Cardio/lymph Flashcards
What does the circulatory system consist of?
The circulatory system consists of the cardiovascular system and the lymphatic system.
What is the function of the circulatory system?
The function of the circulatory system is to move fluids around the body to provide oxygen and nutrients, remove wastes, fight infection, and maintain homeostasis.
What does the cardiovascular system include?
The cardiovascular system includes the heart and vasculature.
What is the primary function of the lymphatic system?
The primary function of the lymphatic system is to remove excess interstitial fluid and senescent blood cells, and fight infection.
What are the main components of the gross anatomy of the cardiovascular system?
The main components include the heart located within the mediastinum of the thorax and the two systems of circulation: the pulmonary circuit and the systemic circuit.
Describe the heart’s location and its function in blood delivery.
The heart is located within the mediastinum of the thorax, just to the left of the midline. It delivers blood throughout the body via the pulmonary and systemic circuits.
What is the role of the pulmonary circuit?
The pulmonary circuit involves vasculature traveling to and from the lungs, where the heart pumps deoxygenated blood to the lungs to be oxygenated.
What is the systemic circuit’s function?
The systemic circuit involves vasculature traveling to and from all organs of the body, where the heart pumps oxygenated blood to be delivered throughout the body.
How is the heart’s structure described in terms of its shape and composition?
The heart’s shape is similar to a toppled pyramid with specific regions designated as the right atrium, right ventricle, left ventricle, and left atrium, comprising its overall structure.
What is the function of the pericardium?
The pericardium protects the heart against friction and infection, and fixes it within the mediastinum.
