Transport Unit Vocabulary

Blood

• The dynamic structures that create pathways that constrict and relax in order to transport blood throughout the body
• The nonliving fluid component of blood; mainly water with dissolved substances like plasma proteins
• A fluid connective tissue made of living blood cells floating in nonliving plasma that transports a variety of substances critical for maintaining homeostasis
• Smaller blood vessels that branch off of arteries and feed into capillary beds in our different organs and tissues

Plasma

• The nonliving fluid component of blood; mainly water with dissolved substances like plasma proteins
• Red blood cells; carry O2 and CO2 between lungs and rest of body
• Cardiopulmonary resuscitation; the lifesaving procedure used in emergency situations when someone's heart stops beating
• Blood vessels that carry blood away from the heart

Leukocytes

• The inner layer of the heart wall that contracts
• White blood cells; help our body recognize and fight off foreign substances
• Movement of large amounts of gases to different structures that they can then diffuse into
• Red blood cells; carry O2 and CO2 between lungs and rest of body

Thrombocytes

• The smallest blood vessels with the thinnest walls in order to maximize the exchange of materials between the blood and interstitial fluid
• The opposition to flow; the amount of friction the blood encounters as it passes through the blood vessels
• The protein that contains Fe+2 which readily binds to O2, and thus can carry it
• Platelets; cell fragments that help stop bleeding when a blood vessel is damaged

Erythrocytes

• Red blood cells; carry O2 and CO2 between lungs and rest of body
• The diffusion of O2 and CO2 between the alveoli and blood in the lungs and then later the blood and body tissues
• Bind to antigens and clump the cells together for destruction
• Smaller blood vessels that branch off of arteries and feed into capillary beds in our different organs and tissues

Hemoglobin

• The protein that contains Fe+2 which readily binds to O2, and thus can carry it
• Rhesus antigens on red blood cells that determine if you make anti-Rh antibodies and thus have (+) or (-) blood type
• The amount of air that can be held in your lungs
• The smallest blood vessels with the thinnest walls in order to maximize the exchange of materials between the blood and interstitial fluid

Hematopoiesis

• The opposition to flow; the amount of friction the blood encounters as it passes through the blood vessels
• Responsible for the heart's pumping
• Blood cell formation
• Movement of large amounts of gases to different structures that they can then diffuse into

Erythropoietin

• Cardiopulmonary resuscitation; the lifesaving procedure used in emergency situations when someone's heart stops beating
• the total volume of air that can be expelled from your lungs forcibly after you take your deepest breath
• the hormone that regulates the formation and destruction of red blood cells
• White blood cells; help our body recognize and fight off foreign substances

Hemostasis

• Bind to antigens and clump the cells together for destruction
• Movement of large amounts of gases to different structures that they can then diffuse into
• The fast and localized process the body uses to stop bleeding
• When the heart relaxes

Antigens

• Anything that the body perceives as foreign that activates an immune response; Glycoprotein and glycolipids markers/tags on our cells
• Movement of gases, occurring at short distances
• the total volume of air that can be expelled from your lungs forcibly after you take your deepest breath
• Bind to antigens and clump the cells together for destruction
