Cells Flashcards
What is the role of pH balance in cells?
Cells require specific pH levels to function correctly.
pH levels influence enzyme activity and cellular processes.
How do cells obtain oxygen and nutrients?
Adequate oxygen must reach cells via bloodstream to support metabolism and energy production.
Oxygen is essential for cellular respiration.
At what temperature do cells function best?
Cells function best at body temperature 37°C.
Deviations from this temperature can impair cellular functions.
What is the primary function of red blood cells?
Carry oxygen from lungs to tissues and remove carbon dioxide.
Red blood cells contain hemoglobin to facilitate oxygen transport.
What is the role of white blood cells?
Defend the body against infection and disease.
White blood cells are key components of the immune system.
What do muscle cells do?
Contract to produce movement.
Muscle cells respond to signals from the nervous system for controlled movements.
What is the function of nerve cells (neurons)?
Transmit electrical signals to communicate between the brain and other parts.
Neurons are essential for the nervous system’s functioning.
What do epithelial cells form?
Protective barriers and are involved in absorption and secretion.
Epithelial cells line surfaces and cavities in the body.
What is the prefix for muscle cells?
MYO-
This prefix is commonly used in medical terminology related to muscle.
What is the prefix for bone cells?
OSTEO-
This prefix is often used in medical terminology related to bone.
True or False: Muscle cells contract independently of nervous system signals.
False.
Muscle cells require signals from the nervous system to contract.
