1. Analysis of urine helps in clinical diagnosis of few genetic disorders also.

2. Muscles, essential for locomotion and other bodily movements, come in three main types: skeletal, visceral, and cardiac.

3. A chemosensitive area is situated in pons, adjacent to the respiratory rhythm centre, which is highly sensitive to O₂ and hydrogen ions.

4. The spaces between cells in the tissues contain a fluid derived from blood called tissue fluid.

5. The contraction of external intercostal muscles lifts up the ribs and the sternum, causing a decrease in the volume of the pulmonary chamber in the dorso-ventral axis.

6. Double walled cup-like structure called Bowman’s capsule is a part of renal tubule.

7. Tarsals are ankle bones.

8. PCT also helps to maintain the pH and ionic balance of the body fluids by selective secretion of hydrogen ions and ammonia into the filtrate and by secretion of HCO3– from it.

9. In a unipolar neuron, transmission of impulses is unidirectional.

10. Before the atrial contraction 30 per cent of blood drained by the atria into the ventricle.

11. A voluntary movement which causes the animal to change its place, is called locomotion.

12. Fascicles consists of muscle bundle.

13. Pectoral girdle is formed of one pairs of bones.

14. In a sarcomere, between consecutive actin myosin overlaps thin filaments are there.

15. Expiration is a passive and prolonged process when compared to inspiration.

16. PCT also helps to maintain the pH and ionic balance of the body fluids by selective absorption of hydrogen ions and ammonia into the filtrate and by secretion of HCO3– from it.

17. The most abundant muscle type in a human body is skeletal muscle.

18. Relaxation of the diaphragm decreases the thoracic volume indirectly.

19. In Henle’s loop, as medullary fluid passes downward, it gets concentrated due to passage of electrolytes to the filtrate.

20. Haemoglobin doesn’t bind to oxygen; it’s just floating around aimlessly.

21. The process of secreting ammonia is Ammonotelism.

22. The sino-atrial node (SAN) is present in the right upper corner of the right atrium.

23. Movement of cilia, flagella, and pseudopodia can be seen in humans.

24. Inside the kidney, there are two zones, an inner cortex, and an outer medulla.

25. Lymph types are not categorised to A, B, AB, and O.

26. Human neural system consists of two parts : (i) central neural system (CNS) and (ii) the peripheral neural system.

27. The electrical activity of the heart can be recorded from the body surface by using an electrocardiograph, and the recording is called electrocardiogram (ECG) which is of clinical importance.

28. Electric current could flow directly from one neuron to another neuron.

29. Partial pressure of CO₂ of alveoli is the same as partial pressure of oxygen in deoxygenated blood.

30. Muscle fibres and nerve fibres are different types of cells.

31. The action potential causes the atria and then the ventricles to undergo contraction (systole) followed by their relaxation (diastole).

32. Relaxation of the diaphragm increases the thoracic volume.

33. Between consecutive ‘A’ bands one ‘H zone’ is there at the middle.

34. Lymph is not a fluid used for transport; it’s a solid tissue found in the body.

35. In the tissues where pCO₂ is high, oxygen gets bound to blood whereas in the alveoli where pCO₂ is low and pO₂ is high, it gets removed from the blood.

36. The role of oxygen in the regulation of respiratory rhythm is quite significant.

37. Between consecutive ‘I’ bands, thin filaments are present.

38. A cup shaped bone called patella cover the knee dorsally.

39. Juxta medullary nephrons could reabsorb more water.

40. Another blood grouping is also done based on the presence or absence of another antigen called Rhesus factor (Rh) on the surface of RBCs.

41. The CNS comprises the brain and the spiral cord.

42. Receiving both water and electrolytes from the filtrate raises the osmolarity of medullary fluid as it descends deeper.

43. Each minute a healthy adult produces 1 ml of urine (on average).

44. Pectoral girdle is formed of four bones.

45. The cerebellum integrates information received from the semicircular canals of the ear and the auditory system.

46. From the apex of the heart AV node is nearer than the SA node.

47. The somatic neural system relays impulses from the PNS to skeletal muscles.

48. Three types of muscles are present in our body.

49. In Henle’s loop, as medullary fluid passes downward, it gets concentrated due to passage of water to the filtrate.

50. Glomerulus is not the part of renal tubule.
