Test your knowledge on Human Circulatory System Transportation. Blunt trauma can cause injury/significant bleeding that is unseen inside a body cavity. What is a heart attack and what does it have to do with the circulatory system? In vertebrates blood and lymph (the circulating fluids) have an essential role in maintaining homeostasis (the constancy of the internal environment) by distributing substances to parts of the body when required and by removing others from areas in which their accumulation would be harmful. The human heart consists of four chambers two ventricles and two auricles. Your heart and blood vessels make up the circulatory system. Fluid may leave the blood, usually with food and other organic molecules in solution, and pass to the tissues, from which it returns in the form of lymph. An individual with high blood pressure (hypertension) is expected to benefit from the administration of __________ inotropic drugs that __________ the hearts workload.
