20. Hemoglobin
Hemoglobin is a protein present in red blood cells that carries oxygen from the lungs to body tissues and carbon dioxide back to the lungs.
21. Cardiac Output
Cardiac Output is the amount of blood pumped by the heart in one minute.
Formula:
Cardiac Output = Stroke Volume × Heart Rate
22. Stroke Volume
Stroke Volume is the amount of blood pumped out by the left ventricle during one heartbeat.
23. Oxygen Debt
Oxygen debt is the extra oxygen required after strenuous exercise to restore the body to its normal state.
24. BMI (Body Mass Index)
BMI is used to determine whether a person has a healthy body weight.
Formula:
BMI = Weight (kg) / Height² (m²)
25. BMR (Basal Metabolic Rate)
BMR is the minimum amount of energy required by the body to perform vital functions while at complete rest.
26. Vital Capacity
Vital Capacity is the maximum amount of air that can be exhaled after taking the deepest possible breath.
27. Endocrine Glands
Endocrine glands are ductless glands that secrete hormones directly into the bloodstream. These hormones regulate growth, metabolism, reproduction, and body functions. Major endocrine glands include the pituitary, thyroid, parathyroid, adrenal glands, pancreas, testes, and ovaries.
28. Digestive System Organs
The digestive system consists of organs that help digest food and absorb nutrients. The main organs are:
- Mouth
- Pharynx
- Oesophagus
- Stomach
- Small Intestine
- Large Intestine
- Rectum
- Anus
- Liver
- Pancreas
- Gall Bladder
29. Iodine
Iodine is an essential mineral required for the production of thyroid hormones. It helps regulate metabolism and growth. Deficiency of iodine can cause goitre.
Sources: Iodized salt, seafood, milk.
30. Sodium
Sodium helps maintain fluid balance, nerve function, and muscle contraction. It is an important electrolyte in the body.
Sources: Common salt, milk, eggs, vegetables.
31. Iron
Iron is essential for the formation of hemoglobin in red blood cells. It helps transport oxygen throughout the body.
Sources: Green leafy vegetables, liver, eggs, pulses.
32. Phosphorus
Phosphorus helps in the formation of bones and teeth. It also plays an important role in energy production.
Sources: Milk, fish, eggs, meat.
33. Calcium
Calcium is necessary for strong bones and teeth. It also helps in muscle contraction and blood clotting.
Sources: Milk, cheese, curd, green vegetables.
34. Minerals
Minerals are inorganic nutrients required for proper body functioning. They help in growth, bone formation, blood production, and maintaining health.
Examples: Calcium, Iron, Phosphorus, Sodium, Iodine.
35. Vitamins
Vitamins are protective nutrients that regulate body processes and prevent diseases. They are essential for growth and health.
Examples: Vitamin A, B, C, D, E, and K.
36. Fats
Fats are concentrated sources of energy. They protect internal organs and help absorb fat-soluble vitamins.
Sources: Butter, ghee, oils, nuts.
37. Proteins
Proteins are body-building nutrients. They help in growth, tissue repair, and muscle development.

41. Small Intestine
The small intestine is the longest part of the digestive system. Most digestion and absorption of nutrients take place here.
42. Large Intestine
The large intestine absorbs water and salts from undigested food. It forms and stores feces before elimination.
43. Gall Bladder
The gall bladder is a small sac located below the liver. It stores bile juice and releases it into the small intestine for fat digestion.
