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  Joints Ligaments Cartilage Skeletal System

Skeletal System Structure (What is is) Bones have a hard outer layer. Bones attach to each other through ligaments and joints Bones attach to muscles through tendons. Skeletal System

Skeletal System Function (What it does) Protection Movement Storage Support Red blood cell production Skeletal System

Muscular System Major Parts Skeletal Muscle Smooth Muscle Cardiac Muscle Muscular System

Muscular System Structure (What is is) Involuntary and voluntary Fibrous Tissue Muscular System

Muscular System Function (What it does) Used for movement Skeletal muscle can be controlled, smooth and cardiac muscle cannot. Muscular System

How do these two systems interact (useful for your project) Major Parts for Skeletal System Bone -Cartilage -Ligaments -Joints Major Parts for Muscular System Skeletal Muscle -Smooth Muscle -Cardiac Muscle https://www.youtube.com/watch?v=WNBIN3P0VzA How do these two systems interact (useful for your project)

Cardiovascular/ Circulatory System Major Parts Heart Blood Blood vessels (Lymphatic System) Cardiovascular/ Circulatory System

Cardiovascular/ Circulatory System Structure (What it is) Heart is a muscle in constant motion Blood transports oxygen, hemoglobin, hormones and nutrients Vessels lined with smooth muscle Cardiovascular/ Circulatory System

Cardiovascular/ Circulatory System Function (What it does) Heart pumps blood through veins Delivers oxygen from lungs through hemoglobin in red blood cells Maintains homeostasis Cardiovascular/ Circulatory System

Cardiovascular/ Circulatory System Notes (on left side of notebook, if you’ve run out of room, turn the page and still use the left side.) 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 “lub-dub” 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. Cardiovascular/ Circulatory System

Major Parts Nose Larynx Trachea Bronchioles Alveoli Respiratory System

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 Respiratory System

Oxygen travels from the nose/ mouth to the pharynx, the larynx, trachea, bronchioles, and alveoli. The alveoli are tiny sacs that diffuse oxygen into blood vessels located there. Respiratory System

How to keep the systems healthy

Lung health

Interaction

Digestive System Major Parts: Mouth Esophagus Stomach Small Intestine Large Intestine Rectum Anus Digestive System

Digestive System Structure (What it is) Teeth and saliva in the mouth Esophagus: muscle tube Stomach: muscular organ Intestines: smooth muscle tissues Rectum and anus are at the end of the system for feces Digestive System

Digestive System Function (What it does) Mechanical Digestion (chewing) Chemical Digestion (saliva, acid, and enzymes) Breaks down food into basic nutrients Package unused digestive wastes Digestive System

Digestive System Additional Notes: -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. Digestive System

November 12th new due date, things need to be ready that day, presentations to come in days after. Project Due Date

Excretory System Major Parts: Skin (largest organ) Kidneys Bladder Lungs Excretory System

Excretory System Structure (What it is) Skin has sweat glands Kidneys filter Bladder: muscular and elastic Lungs deflate Excretory System

Excretory Systems Function (What it does) Regulates body temperature Filters food and water Excretes waste Excretory Systems

Excretory System Additional Notes: Sweat glands in skin regulate body temperature. Kidneys and bladder excrete waste. Lungs exhale CO2 Excretory System

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: Immune System: Me: We also can’t survive outside 100 degrees for long.
