BIOL 2420 Lecture Notes - Lecture 1: Pulmonary Vein, Circulatory System, Arteriole
Document Summary
The cardiovascular system functions in transport and exchange of: materials required by the cells: Serve as building blocks/energy for the cells of the body. If too much blood leaves - pressure decreases and you die. Usually they are off - switch states once there is damaged. If they are always on - blood clots in veins and stuff. Internal body temperature - 37 degrees: waste produced by the cells: Carbon dioxide produced as waste from cell respiration. Non toxic way to carry n into the body. Comes from the breakdown of rbc - component of bile. The cardiovascular system is composed of: blood. Pressurized - if no pressure - no driving force: heart. Produces force to move blood through the circuit. Each side has a atrium and a ventricle. Left side of the heart is the oxygenated blood. Right side of the heart is the deoxygenated blood. When blood leaves the heart leave via the aorta: blood vessels.
