Plant Organs 🌱
The 4 main organs of the plant
Roots, Stem, Leaves, and Flowers
Name one organ in the digestive system and its function
Stomach - breaks down food by its juices
Skeleton made of
Bones
What kind of joint is the elbow
Hinge joint
Scientists who study the body parts as locations
Anatomists
The organ that makes food for the plant
Leaf by photosynthesis
Main job of the circulatory system
To carry oxygen, food, and waste through blood
3 Functions of skeleton
Movement, Protection and Support
Bones that form the ball-and-socket joint in the shoulder
Humerus and scapula
Scientists who study how the body work, giving examples
Physiologists like sport physiologists and neuroscientist
Roots are very important
They absorb water and minerals
Name 6 organ systems
Respiratory system, Circulatory system, Digestive system, Excretory system, Skeletal system, and Nervous system
5 bones in a human arm
Scapula, humerus, ulna, radius, and carpals
Something connects bones to muscles and why they do not stretch
Tendons, so muscles can pull bones firmly
Scan uses X-rays to take 3D pictures of the body
CAT scan
Leaf called the "food factory" of the plant
Because it has chlorophyll that let it able to make food through photosynthesis using sunlight, carbon dioxide, and water
Respiratory and circulatory systems work together
Lungs add oxygen to the blood, and the heart pumps it around the body
Long bones are hollow inside
To make them lighter but still strong
How do biceps and triceps work together with mentioning the team's name
One contracts, the other relaxes, to move the arm (antagonistic muscles)
Mention the 3 tools that anatomists use mentioning difference between them
MRI scan (use magnet), CAT scan (use x-ray), and X-ray (for bones only)
Stomata in the leaf help the plant
They control gas exchange (oxygen, carbon dioxide, water vapor).
Building block of nervous system
Human without skeleton
The body would collapse (no shape, no protection, no movement)
Mention 2 parts of a moveable joint that reduces friction and how
Cartilage and Synovial fluid by covering the two ends of the bones and fill the spaces between the two bones
Why do we need both anatomists and physiologists to study the human body
Anatomists show structure, physiologists explain function → together they give a full understanding of the body
