Study Notes

1.4-1.7 Words to Learn

Oxygen: A colorless gas, a component of air
Carbon dioxide: A colorless gas, a component of air; breathed out during respiration; used by plants in photosynthesis
Host: The living organism a parasite infects
Bacteria: An organism living on or in another organism, can cause disease
Parasite: Tiny organism that causes infection
Fungi: Living organisms that acquire food from the environment
Infection: A disease or illness that transmits from one place to another
Transmit: To cause something (a disease or illness) to spread
Vector: An organism, like an insect, that transmits disease or parasites from one animal/plant to another
Physical barrier: Prevents germs from entering the body (e.g., skin)
Chemical barrier: Destroys germs on body surfaces (e.g., mucus)
Mucus: A slimy substance in the body
Microorganisms/Microbes: Tiny living organisms not visible to the naked eye

1.2 The Respiratory System

Function: Allows breathing in oxygen and breathing out carbon dioxide
Organs: Nose, trachea, lungs, and diaphragm
Breathing Process: Inhalation/exhalation
Diaphragm: Muscle below lungs that aids breathing
Respiratory Disorders: Asthma, bronchitis, pneumonia
Maintaining Health: Avoid smoking, ensure good air quality, exercise, and good hygiene

1.3 The Reproductive System - Key Facts About Puberty

Puberty Changes: Physical changes in the bodies of boys and girls, especially in the reproductive system, enabling reproduction
Reproductive System's Role: To create special cells for reproduction
Boys Produce Sperm: Male sex cells
Girls Develop Eggs/Ova: Female sex cells
Fertilization: Sperm and egg unite forming a new living being

Boys During Puberty

Begin producing sperm during puberty

Girls During Puberty

Develop eggs
Menstruation begins (a year after puberty) - egg and lining of uterus are released

Changes in the Reproductive System - Key Facts About Puberty

Puberty: Stage of life when the body changes and becomes capable of reproduction
Age of Puberty: Boys ~13, Girls ~11
Cause of Changes: Hormones (chemicals in body)
Growth Spurt: Height increase
Changes in Hair: Growth on face, armpits, and other body parts (boys); armpits and other body parts (girls)
Skin Changes: Oily skin, pimples (boys and girls)
Changes in Boys: Broad shoulders/chest, muscle development, deepening voice
Changes in Girls: Wider hips, breast development, deepening voice

Male Reproductive System

Testes: Produce sperm
Sperm duct: Carries sperm
Penis: Transfers sperm to the female body

Female Reproductive System

Ovaries: Produce ova/eggs
Uterus/Womb: Where the baby develops
Oviducts: Site of fertilization
Birth canal: Passage for the baby

Microorganism

Bacteria: Single-celled organisms, found in various environments (Some cause, others are beneficial)
Viruses: Not considered living, replicate by infecting cells
Fungi: Multicellular organisms (Molds, Yeasts, Mushrooms).
Parasites: Live on and inside another organism

1.4 Infectious Diseases

Definition: Illnesses caused by tiny germs (bacteria, viruses, parasites)
Transmission: Spreads through air, water, touch, or insects (mosquitoes)
Symptoms: Common signs (fever, cough, tiredness, stomach issues.)

Body Defenses

Skin: Acts as a barrier to prevent germs from entering the body
Stomach Acid: Kills germs in food consumed
