Arteries have thick muscular walls to withstand high blood pressure exerted by the pumping action of the heart.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Circulatory System - Comparative and Evolutionary Aspects
The pulmonary arteries carry deoxygenated blood from the heart to the lungs.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Circulatory System - Comparative and Evolutionary Aspects
Pulmonary veins carry oxygenated blood from the lungs to the heart, so not all veins carry deoxygenated blood.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Circulatory System - Comparative and Evolutionary Aspects
The pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation ECG and Blood Vessels
The QRS complex represents ventricular depolarization, leading to ventricular contraction.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation ECG and Blood Vessels
The vena cava carries deoxygenated blood from the body back to the right atrium of the heart.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation ECG and Blood Vessels
The left ventricle pumps blood into the aorta, not the pulmonary artery. The right ventricle pumps blood into the pulmonary artery.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
Not all arteries carry oxygenated blood. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
The pulmonary valve prevents backflow of blood into the right ventricle after it enters the pulmonary artery.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
The duration of one complete cardiac cycle is about 0.8 seconds in a healthy adult.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
