information about humans’ circulatory system. One of the most important systems our body has if not THE most important since one of its organs is the heart. We will focus on senior citizens. As we age‚ our organs’ working mechanism becomes slower and our muscles tend to be less flexible or elastic and that is why we think the information we will provide‚ will be very useful. Some of the talking points will be: • General function of the system and how the organ system contributes to physiological

Circulatory systems move blood around an organism’s body. They are important for continued life of the cells‚ tissues and entire body of any organism. There are two types of circulatory systems. Open and Closed. An elephant is one of the largest land mammals on earth and therefor it has a large body with a large circulatory system. The circulatory system pumps blood through arteries‚ veins and capillaries. The blood transported around the body reaches organs to nourish cells. In return

There are also blood vessels which play an important part in the human body’s circulatory system. The heart serves as a pump; the blood vessels‚ which carry the blood throughout the body; and lastly‚ the blood‚ which is a vital component for the basic functioning of the human body‚ and which is processed after the intake into the human lungs from the atmosphere.

The Circulatory System The human body is made up of many different systems that perform our basic life functions. One such system is the circulatory system. This system transports oxygen and nutrients to organs and tissues within the body and carries away waste products. In performing these functions the circulatory system is associated with other systems in the body. The circulatory system is made up of the heart‚ blood and blood vessels. The heart is the main component of the circulatory
Premium Blood Heart
The Circulatory System The circulatory system in anatomy and physiology is the course taken by the blood through the arteries‚ capillaries‚ and veins and back to the heart. In humans and the higher vertebrates‚ the heart is made up of four chambers the right and left auricles‚ or atria‚ and the right and left ventricles. The right side of the heart pumps oxygen-poor blood from the cells of the body back to the lungs for new oxygen; the left side of the heart receives blood rich in oxygen from

Circulatory System Composition of Blood Red Cells -These are tiny‚ disc-like cells which do not have nuclei. -In their cytoplasm is the haemoglobin‚ a protein combined with iron. Haemoglobin combines with oxygen in places where there is a high concentration of oxygen‚ to form oxyhaemoglobin. -Oxyhagemoglobin is unstable compound. It breaks down and releases its oxygen in places where oxygen contentration is low. White Cells -They undergo a process of matruation and development in the

1. Within the circulatory system the liver has a unique anatomic location in that it effectively filters all blood coming from the intestinal tract by way of the portal vein before it is pumped to the general circulation. The liver often sees drugs at their highest concentrations‚ since it is the first organ perfused by blood containing the drug after absorption from the intestinal tract. Approximately 10-15% of total blood volume can be presented to the liver at any given time. The entire absorbed

job of the Circulatory System? The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients‚ water‚ and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce. It is an amazing highway that travels through your entire body connecting all your body cells. Parts of the Circulatory System The circulatory System is divided into three major parts: 1. The Heart 2. The Blood 3. The
