Circulatory System Sample Clauses
The 'Circulatory System' clause defines the components and functions of the body's network responsible for transporting blood, nutrients, and oxygen throughout the body. It typically outlines the roles of the heart, blood vessels, and blood, describing how these elements work together to maintain homeostasis and support organ function. By clarifying the structure and operation of the circulatory system, this clause ensures a clear understanding of how vital substances are distributed and waste products are removed, which is essential for overall health and effective medical treatment.
Circulatory System the studentwill:
a) Identify and state the function of erythrocytes, leukocytes, platelets, and list components of blood plasma.
b) Explain hemostasis.
c) Distinguish between blood types and identify bold groups.
d) Describe the pathway of the blood naming ▇▇▇▇▇▇▇▇, valves, and connecting vessels including the heart.
e) Identify three layers of theheart.
f) Understand the cardiac conduction cycle by explaining what an EKG represents.
g) Relate the effects of various chemicals and physical factors to the rate of the heart-beat.
h) Describe how the body maintains normal blood pressure.
i) Lab Practical: Identify and name the different parts of the heart and blood flow.

Circulatory System. The circulatory system is the means by which material is transported throughout the body. The circulatory system consists of the heart and a network of arteries, capillaries and veins which carry blood throughout the human body. Red and white blood cells and a liquid called plasma are the main components of blood. The circulatory system carries oxygen and essential nutrients to all places in the body and takes waste products away for removal from the body. The circulatory system also is important for the body’s protection from infection as it carries the defensive and repair units to the source of the infection. The circulatory system is the major mechanism by which radionuclides may be transported within the body. Radionuclides may enter the circulatory system directly (i.e. if the skin is broken due either to wounds or injection) or indirectly (via the respiratory or digestive systems). The part of the body to which radionuclides are transported depends on the chemical properties of the radionuclide. For example, calcium is extracted from our food and deposited in bone tissue. Elements which have similar chemical properties to calcium (e.g. strontium, barium and radium) will also go to the bones whether the atoms are radioactive or not. Iodine is required by the thyroid gland in the neck so any intake of iodine will go to the thyroid. In fact, this aspect of radionuclide deposition is very useful for medical imaging and therapy purposes as particular radionuclides may be attached to a special chemicals so that they are transported to the region of interest in the body. Such substances are known as radiopharmaceuticals.
