6 Questions
What are the key topics covered in the Human Physiology unit of the UP Board Class 12 Biology syllabus?
Digestion, Respiration, Circulation, Excretion, Nervous System
List the key organs and functions associated with the Circulatory system in Human Physiology.
Heart, Blood vessels, Blood; Functions: Transport of nutrients, gases, and waste products
Explain the role of enzymes in digestion.
Enzymes help in breaking down complex food molecules into simpler forms for absorption.
What is the main function of the Kidneys in the context of Human Physiology?
The main function of the Kidneys is to filter blood, remove waste products, and regulate fluid balance.
Describe the components of Blood and their respective roles in the human body.
Blood components include Red blood cells (carry oxygen), White blood cells (immunity), Platelets (blood clotting), Plasma (transport of nutrients and waste)
What are the different nervous systems discussed in Human Physiology?
Central Nervous System, Peripheral Nervous System, Autonomic Nervous System, Somatic Nervous System
