Body Systems Notes
Body System Notes We will be learning about 8 different body systems. Many of these systems work together for a similar function. Please use this information to work on your project.
§ Major Parts § Bones Skeletal System § Joints § Ligaments § Cartilage
§ Structure (What is is) § Bones have a hard outer layer. Skeletal System § Bones attach to each other through ligaments and joints § Bones attach to muscles through tendons.
§ Function (What it does) § Protection Skeletal System § Movement § Storage § Support § Red blood cell production
§ Major Parts Muscular System § Skeletal Muscle § Smooth Muscle § Cardiac Muscle
Muscular System § Structure (What is is) § Involuntary and voluntary § Fibrous Tissue
§ Function (What it does) Muscular System § Used for movement § Skeletal muscle can be controlled, smooth and cardiac muscle cannot.
§ Major Parts for Skeletal System § Bone How do these two systems interact (useful for your project) -Cartilage -Ligaments -Joints § Major Parts for Muscular System § Skeletal Muscle -Smooth Muscle -Cardiac Muscle https: //www. youtube. com/watch? v=WNBIN 3 P 0 Vz. A
§Major Parts Cardiovascular/ Circulatory System § Heart § Blood vessels § (Lymphatic System)
§Structure (What it is) Cardiovascular/ Circulatory System § Heart is a muscle in constant motion § Blood transports oxygen, hemoglobin, hormones and nutrients § Vessels lined with smooth muscle
§Function (What it does) §Heart pumps blood through Cardiovascular/ Circulatory System veins §Delivers oxygen from lungs through hemoglobin in red blood cells §Maintains homeostasis
§ Notes (on left side of notebook, if you’ve run out of room, turn the page and still use the left side. ) Cardiovascular/ Circulatory System § Heart-cardiac muscle, right side pumps oxygen poor blood to the lungs. Left side pumps oxygen-rich blood to the body. Made up of four chambers, valves cause “lubdub” sound. § Blood- connective tissue, serves as a transport system through miles of vessels in the body § Blood vessels- 3 kinds. Artery-> carries blood away from the heart. Capillary->Tiny blood vessel exchanges between body cells and blood. Vein->carries blood back to the heart.
§Major Parts § Nose Respiratory System § Larynx § Trachea § Bronchioles § Alveoli
§Structure (What it is) Respiratory System § Air travels from nose and mouth through tubes § Lungs are like balloons § Alveoli are tiny sacs
Respiratory System §Function (What it does) § Takes in Oxygen for blood § Releases waste in the form of Carbon Dioxide
§ Oxygen travels from the nose/ mouth to the pharynx, the Respiratory System larynx, trachea, bronchioles, and alveoli. § The alveoli are tiny sacs that diffuse oxygen into blood vessels located there.
How to keep the systems healthy
Lung health
Interaction
§ Major Parts: § Mouth Digestive System § Esophagus § Stomach § Small Intestine § Large Intestine § Rectum § Anus
§ Structure (What it is) § Teeth and saliva in the mouth Digestive System § Esophagus: muscle tube § Stomach: muscular organ § Intestines: smooth muscle tissues § Rectum and anus are at the end of the system for feces
§Function (What it does) Digestive System § Mechanical Digestion (chewing) § Chemical Digestion (saliva, acid, and enzymes) § Breaks down food into basic nutrients § Package unused digestive wastes
§ Additional Notes: Digestive System § -Mechanical and chemical digestion happens in the mouth. Food travels down the esophagus to the stomach. § -The stomach is full of acids and enzymes. Intestines absorb water and nutrients for energy…and make poop.
§November 12 th new due Project Due Date date, things need to be ready that day, presentations to come in days after.
§ Major Parts: Excretory System § Skin (largest organ) § Kidneys § Bladder § Lungs
§Structure (What it is) Excretory System § Skin has sweat glands § Kidneys filter § Bladder: muscular and elastic § Lungs deflate
§Function (What it does) Excretory Systems § Regulates body temperature § Filters food and water § Excretes waste
§ Additional Notes: Excretory System § Sweat glands in skin regulate body temperature. § Kidneys and bladder excrete waste. § Lungs exhale CO 2
Me: Immune system, why do I have a fever? Immune System: Well, the bacteria can’t survive outside 100 degrees for long so I thought I’d raise the temperature to kill them off! Me: Immune system: Me: Immune System: Me: We also can’t survive outside 100 degrees for long. Immune System:
