Answer: Capillaries
Explanation: Blood vessels have the same basic structures used to circulate blood of different composition to and away from the heart to the body. Blood vessels are arteries, veins and capillaries. Arteries carry oxygenated blood from the heart to the body and veins carry deoxygenated blood from the tissues to the heart.
Capillaries are the ones that work with body cells for exchange.They collect nutrients and oxygen from the blood to the cell and also collect carbon dioxide and waste from the cell to the blood which is transported to the vein where it travels via the venous system and goes through the heart, then to the lungs for gaseous exchange.
Therefore the enswer is, capillaries.

Answer:
1). Xeroderma pigmentation.
2). Ataxia-telangiectasia.
Explanation:
DNA repair processes include all the processes, which help in identification and correction of errors or damages in DNA. Defects in DNA repair mechanisms that increase risks for developing cancers and various other disorders. Two conditions related to faulty DNA repair are:
1). Xeroderma pigmentation (XP): XP can be defined as a genetic disorder, due to mutations in genes involved in repair processes. It leads to severe sunburn and freckling due to sun exposure, dry skin and skin pigmentation. People having xeroderma pigmentation are prone for skin cancer.
2). Ataxia-telangiectasia (AT): AT is caused bu mutation in ATM gene (ataxia-telangiectasia mutated) gene, which in involved in nucleotide-excision repair pathway. It leads to severe disability in children and increases risk for developing lymphomas and leukemia.
