  • Circulation Of The Blood In Superficial Capillaries
    1,459 words
    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 th...

  • Coronary Artery Disease And Stroke

It also is involved with the immune ...
  • High Blood Pressure

    HIGH BLOOD PRESSURE The definition of High blood pressure is a measurement of the force applied against the walls of the arteries as the heart pumps blood through the body. The pressure is determined by the force and amount of blood pumped and the size and flexibility of the arteries. The blood pressure is continually changing depending on activity, temperature, diet, emotional state, posture, physical state, and drugs. The blood pressure is usually taken while the person is seated with the arm ...

    Describe the action of the heart in terms of collecting blood, pumping of blood, and opening and closing of valves In mammals, with double circulation, the heart is divided into right and left sides with 2 atria and 2 ventricles. This division of the heart prevents the oxygenated blood on the left side from mixing with the deoxygenate d blood on the right side. The muscular heart pumps the blood into a system of arteries, which branch into arteries. Within the tissues the arterioles branch into ...
  • One Red Blood Cell At A Time

A circulating connective tissue-blood-interacts with tissue fluid, making continual deliveries and pickups that help keep conditions tole...
  • Coronary Heart Disease

    The Heart and Its Diseases Cardiology has intrigued me since I was a small child. It has been my goal to become a cardiologist ever since the first grade. Cardiology is more than just studying the heart. To define it properly would be to say that cardiology is the study of the heart, its action, and its diseases (Clayman 52). The heart is located in the center of the chest, just behind the sternum, sitting in a hollow cavity between the lungs. The heart is slightly larger than your fist. It is a...

  • High Blood Pressure

    High blood pressure (also known as arterial hypertension) is described as an increase in the pressure of blood in the arteries.

  • Related Medical Conditions To High Blood Pressure

    High blood pressure is unlike any other disease. It can be extremely serious, but normally does not affect how you feel day to day. It is often referred to as "the silent killer" (1), because there are no symptoms in the early stages of the disease.

This condition in the unaware person may be slowly causing serious damage and putting them at risk of sudden death from stroke or...
