Physiology Test review (baby Bio) fully
solved A+
What is physiology? - correct answer ✔✔The science of biological function
What is the organization levels in multicellular organisms? - correct answer ✔✔Atom ->
molecule -> cell -> tissue -> organ -> organ system -> organism
What is homeostasis? What are examples? - correct answer ✔✔• 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? -
correct answer ✔✔• 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? - correct
answer ✔✔Reducing disease incidence and severity because of the physical, emotional, and
financial toll on those affected
What system is blood part of? - correct answer ✔✔Circulatory -> Cardiovascular system
, Why is blood considered a type of connective tissue, even though it's a fluid? - correct answer
✔✔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? -
correct answer ✔✔• 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)
