NOTE
SYSTEMS OF THE BODY
The eight major systems of the human body are:
Circulatory system
This system includes the heart, blood vessels, and blood. Its primary function is to transport oxygen, nutrients, hormones, and other substances throughout the body and remove waste products.
- Transports oxygen, nutrients, hormones, and waste products throughout the body.
- Regulates body temperature and pH balance.
- Helps in immune response and clotting.
Respiratory system
Comprised of the lungs, airways, and respiratory muscles, this system facilitates the exchange of oxygen and carbon dioxide between the body and the environment through breathing.
- Facilitates the exchange of oxygen and carbon dioxide between the body and the environment.
- Helps regulate pH balance in the body.
- Filters and humidifies air entering the lungs.
Nervous system
The nervous system consists of the brain, spinal cord, nerves, and sensory organs. It controls and coordinates voluntary and involuntary actions and transmits signals between different parts of the body.
- Controls and coordinates voluntary and involuntary actions.
- Receives and interprets sensory information.
- Regulates bodily functions and maintains homeostasis.
Digestive system
This system involves the organs responsible for digestion and nutrient absorption, including the mouth, esophagus, stomach, intestines, liver, and pancreas. It breaks down food into nutrients that can be used by the body for energy and growth.
- Breaks down food into nutrients that can be absorbed by the body.
- Absorbs water and electrolytes.
- Eliminates waste products from the body.
Muscular system
Composed of skeletal muscles, smooth muscles, and cardiac muscles, this system enables movement, maintains posture, and generates heat.
- Enables movement of the body and its parts.
- Maintains posture and stability.
- Generates heat through muscle contractions.
Skeletal system
Made up of bones, cartilage, and ligaments, the skeletal system provides structural support, protects organs, produces blood cells, and stores minerals such as calcium and phosphorus.
- Provides structural support and protection for the body.
- Facilitates movement by serving as attachment points for muscles.
- Produces blood cells and stores minerals.
Endocrine system
This system consists of glands that secrete hormones, which regulate various bodily functions such as metabolism, growth, reproduction, and mood.
- Regulates metabolism, growth, development, and reproduction.
- Helps maintain homeostasis by releasing hormones into the bloodstream.
- Coordinates responses to stress and environmental changes.
Immune system
Comprising white blood cells, lymph nodes, the spleen, and other tissues and organs, the immune system defends the body against pathogens, infections, and foreign substances, helping to maintain health and prevent illness.
- Defends the body against pathogens, such as bacteria, viruses, and parasites.
- Removes damaged or abnormal cells.
- Recognizes and responds to foreign substances to maintain health and prevent illness.
EVALUATION: 1. Identify 5 systems in the body
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the students positively
