The conduction system of the heart consists primarily of specialized cardiac muscle cells known as pacemaker cells and conduction fibers. Pacemaker cells, such as those found in the sinoatrial (SA) node, initiate electrical impulses that regulate the heartbeat. Conduction fibers, including the atrioventricular (AV) node, bundle of His, and Purkinje fibers, transmit these impulses throughout the heart, ensuring coordinated contractions. Together, these cells facilitate the rhythmic and efficient pumping of blood.

What are the two types of cells in softwood?
The two types of cells in softwood are tracheids and parenchyma cells. Tracheids are responsible for water conduction and support, while parenchyma cells are involved in storage and other metabolic functions.
Which organ system produces two cells?
The reproductive system is the organ system that produces two cells: the egg (ova) in females and sperm in males. These cells are involved in the process of fertilization to generate a new organism.
What division of the nervous system has 2 motor nerve cells?
The division of the nervous system that has two motor nerve cells is the autonomic nervous system (ANS). The ANS is responsible for regulating involuntary bodily functions and consists of two main branches: the sympathetic and parasympathetic nervous systems. Each branch utilizes a two-neuron pathway, consisting of a preganglionic neuron and a postganglionic neuron, to transmit motor signals to target organs.
What are the characteristics of each of the two arms of the adaptive defense system?
The adaptive defense system consists of two main arms: humoral immunity and cell-mediated immunity. Humoral immunity is characterized by the production of antibodies by B cells, which target and neutralize pathogens in the body fluids. In contrast, cell-mediated immunity involves T cells that directly attack infected or cancerous cells and orchestrate the immune response. Together, these two arms provide a tailored defense against specific pathogens and ensure long-lasting immunity through memory cells.
Nervous system what are the two nervous systems?
the central nervous system which consists of the brain and spinal cord. the peripheral nervous system which consists of nerves and ganglia (collection of nerve cell bodies outside the central nervous system). AND -peripheral. -central.
What is the Epithelial tissue made up of?
It consists of two cells. The epidermal cells and the guard cells.
What are the two types of cells in softwood?
The two types of cells in softwood are tracheids and parenchyma cells. Tracheids are responsible for water conduction and support, while parenchyma cells are involved in storage and other metabolic functions.
Where does nerve conduction deafness occur?
Nerve conduction deafness is one of the two types of deafness that can happen. It occurs when there is a break in communication between the nerve cells and the inner ear.
What two problems did the development of a vascular system solve for land plants?
Conduction and firmness
What is the respiratory system structures?
it consists of two parts
The binary system used by a digital computer consists of?
it consists of two numbers : 0 and 1
Definition of system surroundings?
a system consists of two kinds:the endothermic and exothermic reaction.
Is a conduction through the autonomic efferent chain faster than conduction the somatic motor system?
Yes, conduction through the autonomic efferent chain is generally slower than conduction through the somatic motor system. This is because the autonomic nervous system involves two neurons in the pathway (preganglionic and postganglionic), which introduces a delay in signal transmission compared to the direct pathway in the somatic motor system with only one neuron.
Which organ system produces two cells?
The reproductive system is the organ system that produces two cells: the egg (ova) in females and sperm in males. These cells are involved in the process of fertilization to generate a new organism.
What two components of the conduction system constitute the only electrical link between the atria and the ventricles?
The atrioventricular node and the bundle of HIS are the electrical conduction link between the atria and the ventricles.
What are the components of the cardiac conduction system?
The conduction starts at the pacemaker region called the Sinoatrial Node (SA node) which is just under where the superior vena cava enters the right atrium. From here the conduction passes to the Atrioventricular Node (AV node) which is just ot the right of the septum. From here the stimulation is passed through the Bundle of His which carries the conduction to the septum where two Bundle Branches pick it up. These branches carry the conduction to the base of the septum where they sperate into the Purkinje Fibres. These fibres carry the conduction all around the heart.
