Study Notes
Circulatory System
- The circulatory system is primarily responsible for transporting nutrients and oxygen throughout the body.
Cell
- The cell is the primary structural and functional unit of the body.
Intracellular Fluid
- Intracellular fluid is characterized by a higher concentration of potassium compared to extracellular fluid.
Osmolarity
- Osmolarity describes the number of particles of solute per liter of solution.
Nervous System
- The nervous system is not considered one of the primary systems of the body in physiology.
Albumin Deficiency
- Albumin deficiency can lead to edema (swelling) due to decreased osmotic pressure in the blood.
Biconcave Shape
- The biconcave shape of red blood cells (RBCs) increases their surface area, facilitating efficient gas exchange.
Oxygen Deficiency
- Hypoxia is defined as a deficiency of oxygen in the tissues.
Hemoglobin Function
- Hemoglobin, found in red blood cells, primarily serves to bind and transport oxygen throughout the body.
Red Blood Cell Aging
- Red blood cells lose their flexibility and become less efficient at transporting oxygen as they age.
