Nervous
What is the cardiovascular system
The cardiovascular system is the body system made up of the heart, blood, and blood vessels. It transports oxygen, nutrients, hormones, and removes waste products.
What is the skeletal system
The skeletal system is the body system made up of bones, cartilage, and ligaments. It supports the body, protects organs, and helps with movement
What is the respiratory system
The respiratory system is the body system that allows you to breathe. It brings oxygen into the body and removes carbon dioxide
Where does the digestion system start
Mouth
What is the endocrine system
The endocrine system is a group of glands that produce and release hormones into the bloodstream to control body functions like growth, metabolism, mood, and reproduction.
What are the main parts of the cardiovascular system
Heart
Blood vessels (arteries, veins, capillaries)
Blood
What protects the brain
The skull (cranium)
Why is oxygen important
Oxygen is needed for cellular respiration, which allows cells to produce energy
What is the muscular tube that connects the pharynx to the stomach
esophagus
What are hormones
Hormones are chemical messengers that travel through the bloodstream to target organs and tissues to regulate body processes
What is the function of the heart
The heart is a muscular organ that pumps blood throughout the body
What protects the heart and lungs
The rib cage
What is the function of the lungs
The lungs exchange oxygen and carbon dioxide between the air and the blood
What is the role of the large intestine
Absorbing water and preparing waste for elimination
What is the function of the pancreas in the endocrine system
The pancreas produces insulin and glucagon to regulate blood sugar levels
What is the function of red blood cells
Red blood cells carry oxygen using a protein called hemoglobin
What are the main functions of the skeletal system
Support the body
Protect organs (like the brain and heart)
Help with movement
Produce blood cells
Store minerals (like calcium)
What are alveoli
Alveoli are tiny air sacs in the lungs where oxygen enters the blood and carbon dioxide leaves the blood
True or False: The gallbladder produces bile
False
What is homeostasis
Homeostasis is the body’s ability to maintain stable internal conditions, like temperature and blood sugar level
What are the four chambers of the heart
Right atrium
Right ventricle
Left atrium
Left ventricle
What is a common skeletal system disorder
Osteoporosis (weak, brittle bones)
Fractures (broken bones)
Scoliosis (curved spine)
How do the respiratory and cardiovascular systems work together
The respiratory system brings oxygen into the lungs. The cardiovascular system carries that oxygen in the blood to the rest of the body
