- Liquid part of the blood
- Carries the blood cells through the blood vessels
- Contains many dissolved substances such as carbon dioxide and glucose
White blood cells:
- Larger than red blood cells
- Have a nucleus
- Some surround and destroy pathogens
- Some produce antibodies that destroy pathogens
- Are fragments of larger cells
- Have no nucleus
- Causes blood to clot when a blood vessel has been damaged
Red blood cell:
- Contains haemoglobin which carries oxygen
- Has a biconcave shape which gives it a larger surface area
- Oxygen diffuses in and out of the cell
- Has no nucleus to give the cell more room for more haemoglobin to carry more oxygen
It is very important in I/GCSE Biology to memorize the structure of heart
- Pulmonary artery ➡️ carries deoxygenated blood from heart to lungs
- Vena cava ➡️ brings deoxygenated blood from body to heart
- Aorta ➡️ carries oxygenated blood from heart to body
- Pulmonary vein ➡️ carries oxygenated blood from lungs to heart
The left ventricle is thicker than the right ventricle as it pushes blood all around the body.
And we're done with this topic! Well Done!
