  • (a) Diabetes insipidus
  • (b) Myasthenia gravis
  • (c) Gout
  • (d) Osteoporosis

Answer: (a) Diabetes insipidus


Q3. Which of the following enzymes is involved in blood coagulation?


  • (a) Renin
  • (b) Thrombin
  • (c) Pepsin
  • (d) Amylase

Answer: (b) Thrombin


Q4. Identify the correct sequence of events in muscle contraction:


  • (a) Binding of calcium ions – ATP hydrolysis – Cross bridge formation – Power stroke
  • (b) ATP hydrolysis – Cross bridge formation – Binding of calcium ions – Power stroke
  • (c) Cross bridge formation – Binding of calcium ions – ATP hydrolysis – Power stroke
  • (d) Power stroke – Cross bridge formation – Binding of calcium ions – ATP hydrolysis

Answer: (a) Binding of calcium ions – ATP hydrolysis – Cross bridge formation – Power stroke


Q5. Which blood group can accept blood from any group (universal recipient)?


  • (a) AB
  • (b) A
  • (c) B
  • (d) O

Answer: (a) AB


2. Very Short Answer (VSA).


Q1. Name the respiratory pigment present in human blood.


Answer: Haemoglobin is the respiratory pigment in human blood. It transports oxygen from the lungs to body tissues and helps in carbon dioxide transport as well.


Q2. What is double circulation?


Answer: Double circulation is the flow of blood twice through the heart – once as deoxygenated blood to the lungs and then as oxygenated blood to the rest of the body.


Q3. Which cells initiate and regulate the heartbeat?


Answer: The sinoatrial node (SA node) initiates and regulates the heartbeat, acting as the pacemaker of the heart.


Q4. Which hormone increases water reabsorption in kidneys?


Answer: Antidiuretic hormone (ADH), also known as vasopressin, increases water reabsorption in kidney tubules.


Q5. Name a disorder caused by the hypersecretion of growth hormone in adults.


Answer: Acromegaly is caused by the hypersecretion of growth hormone in adults, leading to abnormal bone and tissue growth.


3. Short Answer Questions.


Q1. Briefly describe the process of urine formation in humans.


Answer: Urine formation in humans consists of three steps: glomerular filtration, tubular reabsorption, and tubular secretion. Blood is filtered in the glomerulus. Essential substances and water are reabsorbed in the tubules, while waste products and excess ions are secreted into the filtrate to form urine.


Q2. Differentiate between asthma and emphysema.


Answer: Asthma is a respiratory disorder characterized by inflammation and narrowing of the airways, leading to breathlessness. Emphysema involves damage to the alveolar walls, resulting in decreased surface area for gas exchange and reduced oxygen supply to the body.


Q3. Explain the role of sodium ions in the generation of nerve impulses.


Answer: Sodium ions enter the neuron during the depolarization phase, causing the membrane potential to rise. This rapid influx generates the action potential, which transmits nerve impulses along the neuron.


Q4. List two functions of lymph in the human body.


Answer: Lymph helps maintain fluid balance by returning excess interstitial fluid to the bloodstream. It also plays a vital role in immune defense by transporting lymphocytes and filtering pathogens through lymph nodes.


Q5. Write the functions of the hypothalamus.


Answer: The hypothalamus regulates body temperature, hunger, and thirst. It also controls the pituitary gland, thus influencing hormone release, stress response, and various homeostatic processes in the human body.


4. True or False Questions.


Q1. Erythrocytes contain nuclei in human adults.


Answer: False


Q2. Insulin is secreted by the alpha-cells of the pancreas.


Answer: False


Q3. The pulmonary artery carries deoxygenated blood.


Answer: True


Q4. Myasthenia gravis is a muscular disorder.


Answer: True


Q5. Platelets are essential for blood clotting.


Answer: True


3. Fill in the Blanks Questions.


Q1. The structural and functional unit of the kidney is ______.


Answer: nephron


Q2. ______ are the contractile proteins present in skeletal muscle.


Answer: Actin and myosin


Q3. The ______ gland secretes thyroxine.


Answer: thyroid


Q4. Exchange of gases in the lungs occurs in ______.


Answer: alveoli


Q5. ______ is a disorder characterized by high blood pressure.


Answer: Hypertension
