We can also maintain a balanced intake of food that is low in fat and do regular exercises.]]> 2021-07-09 07:05:13 UTC https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643065178 Health issues related to blood clotting https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643069657 2021-07-09 07:09:43 UTC https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643069657 https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643071601 2021-07-09 07:11:26 UTC https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643071601 K4 maemaechi https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643071772 Athirah

Explain this.

Q2 Differentiate between the impact from impulses
generated by the sinoatrial node and the
atrioventricular node.

Q3 State the impulse pathway from when it was
triggered to when it produces a pumping action
in the heart.

Q4 Muscular dystrophy causes weakness and loss of function in muscles. State how this disease affects the blood circulation in patients.

Q5 Heartbeat can be detected using a stethoscope.
Why is the sound more easily heard near the chest than in the arm?

Q6 State the two groups of specialised cells that are involved in producing the pumping force.]]> 2021-07-09 07:57:30 UTC https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643112975 Answer https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643114027 A1 Can produce own impulse for muscle contraction and relaxation without stimulus from nervous system.

A2 Sinoatrial node impulse causes contraction to both atria whereas atrioventricular node impulse causes contraction to both ventricles.

A3 Right atrial upper wall → whole atrial wall → Bundle of His muscle fibres →
Purkinje fibres → whole ventricular wall

A4 Shrinking of skeletal muscles weakens muscle contractions. Less / no pressure on vein. Blood pressure in vein will be reduced. Difficulty in transporting blood to heart.

A5 Heart is in thoracic cavity of chest.Pulse is stronger in chest than arm

A6 Sinoatrial node (SA) and Atrioventricular node (AV)]]> 2021-07-09 07:58:52 UTC https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643114027 https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643114934 The question]]> 2021-07-09 08:00:10 UTC https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643114934 https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643115628 The answer]]> 2021-07-09 08:01:20 UTC https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643115628 NOTES 10.6 https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643127557 2021-07-09 08:16:45 UTC https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643127557 NOTES 10.8 https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643129354 2021-07-09 08:19:09 UTC https://padlet.com/g18140922/amg9zwv52yyul6b/wish/1643129354
