Biology Chapter 4 : Topic 7
Maintenance of Homeostasis
1 / 15
Which system mainly controls and coordinates homeostasis in the human body?
Reasoning: The nervous system rapidly detects changes and coordinates responses to maintain balance.
2 / 15
Which system works closely with the nervous system to regulate long-term homeostasis using hormones?
Reasoning: The endocrine system uses hormones to regulate body functions over time.
3 / 15
Which organ system helps maintain oxygen balance in the body?
Reasoning: The respiratory system controls oxygen intake and carbon dioxide removal.
4 / 15
Which system maintains water and salt balance in the body?
Reasoning: The kidneys regulate water and salt levels in blood.
5 / 15
Which organ plays the most important role in filtering blood for homeostasis?
Reasoning: Kidneys remove wastes and maintain internal chemical balance.
6 / 15
Which system helps maintain body temperature through sweating?
Reasoning: Skin regulates temperature by sweating and controlling blood flow.
7 / 15
Which organ helps regulate blood sugar levels for homeostasis?
Reasoning: The pancreas releases insulin and glucagon to control blood glucose.
8 / 15
Which system ensures removal of carbon dioxide to maintain internal balance?
Reasoning: Lungs remove CO² produced during respiration.
9 / 15
Which system provides nutrients required for maintaining homeostasis?
Reasoning: The digestive system supplies nutrients for energy and repair.
10 / 15
Which two systems mainly work together for rapid homeostasis control?
Reasoning: Nervous and endocrine systems coordinate fast and long-term regulation.
11 / 15
Which organ system removes nitrogenous wastes from the body?
Reasoning: The excretory system removes wastes like urea to maintain balance.
12 / 15
Which system transports hormones to different parts of the body?
Reasoning: Blood carries hormones to target organs for regulation.
13 / 15
Why is homeostasis important for enzyme activity in the body?
Reasoning: Enzymes work best in stable internal conditions.
14 / 15
Which system helps maintain pH balance in the human body?
Reasoning: Kidneys help regulate acid-base balance in blood.
15 / 15
Overall homeostasis in the body is maintained by:
Reasoning: All organ systems work together to maintain internal balance.
