Study Notes
Blood Composition
- Blood is composed of plasma and formed elements (cells)
- Plasma makes up about 55% of blood, and formed elements make up about 45%
Plasma Components
- Albumin is the main protein in plasma, and its main function is to regulate osmotic pressure and help maintain blood pressure
- Albumin also helps transport hormones, vitamins, and fatty acids
Blood Cells
- The most abundant cells in vertebrate blood are red blood cells (erythrocytes)
- Red blood cells contain the protein hemoglobin, which facilitates oxygen transport
Nervous System
- The main function of the sympathetic nervous system is to prepare the body for "fight or flight" responses
- The sympathetic nervous system is part of the autonomic nervous system, which is subdivided into sympathetic and parasympathetic systems
Nervous System Evolution
- The central nervous system (CNS) first arose in wormlike organisms about 550 to 600 million years ago
Nervous System Structure
- Nerves in the peripheral nervous system are mainly composed of axons and their supporting cells
- Cranial nerves transmit signals from the brain to the rest of the body
