Flashcards in Body Systems Deck (17):
What is Cartilage?
It is a strong, smooth substance that stops the bones rubbing together and wearing out
Antagonistic muscles pairs
A pair of muscles that work together to move a joint. As one contracts the other relaxes.
A tissue is made up of many cells and it can come together into many things e.g organs and skin
An organ is a part of your body that is vital for you to live e.g lungs and heart
The functions of the body's organ systems overlap considerably, and your body could not function without the cooperation of all of its organ systems. In fact, the failure of even one organ system could lead to severe disability or even death.
Hierarchy of ornisms
A tendon is a strong cord holding muscles to the bone
A ligament holds together a joint
A bone is like a frame holding together our bodies
A joint is something that holds together are bones and helps us bend parts of our body.
The muscle works to move our body parts. Without them we would be unable to move or smile.
Synovial fluid is inside our joints. It lubricates are joints.
Bone marrow is inside our bones. Our bone marrow produces blood cells, called red blood cells, platelets, and white blood cells. Inside the marrow, blood cells start off as young, immature cells called stem cells. Once they develop, blood cells do not live for a long time inside our bodies.
Inhalation is when you breath in and your chest expands.
Exhalation is when you breath out and your stomach contracts.
The diaphragm is the primary muscle used in the process of inspiration, or inhalation. It is a dome-shaped sheet of muscle that is inserted into the lower ribs. Lying at the base of the thorax (chest), it separates the abdominal cavity from the thoracic cavity.
