What are the types of transport systems in human beings? What is the difference between both of them?
Answers
The two types of transport system in human beings are: • Lymphatic system. • Blood vascular system
Answer:
The two types of transport system in human beings are:-
1. Circulatory System- consists of blood, blood vessels and heart
2. Lymphatic System- consists of lymph, lymph nodes and lymph vessels
The differences between both of them are:-
1. The primary fluid that transports substances in the circulatory system is blood while in that of lymphatic system is lymph.
2. The blood contains plasma, erythrocytes, leucocytes and thrombocytes while the lymph contains plasma and leucocytes.
3. The plasma of blood has more proteins, calcium and phosphorus while the plasma of lymph contains fewer proteins and less calcium and phosphorus.
4. Blood in circulatory system carries materials towards and away from the tissue, therefore, it acts as a 'vehicle' whereas lymph in lymphatic system transfers materials from the blood to the body cells and vice versa therefore, it acts as a 'middle-man'
