Body Systems Flashcards
molecules
molecules are two or more atoms joined (bonded) together, forming a small particle
organelles
organelles are small structure in a cell with a special function
cells
cells are the smallest unit of life. Cells are the building blocks of living things. There are many different sized and shaped cells in animals and plants, as well as single-celled organisms.
tissues
tissues are groups of cells performing the same function
cellular respiration
cellular respiration is the chemical reaction involving oxygen that moves the energy in glucose into the compound ATP. The body is able to use the energy contained in ATP.
respiratory system
respiratory system is the body system involving the lungs and associated structures, which take in air and supply the blood with oxygen to deliver to the body’s cells so they can carry out their essential functions; it also performs gas exchange to remove the waste gas carbon dioxide
circulatory system
circulatory system is the body system that circulates oxygen in blood to all the cells of the body. The circulatory system consists of the heart, the blood vessels and blood.
blood cells
blood is any of the many types of cells found in blood including red and white blood cells
blood vessels
blood vessels are the veins, arteries and capillaries through which the blood flows around the body
heart
The heart is a muscular organ that pumps blood through the circulatory system so that oxygen and nutrients can be transported to the body’s cells and wastes can be transported away
Capillary
A Capillary transports blood through capillary bases through 1 cell wide tubes.
