Study Material

What is Transportation?

English

Transportation is the process of moving food, water, oxygen, minerals, and waste materials from one part of the body to another.

हिन्दी

शरीर के एक भाग से दूसरे भाग तक भोजन, जल, ऑक्सीजन, खनिज एवं अपशिष्ट पदार्थों के पहुँचने की प्रक्रिया परिवहन कहलाती है।

Transportation in Animals

Circulatory System (परिसंचरण तंत्र)

The circulatory system consists of:

  • Heart
  • Blood
  • Blood Vessels

हिन्दी

परिसंचरण तंत्र के मुख्य भाग—

  • हृदय
  • रक्त
  • रक्त वाहिकाएँ

Blood (रक्त)

Blood is a liquid connective tissue.

Components of Blood

1. Plasma (प्लाज़्मा)

  • Liquid part of blood.
  • Transports food, hormones, and waste materials.

2. Red Blood Cells (RBCs) (लाल रक्त कण)

  • Carry oxygen.
  • Contain haemoglobin.

3. White Blood Cells (WBCs) (श्वेत रक्त कण)

  • Fight germs.
  • Protect the body from diseases.

4. Platelets (प्लेटलेट्स)

  • Help in blood clotting.

Functions of Blood

  • Carries oxygen.
  • Transports food.
  • Removes waste.
  • Fights diseases.
  • Regulates body temperature.

Heart (हृदय)

English

The heart is a muscular organ that pumps blood throughout the body.

  • Located slightly to the left side of the chest.
  • About the size of a clenched fist.
  • Has four chambers:
    • Right Atrium
    • Right Ventricle
    • Left Atrium
    • Left Ventricle

हिन्दी

हृदय एक मांसल अंग है जो पूरे शरीर में रक्त पंप करता है।

  • छाती के बाईं ओर स्थित होता है।
  • मुट्ठी के आकार का होता है।
  • इसमें चार कक्ष होते हैं।

Blood Vessels

Arteries (धमनियाँ)

  • Carry blood away from the heart.
  • Thick and elastic walls.

Veins (शिराएँ)

  • Carry blood towards the heart.
  • Have valves to prevent backflow.

Capillaries (केशिकाएँ)

  • Very thin blood vessels.
  • Exchange oxygen, nutrients, and waste with body cells.

Pulse Rate (नाड़ी)

Pulse is the rhythmic throbbing of arteries caused by the beating of the heart.

Normal pulse rate:

70–100 beats per minute (adults at rest).

Children generally have a faster pulse rate.

Excretion in Humans

English

Excretion is the removal of waste products from the body.

Main excretory organs:

  • Kidneys
  • Ureters
  • Urinary bladder
  • Urethra

हिन्दी

शरीर से अपशिष्ट पदार्थों को बाहर निकालने की प्रक्रिया उत्सर्जन कहलाती है।

मुख्य उत्सर्जी अंग—

  • वृक्क (गुर्दे)
  • मूत्रवाहिनी
  • मूत्राशय
  • मूत्रमार्ग

Transportation in Plants

Plants need transportation because:

  • Roots absorb water and minerals.
  • Leaves prepare food.
  • Food must reach every part of the plant.

Xylem (जाइलम)

Function

Carries:

  • Water
  • Minerals

Direction:

Roots → Stem → Leaves

हिन्दी

जाइलम जड़ों से पत्तियों तक जल एवं खनिज पहुँचाता है।

Phloem (फ्लोएम)

Function

Carries prepared food from leaves to all parts of the plant.

Direction:

Leaves ↔ Stem ↔ Roots (both upward and downward)

हिन्दी

फ्लोएम पत्तियों द्वारा बनाए गए भोजन को पौधे के सभी भागों तक पहुँचाता है।

Transpiration (वाष्पोत्सर्जन)

English

The loss of water as water vapour from leaves through stomata is called transpiration.

Importance:

  • Helps pull water upward.
  • Cools the plant.
  • Maintains water balance.

हिन्दी

पत्तियों के रंध्रों से जल का वाष्प के रूप में निकलना वाष्पोत्सर्जन कहलाता है।

Classroom Activities

Activity 1 – Feel Your Pulse

Students:

  • Count pulse for one minute.
  • Compare before and after light exercise.

Observation:

Pulse increases after exercise.

Activity 2 – Coloured Water Experiment

Materials:

  • White flower or celery stem
  • Red/Blue food colour
  • Water

Observation:

After a few hours, coloured veins appear in the stem or petals.

Conclusion:

Water moves upward through xylem.

Activity 3 – Transport Game

Students act as:

  • Heart
  • Blood
  • Oxygen
  • Food
  • Waste
  • Kidneys

This role-play demonstrates circulation and excretion.

Activity 4 – Label the Heart

Students label:

  • Heart
  • Arteries
  • Veins
  • Capillaries
