POST TEST SCIENCE 9 PART 1

This artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation.

RBCs are red because they contain a protein called ______

The most abundant of the WBCs. They combat bacterial and fungal infection.

A RBC has an average life span of _____ days.

This chamber receives oxygenated blood from the lungs via the pulmonary veins and pumps it into the left ventricle.

Also known as erythrocytes, carries oxygen to the body cells. They collect the waste gas, carbon dioxide and transport it back to the lungs, where it is eliminated through exhalation.

This chamber receives deoxygenated blood from the body through the superior and inferior vena cavae and pumps it into the right ventricle.

Develop into macrophages that can move out of the blood vessels in to the site of infection

The strongest chamber of the heart, it pumps oxygen-rich blood into the aorta and out to the rest of the body.

A large vein that carries deoxygenated blood from the body back to the heart

Located between the right atrium and right ventricle, it prevents the backflow of blood into the right atrium when the right ventricle contracts.

Located between the left atrium and left ventricle, it prevents the backflow of blood into the left atrium when the left ventricle contracts.

The largest artery in the body, it carries oxygen-rich blood from the left ventricle to the rest of the body.

Defend the body against parasitic infections

These veins carry oxygenated blood from the lungs back to the left atrium of the heart.

This chamber pumps deoxygenated blood into the pulmonary artery and towards the lungs.

Carries blood into the heart and generally transport oxygen-poor, carbon dioxide-rich blood. Veins have valves to make sure that blood travels in only one direction even against gravity.

Carries deoxygenated blood from the head, neck, arms, and upper chest back to the right atrium of the heart.

Also known as leukocytes, battle infection by attacking and destroying germs or foreign particles that enters the body.

Tiniest blood vessels, and where gas exchange takes place between the blood and the tissues.

Natural killer cells, B cells and T cells. They control several types of tumors and attack microbial infections.

Located between the right ventricle and the pulmonary artery, it prevents backflow of blood into the right ventricle after it has been pumped into the pulmonary artery

Carries blood away from the heart and transports oxygen-rich blood. They have thicker muscular walls.

Located between the left ventricle and the aorta, it prevents the backflow of blood into the left ventricle after it has been pumped into the aorta
