Questions and Solutions

Question 1

Define anatomy.
Solution: Anatomy is the scientific discipline concerned with the study of the structure of the human body and the relationships between its parts. The term 'anatomy' originates from Greek words: 'ana' meaning 'apart' and 'tomy' meaning 'to cut'. Historically, anatomical knowledge was primarily gained through the process of dissection.

Question 2

Define physiology.
Solution: Physiology is the branch of biology that focuses on the study of the functions and mechanisms which work within a living system. It explores how the organs, cells, and chemical substances work together to form a living organism. In essence, it is the science of the mechanical, physical, and biochemical functions of the body's organs and constituent cells.

Question 3

Name any four physiological systems of human body.
Solution: The human body is composed of several complex physiological systems that work in coordination. Four major physiological systems are:
  1. Skeletal System: Provides support, structure, and protection.
  2. Muscular System: Enables movement and generates heat.
  3. Digestive System: Breaks down food and absorbs nutrients.
  4. Respiratory System: Facilitates gas exchange (oxygen and carbon dioxide).

Question 4

Define skeletal system.
Solution: The skeletal system forms the body's internal framework, providing structural support and shape. It is composed of all the bones in the body, which are interconnected to form a rigid yet dynamic structure essential for protection of vital organs and facilitating movement.

Question 5

What do you understand by joint?
Solution: A joint is defined as the point or area in the body where two or more bones meet or articulate. These junctions are crucial for movement and stability. Joints can be classified based on their structure and the degree of movement they allow, ranging from fixed (immovable) joints to freely movable joints.

Question 6

Which is the longest and the smallest bone in human body?
Solution: The longest bone in the human body is the Femur, located in the thigh. The smallest bone in the human body is the Stapes, which is one of the tiny bones found in the middle ear.

Question 7

What is a muscle?
Solution: A muscle is a type of body tissue that has the unique ability to contract and relax, thereby producing movement. Muscles are composed of specialized fibers that generate force when stimulated, enabling a wide range of bodily actions, from locomotion to internal organ function.

Question 8

Enlist types of muscles.
Solution: Muscles in the human body can be broadly classified into three main types based on their structure, function, and control:
  1. Voluntary/Skeletal/Striated Muscle: These muscles are under conscious control and are attached to bones, enabling movement. They appear striped or striated under a microscope.
  2. Involuntary or Smooth or Spindle Muscle: These muscles operate automatically, without conscious thought, and are found in the walls of internal organs like the digestive tract and blood vessels.
  3. Cardiac Muscle: This specialized type of muscle is found exclusively in the heart wall. It is involuntary and responsible for pumping blood throughout the body.

Question 9

Which is the hardest working muscle in our body?
Solution: The Cardiac muscle is considered the hardest working muscle in our body. It continuously contracts and relaxes throughout our lives, without rest, to pump blood and sustain circulation.

Question 10

Which is the strongest muscle in our body?
Solution: The Jaw muscle (specifically, the masseter muscle) is generally considered the strongest muscle in the human body. This is based on its ability to exert the greatest force relative to its size, allowing for powerful chewing.

Question 11

How many bones are there in a Child and an Adult?
Solution: The number of bones changes from birth to adulthood. A newborn baby typically has around 270-300 bones, which fuse together as the child grows. An adult human skeleton consists of 206 bones. The source mentions 213 bones for a child, which is a common approximation for younger children before significant fusion occurs.

Question 12

What is tidal volume?
Solution: Tidal volume refers to the normal volume of air that is inhaled or exhaled during a single, quiet breath. It represents the amount of air that moves in and out of the lungs during normal respiration without any extra effort.

Question 13

What is vital capacity?
Solution: Vital capacity is a measure of lung function that represents the maximum amount of air a person can forcibly exhale after taking the deepest possible inhalation. It is a key indicator of respiratory health and lung efficiency. The typical vital capacity is approximately 4800 cubic centimeters (cc) for males and about 3100 cc for females.

Question 14

What is heart rate?
Solution: Heart rate is defined as the number of times the heart beats or contracts in one minute. It is a vital sign that reflects the body's circulatory function. Under normal resting conditions, the average heart rate for an adult is approximately 72 beats per minute.

Common mistakes

  • Confusing anatomy (structure) with physiology (function).
  • Incorrectly identifying the longest or smallest bone.
  • Difficulty in distinguishing between voluntary and involuntary muscles.
  • Misunderstanding the definitions of physiological terms like tidal volume and vital capacity.

Revision tips

  • Create flashcards for key definitions like anatomy, physiology, and muscle types.
  • Draw diagrams of the skeletal system and label major bones.
  • Practice reciting the names of physiological systems and their basic functions.
  • Use the provided definitions to explain concepts to a study partner.
  • Focus on understanding the difference between structure (anatomy) and function (physiology).

Frequently asked questions

What is the difference between anatomy and physiology?

Anatomy is the study of the structure of the human body, while physiology is the study of the functions of the human body.

Can you name the four physiological systems covered in this chapter?

Yes, the chapter mentions the Skeletal System, Muscular System, Digestive System, and Respiratory System.

What are the longest and smallest bones in the human body?

The longest bone is the Femur (thigh bone), and the smallest bone is the Stapes (ear bone).

What is the significance of studying anatomy and physiology in Physical Education?

Understanding anatomy and physiology is crucial for comprehending how the body works during physical activity, injury prevention, and performance enhancement.

How do these NCERT solutions help in exam preparation?

These solutions provide clear, concise, and accurate answers to the chapter's questions, helping students revise key concepts and understand the expected level of detail for exams.

What is vital capacity?

Vital capacity is the maximum volume of air that can be forcefully exhaled after taking a deep breath. It differs between males and females.
