Study Notes
Circulatory System
- Arteries: Carry blood from the heart to the body.
- Veins: Carry blood from the body to the heart.
- Capillaries: Tiny vessels connecting arteries and veins.
- Blood Components:
- Platelets: Aid wound healing.
- Red Blood Cells: Transport oxygen and carbon dioxide.
- White Blood Cells: Fight infection.
Digestive System
- Small Intestine: Transfers food to the circulatory system.
- Kidney: Filters waste from the blood.
- Salivary Glands: Produce saliva for food moistening and breakdown.
- Digestive System Order: Teeth, Salivary Glands, Esophagus, Stomach, Small Intestine, Villi, Arteries, Large Intestines.
Respiratory System
- Alveoli: Tiny sacs where oxygen diffuses into capillaries.
- Trachea: Connects the nose to the lungs.
- Diaphragm: Muscle aiding inhalation and exhalation.
- Cilia: Hair-like structures removing airborne particles.
Integumentary System
- Skin: Outer protective layer.
- Hair: Body covering.
- Nails: Protective structures at the ends of fingers and toes.
Skeletal System
- Bones: Structural framework of the body.
Immune System
- Lymph Nodes: Part of the immune response.
- Bone Marrow: Produces blood cells, including immune cells.
- Thyroid: Gland with immune system functions.
Systems and Functions
- Respiratory System: Exchanges oxygen and carbon dioxide through inhalation and exhalation.
- Digestive System: Breaks down food for cell use.
- Excretory System: Filters waste from the blood, regulating composition and removing waste fluids.
- Circulatory System: Transports nutrients, gases, and wastes using blood.
- Nervous System: Coordinates body functions and reacts to sensory information.
Main Organs by System
- Respiratory: Bronchi, bronchioles, lungs, trachea, alveoli, diaphragm, larynx.
- Digestive: Liver, large intestine, gallbladder, stomach, esophagus, small intestine, anus, pancreas, villi.
- Circulatory: Capillaries, heart, arteries, veins.
Processes
- Oxygen Transfer:
- Nasal passages → Trachea → Bronchi → Bronchioles → Alveoli
- Diffusion of oxygen into capillaries
- Oxygen-rich blood carried to the body's cells.
- Food Transfer:
- Food nutrients transferred via diffusion from the villi into capillaries.
- Nutrients distributed to cells.
Health Essentials
- Clean Air: Provides essential oxygen.
- Nutritious Food: Supports body functions and repair.
- Exercise: Helps reduce fat.
- Rest: Facilitates body repair and growth.
Diseases
- Circulatory:
- Hypertension: High blood pressure from smoking, stress, or high salt intake.
- Arteriosclerosis: Hardening of arteries due to plaque.
- Stroke: Brain artery blockage causing oxygen deprivation.
- Heart Attack: Blocked arteries restrict blood flow to the heart.
- Respiratory:
- Emphysema: Lung damage related to smoking or pollution.
- Bronchitis: Cilia damage leads to blocked airways.
- Lung Cancer: Uncontrolled cell growth from smoking.
- Digestive:
- Peptic Ulcer: Stomach/intestine damage from acid, behavior, or stress.
- Colon Cancer: Insufficient dietary fiber linked.
Connections
- The digestive, circulatory, and respiratory systems function together in a complex way. Food is broken down, nutrients absorbed, and oxygen carried to cells, fueling bodily processes.
Eleven Systems (Summary)
- Integumentary (skin)
- Skeletal (bones)
- Muscular (muscles)
- Nervous (brain)
- Cardiovascular/Circulatory (blood)
- Lymphatic (lymph nodes)
- Respiratory (breathing)
- Digestive (digestion)
- Urinary/Excretory (kidneys)
- Endocrine (pancreas)
- Reproductive (reproduction)
