Life Science

• Red blood cells have a large surface area to take up and deliver oxygen.
• Nerve cells (neurons) are long and thin to send signals throughout the body.
• Most veins carry deoxygenated blood, but the pulmonary veins transport oxygen-rich blood from the lungs to the heart.
• Muscle cells have long fibers made of protein that slide past each other to contract or relax.
• Cells are the smallest unit of life.
• Cells all have similar components but become specialized to carry out specific functions.
• A tissue is made up of many cells of the same type coordinating with each other.
• An organ is made up of two or more specialized tissues coordinating with each other.
• An organ system is made up of multiple organs coordinating with each other.
• Organ systems make complex living organisms or perform a function necessary for life for an organism.

• Nerve cells (neurons) are long and thin to send signals throughout the body.
• The heart, blood vessels, and blood work together to deliver oxygen and nutrients to the body and to remove wastes.
• Muscle cells have long fibers made of protein that slide past each other to contract or relax.
• Blood is transported through the body through blood vessels.
• Cells are the smallest unit of life.
• Cells all have similar components but become specialized to carry out specific functions.
• Blood vessels help maintain the body’s blood pressure to deliver oxygen and nutrients to cells around the body and also transport waste products away.
• A tissue is made up of many cells of the same type coordinating with each other.
• There are three types of blood vessels: arteries, capillaries, and veins.
• An organ is made up of two or more specialized tissues coordinating with each other.
• An organ system is made up of multiple organs coordinating with each other.
• Organ systems make complex living organisms or perform a function necessary for life for an organism.
• Arteries carry blood away from the heart to capillaries, containing nutrients and water and supplying this blood to the rest of the body.
• The heart, blood vessels, and blood work together to deliver oxygen and nutrients to the body and to remove wastes.
• Capillaries are tiny blood vessels around tissues, allowing Oxygen and CO2, nutrients and water to move in and out of the blood stream.
• Blood is transported through the body through blood vessels.
• Blood vessels help maintain the body’s blood pressure to deliver oxygen and nutrients to cells around the body and also transport waste products away.
• Veins carry blood from capillaries back to the heart, carrying deoxygenated blood from the body back to the heart.
• There are three types of blood vessels: arteries, capillaries, and veins.
• The circulatory system consists of the heart, blood vessels, and blood.
• Arteries carry blood away from the heart to capillaries, containing nutrients and water and supplying this blood to the rest of the body.
• Oxygen moves into the bloodstream, and carbon dioxide moves out into the air for exhalation.
• Capillaries are tiny blood vessels around tissues, allowing Oxygen and CO2, nutrients and water to move in and out of the blood stream.
• Veins carry blood from capillaries back to the heart, carrying deoxygenated blood from the body back to the heart.
• The circulatory system consists of the heart, blood vessels, and blood.
• During this process, oxygen diffuses from the blood in capillaries into the surrounding tissues, and carbon dioxide, a waste product, moves from the tissues into the blood.
• Oxygen moves into the bloodstream, and carbon dioxide moves out into the air for exhalation.
• During this process, oxygen diffuses from the blood in capillaries into the surrounding tissues, and carbon dioxide, a waste product, moves from the tissues into the blood.
