ANAPHY - Chapter XIII - Blood Vessels and Circulation

Blood vessels outside the heart are divided into two classes:

• Pulmonary vessels

• Pulmonary circulation

• Systemic vessels

• Systemic circulation

It transport blood from the right ventricle of the heart through the lungs and back to the left atrium.

• Pulmonary vessels

• Pulmonary circulation

• Systemic vessels

• Systemic circulation

It transport blood from the left ventricle of the heart through all parts of the body and back to the right.

• Pulmonary vessels

• Pulmonary circulation

• Systemic vessels

• Systemic circulation

The pulmonary vessels and the system vessels constitute the (a)   .

The circulatory system functions:

• - Protection against foreign substances

  - Clot formation

  - Regulations Blood supply

  - Routing blood

  - Ensuring one-way blood flow

• - Transport of gases, nutrients, and waste products

  - Transport of processed of molecules

  - Transport of regulatory molecules

  - Regulation of pH and osmosis

  - Maintenance of body temperature

• - Generating blood pressure

  - Routing blood

  - Ensuring one-way blood flow

  - Regulations blood supply

• - Carries blood

  - Exchange nutrients, waste products, and gases with tissues

  - Transport substances

  - Helps regulate blood pressure

  - Directs blood flow to the tissues

What are the three main types of blood vessels:

• Super vena cava

• Arteries

• Capillaries

• Inferior vena cava

• Veins

It carry blood away from the heart; usually, the blood is oxygenated.

• Super vena cava

• Arteries

• Capillaries

• Inferior vena cava

• Veins

Are normally classified as elastic, muscular, or arterioles, although they form a continuum from the largest to the smallest branches.

• Super vena cava

• Arteries

• Capillaries

• Inferior vena cava

• Veins

It is where the blood flows arterioles to ____ and it is where exchange of substances such as O2+, CO2, nutrients, and other waste products occur between the blood and the tissue fluid.

• Super vena cava

• Arteries

• Capillaries

• Inferior vena cava

• Veins

It has thinner walls than do arteries. Blood flows through this is more slowly, and there are far more of them than of any other blood vessel type.

• Super vena cava

• Arteries

• Capillaries

• Inferior vena cava

• Veins
