Preparing for NEET PG requires a strong foundation in basic sciences, and <\/span>Physiology<\/b> is one of the most important subjects. Not only does it form the base for clinical subjects, but it also contributes a significant number of questions in the exam. If you are targeting a high rank, focusing on the important Physiology questions for NEET PG 2026<\/strong><\/a> can give you a strategic advantage.<\/span><\/p>\n

In this blog, we will cover high-yield topics, covered questions, Previous year question and frequently asked questions, to master Physiology effectively.<\/span><\/p>\n

Q1. A 60-year-old male presents with dyspnea and pedal oedema. Echocardiography shows decreased ejection fraction. Which of the following is the most sensitive indicator of left ventricular function?<\/b><\/p>\n

A. Stroke volume<\/span>
\n<\/span>B. Cardiac output<\/span>
\n<\/span>C. Ejection fraction<\/span>
\n<\/span>D. End-diastolic volume<\/span><\/p>\n

Answer: C. Ejection fraction<\/b><\/p>\n

Ejection fraction (EF) reflects the percentage of blood ejected from the left ventricle during systole. It is the <\/span>best indicator of LV systolic function<\/b>, commonly reduced in heart failure.<\/span><\/p>\n

Q2. A patient has increased preload. According to Frank-Starling’s law, what will happen?<\/b><\/p>\n

A. Decrease in stroke volume<\/span>
\n<\/span>B. Increase in stroke volume<\/span>
\n<\/span>C. No change<\/span>
\n<\/span>D. Decrease in contractility<\/span><\/p>\n

Answer: B. Increase in stroke volume<\/b><\/p>\n

Frank-Starling mechanism states that <\/span>increased ventricular filling (preload)<\/b> leads to increased myocardial stretch \u2192 stronger contraction \u2192 increased stroke volume.<\/span><\/p>\n

 <\/p>\n

Q3. A patient with hypertension is given a drug that decreases peripheral resistance. Which parameter will increase immediately?<\/b><\/p>\n

A. Afterload<\/span>
\n<\/span>B. Stroke volume<\/span>
\n<\/span>C. Heart rate<\/span>
\n<\/span>D. Venous return<\/span><\/p>\n

Answer: B. Stroke volume<\/b><\/p>\n

Decreased peripheral resistance \u2192 decreased afterload \u2192 easier ejection \u2192 increased stroke volume.\u00a0<\/span><\/p>\n

 <\/p>\n

Q4. A patient at high altitude develops breathlessness. Which of the following shifts the oxygen dissociation curve to the right?<\/b><\/p>\n

A. Decreased 2,3-BPG<\/span>
\n<\/span>B. Decreased CO\u2082<\/span>
\n<\/span>C. Increased temperature<\/span>
\n<\/span>D. Increased pH<\/span><\/p>\n

Answer: C. Increased temperature<\/b><\/p>\n

Right shift occurs with:<\/span><\/p>\n
