Body Systems Flashcards
What is the Muscular System and what organs does it use?
primary function is to move the body by attaching to bones.
It also makes up organs like the HEART,
DISGESTIVE ORGANS and BLOOD VESSELS
What is the Cardiovascular/Circulatory System?
The cardiovascular system (also called the circulatory system) is like the body’s transportation network. It moves blood around to deliver oxygen and nutrients to all the cells and takes away waste like carbon dioxide.
What is the Nervous System and what is the organs does it use?
The nervous system includes the BRAIN, SPINAL CORD, and a complex network of nerves. This system sends messages back and forth between the brain and the body. The BRAIN is what controls all the body’s functions.
What organs does the Cardiovascular/Circulatory System use?
- HEART: A powerful muscle that pumps blood.
- BLOOD VESSELS: These are like roads or pipes that carry blood:
- ARTEIES: Carry oxygen-rich blood from the heart to the body.
- VEINS: Bring oxygen-poor blood back to the heart.
- CAPILLARIES: Tiny vessels where oxygen and nutrients move from the blood to cells.
What is the Excretory/Urinary
System?
The excretory system (also called the urinary system) helps the body get rid of waste and extra water. It acts like the body’s cleaning system, making sure harmful things don’t build up inside.
What organs does the Excretory/Urinary
System use?
- KIDNEYS: Two bean-shaped organs that filter blood, removing waste and extra water to make urine.
- URETERS: Thin tubes that carry urine from the kidneys to the bladder.
- BLADDER: A muscular sac that stores urine until you are ready to pee.
- URETHRA: A tube that carries urine out of the body when you urinate.
What does the respiratory system do? What is it?
The respiratory system helps your body breathe by bringing in oxygen and getting rid of carbon dioxide (a waste gas). It’s like the body’s air supply system!
What organs does the respiratory system use?
- NOSE AND MOUTH: Air enters through here.
- TRACHEA (windpipe): A tube that carries air from the nose/mouth to the lungs.
- BRONCHI: Two large tubes that branch off the trachea and lead into the lungs.
- LUNGS: The main organs where oxygen is absorbed, and carbon dioxide is released.
- ALVEOLI: Tiny air sacs in the lungs where the oxygen and carbon dioxide swap places with the blood.
- DIAPHRAGM: A muscle under the lungs that helps you breathe in and out.
What does the Digestive
System do? What is it?
The digestive system helps your body BREAKS DOWN FOOD into smaller pieces so you can get the energy and nutrients you need. It also gets rid of waste from food your body doesn’t use.
What organs does the Digestive
System do?
- MOUTH: Where digestion begins by chewing food and mixing it with saliva.
- ESOPHAGUS: A tube that moves food from the mouth to the stomach.
- STOMACH: A sack that mixes food with acids and enzymes to break it down further.
- SMALL INTESTINE: A long tube where most nutrients from food are absorbed into the blood.
- LIVER: Helps by producing bile (a fluid that breaks down fats) and filtering toxins.
- GALLBLADDER: Stores bile and releases it when needed.
Pancreas: Makes enzymes that help digest food in the small intestine. - LARGE INETSINE: Absorbs water and forms waste into solid poop.
- RECTUM and ANUS: Store and release poop from the body.
What is the Immune/Lymphatic
System?
The immune/lymphatic system works together to protect your body from germs, infections, and diseases. It’s like your body’s defense army that fights off anything harmful.
What organs does the Immune/Lymphatic
System use?
- Lymph Nodes: Small, bean-shaped structures that filter germs and harmful things from lymph (a fluid that travels through the body).
- Lymph Vessels: Tubes that carry lymph fluid throughout the body.
- Spleen: An organ that filters the blood, removes old or damaged blood cells, and helps fight infections.
- Thymus: A small organ where certain immune cells (T-cells) grow and learn to fight germs.
- Tonsils and Adenoids: Help trap germs that enter through the mouth or nose.
- Bone Marrow: A spongy material inside bones where blood cells (including immune cells) are made.
- White Blood Cells: Special cells that travel through your blood and attack germs and infections.
What body system breaks down food?
Digestive System
What body system controls movement of the human body?
Nervous System
What human body system is responsible for allowing you to move like walking, running and jumping?
Muscular System
What is the function of the digestive system?
It breaks down food so the nutrients can be absorbs by your body
Muscular tube connecting the mouth to the stomach
