This is the correct path of an electrical excitation from the pacemaker to a cardiocyte in the left ventricle (LV).
A. sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV
B. atrioventricular (AV) node → sinoatrial (SA) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV
C. sinoatrial (SA) node → atrioventricular (AV) bundle → atrioventricular (AV) node → Purkinje fibers → cardiocyte in LV
D. atrioventricular (AV) node → Purkinje fibers → atrioventricular (AV) bundle → sinoatrial (SA) node → cardiocyte in LV
E. sinoatrial (SA) node → atrioventricular (AV) node → Purkinje fibers → atrioventricular (AV) bundle → cardiocyte in LV
Answer:
The correct answer is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV (A.)
Explanation:
The electrical impulse conduction system of the heart refers to the pathways through which electrical signals pass, to cause excitation of specific paths of the heart, leading to depolarization, which in turn leads to contraction and relaxation of the heart. The correct excitation pathway is as follows:
1. Normal excitation originates in the sinoatrial (SA) node, from which depolarization spreads throughout the atria, causing impulses (excitation) to spread from the SA node to the atria. It is believed that this depolarization spreads to the atrial cells through adjacent myocardial cells and myofibrils.
2. Next, the depolarization from the atria reaches the atrioventricular (AV) node, causing excitation of the AV node. The AV node is located on the floor of the right ventricle, close to the interventricular septum. The excitation leaves this site by two pathways; the fast and slow pathways which vary based on the time of transmission of impulses to the next phase.
3. Next, from the AV node, the excitation is passed to the two branches of the bundle of His, which form a network of fibers known as purkinje fibers, from where excitation passes to the apical region of the left and right ventricles causing depolarization of the ventricular myocardium.
Attached to this answer is a picture to show what the pathway looks like.
The correct path of an electrical excitation from the pacemaker to a cardiomyocyte is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Subendothelial conducting network → cardiomyocyte in LV.
The heart is a cone-shaped hollow muscular organ that possesses the property of generating its own electrical impulses or excitations.
It is divided into four(4) chambers namely the right ventricle, left ventricle, right atrium and left atrium.
The correct path of an electrical excitation is from:
The pacemaker: This is also called the sinoatrial (SA) node. It generates the electrical excitations.Atrioventricular (AV) node: The electrical excitation initiated by SA node is then transmitted to AV node. This transmits the signal from atria to ventricles.Atrioventricular (AV) bundle: These are specialised fibres that originate from the AV node. They are the bundle that divides to form the right and left bundle branches.Subendothelial conducting network: This is also called the Purkinje fibres which is formed within the ventricular myocardium.Cardiomyocyte of the left ventricle: The cardiomyocytes are set of cells that generates contractile force in the heart. These are located at the left ventricle.Therefore, the correct path of an electrical excitation from the pacemaker to a cardiomyocyte is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Subendothelial conducting network → cardiomyocyte in LV.

(MI) Myocardial Infarction
Explanation:
Myocardial infarction (MI, heart attack) is produced when the velocity of blood flow decreases in the heart, which can lead to injury of the heart muscle. The symptoms of a heart attack include pressure, tightness or pain in the chest, shortness of breath, anxiety, nausea and vomiting. MI can be prevented by healthy life habits such as plenty of sleep, healthy food habits, and regular exercise. A heart attack should be treated immediately by angioplasty, which is a medical procedure to unblock the arteries that transport blood to the heart.

Body weight, body fat, inflammatory proteins, and blood pressure drop when people cut back on their usual energy intake by ____ percent.
Answers
Answer:
10-20%
Explanation:
Body weight, body fat, inflammatory proteins, and blood pressure drop when people cut back on their usual energy intake by 10 to 20 percent.
This is because excess energy intake results to them being stored in the body for future purposes. They are usually stored as fats which clogs the arteries and results in the heart using more pressure in pumping blood to parts of the body.

According to the escience lab manual for lab 1, experiment 3, you need to prepare a 47 mL of a 24% soda/syrup prescription. To do this, you can use the 80% syrup solution and the 10% soda solution that you have in stock. How many mLs of soda solution do you need to create this final solution?
Answers
Answer:
33 mL
Explanation:
It is important to recognize that the total amount of pure syrup remains constant:
Total syrup in the stock solution = total syrup in dilute solution
Thus, we can use the dilution formula
V₁c₁ = V₂ c₂
Data:
V₁ = ?; c₁ = 80 %
V₂ = 47 mL; c₂ = 24 %
Calculations:
1. The volume of stock syrup
[tex]\begin{array}{rcl}V_{1}c_{1} & = & V_{2}c_{2}\\V_{1}\times80 \, \% & = & \text{47 mL}\times 24 \, \%\\80V_{1} & = & \text{1130 mL}\\V_{2}&=& \dfrac{\text{1130 mL}}{80}\\\\&=&\text{14 mL}\\\end{array}\\\text{You need $\textbf{14 mL}$ of stock syrup.}[/tex]
2. The volume of soda solution
Total volume of dilute solution = 47 mL
The volume of stock syrup = 14
Volume of soda solution = 33 mL
You need 33 mL of soda solution.

For how long should most adults in moderately good physical condition and with healthy lungs be able to hold their breath
Answers
Answer:
30 seconds and up to 2 minutes
Explanation:
Most adults should be able to hold their breath for between 30 and 1 minute if they are in relatively excellent physical condition and have healthy lungs. However, this can change depending on things like age, fitness level and general health.
What is Health?The concept of health is comprehensive and includes a state of mind, body and social relations of an individual. Physical fitness is the state of a person's body and their ability to engage in physical activity without experiencing excessive fatigue or physical restrictions. Regular exercise, proper diet, getting enough sleep and avoiding bad habits like smoking and excessive drinking are all necessary to maintain excellent physical health.
Maintaining healthy lungs is important for maintaining physical health in terms of lung health. The lungs are affected by many variables including smoking, air pollution and respiratory diseases. They are in charge of supplying oxygen to the body and eliminating carbon dioxide. Regular exercise can help increase lung capacity and function.
Therefore, most adults should be able to hold their breath for between 30 and 1 minute if they are in relatively excellent physical condition and have healthy lungs.

A child is to undergo a tympanostomy tube placement in a freestanding outpatient surgery center. What is the major disadvantage associated with this location? Increased risk for infection
Answers
Answer: The options are not complete, they are;
A) Risk for infection
B) Increased healthcare costs
C) Need to be transferred if overnight stay is required
D) Increased disruption of family functioning.
The correct answer to the question is option C
NEED TO BE TRANSFERED IF OVERNIGHT STAY IS REQUIRED.
Explanation: tympanostomy tube placement is a surgical procedure that done by inserting a grommet or a tympanostomy( a tube of less than 2mm in diameter) into the ear drum of a patient/client.the indication or purpose is to maintain an aerated middle ear over a prolonged period of time,this will as well prevent fluid from accumulating in the middle ear.
Incase of complications of tympanostomy tube placement like bleeding or persistent draining of fluid, scarring and weakening of the ear drum or the tube falling out too early, the child might need to be kept in the hospital facility for proper monitoring and this will necessitate the transfer of the child to another hospital facility for good and proper monitoring and management since the tube placement was done in a freestanding out-patient surgery center where there is no provision for admission of patient or overnight stay.
