Study Notes
Body Systems
- A system is a group of parts that work together to perform specific functions.
- The human body has ten different systems that work together to keep us healthy and functional.
Nervous System
- The nervous system consists of the brain, spinal cord, and nerves.
- The brain is the control center of the body, sending signals through the spinal cord to nerves all around the body.
- Nerves are cables that help move signals around to different parts of the body, controlling functions like breathing and blinking.
Respiratory System
- The respiratory system provides the body with oxygen through breathing.
- Air enters the nose and mouth, passes through the trachea in the throat, and enters the lungs.
- In the lungs, oxygen is transferred to the blood, which is then circulated throughout the body.
- Oxygen is essential for powering the body's functions.
Cardiovascular System
- The cardiovascular system consists of the heart and blood vessels (tubes that carry blood).
- The heart pumps blood throughout the body, delivering oxygen and nutrients and helping to protect against diseases.
- Blood vessels carry blood to all parts of the body.
Digestive System
- The digestive system breaks down food into nutrients, absorbs them, and eliminates waste.
- Major parts of the digestive system include the stomach and intestines.
- Nutrients are absorbed from food and circulated throughout the body, providing energy and essential substances.
Musculoskeletal System
- The musculoskeletal system consists of bones and muscles.
- Bones support the body, protect organs, and produce blood cells.
- Muscles are connected to bones, receiving messages from the brain through nerves, and facilitating movement by pulling on bones.
- The largest muscle in the body is the gluteus maximus, which is used for sitting.
