Cardiac Conduction System (CCS)
There are specialized areas of cardiac muscle tissue in the heart that beat on their own.
These specialized areas together coordinate the events of the cardiac cycle, which makes the heart an effective pump.
Components of CCS:
1. Sinoatrial Node (S-A Node) located in right uppermost atrial wall and the primary pacemaker(rhythmically and repeatedly [60-100 per minute] initiates cardiac impulses)2. Atrioventricular Node (A-V Node): located in interatrial septum;
serves as a delay signal that allows for ventricular filling. A back up pace maker.3. Atrioventricular (AV) Bundle (Bundle of His): only electrical connection between the atria and ventricles; located in the superior interventricular septum;4. Right and left bundle branches head downward through interventricular septum toward apex, and impulse finally reaches.5. Purkinje Fibers (Conduction Myofibers) large diameter conduction myofibers; located within the papillary muscles of the ventricles and conduct the impulse into the mass of ventricular muscle tissue.
What else can I help you with?
What does a defibrilator do?
It produces an electrical impulse used to restart the hearts' rhythm after a cardiac arrest.
Why do we use sheep's heart for the examination?
As it is similar in structure to human hearts and they are readily available whereas most humans are buried with their hearts.
What kind of hearts do birds have?
Birds have four-chambered hearts that are similar in structure to mammalian hearts. Their hearts are efficient at pumping oxygenated blood through their bodies to support their high metabolic rates and active lifestyles.
Who creates and produces Kingdom Hearts?
mostly square-enix, if you're asking about the director than he is tetsuya nomura
Will there be a Kingdom Hearts that takes place where Kingdom Hearts 2 leaves off?
well in the cut scene in final mix with aqua and friends the bald dude does shoot sum s*** into the sky and it produces kingdom hearts so ya id say it will have it in there
What body structure causes blood circulation in the worm?
They have hearts with blood vessels that pump the blood to the rest of their body
Do bleeding hearts produce fruit?
Yes, bleeding hearts do produce fruit. The fruit is a small, round structure that contains seeds. However, the fruit is not considered decorative and is generally not a significant ornamental feature of the plant.
What does the heart do in the worm?
It has aortic arches which are objects similar to hearts. There are four aortic arches in a single worm.
Similarities and differences between chicken heart and mammilian heart?
Both chicken hearts and mammalian hearts serve the primary function of pumping blood throughout the body, and both have four chambers—two atria and two ventricles, although the structure and arrangement can vary. A key difference lies in their physiology: chicken hearts are more efficient for their high metabolic demands during flight, while mammalian hearts are adapted for a wide range of activities, including sustained endurance. Additionally, chicken hearts have a more compact structure, while mammalian hearts exhibit a greater degree of specialization in their chambers and valves. Lastly, the regulation of heart rate and contraction can differ due to variations in hormonal and neural controls.
What produces pressure?
Systolic pressure is the maximum pressure during the hearts pumping cycle. It occurs during left ventricle contraction or sqeezing which forces the blood around the arteries
What is the difference between a chicken and pig heart?
The main difference between a chicken and pig heart is their size. Pig hearts are larger and have a more complex structure than chicken hearts. Additionally, the muscle fibers and overall composition of the two hearts may differ slightly.
What produces systolic pressure?
Systolic pressure is the maximum pressure during the hearts pumping cycle. It occurs during left ventricle contraction or sqeezing which forces the blood around the arteries
