Study Notes
Human Nervous System
- The central nervous system (CNS) acts as the body's control center.
- The brain, composed of 100 billion neurons, is part of the CNS.
- The cerebrum controls thought and senses.
- The cerebellum controls motor functions.
- The spinal cord is a part of the CNS that transmits instructions between the brain and the rest of the body.
- Nerves conduct impulses to muscle cells throughout the body.
- Interneurons connect sensory and motor neurons.
- A synapse is the point where a neuron transfers an impulse to another cell.
Respiratory System
- The respiratory system's primary function is to supply the body with oxygen for cellular respiration and remove carbon dioxide waste.
- Alveoli, resembling clusters of grapes, are where gas exchange with the blood occurs.
- Capillaries surround each alveolus, facilitating gas exchange.
Cardiovascular System
- The heart and circulatory system comprise the cardiovascular system.
- The heart acts as a pump, propelling blood to organs, tissues, and cells.
- Valves regulate blood flow between the chambers of the heart.
