circulatory/immune systems review

The movement of blood from the legs to the heart goes against gravity. The movement of blood from the legs to the heart goes against gravity. Which structures prevent the backflow of blood? Which structures prevent the backflow of blood?

• cilia lining the blood vessels

• valves in the veins

• lymph nodes near major vessels

• smooth muscle in the capillaries

Which statement correctly describes all of these structures in human blood?

• They perform specific functions that aid in maintaining homeostasis.

• They are useful in the digestion of oxygen.

• They use all of the DNA present in the cells of the body.

• They produce antibiotics that fight disease.

Platelets are a part of blood that help in the:

• absorption of amino acids

• release of antibodies

• formation of hemoglobin

• formation of a clot

Drugs to reduce the risk of rejection are given to organ transplant patients because the donated organ contains

• foreign antigens

• foreign antibodies

• DNA molecules

• pathogenic microbes

Which statement best describes this event?

• Cell A is a white blood cell releasing antigens to destroy bacteria.

• Cell A is a cancer cell produced by the immune system and it is helping to prevent disease.

• Cell A is a white blood cell engulfing disease causing organisms.

• Cell A is a red blood cell engulfing disease causing organisms.

Volunteers A, B and D underwent a procedure known as

• cloning

• vaccination

• electrophoresis

• chromatography

Certain microbes, foreign tissues, and some cancerous cells can cause immune responses in the human body because all three contain

• antigens

• enzymes

• fats

• cytoplasm

People with AIDS are unable to fight multiple infections because the virus that causes AIDS
