types of cancers

carcinomas- epithelial tissues (covering body surfaces and lining most body cavities) are most common sites for cancers, affect outer layer of skin and mouth , metastasize through circulatory or lyphmatic system and form solid tumors *sarcomas- occur in mesodermal middle layers of tissues, metastasize primarily via blood in early stages of disease +lymphmoas-develop in lymphatic system infection fighting region of body example is hodgskins -leukemias: blooding forming parts of body, particularly bone marrow and spleen, characterized by abnormal increase in number of white blood cells

testicular cancer pancreatic

most common types, appears as enlargement on side of testis deadlist,

Heart

muscular 4 chambered pump , deoxygenated blood enters right atrium after having been circulated through body, from right atrium blood moves to right ventricle and is pumped through pulmonary artery to lungs where it receives oxygen, oxygenated blood from lungs returns to left atrium of heart, blood form left atrium moves into left ventricle and left ventricle pumps blood through aorta to all body parts
