bio terms (transport in man)

Carries food and oxygen to all cells in the body ans also carries wastes away from the cells

Body -> vena cava -> right atrium -> right ventricle -> pulmonary artery -> lungs -> pulmonary veins -> left atrium -> left ventricle -> aorta -> body

Receives oxygenated blood from lungs via pulmonary veins

carries oxygenated blood from the lungs to the heart

pumps blood to all parts of the body except lungs via aorta

• carries oxygenated blood
• biggest artery (to withstand highest blood pressure because it is near to the heart)

• prevent backflow of blood to left atrium
• It opens because of blood pressure

• carries oxygenated blood
• consists of pulmonary veins, bicuspid valves, aorta, left ventricles and atria
• pumps blood to all parts of the body thus has thicker muscular walls than the right part

Receives deoxygenated blood

pumps blood to lungs via pulmonary artery

carries deoxygenated blood to lungs

• prevent backflow of blood to the right atrium
• It opens because of blood pressure

Superior Vena Cava - return blood back to the Right Atrium from the upper part of the body.

Inferior Vena Cava - carrying the blood back to the Right Atrium from the lower part of the body

• Carries deoxygenated blood
• Consists of Pulmonary arteries, tricuspid valves, vena cava, right ventricle and atria

• Prevents backflow of blood(blood is moving towards pulmonary artery and aorta)
• It opens because of blood pressure

• 
• ventricles contract, valves closes.
• present in veins

To prevent oxygenated and deoxygenated blood from diffusing and mixing

• Carries oxygenated blood away from the heart to all parts of the body (except for pulmonary arteries which sends deoxygenated blood to the lungs)
• has thick muscular walls because it has to withstand high blood pressure (especially for aorta because it is near the heart)
• small lumen

• Carries deoxygenated blood towards the heart from all parts of body (except for pulmonary vein which sends oxygenated blood from lungs to heart)
• has thin muscular walls because it resist the lowest blood pressure thus, needing valves to prevent backflow

• carries oxygenated blood from arteries to cells
• carries deoxygenated blood from cells to veins
• has one cell thick wall (endothelium) thus, fluid, platelets or white blood cells, substances can pass through the cells. Because of the one cell thick wall, it allows efficient exchange of materials.

• red blood cells
• white blood cells - lymphocyte and phagocyte
• platelets
• plasma

• To transport oxygen from the lungs to the rest of the tissue cells
• circular and biconcave
• contains a red pigment, haemoglobin which binds to 4 oxygen molecule and will release oxygen when passes the cells.
• absence of nucleus so more haemoglobin can be in the red blood cell which will allow efficient transport

• Sickle cell
• contains less oxygen because of the deformed shape(sickle).
• Patients die because oxygen transportation is not efficient.

• Lymphocyte
• produces antibodies

• Phagocytes
• 
• has a lobed nucleus
• carry out phagocytosis which engulfs and ingest foreign particles

makes blood clot whenever there is a wound

• transport food substance such as glucose from the gut to the body
• transport waste product from the cells to rectum
• 90% water
• transports water, nutrients, bicarbonate ions and hormones
