Define homeostasis and explain its importance in the human body.
Answer:
Homeostasis is the body's ability to maintain a stable internal environment despite changes in external
conditions. It is essential for normal cell function and overall health, involving mechanisms like
temperature regulation and pH balance.
List the bones of the human skull and their functions.
Answer:
The skull includes 22 bones: 8 cranial (e.g., frontal, parietal, occipital) and 14 facial (e.g., maxilla,
mandible). These bones protect the brain, support facial structure, and allow for muscle attachment.
Describe the structure and function of the heart.
Answer:
The heart has four chambers—two atria and two ventricles. It functions as a pump to circulate blood
throughout the body, delivering oxygen and nutrients and removing waste products.
Explain the process of blood circulation in the human body.
Answer:
Blood flows from the heart to the lungs (pulmonary circulation) to exchange gases, then back to the
heart and out to the rest of the body (systemic circulation) to deliver oxygen and nutrients.
What is the role of the respiratory system in maintaining acid-base balance?
Answer:
The respiratory system regulates blood pH by controlling CO₂ levels. An increase in respiration removes
more CO₂, reducing acidity, while slower respiration retains CO₂, increasing acidity.
