BSC 1005 FSU MOVEMENT AND PHYSIOLOGY TEST
REVIEW QUESTIONS
What is physiology? - Answers - The science of biological function
What is the organization levels in multicellular organisms? - Answers - Atom ->
molecule -> cell -> tissue -> organ -> organ system -> organism
What is homeostasis? What are examples? - Answers - • Maintenance of a constant
internal environment despite external changes, or changes caused by variation in
biological activity within cells, tissues, and organs
• Short-Term: running; Long-Term: high altitudes
• Maintain body temp, heat production, blood glucose concentration, blood and cellular
protein concentration
What is the importance of understanding both normal physiology and pathophysiology?
- Answers - • Pathophysiology: changes in physiology associated with disease
• Helps us to better relate and assist people who experience these diseases
• Helps us develop a better understanding of normal physiological processes
What are the benefits of biomedical research for individuals, families, and society? -
Answers - Reducing disease incidence and severity because of the physical, emotional,
and financial toll on those affected
What system is blood part of? - Answers - Circulatory -> Cardiovascular system
Why is blood considered a type of connective tissue, even though it's a fluid? - Answers
- Connects cells throughout our body as it continuously circulates within blood vessels
What are the major cellular components of blood and blood plasma and their functions?
- Answers - • Blood
- Red blood cells
1. transports oxygen
- White blood cells (leukocytes)
1. Defend against infectious agents (immune system)
- Platelets
1. Blood clotting
- Plasma
1. Carries red cells, white cells, and platelets and provides nutrients
2. Maintain homeostasis and our health
• Blood Plasma
- Water
, - Electrolytes
1. Buffer blood pH to maintain homeostasis
- Small molecules dissolved gasses and food molecules
1. Breakdown of bigger molecules (oils and fats)
- Proteins
1. Helps transport molecules that aren't dissolvable in water (blood bound proteins:
steroid hormones)
- Chemical signals (hormones)
1. Response to different stimuli (low blood O2 triggers EPO from kidneys)
What is a cell? What are the general features of a cell? - Answers - • Basic unit of Life
• Surrounded by a membrane composed of lipids arranged in a bilayer structure
•Contains/ made up of proteins
• Everything resides in the cytoplasm
What is the physiological significance of hematocrit? - Answers - • Hematocrit:
percentage of blood volume that is occupied by RBCs
• Determines carrying capacity of oxygen for blood in normal individuals
What is responsible for the transport of blood around the body and what is it powered
by? - Answers - • Bulk flow of blood
• Pump action of the heart
What is diffusion? - Answers - Mechanism for transport of respiratory gases (o2 and
CO2) between blood plasma and cytoplasm of RBCs
What is the significance of different transport mechanism at different size/ length
scales? - Answers -
What are the forms in which each respiratory gas is transported? - Answers - •
Hemoglobin and carbonic anhydrase in RBCs
- Bond respiratory gases to cell
What are the effects of blood flow? - Answers - • Transports nutrients and metabolic
wastes
• Transports chemical signals (hormones)
• regulates body temp
• fights infections
• clotting (coagulation)
Whats are the advantages of vaccinations? - Answers - Serve as initial exposure to an
infectious agent, but without the accompanying illness
Where and how are blood cells and platelets formed? - Answers - BLOOD
