Answer:
The correct answer will be option-A
Explanation:
Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.
The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.
As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.
Thus, option-true is the correct answer.
Answer:
The correct answer is D. resting phase
Explanation:
Diastole is the resting phase when relaxation of heart muscles takes after contraction(systole). In this phase blood from veins and coronary sinus comes into the auricles and ventricles because of the pressure in the heart is less than veins and opening of A-V valve.
When both auricles and ventricles are relaxed it is called joint diastole. Joint diastole is called complete cardiac diastole and is 0.4 sec long. After the joint diastole auricular systole occurs in which auricles are contracted and ventricles are still relaxed called ventricular diastole.
After the end of auricular systole ventricles contraction starts and auricular relaxation occurs called auricular diastole.
Answer and Explanation:
the pectoralis minor is the muscle medial to deltoid muscle the shape of this pectoralis minor is fan shaped muscle of shoulder girdle it originates from third to fifth ribs and insert in coracoid process of the scapula. its lateral part originates from dedial part of deltoid muscle. so we can conclude that pectoralis minor is the medial of deltoid muscle
Answer:
Very low density lipoprotein (VLDL) is a particle containing triglycerides and cholesterol and protein that is made by the liver. VLDL goes up with diets that contain a lot of fat, sugar, or alcohol. It can also be high in conditions such as diabetes and kidney disease.
