare
Z2= inchid valv semilunare

Question 23

Z1 - ce tip de zgomot

Answer 23

lung, tonalitate josa (lub)

Question 24

Z2 -ce tip de zgomot

Answer 24

scurt, ascutit (dub)

Question 25

Param fct ai inimii

Answer 25

-puls arterial -TA -tens art 120/80 - 130/90 mm col Hq -frecventa: Fc=70-80 b/min -debitul sistolic=volum batai = 70 ml debitul cardiac=75*70=5,25l/min

Question 26

bola acu tens mica

Answer 26

hipotensiune hTA

Question 27

cu tens mare

Answer 27

hipertensiune HTA
